638 RHYNCHOPHORA. 
Hab. Mexico (ex coll. Sturm). 
We have a worn specimen of this species, probably a male, agreeing with the type. 
It may be known by the dull surface; the seriato-foveolate elytra, with convex inter- 
stices ; the coarsely punctate prothorax, each puncture bearing a rather large reddish- 
brown scale; the stout legs, with unidentate femora; the stout, thickly punctate 
rostrum, with the antenne inserted beyond the middle, &c. The outer (tenth) 
row of punctures on the elytra is short. The sides of the prothorax are parallel 
at the base. 
Species of large size, thickly squamose, with the rostrum exceedingly stout, short, and curved, 
the eyes prominent and widely separated, the prothorax subtrapezoidal, quadrinodose, and 
with prominent ocular lobes, the scutellum convex, the elytra broad at the base, subconical, 
with ten rows of punctures and flattened interstices, the mesosternum broad, somewhat 
angularly excised, the ventral segments 2-4 equal in length, the femora unidentate. 
(No. 10.) 
10. Cryptorrhynchus melastome, sp.n. (Tab. XXXI. figg. 16, 16a.) 
Elongate-rhomboidal, robust, moderately shining, black or piceous, the antenne ferruginous; the head and 
prothorax, a very large, common, triangular space at the base of the elytra, and a broad space at the apex, 
densely clothed with fulvous or reddish-brown scales, those on the prothorax long and narrow, the rest of 
the elytral vestiture very dense, fine, white or brownish-white, the prothorax sometimes with intermixed 
white or ochreous scales on the anterior half; the under surface shining, with scattered scales ; the legs 
thickly clothed with intermixed fulvous and white or ochreous scales, the latter condensed into one or two 
rings towards the apex of the femora. Head rugosely punctate, flattened between and above the eyes, 
. the latter transverse and widely separated ; rostrum exceedingly stout, curved, short, not longer than the 
prothorax, rugosely punctate at the base and sparsely punctate thence to the apex, a little smoother in 
the 2, the antennz inserted at or a little beyond the middle, joints 1 and 2 of the funiculus subequal 
in length, the club ovate. Prothorax strongly transverse, narrowing from the base, the latter bisinuate, 
the posterior portion transversely convex and with four oblong, densely squamose prominences in front 
(two on the dise and one on each side), the ocular lobes large and prominent ; closely, minutely punctate, 
coarsely and rugosely so on the flanks, the disc carinate. Scutellum smooth, convex, the cavity large. 
Elytra much wider than the prothorax, convex, laterally compressed, elongate-triangular, the humeri 
rounded; with rows of coarse, somewhat widely separated punctures, the interstices flat, densely, minutely 
punctulate. Beneath very coarsely, sparsely punctate. Legs moderately long, the femora unidentate. 
Length 8-113, breadth 34-5} millim. (¢ 2.) 
Hab. Guaremata, San Juan and Senahu in Vera Paz (Champion); Nicaracua, 
Chontales (Belt); Costa Rica, Caché (Hogers), Carrillo, Azahar de Cartago (Under- 
wood), San José, La Laguna (Biolley); Panama, Volcan de Chiriqui (Champion). 
Numerous examples of this striking species have been received. It has the elytral 
vestiture coloured as in Celosterninus longipennis, but the two insects are not otherwise 
very closely related. The small scales appear to be easily abraded, about half our 
specimens being worn. Prof. Biolley informs me that it is found on a species 
of Melastomacew, OC. melastome will probably have to form the type of a new 
genus.
