rate, slightly elongate, semirounded. Elytra suboblong, sub- 

 depressed, broader at the base than the thorax, with the shoul- 

 ders projecting forward and roughened with tubercles, rounded 

 at the apex to the suture ; the sutural angle rectangular and 

 toothed, the surface irregularly and pretty closely sprinkled 

 with specks of ochraceous fawn-colour disposed somewhat 

 transversely, which become slightly confluent around the 

 shoulder, and form a slightly larger, irregular, not very 

 marked patch in the middle ; it is flecked with ochraceous 

 fawn-coloui", exactly as in Oncideres. Below, the breast has 

 somewhat alternate, subtransverse, converging stripes of yel- 

 low and cinereous following the ridges and grooves, which 

 are continued from the upperside of the thorax. The meso- 

 sternum and metasternum are entirely fawn-coloured. Ster- 

 num with a short, stout, triangular projection, the apical sides 

 of which are slightly raised, and smooth and glabrous. The 

 abdomen has the margins of the segments (except the first, 

 which is entirely fawn-coloui'ed) cinereous ; in the centre a 

 longitudinal broad space is cinereous, passing into fawn- 

 coloured on each side ; and beyond it the stigmata and more 

 or less of the sides are cinereous, with a greenish tinge. The 

 legs are moderate, and of the same cinereous colour. 



Only two specimens received, apparently females. 



This species is the transition link between Oncideres and 

 the other forms of Prosopocera^ on the one hand, and between 

 the latter and Sternotomis on the other ; the upperside reminds 

 one very much of Oncideres^ and the underside particularly of 

 Sternotomis^ the disposition of the colours and the pale-greenish 

 cinereous being very much what was to be seen in some 

 species of that genus. It is a fine species, worthy to be dedi- 

 cated to my friend Mr. Alexander Fry, who first drew my 

 attention to the remarkable affinity between Oncideres and 

 Prosopocera.
