French Guiana, St. Laurent du Maroni, July, one ? , ex coll.

 which we only know at present from British Guiana. 



MEGALOPYGIDAE. 



4. Unduzia dyari sp. no v. 



We are indebted to Dr. Harrison Dyar for information on this 

 interesting species, which is allied to gistinda Dyar (Proc. U. S. Nat. 

 Mus. 47, p. 252, 1914, Panama Canal Zone). This, however, is the 

 same as pellucens Dogn. (Mem. Soc. Ent. Belg. xix, p. 171, 1912, 

 Venezuela), so Dr. Dyar informs us, and will therefore sink as a 

 synonym. 



? . Wings more pointed and outer margin more oblique than in 

 gistinda. Fore wing with vein 7 and 9 arising from the same point 

 on 8, whilst in gistinda 9 arises from the base of the stalk in one 

 specimen, shortly on the stalk in a second, and distinctly from the cell 

 in a third. Hind wing with discocellulars less strongly angled than 

 in gistinda. 



Wings transparent, covered with short blackish hair, and without 

 any trace of markings. Antennae, head, thorax, abdomen, and legs 

 chaetura-black (xlvi) ; tegulae with a tuft of white hair ; legs fringed 

 with white hair on the outer side, especially the tibia. 



Length of fore wing : 27 mm. 



Ecuador, one 2 , ex coll. Brabant.
