Genus Caevilia, Stal. 

 Carvilia eostalis, sp. n. 



Mantis cincta, var. «, Gerst. Decken's Reisen in Ost-Afrika, iii. (2) 

 pp. 14, 15 (1873). 



Long. corp. '52, exp. al. 50 mm. 



Female. — Tawny brown; head with the base of the labrum 

 black, and a black oval transverse depression, on the lower 

 edge of which the two upper ocelli stand ; head transverse, 

 twice as broad as the front of the prothorax. 



Prothorax half as long again as the meso- and metathorax 

 taken together ; suddenly expanded above the anterior coxae, 

 the frontal lobe carinated and granulated above, and the whole 

 length of the prothorax set with rather small teeth on the 

 sides. 



Abdomen expanded, colour darker than the rest of the 

 body. 



Front legs testaceous ; coxae granulated and denticulated 

 behind, and edged in front with a row of about 15 small teeth, 

 of which 4 or 5 are larger than the others, and are black 

 beneath, except at the tips. Coxae marked with three blackish 

 bands above, and below with a spot at the base, and a large 

 dusky space before the extremity. Femora with 3 strong 

 teeth on the upper edge and about 12 on the lower, the latter 

 black beneath. Tibiae with about 14 spines, those towards 

 the extremity black at the tips, and the terminal spine wholly 

 black ; on the upper and outer surface the femora are marked 

 with three blackish bands. 



All the tarsi blackish ; middle and hind legs otherwise dull 

 reddish, with no distinct markings. 



Tegmina blue-black, with traces of a pale transverse band 

 across the centre ; costal area yellowish, and the apex and 

 hind margin tawny brown ; hind wings blue-black, the 

 margins paler, and the costa narrowly reddish. 



Hab. Abyssinia. 



Gerstaecker may be right in treating this insect as a variety 

 of his M. cincta, but it is very different in appearance from 

 the typical form of that species.
