326 RHYNCHOPHORA. 
1. Pseudocentrinus ochraceus. (Tab. XVII. figg. 6, 6a, ¢; 7,74, 2.) 
Centrinus ochraceus, Boh. in Schénh. Gen. Cure, vii. 1, p. 237°. 
Hab. Norta America, Cameron Co., Texas.—Mexico! (Zruqui, in Mus. Brit.), 
Monterey in Nuevo Leon (Hége), Obrajuelo (ea coll. Flohr), Guanajuato (Sallé). 
I have seen numerous examples of this well-marked species from Mexico, including 
the type; and Mr. Wickham has sent me one (a male) from Texas, though the insect 
has not been previously recorded from outside our limits. It is elongate-rhomboidal 
in form, densely squamose above and beneath, the prothorax with two darker vitte 
on the disc, the elytra with intermixed darker or fuscous scales, which are here and 
there condensed into patches. The rostrum is a little smoother in its apical half in 
the female than in the male, and the antenne are inserted at about the middle ia 
both sexes. The ventral segments 1-5 are broadly flattened down the centre in the 
male. ‘The second joint of the funiculus is as long as 3 and 4 united. The elytra 
are flattened on the disc and have rather prominent subapical callosities. The 
scutellum is moderately large and subquadrate. 
2. Pseudocentrinus hybrida, sp.n. (Tab. XVII. figg. 8, 8a, b, ¢.) 
Oblong, subrhomboidal, rather dull, nigro-piceous or black, the tarsi obscure ferruginous ; sparsely clothed 
with small, hair-like, brown scales intermixed with a few longer, coarser, whitish or ochreous scales, 
these latter arranged in a scattered row along each of the alternate elytral interstices and condensed 
into a small spot at the base of the third; the vestiture of the under surface and legs closer and 
uniformly cinereous. Head densely punctate; rostrum stout, curved, about as long as the head and 
prothorax, closely punctate to the tip, the antenne inserted beyond the middle, joint 2 of the funiculus 
short, a little longer than 3. Prothorax transverse, arcuately narrowing from near the base, constricted 
and subtubulate in front ; densely, confluently punctate, except along the smooth median line. Scutellum 
small, subtriangular. Elytra rather long, gradually narrowing from the rounded humeri; finely and 
shallowly punctate-striate, the interstices broad, flat, and densely, rugosely punctate. Beneath densely 
punctate; ventral segments 1-5 broadly flattened down the middle, and 5 sinuato-truncate at the apex, 
in the g, 5 about as long as 2-4 united. Prosternum narrowly sulcate. Anterior tibie sharply 
unguiculate, and slightly curved at the apex, in the ¢. 
Length 3;,—-4, breadth 13-2 millim. (¢ @.) 
Hab. Muxico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Four males and two females. Smaller, less elongate, and more sparsely squamose 
than Ps. ochraceus, the elytra with fine, dark, hair-like scales intermixed with a few 
larger, longer, whitish scales, which are arranged in a scattered series along the 
alternate interstices, the scutellum small. ‘The present species bears a certain 
resemblance to Pseudogerwus macropterus, an insect occurring at the same locality. 
3. Pseudocentrinus deceptus, sp. n. 
Oblong-rhomboidal, rather convex, shining, black or piceous, the antenne and legs sometimes wholly or in 
part ferruginous; sparsely clothed with rather coarse, narrow, setiform, white scales (the elytra in one 
specimen with a few brown scales intermixed on the disc below the base), those on the prothorax condensed 
into a faint submarginal vitta on each side and those on the elytra arranged in a single line down each
