232 PACHYTOMA SUTURALIS. 



This species seems to be closely allied to P. dircemoides 

 Harold in its coloration but differs in the following par- 

 ticulars: the head is not grooved behind the frontal tu- 

 bercles and almost entirely black; the antennae are of 

 different structure and comparative length of their joints ; 

 lastly the entire underside and legs of the present species 

 are not flavous but black. 



Another again closely allied species is contained in my 

 collection : 



Pachytoma Batesi, n. sp. 



Below black or piceous ; three basal joints of the anten- 

 nae fulvous ; head and thorax of the same colour ; 2 spots 

 at the former and 5 at the latter black; thorax closely 

 punctured; elytra rugose-punctate, obscure greenish black, 

 the sutural and lateral margin testaceous. — Length 4^2 — 

 5 lines. 



The shape and colour of the elytra of this species is 

 the same as in the preceeding and the one described by 

 von Harold , but there are sufficient differences to distin- 

 guish it and to consider it a distinct species. 



The head in the present species is closely rugose-punc- 

 tate , testaceous , with the exception of a triangular green- 

 ish spot at the vertex and the similarly coloured frontal 

 tubercles; the latter are distinct but not bounded behind 

 by a transverse groove ; the two lower joints of the an- 

 tennae and the base of the third joint is fulvous, in other 

 respect they resemble those of the preceeding species; 

 the thorax is strongly and closely punctured , with the 

 exception of a small central space near the anterior mar- 

 gin, the disk has 5 spots of which a large one is placed 

 at each side and three small ones in a triangle between 

 the larger ones; the elytra are more finely punctured than 

 in the preceeding species and have a small obscure testa- 

 ceous spot at the middle of the base.
