(Xylota) Quicliuana suhcostalis (Waxkeb), Trans. Ent. Soc. London, n. 



ser, vol. 5, 1860, p. 291, Mexico (In British Museum). 

 (Platynochaetus) Quichuana niger (Giglio-Tos) Bollet, Mus. Zool. ed 



Anat. Comp., Torino, vol. 7, 1892, p. 6, Mexico (In Museo Storia 



Natural, Torino, Italy). 



Antennal joints 1:1.5:4; abdomen black, basal segment yellow 

 pilose. This species may prove to be a synonym of the above. 



{Merodon) Quichuana angiistiventris (Macquaet), Dipt. Exot., suppl. 5, 

 1855, p. 90, South America (Brazil?) (In Museum d'Histoire Natu- 

 relle, Paris). 



A beautiful species, remarkable for the very large and bright 

 golden pilose frontal triangle in the male.

ser. 4, 1857, p. 153. Amazon? (In British Museum). 

 {Merodon) =Quichuana angustiventris (Macquart). 



QUICHUANA KNABI. new species 



Female. — Very similar to Q. calethea Shannon fro"m Panama, but 

 differs in having the antennal joints 1:2:4, the arista equal to length 

 of antenna. In calethea the antennal joints are 1 : 1.5 : 3.5, the arista 

 longer than length of antenna ; legs more extensively reddish yellow, 

 base and apex of hind femur reddish yellow, remainder darkened; 

 entire anterior border of wing infuscated, incompletely infuscated in 

 calathea. 



Length 11 mm.; wing 8 mm. 



Type locality. — Cavinas, Beni, Bolivia (Januar}'^, 1922, W. M. 

 Mann, Mulford Biological Expedition). 



Type.— C2it. No. 28763, U.S.N.M. 



Genus HABROMYIA Williston 



Hahromyia Williston, Trans. Amer. Ent. Soc. Phila., vol. 15, 1888, p. 284. 



Genotype. — HahroTnyia coei'uleithorax Williston (Trans. Amer. 

 Ent. Soc. Phila., vol. 15, 1888, p. 284). 



Two species of this genus are at hand, one of them apparently 

 conspecific with the genotype. The genus "may be separated from 

 Mallota by its elongate and nearly bare body, head broader than 

 thorax, eyes of male narrowly separated, eyes bare ; third vein deeply 

 looped; first submarginal cell open; anterior border of wing infus- 

 cated, posterior half hyaline. 



HABROMYIA COERULEITHORAX WUIiston 



The genotype coeruleithorax has the head and thorax black, a 

 yellow spot above antennae. 



HABROMYIA FLAVIFACIES, new species 



Male and female. — Easily separated from coeruleithorax by hav- 

 ing the front, face, and antennae bright yellow in the male, brownish
