[Vol. 92 
to give an exhaustive generic description of Cosmiocryptus but spe- 
cies in the Coastal Desert may be recognized by the following com- 
bination of characters: Axillus close to anal margin of hind wing; 
base of 1st gastric tergite without a lateral tooth; mediella moder- 
ately arched to almost straight; mandible stout with lower tooth not 
longer than upper; hind coxa with a strong subvertical groove 
externo-ventrally near base; propodeal cristae never elongately spi- 
niform; 1st gastric tergite rarely with large and dense punctures. 
Ecology and Host Records 
Cosmiocryptus often are found on the branches of shrubs or trees 
or in herbaceous vegetation. Information about habitat preferences 
of many species is given under the discussion of each taxon. 
The only rearing record for Cosmiocryptus in the Coastal Desert 
is from a species of Megalopyge (Lepidoptera: Megalopygidae).
