PROCEEDINGS OF THE Entomological Society of Washington VOL. 43 FEBRUARY, 1941 No. 2 AEDES (HOWARDINA) ALLOTECNON, A NEW SPECIES OF AEDES FROM COSTA RICA, AND A DESCRIPTION OF THE LARVA, ADULT, AND MALE TERMINALIA OF AEDES QUADRIVITTATUS COQ.' By Henry W. Kumm and W. H. W. Komp. During the course of a mosquito survey of Costa Rica, the senior author collected Aedes larvae from bromeliads in several localities at high altitudes. Adults were obtained from these larvae, and it was noted that although the imagos were nearly identical, the larvae from which they were reared were of two quite different kinds. Further search in similar locations resulted in obtaining a good series of both kinds of larvae, and of adults reared from them. Because of the very distinct larval differences, undoubtedly two species are present, the larvae of which may occur in the same bromeliad. The adults resemble each other closely, conforming to the description by Coquillett (1) and that given by Howard, Dyar, and Knab (2) for Aedes {Howardina) qiiadrivittatiis. Slight differences in the mesonotal pattern of golden-scaled lines are present in the adults of the two species, but insufficient material is in hand to permit a state-ment as to the range of variation in this pattern. The junior author examined the material in his collection from Panama, and found that he had collected from a bromeliad on the slopes of Chiriqui volcano in northern Panama a perfect larva of the type also obtained from bromeliads in Costa Rica, which has all the head-hairs in multiple tufts. He also had two males, and a number of females, all in poor condition and with the mesonotum badly rubbed. In addition he had one male and six females taken by Mr. Graham Fairchild at Finca Lerida, near Boquete, Panama, on the other side of the Chiriqui volcano from the locality in which he took his material. Lin fortunately, the mesonotum is denuded in every specimen taken by Mr. Fairchild, so it is impossible to make out the markings. ' The studies and observations on which this paper is based were. conducted with the support and under the auspices of the International Health Division of The Rockefeller Foundation, the United States Public Health Service, and the Gorgas Memorial Laboratory. *A]R 4 19^'
