Two species of this genus, botii inhabiting Bjrneo, have 

 previously been described. The present one agrees with them 

 in all its essential characters, but is much larger, and, indee 1, 

 is by far the largest of the great Lachnosterna group known 

 to me. In its general form and colour it is like 0. princ^'pt, 

 Sharp, but the long erect hairs with which the upper surface 

 bristles distinguish it from all its congeners, now three in 

 number. These hairs arise from very large punctures which 

 are scattered irregularly over the prothorax and front of the 

 head, but upon the elytra are confined to the smooth slightly 

 elevated costse. Another peculiar feature is found in the 

 shape of the prosternal process, which has the unusual form 

 of a transversely placed crescent, the two extremities of wliich 

 are acutely pointed but not much elevated. 



A single specimen was found by Mr. Oiiarles IIos \ 



Octoplasia prolix /, s;). n. 



Yalde elongata, castanea, capite nigro, femoribus flavis, supra glabra, 

 pectore dense flavo-hirto ; capite lato, clypeo leviter bilobato, 

 impunctato, margine reflexo, fronte crebre punctata, lateribus 

 parcissime sed longe hirsutis ; prothorace grosse sat crebre punc- 

 tato, medio paulo impresso, lateribus crcnatis, piliferis, regulariter 

 arcuatis, hand angulatis, angulis antieis acutis, posticis rotun- 

 datis ; scutello grosse punctate ; elvtris longissiniis. lajvihus, 

 parum punctatis, costissat distinctis, tere impuMCtatis, margiuibus 

 exterioribus baud reflexis ; pygidio fortiter crebre puuctato ; 

 processu prosternale breve, conico. 



Long. 3(5 mm. ; lat. max. 15 mm.

1 have seen only a single specimen of this also. It is 

 another large species, but is chiefly noticeable for its great 

 elongation, the elytra being four times the length of the pro- 

 thorax. Tliey have no silky bloom like 0. gigantea, and 

 their puiicturation is rather feeble. Their lateral margins are 

 bordered -with a rather wide membrane, but are not redexe I, 

 as in the other species.
