although there is a fovea as in most species of the genus. 

 I have described tliis in the Entomologist, 1891, under the 

 above name, as Baly described his species from female 

 specimens, in which the antennse are but little dilated ; in 

 the male they are considerably so, and the terminal joints 

 are fulvous. As Baly's name is the oldest, mine cannot 

 stand, although Cncoranc is as good a genus for the species 

 as that of Baly's. 



Mcgalognaflia hirticoUis, sp. n. 



Black, the abdomen flavous ; thorax finely rugose and jDubescent, 

 foveolate anteriorly, elytra closely punctured and finely wrinkled. 



Mai. Antenn;T3 very long, the seventh joint dilated anteriorlj-, 

 hatchet shaped, thorax with a small triangular fovea. 



Fern. Antennae shorter and simple, thorax of nearly similar 

 structure. 



Length 8 millim. 



Head impunctate, the frontal elevations very strongly raised, 

 narrowly oblong, antennte nearly extending to the apex of the 

 elytra, black, the third joint rather longer and more slender than 

 the following three joints, the seventh more strongly dilated at the 

 apex than the rest in the niale ; thorax as long as broad, all the 

 margins nearly straight, the anterior margin thickened at the middle 

 and followed by a small triangular fovea, rest of the surface finely 

 rugose and pubescent ; elytra sculptured like the thorax but with- 

 out the pubescence, the sutural margin accompanied by another 

 ridge near the apex, under-side and the legs Idack, abdomen flavous, 

 the last segment more or less black. 



Hcib. Salisbury, Mashonaland, on Zizyphus {G. 

 Marshall). 



From M. rnfivcntris, Baly, M. ahyssinica, Jac, and M. 

 imbecilla, Weise, this species may at once be distinguished 

 by the pubescent thorax and its sculpture. 



Megalognatha granulicollis, sp. n. 



Head, antenna?, the breast and legs black, tliorax rufous, minutely 

 punctured and granulate, elytra flavous, convex posteriorly, very 

 finely punctured with a small piceous spot below the middle, 

 abdomen flavous. 



Mas. Thorax witli a shallow triangular depression, minutely 

 punctured and granulate. 



Fern. Thorax coarsely rugose wiih a. very deep triangular excava- 

 tion.
