 I. c, pp. 316, 336 (1907). 



The collection contains a pair, male and female, of what appears 

 to be C. mimulus Karsch. They were taken in April, 1914, by F. H.

A single female specimen bearing the label "Congo (Antisdel),

Genus Stenocrobylus Gerstaecker.

 Decken's Reise in Ost-Afrika, III (2), p. 45 (1873); Stal, Bihang Svensk. Akad.

This genus was erected to receive an insect related to representatives 

 of the genus Catantops, but which differs in having remarkably 

 abbreviated hind tibiae, as well as in a few other respects. Since 

 Gerstaecker described his Stenocrobylus cervinus, which was the type 

 of the genus, seven others have been added. Now an eighth is 

 described. 



The annexed table may be of value in separating the species. It 

 will be observed that among the species there is quite a range of 

 variation in tibial length, spine-formulae, and color-pattern.
