Genera and Species of Blattklse. ] 7l 



advantage of cxamiuiiig a very long scries of C. capucina^ 

 Gersf., taken by Dr. Y. Sjostedt in the Kilimanjaro district, 

 and I am convinced that the shape of the abdomen fampliated 

 or not ampliated) is a character of no importance in discri- 

 minating between species of this genus, for it varies with the 

 age of the insect and is largely affected by the way in which 

 the specimens are dried or killed. Some of Dr. Sjostedt's 

 examples were almost completely cylindrical, others had the 

 abdonien distinctly ampliated ; yet there could be no doubt 

 that all were referable to the same species. Similarly, apart 

 from its size and the shape of the abdomen, C. cylindrica, 

 Walk., differs in nowise from C. gibbicoUi's, Stal.

To be distinguished from C. gihhicolUs, Stal, by the an- 

 tennae testaceous at the base, by tlie proportions and shape of 

 the pronotum, the lateral bands of which are broader and 

 anteriorly are more separated from the disk. I have 

 examined the type of C. somali, Sauss., which proves to be 

 identical with Gerstaecker's species.

The following may be added to the original description : — 

 ? . Piccous, nitid, cribrate-punctate. Head and antennaj 

 castaneous, mouth-parts rufo-castaneous. Pronotum slightly 

 broader than long ; lateral bands narrow, slightly elevated, 

 not closely adpresscd to disk ; pronotal channel wide ; two 

 large crescentic pores, close together, on each side of the 

 disk ; posterior angles produced, disk anteriorly carinate. 

 Abdomen less strongly punctate than the thorax. Coxa; and 

 femora piccous ; tibiie rufo-castaneous ; tarsi testaceous.
