EGG.—Conoidal, truncated, higher than broad, the base somewhat rounded; marked vertically by 14 ribs, one half of which reach the summit, the others nearly as far; the spaces between the ribs broad, excavated and crossed by ten or twelve fine ridges; the micropyle at top in centre of a rosette of five minute flat cells; and about these are successive irregular rings of cells, each larger than the one next within, to the verge of top; these are six and five sided, and some are sub-triangular, deeply excavated; color greenish-yellow when first laid, soon turning to brown. In shape, this egg is like that of other species of this genus, but it is characterized by fewer ribs than any with which I am acquainted. Duration of this stage 16 to 18 days.

EGG.—Shaped generally like the eggs of this Group, higher than broad, about as 15 to 13, the number of ribs 30, conodial truncated, the middle but little narrower than the base, the upper half sloping rapidly, and convex; about one third the ribs reach the summit, the rest end at from one half to two thirds distance from base; the spaces between the ribs excavated roundly, and crossed by many fine ridges; the micropyle in centre of a rosette of fine minute flat cells, outside of which are four irregular rings of excavated cells, generally long and narrow, varying from sub-crescent to five-sided; color greenish-yellow. Duration of this stage 10 to 11 days, in July.

Saperda Fayi, Bland.—This beautiful Saperda breeds in the small limbs of Crataegus, especially crus-galli and tomentosa, as first observed by Mr. C. D. Zimmermann, Can. Ent., 10, 220; and should it, like some of its allies, acquire a taste for cultivated fruit trees, it would be a formidable enemy, as is evidenced by the way it depredates on thorn bushes. The beetles appear here the last week in May or the first week in June, according to the season, the males preceding the females three or four days.

Hitherto but a single genus(Conops) of this group has received general accepteance among dipterologists. A second genus, Physocephala, was based by Schiner on characters in themselves of but little importance, and which I did not deem sufficient to separate our species in the first paper I published* on the North American forms. A further study, however, convinced me that they were sufficiently constant to warrant their use, particularly in connection with other important ones in the neuration, which I pointed out.

After all, the geographical range of our fauna, as regards the distribution of insects, is but incompletely marked, and the fact that artifical lines cannot limit the habitat of a species is every day made more apparent. The Florida coast is constantly turning up species properly belonging to the fauna of the West Indies, and Texas and Arizona are as often adding Mexican forms to our list. It is, nevertheless, somewhat strange that three such conspicuous species as those hereafter noted should have only recently appeared within our limits, or at least for so long a time have escaped the watchful eyes of our numerous observers.

Botis magistralis, Grote.

Head pale brown, smooth, shining; mouth parts dark brown; cervical shield brown, divided in the middle by the color of the body, which is translucent greenish-white; along the dorsal region two rows of shining pale brown piliferous spots, four on each segment, those on the first segment darker in color. All the spots bear a short light brown hair. Thoracic feet, abdominal and anal legs concolorous with the body. Length 30 mm. Lives singly on Clethra alnifolia, in a number of leaves fastened together with silken threads. Pupated July 6th. Imagos emerged July 17th and 18th.

Egg.—Pure white, ovoid, with flattened base the apex with black dot showing impregnation. Laid in masses, from 25 to 50 on under side of leaf.

Young Larva.—Head black, shining, second segment orange brown in front, cervical shield black. Body color chestnut brown, with the stripes a little darker; anal clasps and thoracic feet jet black. Length 3 mm.

Egg.—Shape of flattened sphere. Diameter, 1 mil. Color, brownish slate. There are thiry-six vertical ribs, each alternate one only reaching the apex; and numerous horizontal parallel stritations. The eighteen ribs which reach the apex there unite with the horizontal lines, forming an irregular network. Duration of this period 241 to 246 days.
