458 RHYNCHOPHORA. 
4. Guioperus klugi. (Tab. XXII. fig. 15.) 
Pycnopus klugii, Gerst. Stett. ent. Zeit. 1860, p. 395°. 
Oblong-ovate, broad, thickly clothed with brownish-white scales, the smooth granules or elevations of the 
- upper surface bare, the elytra each with indications of two subquadrate denuded patches on the disc, one 
before and the other beyond the middle, the vestiture of the scutellum brownish-black. Head rather 
sparsely, rugulosely punctate, faintly foveate between the eyes; rostrum rugosely punctate. Prothorax 
transverse, rounded at the sides anteriorly, much narrowed and slightly constricted in front, subparallel 
behind ; closely granulate. Elytra slightly narrowed towards the base, the humeri obtuse; seriate- 
punctate, the interstices each with a series of smooth tubercles. Metasternal plice dentiform. Tuibie. 
with the submedian tooth sharp, the apical teeth only preceded by pencils of fulvous hairs. 
Length 14, breadth 83 millim. 
ab. Nicaracua, Chontales (elt) —Cotomsia (Mus. Brit.); Anvitues, St. John !. 
- One specimen, agreeing very nearly with Gerstaecker’s description of the typical 
form of G. klugi. Easily recognizable by the four subquadrate almost bare patches 
on the elytra, the latter with each of the interstices seriato-tuberculate, the prothorax 
closely granulate. 
5. Guioperus sexsignatus, sp.n. (Tab. XXII. figg. 16, 16 a.) 
Subovate, black, dull; the prothorax and elytra densely clothed with white scales, except upon the scattered 
granulated or elevated portions of the surface, which are bare, the prothorax with two transverse fascia. 
on the disc (one median, the other, smaller, basal), and the elytra with a subquadrate patch on the disc 
of each before the middle and a post-median fascia, also bare; the sides of the body beneath and the 
legs in part densely albo-squamose, the vestiture of the scutelilum black. Head sparsely punctate, feebly 
foveate between the eyes; rostrum rugosely punctate. Prothorax transverse, rounded at the sides 
anteriorly, narrowed in front; alutaceous, very sparsely granulate. Elytra widest beyond the middle, 
gradually narrowing towards the base, the humeri obtuse; seriate-punctate, the interstices alutaceous, 
transversely wrinkled, the alternate ones each with a series of scattered, flattened, umbilicate tubercles. 
Metasternal plicee not prominent. Tibize with the submedian tooth sharp, the apical teeth only preceded 
by pencils of fulvous hairs. 
Length 114, breadth 64 millim. 
Hab. Mexico, Cuernavaca in Morelos (Sa//é). 
One specimen. Near G. trifasciatus, but with the vestiture almost wholly white 
and differently arranged; the granulation of the prothorax much more scattered; the 
tubercles on the elytra less numerous, larger, flattened, and confined to the alternate 
interstices, each bearing a puncture; the scutellum smaller.

MICROCLEOGONUS, gen. nov. 
Rostrum stout, rather short, feebly curved, the scrobes descending to the lower limit of the large, coarsely 
facetted eyes, the latter almost contiguous above and well-separated beneath ; antennz with the funiculus 
7-jointed, 1 stout, the club ovate, with distinct sutures ; head globose, exposed ; prothorax with feebly-
