1892.] COLEOPTERA FROM CENTRAL AFRICA. 93 



14. Pachytoma obscura, n. sp. 



Obscure ferrugineo-testacea ; scutello, corpore subtus, pedibus 



antennisque {his basi testaceis exceptis) nigris ; prothoracis 



lateribus a basi usque ad tertiam partem anticam divergentibus, 



deinde convergentibus ; elytris crebre puncfulatis. 



Resembles P. gigantea, lUig., but differs from this and the other 



species known to me by the shape of the pronotum, which, narrowest 



at the base, gradually widens up to ahout the anterior third or fourth, 



thence narrowing again to the apex. The last ventral segment 



of the abdomen in the female has a rather deep longitudinal pit or 



groove along the middle of the apical half of the segment. 



15. Ornithognathus generosus, Thoms. 



Family Hispid^. (By H. S. Gorham, F. Z.S.) 



16. Cryptonychus murrayi, Baly. 

 Cryptonychus murrayi, Baly, Cat. Hisp. p. 7Q, t. 6. f. 5. 

 One example and one var. 



The variety has the thorax narrower, more thickly punctured all 

 over the surface, with confluent elongate sculpture ; the elytra have 

 a large dorsal black patch, widest in the middle and extending to 

 the sides, and the apex more narrowly black than in the type ; and 

 the whole upper surface is more opaque. It possibly represents a 

 different species. 



All the species of Cryptonychus hitherto described have been from 

 the West Coast of Africa ; the specimens of the late Mr. Murray 

 are now in my collection. 



Family Cassid^. (By H. S. Gorham, F.Z.S.)
