The larva of Vespa maculata spins for itself an entire cocoon, a cell lining, plus a lid to its cell. The number of these linings, placed one atop another, shows how often the cell has been occupied by these young wasps. The masses of hard, chalky, red material found in each cell also show by their number how many times the compartment has been used. Each silken lining can be peeled off ; each bag is complete, and at its bottom is this hardened mass of excrement. When one makes a cross-section of the nest, one finds mass upon mass at the bottom of the cells, but each mass is distinct, separated from the others by this tissue.

According to Mr. A. B. Gahan this species is “close to (Hyperteles) Tetrastichus neuroteri Ashm., but the types of that species have two erect bristles on the submarginal vein, the hind tibiae mostly black, and the funicile joints not much longer than broad.”

♂. Head black, shining; ocelli in a flattened triangle behind the eyebridges and separated from them by a width greater khan the diameter of an ocellus; eye-bridges contiguous and three facets wide. Face black, in width extending farther laterad than the middle of the scape. Palpi brownish, first segment short; second broadest, but little longer than wide with distinct sensory spot; third segment not twice as long as broad; fourth more slender, about three times as long as broad.

The following study of Diapterna is based upon the availabile types together with material in the Museum of Comparative Zoology and in the Canadian National and Owen Bryant Collections. The collections of F. S. Carr and J. B. Wallis have also been studied. Most of the characters presented by the species are not well adapted for use in keys, and many of them vary within the species. However, material can be readily and accurately determined without reference to the genitalic characters which, though often feeble, are very constant. It will be noted that the form of the male anterior tibial spur is characteristic in each species. In the descriptions which follow, no mention is made of this spur except a note as to whether or not the apex is turned caudad, a very important feature not shown in the accompanying figures.

The basic list of the Tipulidae of Quebec is that of Winn and Beaulieu, in which a total of two Ptychopteridae, two Trichoceridae and eighty-seven Tipulidae are recorded from the Provinnce. Certain of the records in this list are erroneous, a few others are synonyms, while still additional species are placed in incorrect genera.

This beautiful little aphid was colllected in 1927, by Messrs. J. Stanley and H. Hulbert, and further material was also received from Mr. W. Downes from an American elm growing in the grounds of the Empress Hotel, Victoria, B. C.

In a recent article Spencer records the Dermestid A. scrophulariae L. breeding in houses upon the dead hc'clies of the Cluster fly P. rudis Fab. A similar relationship between Dermestis lardarius L. and the dead adults of several species of Calliphoridae has twice come to the attention of the writer in Alberta.

At the time of my study of the genus Odontæus (published in the Canadian Entomologist, May, 1928) there was before me a single female from Alabama which appeared to be different from anything else in the material.

In a recent article by Barnes and Benjamin (1929, Bull. Brook. Ent. Soc., XXIV, 177) the generic term Trichofeltia is proposed for the species circumdata Grt.
