520 MR. F. P. PASCOE ON THE COLEOPTERA OF PENANG. [Nov. 22, 



confertim punctato et utrinque fortiter spinoso ; scutello nigro; 

 corpore infra toto violaceo. 



Covered with minute erect stiffish hairs, dark but very clear lute- 

 ous, approaching to chestnut-red on the elytra ; head and prothorax 

 dark brassy brown, with numerous small crowded punctures, the 

 latter with a very strong angular spine on each side ; scutellum nar- 

 rowly triangular, black ; elytra covered with minute crowded punc- 

 tures, each with three slightly raised longitudinal lines, the apices 

 broadly truncate ; body beneath and anterior and intermediate coxae 

 dark glossy violet ; antennae and legs uniformly brownish luteous, 

 the posterior coxae black. Length 18 lines. 



Pachyteria insignita. 



P. hirsuta, brunneo-lutea ; capite prothoraceque ceneo-fuscis, hoc 

 ruffoso-punctato et utrinque angulato ; elytris apicem versus 

 niyricantibus ; medi-pectore et abdomine violaceis. 



Resembles the last, but the prothorax with the punctures more or 

 less confluent, giving it a rugose surface, and its sides rounded an- 

 teriorly and produced into a broad angular process, terminating in a 

 blunt tooth or tubercle, the posterior third of the elytra bluish black, 

 their apices narrowly emarginate, the middle of the posterior thighs 

 and three terminal joints of the antennae black, the ante- and medi- 

 pectus of the same brassy colour as the prothorax, and the coxae more 

 or less luteous. Length 18 lines. 



Pachyteria strtjmosa. (PL XLIII. fig. 3.) 



P. hirsuta, brunneo-lutea ; capite ceneo-fusco, prothorace rugoso- 

 punctato, utrinque valde rotundato, mutico, in medio ceneo-fusco; 

 elytris apicem versus nigrescentibus. 



In many respects similar to the two preceding, but the prothorax 

 strongly rounded at the sides, without any spine or tooth, luteous 

 chestnut, with the greater part of the disk dark brassy brown, the 

 same colour as the head, and this portion as distinctly defined as if 

 it had been a piece let in ; posterior third of the elytra or thereabouts 

 black, tinged with purple, their apices narrowly emarginate ; inter- 

 mediate femora and posterior legs, except their tarsi, blackish ; ab- 

 domen and postpectus glossy violet ; medipectus and presternum 

 dark brassy brown ; antennae luteous, with the last three and part of 

 the eighth joints black. Length 15 lines. 



I am unable to separate in any way Mr. Newman's genus Nirceus, 

 founded on a species from the Tenasserim coast, from Pachyteria, 

 which was at that time probably unknown to him. The genus is 

 one of the handsomest among the Coleoptera, and hitherto has been 

 limited, excluding the Niraei, to P.fasciata, Fab., and P. bicolor, 

 Parry*. The latter, from Java, is allied to P. insignita. All the 

 species here mentioned discharged a yellowish acrid fluid when 

 handled — Mr. Lamb believes, from the abdomen. The genus is cha-
