 pygidio grosse ocellato-punctato, basi utrinque foveolato. L. 6

Hab. Malabar. 



This insect may be placed in the first division of the genus, 

 although the sculpture of the head and clypeus and the tho- 

 racic punctures do not allow a comparison with any of the 

 described species. The frontal punctures apparently stamp 

 out and obliterate the frontal stria. 



Platysoma Robestorji, n. sp. 



Oblongum, subpar alleluia, nigro-piceum, nitidum ; fronte concava, 

 stria integra ; elytris striis 3 primis dorsalibus integris, 4-5 

 dimidiatis, suturali ultra medium abbreviata ; pygidio margine 

 elevato, a'qualiter punctato. L. 3i mill. 



Hab. Andaman Islands. 



This species is closely allied to P. striate from Celebes ; it 

 is, however, smaller, with head less transverse, the fourth and 

 fifth striae run to the middle of the elytra, and the margin of 

 the pygidium is less elevated. It is named after our late 

 Resident at Port Blow, by whom it was taken abundantly on 

 several occasions. 



Platysoma planisternum, n. sp. 



Oblongo-ovatum, eomplauatum, piceum, nitidum ; antennis pedi- 

 busque rufis ; fronte leviter concava, subtiliter punctulata ; stria 

 transversa tenuiter impressa, recta ; pronoto stria antice late 

 interrupts ; elytris striis 1-2 integris, validis, 3 in medio inter- 

 rupta ; propygidio parce punctato ; pygidio ocellato-punctato, mar- 

 gine sequaliter elevato. L. 5^ mill. 



Hab. Mysol {Wallace). 



The species composing the genus Apobletes are, as Marseul 

 admits, somewhat heterogeneous ; and I believe the present 

 insect may be an Apobletes. The prosternum is flat, slightly 

 rounded at the base, without sculpture, widely (not deeply) 

 sinuate between the coxae. The mesosternum is broad and 

 transverse at the apex, widely and slightly sinuate. Super- 

 ficially it is hardly perceptible that the meso- and metaster- 

 num are not of one piece ; the latter has, however, a lateral 

 marginal stria, which terminates where the suture is beneath 

 the surface chitin.
