Bui. 2154 This large midge frequently attains a length of 5 or 6 mm and makes a very large gall on the flower heads of Rudbeckia triloba. |It is closely related to A. globulus 0. S. from which it is easily distinguished, according to Osten Sacken, by the darker color of the hind tibiae and tarsi, though in our own series we have failed to find this character of much service. A more strik- ing feature is the much darker mesonotum. A comparison of type specimens inAthe Museum of Comparative Zoology at Cambridge, Mass., showed that these two species are probably distinct though closely related. There may be some difference in the pupal armature. Our studies of material reared from a typical gall show that in A. conspicua the male palpi are three-segmented, the third antennal segment has a length about six times its diameter and that of the female a length of seven times its diameter. There are also differ- ences in the male genitalia. The gall .was taken at Bath, Rens- selaer county, N. Y.,^August 16, 1907 and was received from High-. Fig. 27 Asphondylia conspicua. (original) Breastbone of larva, enlarged spire, Pa., August 17th; adults emerged from August 24th to 30th. Specimens doubtfully referred to this species were taken in a trap lantern at Newport, N. Y., July 2, 1906; captured by Prof. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State Museum.
