above, closely, confluently punctate to the tip, the apical portion as wide as the basal. Prothorax longer 

 than broad, rounded at the sides, constricted in front, and sharply margined at the base ; very coarsely, 



w 



irregularly punctate. Scutellum rather large, oval. Elytra elongate, a little wider than the prothorax, 

 subparallel in their basal half ; finely punctate-striate, the interstices flat, broad, each with a row of 

 scattered, small, irregularly placed, vesiculiform prominences (those on the first becoming more numerous 

 on the apical declivity) and with some fine uniseriately arranged punctures visible between them. 

 Beneath sparsely punctate ; metasternum and first ventral segment broadly and shallowly depressed 

 down the middle. Legs moderately stout, the tibiae fringed with short hairs.

Sipalus bracteolatus, Boh. in Schonh. Gen. Cure. iv. p. 809 J . 



S . Rostrum constricted at the base ; the basal portion very coarsely punctate, somewhat flattened, more or 

 less raised or subcarinate down the middle, and shallowly sulcate on each side of this ; the apical portion 

 closely punctured. Tibiae sparsely fulvo-ciliate within. First ventral segment more or less depressed 

 down the middle. 



5 . Rostrum with the apical portion smoother and a little narrower. 



Length 7^-19^, breadth 2f-6| millim. 



Hab. Mexico (Mus. Brit. ; Trvqui), Toxpam (Salle), Vera Cruz (coll. Chevrolat 1 ), 

 Motzorongo, Amatan, Tumbala (Flohr); Beitish Honduras, Rio Sarstoon (Blancaneaux) ; 

 Costa Rica, San Jose, La Uruca (Biolley). 



Apparently not rare in Mexico. This species is chiefly recognizable by the shallowly 



- 



bisulcate, subcarinate, basally constricted rostrum, the coarsely punctured prothorax, 

 and the numerous minute griseous spots along each of the elytral interstices, these 

 being uniseriately arranged on the outer part of the disc and often becoming more 

 crowded and biseriate towards the suture. In one very small narrow example from 

 Tumbala the disc of the prothorax, and also the median portion of the under surface, 

 is comparatively smooth.

6. Mesocordylus dispersus, sp. n. (Tab. VIII. figg. 18, 18 a, s .) 



Extremely like M. bracteolatus, but differing as follows: — Rostrum relatively broader, very coarsely, confluently 

 punctate, without trace of sulci in either sex, more or less flattened or depressed behind the middle ; 

 elytra with the minute griseous spots not quite so numerous and more irregularly arranged over the 

 whole surface, usually clustered into two rows along the first (sutural) interstice ; tibiae more closely 

 fringed with fulvous hairs within in the S . 



Length 12£-25|, breadth 4-8 millim. ( <J § '.)
