plate trapezoidal, broader than long, with the hind angles 

 obtuse, rounded. Median keel of the pronotum high, 

 distinctly compressed laterally ; lateral keels formed each by 

 a row of separate, sharj) carinulae and tubercles. Hind tibiae 

 red or orange on both sides E. haematopus L. 



2. (1) Male cerci in the apical half obtusely conical * (fig. 14). 



Male anal plate with the hind angles widely rounded. Lateral 

 keels of the pronotum more or less continuous, interrupted 

 only by furrows. 



3. (4) Median keel of the pronotum high and thick. Hind tibiae 



greyish on the outer side and blackish on the inside, with 

 the base coral-red E. eremobioides Bol. 



4. (3) Median keel of the pronotum thin and low. Hind tibiae 



of the same colour (red or yellow) on both sides. 



E. tuherculatus M. Fern. 



There is one more, probably new, species amongst the 

 collection sent by the Division of Entomology, Pretoria, 

 but it is represented by two females only, and I abstain 

 from describing it. 



AcROPHYMUS, gen. nov. 



Related to Amhlyphymus Uvar., but differing from it in the 

 shape of pronotum, of prosternal tubercle, of the male genitalia, 

 as well as by the lateral elytra and undeveloped wings. 



Finely ruguloso-punctate, but not at all tuberculate. Antennae 

 scarcely compressed. Face slightly reclinate, rather rugose, frontal 

 ridge in profile feebly convex, its surface perfectly flat, rather 

 densely punctured above the median ocellum and sparsely below 

 it, with the margins smooth, convex, feebly and gradually divergent 

 towards the clypeus. Fastigium of the vertex distmctly sloping, 

 elongato-hexagonal, with the surface scarcely impressed, margins 

 slightly raised. Temporal foveolae small, very irregular, coarsely 

 punctured. Occiput with a fine incomplete carinula, reaching the 

 base of the fastigium. Eyes large, oval, distinctly higher than 

 long, and slightly higher than the subocular sulcus, with the fore 

 margin feebly convex. Cheeks scarcely rugulose, sparsely punc- 

 tured, with the oblique sulcus feeble. Pronotum thick, neither 

 laterally compressed, nor constricted; its disc distinctly convex; 

 median keel low, but very distinct, in profile straight or slightly 

 convex, feebly intersected by the three transverse sulci; prozona 



* The male of E. eremobioides is known to me from Bolivar's 

 and M. Fernajidez' descriptions only.
