1 Homalostylus dentirostris, sp. n. (Tab. V. figg. 31, 31 a, s ; 32, $ .) 



cf . Elongate, subfusiform, opaque above, pruinose, black, the rostrum and legs obscure ferruginous, the 

 prothorax with two indistinct reddish vittae on the disc and another on each flank, and the elytra with a 

 faint, strongly sinuate, lighter stripe on the disc (extending to about the apical third of the suture, and 

 partly surrounding a common, large, heart-shaped, black patch which extends up the suture to the base). 

 Rostrum about as long as the prothorax, stout, abruptly bowed from the rather elongate, broad, coarsely 

 punctate, basal portion, which is acutely, triangularly dilated on each side beneath, the apical portion 

 strongly compressed and sparsely punctate to near the tip. Antennal scape about twice as long as the 

 funiculus, a little narrower than the club, rounded within. Prothorax much longer than broad, nearly 

 as long as the elytra, parallel-sided in its basal half, obliquely narrowed anteriorly, broadly depressed 

 on the disc towards the base, the latter feebly bisinuate ; sparsely, finely punctate. Scutellum long, 



First ventral segment flattened down the middle and with a short, compressed, cariniform prominence 

 towards the base. Femora ciliate beneath. Tibiae curved, the intermediate and posterior pairs dilated 

 and sinuous within. 

 $ . Rostrum with the basal portion shorter, unarmed at the sides, the apical portion almost smooth, sub- 

 angulate near the tip beneath ; antennal scape much narrower, gradually widened outwards ; prothorax 

 a little less elongate ; the tibiae subequal in width ; the sinuous reddish stripe on the elytra more 



distinct. 

 Length 10^-11-^, breadth Sj- millim. 



Hob. Mexico, Santecomapan in Vera Cruz [Salle). 



Two specimens, both in bad condition, the male a typical Homalostylus, the female 

 with the antennae formed very much as in Rhodobcenus. The male has the rostrum 

 acutely, triangularly dilated on each side near the base beneath, the prothorax 



unusually elongate, and the first ventral segment plicate in the middle ; the antennal 

 scape is much narrower than in //. nigrofasciatus. 



3. Homalostylus incertus, sp. n. (Tab. V. figg. 33, 33 a, 6 .) 



Elongate, snbfusiform, robust, opaque above, black, plumbeo-pruinose, the punctures each surrounded by a 

 larger or smaller greyish-brown dot, the elytra with two common, transverse, velvety-black fasciae — one 

 just before the middle, the other (less distinct) towards the apex. Rostrum stout, compressed, a little 

 shorter than the prothorax, curved, bowed at the tip, the moderately widened basal portion coarsely 

 punctured and narrowly sulcate towards the frontal fovea, the apical portion sparsely punctate and 

 without prominence at the apex beneath ; antennal scape moderate^ long, about as wide as the anterior 

 tibia in its outer half. Prothorax as long as broad, narrowed and subtubulate in front, feebly bisinuate 

 at the base, unimpressed on the disc, somewhat closely punctate. Scutellum oblong-triangular, small. 

 Elytra long, a little wider than the prothorax, gradually narrowed from the rounded humeri, finely 

 punctate-striate, the interstices flat, each with an irregular row of punctures, which are all surrounded 

 by a larger or smaller greyish dot. Pygidium long, subconical, setulose at the tip. Beneath sparsely, 

 t rather coarsely punctate ; ventral excavation broad, reaching forwards to near the narrow, conical, inter- 

 eoxal process of the metasternum. Femora fringed with moderately long, and the tibiae with short, hairs. 



Length 12|, breadth 4 millim. ( S •) 



Hab. Mexico, Toxpam in Vera Cruz [Salle). 



* 



One male. A narrow, elongate, robust form, resembling Rhodobcenus auriculatus, 

 B. fortirostris, and others with nigro-bifasciate elytra, but easily distinguishable there- 

 from by the slightly dilated scape of the antenna.

narrow. Elytra a little wider than the prothorax, finely punctate-striate, the interstices obsoletely 

 uniseriate-punctate. Pygidium conical, coarsely punctate, setulose at the tip. Beneath sparsely punctate.
