A single example of this isolated form was found. Although agreeing; in essential 

 features with Didymus it has more the aspect of Erionomus. It is large, broad, and 

 little flattened ; the head is normal, the prothorax devoid of punctures, except 

 for a few minute ones in the lateral scars, and the elytra! strise are only slightly 

 punctured, the three exterior dorsal ones being much feebler than the rest. The 

 sides of the elytra are naked, but there are a few hairs at the anterior face. The sides 

 of the meso- and metasternum are hairy, and the latter is without punctures either at 

 the middle or the hind angles.

 E. sansiiarico Har. proxime affinis, sed metasterni angulis posticis parce punctatis 

 abdomineque fere omnino polito ; sat convexus, clypeo 5-dentato, carina media 

 nulla, carinis frontalibus valde arcuatis, angulo obtuso convergentibus, cornu 

 mediano antice conico, postice vix sulcato, a tuberculis lateralibus vix diviso ; 

 prothoracis lateribus grosse sat crebre punctatis, angulis anticis rectis ; scutello 

 polito ; elytris punctato-striatis, punctis dorsalibus subtilibus, lateralibus grossis, 

 scalariformibus ; metasterni medio impunctato, angulis posticis sat sparse 

 punctatis ; abdominis lateribus vix punctatis, segmento ultimo polito, postice

 Hab. Mubuku Valley, E. Ruwenzori, 6000-13,000 ft. 

 Several specimens were collected. 



This species is of the same size and shape as E. sansiharicus Har., from which it is 

 only distinguishable on close examination. It differs by the shield-like space between 

 the frontal carinse being rather less pointed behind and showing no trace of a median 

 carina, by the thinly, instead of closely and coarsely, punctured hind angles of the 

 metasternum, and the almost unpunctured sides of the abdomen.
