Genera and Species of Blattide. iby 
advantage of examining a very long series of C. capucina, 
Gerst., taken by Dr. Y. Sjéstedt in the Kilimanjaro district, 
and I am convinced that the shape of the abdomen (ampliated 
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. Sjéstedt’s 
examples were almost completely cylindrical, others had the 
abdomen 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. cy/indrica, 
Walk., differs in nowise from C. gibbicollis, Stal.

To be distinguished from C. gibbicollis, Stal, by the an- 
tenn testaceous at the base, by the 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. somal’, Sauss., which proves to be 
identical with Gerstaecker’s species.

The following may be added to the original description :— 
?. Piceous, nitid, cribrate-punctate. Mead and antennae 
castaneous, mouth-parts ruto-castaneous. Pronotum slightly 
broader than long ; lateral bands narrow, slightly elevated, 
not closely adpressed 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. Coxe and 
femora piceous ; tibiz rufo-castaneous ; tarsi testaceous.
