JACOBY, PHYT0PKAG0US COLEOPTERA FROM THE CAMEROONS. 227 



truncate; elytra with a deep basal fovea near the suture, 

 dark blue, strongl}- and closely punctate-striate, the punctu- 

 res as usual larger at the anterior portion and within the 

 depression, the interstiees slightly transversely wrinkled, 

 costate at the sides and apex; below fulvous, the legs bluish, 

 the base of the anterior and intermediate femora more or 

 less and that of the posterior ones to a greater extent, 

 fulvous. 



Allied to L. rubricollis Klug., L. affinis Clark and seve- 

 ral other West African species but from all distinguished 

 by the coloration of the head and that of the legs and by 

 the impunctate thorax; the eight specimens before me only 

 differ slightly in the amount of fulvous of the legs and some- 

 times of the antennas. 



Lema camerunensis sp. n. 

 Plate 10, fig. 2.

Length 7—7 1 J2 mill.

 above the eyes, the latter deeply notched, anterior portion of

This Lema is an other species belonging to the L. armata 

 group, but differs in the not tuberculate anterior angles of 

 the thorax, longer antennas and less deeply punctured elytra, 

 the extreme sides of the abdomen are generally more ore less 

 fulvous; whether the present insect is identical with L. sub-
