SUBFAMILY CHRYSOMYINAE 119 
opposite lunule; vibrissae set 2.0 apart. Otherwise similiar to 
male except for normal sexual differences. 
Length. 5-6 mm. 
Distribution. Nearetic and Neotropical: Southern Texas 
through Central America to Brazil. Although not exactly 
coastal in distribution, the majority of specimens I have seen 
or collected have been from along the Gulf of Mexico (Port La- 
vaca, Texas; Tampico, Vera Cruz, Carmen, Cozumel and Chet- 
umal, Mexico), the coastal sections of the Caribbean (Puerto 
Barrios, Guatemala, Gold Fields, Nicaragua and LaGuaira, 
Venezuela), and inland in British Guiana and Dutch Guiana. 
No specimens were collected by me in the mountains of Cen- 
tral America, or along the Pacific coast of Central or South 
America. 
Biology. Little is known of the immature stages or biology of 
this species. The anal area (pl. 33, E) of the puparium is as il- 
lustrated. Adults of both sexes are attracted to carrion and 
they may be easily trapped in meat-baited traps. In nature, 
adults act very similarly to those of Callitroga macellaria and 
they may be captured on low foliage in the vicinity of dead ani- 
mals. Knipling reared larvae on hamburger at Edinburg, 
Texas, March 29 to April 14, 1937 (Bish. No. 27206). The lar- 
val characters given in the key are from Knipling (1939). 
Chloroprocta idioidea (Robineau-Desvoidy) 
Chrysomya idioidea Robineau-Desvoidy, Essai sur les Myodaires, 
Paris, p. 445, 1880. (Type, female from Brazil, in Paris). 
2?Chloroprocta sp. Van der Wulp, Biologia Centrali-Americana, 
Insects, Diptera, vol. 2, p. 296, 1896. (Two males and one 
female from northern Yucatan, Mexico, in the British Mu- 
seum. ) 
Similar in both sexes to fuscanipenms, but differing from 
that species in having the squamal lobes infuscated especially on 
the apical half, and in having the legs dark brown to black. 
Seemingly, idioidea is smaller and the wings appear to be more 
deeply brownish. . 
Length. 5.5 mm. 
Distribution. Neotropical: Quintana Roo, Yucatan, Mexico, 
to northern South America. The species is either uncommon or 
extremely local in distribution, although I have collected speci- 
mens from Chetumal, Quintana Roo Province, Yucatan, Mexico; 
Flores and San Jose, Guatemala; Costa Rica; Panama; Colom-
