128 MISCELLANEA ENTOMOLOGICA, NO. III. 



truncate, the latter with several setiform punctures, the inner 

 tooth of the mandibles strong blunt and bifid, on the left side 

 elevated into a horn. The thorax is rather broadly margined and 

 is more than semi-circular, being narrowed a little at the anterior 

 angles, the apex is emai-ginate, the basal lobe recurved and 

 slightly emarginate in the middle. Elytra elongate-ovate, widest 

 a little behind the shoulders, gradually narrowing to the apex, 

 very feebly striate-punctate, the punctures large, but only visible 

 under a lens, a strongly impressed puncture near each humeral 

 angle and another near the apex, a cluster of seven punctures in a 

 shallow depression on the base, and a row of rather distant ones 

 in the margin. The legs are like those of Carenidium. Abdominal 

 segments punctigerous.

CONOPTERUM LITTORALE, n. Sp. 



Of rather more robust form than (J. violaceum. Greenish black 

 above with green margins, black beneath, nitid all over. Head like 

 the last, but the inner tooth of the left mandible is elevated into 

 a large blunt slightly recurved tooth or horn. The thorax is also 

 similar to the last, but is slightly less transverse, and the basal 

 lobe is not emarginate in the middle. The elytra are elongate- 

 ovate, but more broadly so than in the last, and are narrowed to 

 the apex, feeble strise are visible on them under a lens ; there are 

 no impressed punctures on the disc, an indistinct cluster of seti- 

 gerous punctures at the base and a row of them on the lateral 

 marerins. In all else like the last. 



Length, 10 lines.

CONOPTERUM BICORNUTUM, n. Sp. 



In form this insect resembles Eutoma, but the antennfe and 

 mandibles are those of C onopterum. The colour is cyaneous 

 above, black beneath. The head is as broad as the thorax, the 

 frontal canals are deep and divergent behind, on each side of the
