334 Mr. F. P. Pascoe on Byrsops, 



Dyerocera. 

 Rostrum crassum, clifforme ; scrobes transversa?, ab oculos 

 distautes. Antennae validae ; scapus brevis ; funiculus sex-articu- 

 latus, articulis totis transversis ad clavarn gradatini latioribus. 

 Protborax elevatus, apice truncatus, lobis ocularibus ciliatis. 

 Elytra convexa, ampliata. Tibiae apice extus productae ; tarsi 

 angustati. Rima pectoralis obsoleta. 



This genus would perhaps be better placed in the 

 Brachycerince, as the antennae are only partially genicu- 

 late, and the mandibles, so far as I can make out, are 

 covered by the mentum ; but the six-jointed funicle, the 

 large ocular lobes, and the depression, hardly amounting 

 to a canal, in front of the anterior coxae, have decided 

 me, at any rate provisionally, to refer it to the Byrso- 

 pince. In the exponent of this genus the sculpture of 

 the head and rostrum is very complex; on the elytra 

 there are a number of large and small tubercles, appa- 

 rently arranged in a row, but under a Codington they 

 are seen to be very much mixed. 



Dyerocera gravida. (PI. XL, fig. 9). 

 D. breviter ovata, squarnis rninutis cinereis vestita ; prothorace 

 confuse granulata ; elytris globosis, quasi seriatim tuberculatis. 

 Long. 4 lin. 



Hab. Transvaal. 



Shortly ovate, black, shining, not closely covered with minute 

 asby scales ; head moderately broad ; eyes large, a ridge over 

 each, between them a Y-shaped glossy black raised mark ; rostrum 

 short, arched, the basal half with a glossy black median ridge with 

 two or three tubercles at the sides, anteriorly a well-marked 

 groove, the apex on each side with a porrect cylindrical process ; 

 antennae blackish, the first joint of the funicle scarcely as long as 

 broad ; the club shortly ovate, pointed, and clearly marked off 

 from, although closely contiguous to, the last joint of the funicle ; 

 protborax very transverse, the sides expanded and tuberculate, 

 the disc clouded with about nine irregular glossy tubercles, a row 

 of smaller ones at the base ; elytra globose, the base lower than 

 the prothorax at its junction, covered above with irregular rows of 

 tubercles, several of the smaller more or less granuliform, the 

 larger more or less semicircular at the top, the cavity behind filled 

 with minute hairs, the spaces between the tubercles unequally and 

 more or less deeply pitted, sutural row raised at the base ; abdomen
