1. Scolopendropsis Bahiensis, Brandt, HecueS, fee, 



This appears to be a good genus, established by Brandt, as indicated by tin- 

 number of legs, truncated cephalic segment, and absence <>f Spinet to the 

 lateral appendages. It differs from Scolopocryptops in possessing ocelli, and 

 in the form of the cephalic segments. As I have not yet obtained a |p< 

 men, the characters given are drawn up from Brandt's description. 



Subfamilia ,'i. CoaMOCEraALIlfA. 



Segmenta cephalicum basilareque truncata. Antenna 1 7-articulatac. Labium Wguttumj 

 dentibus parvis. Spiracula valvularia. 



The CormocephaUnw differ from the ScoUtpendrhue in having the cephalic 

 segment abruptly truncated and not imbricated. In this respect they resemble 

 the Heterostomince, from which, however, they differ most completely in tin 

 number of joints to the antennae, the structure of the teeth, and the number 

 and structure of the respiratory organs. They seem to form one distinct 

 genus, which is divisible into three groups , first, with the posterior legs -len- 

 der and elongated ; secondly, with the posterior pair of legs short and ela- 

 vated ; and thirdly, a subgenus, Rhomhocephalus.
