There are two types of thoracic scalin«r in this group, in one the 

 ornamentation is of broad metallic silvery scales {fulgens^ longipalpis, 

 and monetus), in the other the ornamentation is of narrow curved 

 pale scales (all the remaining species possess this latter type except 

 philli'pi^ which shows a combination of the two). The six larvae 

 known are of two types, those with head hair 4 small and lateral 

 comb a triangular patch of fringed scales {fulgens, longipalpis, and 

 pulchrithorax) and those with head hair 4 well developed and lateral 

 comb a row of pointed spines [embuensis, ingrami, and wellmanii). 

 It is felt that any attempt at subdividing this group must await 

 further knowledge of the early stages of the remaining five species. 

 A. monetus has a patch of flat silvery scales at the base of the 

 metapostnotum (i. e., on it) and some specimens of fulgens also have 

 scales in that position. 



The adults and pupae of many of the species of Group C have been 

 treated by Edwards (1941), and the larvae by Hopkins (1936). 



Included species. — A. harnardi Edwards, emhuensis Edwards, 

 fulgens (Edw^ards), ingrami Edwards, longipalpis (Griinberg), 

 jnadagascarensis van Someren, monetus Edwards, nyasae Edwards, 

 phillipi van Someren, pi.ilchrithorax Edwards, and loellwanii 

 (Theobald). 



Croup D (AUREOSTRIATUS-group : HULECOETEOMYIA) 



Australasian, Oriental, Palaearctic, and Neotropical species. 

 Wings not spotted with areas of pale scaling. Scutal marking pat- 

 tern consisting largely of a pattern of longitudinal lines of white 

 to yellow scales, may also be one or three small spots on the anterior 

 margin, a patch on posterior margin of fossa (scutal angle), and 

 a small patch just before the wing base (all of these patches are 

 distinctly insignificant). Sometimes the longitudinal lines are quite 

 diffused in outline (Subgroups II, IV, and VI), and in a few species 

 some individuals have the lines either missing altogether or else ob- 

 scured by general pale scaling. Such individuals will key into Group 

 F. Femora and tibiae not spotted and ringed nor lined anteriorly 

 with pale scales for nearly their whole length (some individuals of 

 quasin^ubithorax have a fairly definite anterior line on mid-tibiae and 

 a less definite line on mid-femora and would possibly key into Group 

 E). Hind tarsal markings various, but in all, except some speci- 

 mens of sintoni, at least the first three segments are banded basally. 



The exact position of v:asseNl Marks witliin the group is in doubt, 

 owing to the male and larva being as yet unknown.
