This species is very near to striale and Rohestorjij tlie 

 most conspicuous differential character being the strongly- 

 elevated margin to the pygidium in the present species. The 

 dorsal strias are three in number, with slight indications of the 

 fourth and fifth at the extreme apex. 



Platysoma exiguum^ n. sp, 



Oblongum, parallelum, subconvexum, ferrugineum, nitidissimum ; 

 fronte subconcava subtilissime punctulata, stria transversa recta 

 fortiter impressa ; pronoto stria marginali Integra pone oculos 

 angulata, lateribus subtilissime punetulato ; elytris striis 1 et 3 

 integris, 2, 4, et 5 ante basin termiaatis, suturali anterius abbre- 

 viata ; propygidio grosse punctate ; pygidio Isevi, profunde bifo- 

 veolato (ut in P. 10-striato) ; prosterao lobo parce punctate 

 marginato ; mesosterno stria Integra late impressa ; tibiis anticis 

 acute 4-, posticis 3-denticulatis. L. 2| mill. 



Hab. Dikoya, Ceylon. Discovered by my brother, A. R. 

 Lewis, in 1878 ; and a second specimen I found myself in 

 the spring of 1882. 



The above is the smallest known Platysoma^ and is allied 

 to 10-striatum, Motsch. ; the mandibles in exiguum are very 

 fine and acute, with one large tooth in the middle. 



Pachycrcerus bellulus, n. sp. 



Oblongus, cylindricus, viridi-cyaneus, nitidus, punctulatus ; fronte 

 epistomoque marginatis, hoc impresso, stria transversa late inter- 

 rupta vel obsoleta ; pronoto stria marginali antice interrupta ; 

 elytris striis 1-4 integris, 5 et 6 basi evanescentibus ; propygidio 

 pygidioque fortius punctatis ; prostemo stria marginali parallela, 

 mesosterno stria antice interrupta. L. 4^ mill. 



Hab. Abyssinia (Bqfray). 



This species in stature is intermediate between nigro-cceru- 

 leus and Rqfrayi, and is closely allied to the latter. The 

 chief differences lie in the fourth and fifth elytral striae, in 

 the prosternal strise, and in the thoracic punctures j the last 

 in bellulus are finer. 



Pachycrcerus Raffrayi has the prosternal stri« sinuate, 

 widening out in the middle j the thorax has a well-defined 

 fovea before the scutellum, and the epistoma is somewhat 

 excavated. In nigro-cceruleus the stria of the mesosternum 

 is well defined and the prosternal lateral striae are parallel, 

 as in bellulus.
