490 RHYNCHOPHORA. 
Hab. Mrxico, Toxpam in Vera Cruz (Sallé'). 
We have received six specimens of this species, and others belonging to the Dresden 
Museum have been communicated by Dr. Heller. In Faust’s collection P. mexicanus 
is placed under the genus Husrenus. 
9. Pseudomopsis conicicollis, sp.n. (Tab. XXIV. figg. 3, 3 a.) 
Rhomboidal, narrow, shining, black, mottled with ferruginous, the antennz also of that colour; thickly clothed 
with intermixed ochreous and whitish scales, the latter sometimes condensed into one or two oblique 
fascize on each side of the elytra and a small patch on the middle of the prothorax at the base, the pro- 
thorax with two patches on the disc behind, and the elytra in one specimen with a narrow space in front 
of and another behind the humeral fascia, clothed with brownish or blackish scales, the elytral interstices 
each with a scattered series of coarse, semierect, white or ochreous scales. Prothorax transverse, conical, 
densely punctate. Scutellum minute. Elytra convex, much wider than the prothorax, subtriangular, 
parallel at the base, the humeri rounded and not prominent ; punctate-striate, the strizs becoming deeper 
and broader near the suture, the interstices almost flat. Femora unarmed. 
Length 23-31,, breadth 1,,-14 millim. 
Hab. GuateMaua, Sabo in Vera Paz, Cerro Zunil, Zapote, Capetillo (Champion). 
Six specimens, varying in the colour of the scales, one only of them, that from the 
Cerro Zunil (which is taken as the type), showing a definite pattern on the prothorax 
and elytra. The dorsal striz, too, appear to be broader and deeper in some examples 
than in others. Shorter and less convex than P. mexicanus, the elytra not dilated 
below the base, striate, and with the raised scales more conspicuous. — 
10. Pseudomopsis similis, sp. n. 
Very like P. conicicollis, but with the prothorax less widened behind and a little shorter; thickly clothed with 
intermixed ochreous and white scales, and sometimes with small patches of blackish scales, the vestiture 
of the elytra in fresh specimens appearing variegate or tessellate (instead of obliquely bifasciate), the 
more or less convex interstices each with an irregular row of coarser semierect scales. 
Length 2-3, breadth 15-14 miilim. 
Hab. Mexico, Toxpam in Vera Cruz (Sallé); British Honpuras, Rio Hondo 
(Blancaneaux); GtateMaLa, Cahabon, Senahu, Sinanja, and Sabo in Vera Paz 
(Champion); Nicaragua, Chontales (Janson). 
Nine specimens, varying in size, in the colour of the vestiture, &c., and perhaps 
belonging to more than one species. The two examples from Chontales may be taken 
as the types. - 
OXYPTERUS. 
Oxypterus, Faust, Stett. ent. Zeit. 1896, pp. 86, 50. 
The various South-American species referred to this genus, which will also include 
Cryptorhynchus asper, Boh., are very similar in general facies, all having the prothorax 
bisinuate at the base, with the median lobe more or less produced, the scutellum 
wanting, the elytra convex and subtriangular, the femora dentate, the metathoracic
