The phenomena of aestivation and overwintering of ants present a most interesting study. The similarities between the two as well as their many differences offer excellent comparisons. Little work has actually been accomplished with ants in this field in spite of the studies of arthropod hibernation instigated by Holmquist (I) and others. The purpose of this paper is to present some of the more important physical and biotic factors involved in the aestivation and overwintering periods of the Occident ant. Pogonomyrmex occidentalis Cresson, in a portion of the Northern Desert Shrub region, near Twin Falls, Idaho.

In May, 1933, my attention was drawn to a peculiar leaf injury to young cotton plants at Presidio, Texas. The leaves showed a striking reddish brown spotting from the upper side that at first glance resembled red-spider injury. The damaged plants were quite localized in one section of a large cotton field. Examinaion revealed the presence of large numbers of lace bugs present on the lower surface of the leaves. This species was identified as Gargaphia iridescens Champion by H. G Barber of the U. S. National Museum. Gibson, 1919, records the food plants as Ambrosia, Solanum, Malva, and sand nettle. According to records in the U. S. National Museum, this species has been collected by McMillan at Brownsville, Texas, on Solanum, string beans, and Ambrosia; on egg plant at Olmito, Texas, by McMillan; on Croton texanus at Tucson, Arizona, by W. D. Pierce.

Oblong oval, convex, piceous opaque. Antennae and palpi rufo-testaceous.

Head moderately convex, densely punctate, the punctures across the occiput coarser, those of the front finer and united longitudinally in groups of two or more, single and still finer approaching the clypeus, the clypeus nearly smooth at middle. Clypeus impresseed in front, broadly emarginate, the angles broadly rounded, sides arcuate ; genae obtuse, not prominent.

Thorax convex, one-third wider than long, sides sub-parallel, feebly arcuate, the edges partly hidden when viewed directly from above; angles obtuse, the hind angles especially so; base broadly arcuate, marginal line distinct ; punctures rather coarse and close at base and sides, a little finer in front.

With his usual kindness Mr. C. A. Frost sent me the subjoined Heteroptera collected by him in Nova Scotia in July 1927 and 1929, at Portaupique and Westchester. The latest data available on bugs from this part are contained in Blatchley's Heteroptera of Eastern North America; the most extensive list thus far pubished is Parshley's 1923 paper, Records of Nova Scotian Heteroptera, which appeared in Proceedings of the Acadian Entomological Society for 1922, pp. 102, 108. The present records have been checked against these; the order of the species, for convenience, is that of Blatchley's Heteroptera.

In a recent paper entitled “A Grouping of the Agrotine Genera,” by Dr. W. T. M. Forbes (1934, Ent. Am. XIV, pp. 1-41) there is considerable discussion of my “Generic Revision of North American Agrotid Moths,” particularly in connection with what the author claims is my idea of the phylogenetic sequence of the genera. Now, while I value highly a number of Forbes' critical remarks and believe that his studies form an excellent check on my own work, I strongly object to being credited with statements which I had not made, due to either a careless reading or a misinterpretation of my text. A number of such misstatements have crept into Forbes' paper and I believe, therefore, that in justice to myself I may be permitted to call attention to these errors.

Length 2.5 mm., width 1.1 mm. Pronotum and elytra equal in width, sides straight and parallel, elytra arcuately narrowed on the caudal third, very broadly obtuse behind; dark reddish brown; pubescence sparse, erect and yellow, more evident about the apex of the pronotum and on the elytral declivity.

The head has the frons broadly, feebly convex, the median line feebly carinate with a narrow, transverse epistomal impression, the entire surface subopaque from minute reticulations, marked with sparse, coarse, shallow punctures with minute setae on the caudal half, more finely and closely granulatepunctate in front, the punctures bearing long yellow hairs erect on the frons, longer and recumbent from the transverse impression, forming the epistomal fringe, the epistomal margin smooth, narrow and feebly elevated; the eyes with a deep triangular emargination.

Lake Timagami is the centre of one of the few extensive pine forests of the Canadian Zone which still remain. The virgin conditions of half a continent make their last stand against lumbering and settlement in such regions as this; a study of its fauna seems, therefore, imperative to Canadian biologists.

This collection, of which a list follows, was made in the summer of 1932 though unfortunately no collecting was done during the period from June 12 to July 21. No attempt at life-history notes is made, but macro- and micro habitat of the adult are recorded where possible. Localities are indicated by initials and described separately.
