This remarkable genus and species which, at least in the adult 

 females, appears to retain the immature form in full, has recently 

 been fully discussed with the original description. This retention of 

 immature form is a feature hitherto unknown in the Panchlorinae, 

 unless, as there stated, it sometimes occurs in Pycnosceliis siirina- 

 mensis Linnaeus). 



Close resemblance is shown to individuals of the latter species 

 lacking organs of flight. The present species is distinguished by the 

 distal abdominal segments being similarly roughened, but not to 

 a like degree, and in consequence not as sharply and decidedly in 

 contrast with the remaining polished dorsal surface, while the 

 caudal margins of these segments are more strongly beaded. The 

 limbs are shorter, the ventro-cephalic margin of the cephalic femora 

 with a fringe of hairs, which does not increase considerably in 

 length proximad, while all the ventral femoral margins are without 

 spines, even distad, except the caudal margin of the caudal 

 femora, which bears mesad a single small spine, rarely with an- 

 other smaller proximal spine. The dorsal genicular spine of the 

 median and caudal femora is slighter. The tarsal claws are more 

 elongate and slender, with a smaller arolium between. The colora- 

 tion is very similar, blackish brown with a chestnut tinge above, 

 much paler below, with occiput and ocellar areas paler than face. 

 The discovery of the adult male of this species is awaited with 

 interest.
