THE CANADIAN ENTOMOLOGIST. 329 The first moth emerged on the nth August, the next on the 17th August, and others on the 19th and 20th August. The average length of the pupal stage was 14 days. In the spring of 1901, the late Mr. T. G. Priddey, of Toronto, sent to the Division a few larvae of A. virguncula. One of these began to spin a cocoon on the 1st May, the moth emerging on the 28th May. Another specimen which began to spin on the 5th May had changed to pupa by the 8th May, and the moth emerged on the 1 st June. In these two instances it will be seen that the length of the pupal stage was much longer than that of those mentioned above. Some of the larvae of the above brood stopped feeding about the middle of August, and acted as if they wanted to hibernate. In September they were put in a cool cellar, but by the middle of October they had all died. These were all mature larvae, and I cannot account for their not spinning up with the others. At Toronto the writer has taken the moths commonly at light about the middle of June. Food-plant. — The larvte described in the present paper, as well as those received in the spring, were fed on plantain and dandelion. A NEW GENUS OF MYRMELEONID/E. BY NATHAN BANKS, EAST END, VA. Hagen, in his "Stray Notes on Myrmeleonidee," published in the Canadian Entomolgist for 1887 (Vol. XIX., p. 210), called attention to the fact that there are several species of ant-lion-flies in this country which lack tibial spurs. He placed these species in Maracanda, McLach., a genus based on one species from Turkestan. McLachlan's description of the genus agrees moderately well with our forms, except in a few minor particulars. But on examining the figure of the Turkestan in-sect it is at once apparent that our forms are not congeneric with it. The figure [Fedtschenko's Reise in Turkestan, Neuroptera, Plate 1, fig. 1] shows that in Maracanda there are five or six crossveins before the origin of the radial sector, and that the first branch of the radial sector arises far beyond the end of anal vein. These characters place the genus in a different section from the species we have included in Maracanda. Moreover, the figure shows that the prothorax is quite broad, and the femora are stated to be lineate with black in the description. The last joint of the labial palpus is said to be much dilated. All these characters are foreign to the species we have wrongly included in Maracanda; therefore it becomes necessary to propose a new genus for our species.
