General coloration of entire dorsal surface shining, polished, jet black, show- 

 ing a chestnut tinge only in a strong light. Head the same but with ocellar spots 

 buffy, clypeus suffused zinc orange and palpi strikingly whitish buff. Dorsal 

 surface of limbs jet black, in some specimens showing a chestnut tinge. Other 

 ventral portion.s deep blackish chestnut, shining, except the coxae in which the 

 latero-external margins and distal portions are pale, ochraceous-buff, in some 

 specimens tinged with zinc orange. In the immature examples from Panama 

 the pronotum, mesonotum, metanotum and limbs are in large part shimng 

 chestnut, translucent laterad, giving them a very different general appearance. 



The enlarging of the male metatarsi only begins in the last 

 instar before maturity, there showing a slight enlargement with 

 slightly increased size of the distal piilvillus. The preceding in- 

 stars show in both sexes the type found in the adult female. 



This insect was found widely distributed by us in Panama, 

 being the most plentiful roach under litter in or near the jungle. 

 Individuals were not as rapid in their movements as the Pseu- 

 domopid and Epilamprid material there found, as would be 

 expected from their heavier structure. 



Specimens Examined: 31; 6 males, 8 females and 17 immature individuals.
