This is a narrow form of the variable B. pustulosus, with the sides of the proth 



parallel at the base and the

large, these being somewhat

the 



prothorax. As the present insect has occurred in 

 Pacific slone 



various localities, especially on the 



of Guatemala, unaccompanied by B. pustulosis, the two forms are here 







retained as distinct. The sexual characters are similar. The type of B. varieguttatus 

 has been communicated by Dr. Sjostedt for comparison. 



32. Rhodobaenus cinereiventris, sp. n. (Tab. VI. figg. 34, 34 a, 6 ; 35, $ .) 



Elongate, somewhat fusiform, opaque above ; black, the prothorax with two broad vittse on the disc (not 

 reaching the base) and another on each flank, and the elytra each with an 3C-shaped mark on the disc 

 before the middle (partly enclosing a common transverse black patch, which extends forwards along the 

 suture to the base) and various other markings at the base and towards apex, sometimes rufous ; the 

 numerous punctures of the upper surface each surrounded by a small, rounded, cinereous spot, the 

 pygidium and under surface with a uniform flavo-cinereous incrustation. Rostrum not longer than the 

 prothorax, strongly arcuate ; moderately stout, the short, broad basal portion closely punctate ; the apical 

 portion almost smooth, unarmed at the tip beneath in the c? , much longer in the $ and with the 

 peduncle of the submentum in this sex armed with a small tooth in front. Prothorax about as long as 

 broad, subconical, the sides becoming subparallel behind, the base feebly bisinuate ; somewhat closely 

 punctate. Scutellum elongate-triangular, Elytra a little wider than the prothorax, oblong, separately 

 rounded at the apex, finely punctate-striate, the interstices each with a row of scattered punctures. 

 Pygidium long, conical, sparsely punctate. Beneath sparsely punctate : first ventral segment shallowly 

 depressed down the middle in the $ . Femora sparsely fringed with long hairs beneath. 



Length 10-11, breadth 3^-3|- millim. ( tf $ .)

 only (as in JR. adsperms and B. nigrolineatus), the rostrum itself being also elongated 

 in this sex.

33. Rhodobaenus albopunctatus 



(Tab. VI. figg. 36, 36 



<*.) 



Oblong-elliptic, opaque above, black ; the prothorax and elytra ferruginous or reddish-brown, the prothorax 

 with a lanciform median vitta, a triangular patch on each side at the base and a spot in front of it on 



the disc (these sometimes coalescent), and a large patch on the flanks, black ; the punctures on the upper
