sides are gently arcuate ; the anterior angles acute and 

 directed forward. The elytra are distinctly broader than 

 the thorax, densely clothed Avith yellowish silky pubes- 

 cence ; the striaa are very delicate.

A specimen labelled Bengal only differs in being a trifle 

 larger, and in being somcAvhat paler in colour. 



ISostea sodalis, sp. no\'. 



Ovata, nigra, nitida, longe pubescens ; thorace hand 

 crebre distincte punctulato ; scutello parvo, triangular! ; 

 elytris fortiter striato-punctatis, punctis dorsalibus minus 

 impressis ; pedibus piceis. 



Long. 2^ lin. ; lat. li lin. 



The thorax is twice as broad as long, gently narroAA^ed 

 in front, the sides very slightly arcuate ; the jjunctures are 

 large, not very close together, not so close as in *S'. JVest- 

 tcoodli (which the species most nearly resembles), but 

 more impressed. The elytra are broader than in S. West- 

 icoodii, and less attenuated posteriorly, very convex ; the 

 punctures forming the strias are not large, and are only 

 lightly impressed near the suture ; they become larger 

 and deeper toAA^ards the sides, but not so much so as in 

 S. Westwoodii ; the interstices are broad, and not convex 

 even at the sides. 



Hab. — Java (J. C. BoAA'ring, Esq.). Brit. Mus. 



Sostea picea, sp. nov. 



Oblongo-OA'ata, picea, nitida, longe setosa ; thorace dis- 

 crete distincte punctato ; scutello subcordato ; elytris for- 

 titer striato-punctatis, punctis dorsalibus minus impressis. 



Long. 2 lin.; lat. 1 lin. 



The punctures on the thorax are distinct but not very 

 strong nor close together, except near the sides; there is 

 a very shalloAv impression near each posterior angle. The 

 elytra are very nearly three times as long as the thorax, 

 parallel for tAvo-thirds their length and then gradually 

 attenuated to the apex ; the punctures forming the rows 

 are someAA'hat delicate next the suture ; they become deep 

 and larger towards the sides but not confluent, and the 

 interstices, although narroAV tOAvards the sides, are still 

 broader than the punctures ; at the apex the elytra are 

 deeply striated.
