Townes’ revisionary study of this taxon (1962: 256-8) summarizes 
the characters that separate C. planosae from other North and Mid- 
dle American Chromocryptus. It defines the species biogeographi- 
cally as a member of the Temperate Deciduous Forest Biome in 
eastern North America from Massachusetts south to Pennsylvania 
west to Michigan, Indiana, Illinois, and Nebraska. It also cites 
numerous host records for C. planosae as a “gregarious parasite” in 
pupae of the bombycoid genera Tolype and Epicnaptera (Lasio- 
campidae) and one rearing from the noctuoid Halisidota (Arctiidae). 
No additional data have accumulated on C. planosae, since the 
publication of Townes’ monograph.

of Mexico I: 458. 
This species is known from 2 females and 1 male collected at 
Sarasota, Florida in McPhail and Steiner Traps during late winter 
and early spring (24 February to 14 April). In 1974 (331-5), I des- 
cribed Chromocryptus weemsi in relation to its northeast American 
relative, C. planosae. The species are closely allied but seem distinct 
on the basis of chromatic, sculptural, and proportional features, as 
summarized in the foregoing key.

Chromocryptus mesorufus Cushman, 1930. Proc. U.S. Natl. Mus. 76: 2. Holotype?: 
Cuernavaca, Mexico (Washington).

Trachysphyrus mesorufus Porter, 1977. Psyche 84(1): 33-5. 
Chromocryptus mesorufus shows great affinity to the eastern 
North American C. weemsi and C. planosae, as well as to C. huebri- 
chi of southern Brasil and northeast Argentina. It occurs in Mexico 
(Cuernavaca), the Lower Rio Grande Valley of south Texas 
(McAllen), and recently has been reported at Miami, Florida in a 
blacklight trap (Carlson 1979: 457). The essential sympatry of C.
