Two further specimens, a male from Nkusi River, Zulu- 

 laiul, and a female taken at liglit, Durban, appear to be the 

 sexes of another distinet species, whicii have the prothoraces 

 shaped exactlv as in " rival is/'' The dimensions of the male 

 are 10 ram. by 3f mm. and of the female 9 mm. by 3.^ mm. 

 The head is, however, more massive, with more conspicuous 

 frontal t'oveai and transverse sutures. The sides of tiie elytra, 

 especially in the male example, are less parallel and taper 

 more to a[)ices, as in '^ conncvus" and other species that 

 follow. The seriate punctures are limited to the third 

 intervals as in rivalis, but the striatioii and puncturation are 

 deeper and coarser. Their coloration is black, faintly iri- 

 descent in the female, but not in the male example. 

 Antennse, palpi, and legs are lighter testaceous yellow, 

 especially the femora of the latter, which are pallid. It is, 

 however, I think, inadvisable to name and describe these on 

 such limited material and coming as they do from different 

 localities. 



Hypolithus imitativus, Per. 



H. imitativus, Per., appears to be a fairly common species 

 in the neighbourhood of Salisbury, S. Rhodesia, the only 

 place I have so far received it from. Specimens vary a good 

 deal in size, and the pubescence, which in fresh specimens is 

 dense, is often so much rubbed off as to be only perceptible 

 in a few isolated spots about or near the margins. The 

 antennse also vary much in the amount of infuscation. 

 Some examples oidy show iucouspicuous linear macules, 

 whilst others have their joints beyond the three first almost 

 wholly infuscate. In the specimens before me (two males and 

 three females), the males are a trifle larger and have the an- 

 tennse only finely lined with black ; the females have these 

 joints wholly infuscate, except at the intersection of the 

 joints. Whether this may be a sexual distinction or simply 

 accidental we must await the result of examination of larger 

 series to determine. Seriate punctures on the intervals of 

 the elytra are absent in all but one male example, in which 

 they are faintly indicated on tlie third and fifth, 



Hypolithus interstitialis, Boh., and H. ovampoanus, Per.
