198 RHYNCHOPHORA. 
20. Pandeleteius armatus, sp.n. (Tab. VIII. figg. 17, 174, 4, 2.) 
Moderately elongate, flattened above, opaque; fuscous, variegated with testaceous, the antenne, tarsi, and 
apex of the elytra almost wholly of that colour, the deciduous mandibles rufescent; mottled with a 
dense clothing of whitish, pale brown, and fuscous scales, the dark scales on the prothorax condensed 
into a broad median vitta, which is bordered on each side by a whitish stripe, the elytra with an oblong 
whitish spot on the fifth interstice at about the basal third and another on the sixth a little nearer the 
base; the upper surface also set with short, scattered, curled, adpressed, inconspicuous hairs, the suture 
of the elytra in @ with a cluster of very long, erect, pallid hairs at the commencement of the apical 
declivity and another at the tip. Head and rostrum together about as long as the prothorax, finely 
punctate, the rostrum triangularly emarginate at the tip, depressed at the base, and canaliculate down 
the middle; eyes prominent. Prothorax strongly transverse, rounded at the sides, abruptly and deeply 
constricted anteriorly, narrow at the base; finely punctate, obsoletely canaliculate, the disc transversely 
‘depressed before and behind the middle; vibrisse long. Elytra much broader than the prothorax, 
transversely depressed below the base, widening to beyond the middle, the humeri prominent ; finely 
punctate-striate, the interstices becoming convex posteriorly ; the apices narrowly and obtusely produced 
in ¢, and armed on the inner edge with a sharp, inwardly-directed, spiniform prominence in 9 
(fig. 17). Anterior femora strongly clavate. Anterior tibize moderately long, feebly curved, unguiculate, 
and armed with from 6-8 small teeth. 
Length 52-6, breadth 21-24 millim. (¢ 9.) 
Hab. Mexico (Truqui, in coll. Fry ; Mus. Oxon.). 
Two females and two males, the latter immature, all more or less injured by pinning. 
The armature of the sutural margin of the elytra of the female (no doubt for 
effectually locking them in repose) is suggestive of the male structures found in 
various Melyrids. P. armatus superficially resembles P. ciliatipennis. 
91. Pandeleteius ornatifrons, sp.n. (Tab. VIII. figg. 18, 18 a.) 
Oblong, piceous, the legs and antenne in part ferruginous; variegated with a dense clothing of pale brown, 
blackish-brown, and cinereous or whitish scales, the whitish scales condensed into a sharply-defined 
triangular or a-shaped mark on the vertex of the head (sometimes extending forward on to the rostrum) 
and two transverse fascie on the elytra (one just before the middle, not reaching the suture, the other 
subapical and oblique), and the dark scales clustered into one or three vittee on the prothorax, a common 
transverse mark at the base of the elytra and a very large saddle-shaped patch between the pale fascia, 
the pale brown scales with a cupreous tinge; the upper surface and legs also sparsely set with short, 
curled, decumbent hairs, the legs annulate. Head comparatively small, together with the rostrum 
shorter than the prothorax, the rostrum short, hollowed and canaliculate, shallowly, triangularly 
emarginate ; eyes prominent. Prothorax nearly as long as broad, rounded at the sides, strongly con- 
stricted at the base and before the middle, sparsely punctate; vibrissee reduced to a few long hairs. 
Elytra much broader than the prothorax, widening to the middle, and more or less inflated posteriorly 
(2 ?), transversely depressed below the base; finely punctate-striate, the interstices feebly convex. 
Anterior femora clavate. Anterior tibia moderately long, curved, unguiculate, and armed with 4 or 5 
_ small teeth. 
Length 43-6, breadth 2-23 millim. 
Hab. Mexico, Chilpancingo and Omilteme in Guerrero (H. H. Smith). 
Ten specimens. Recognizable by the prominent eyes; the comparatively small, 
albo-maculate head; the small, bi-constricted prothorax ; and the sharply albo-fasciate 
elytra, with a common transverse dark patch at the base, which is connected along 
the suture with the saddle-shaped post-median band. The less hairy prosternum, the
