Species 36. 
Species 37, 38. 
1. Lechriops copturoides, sp. n. (Tab. VI. figg. 13, 13 a-c, 2.) 
Subovate, piceous or nigro-piceous, the antenne, tarsi, and apical margin of the elytra ferruginous; the 
vestiture close, the scales on the elytra very small, oval, and somewhat imbricate: the whitish or pale 
ochreous scales on the prothorax condensed into three broad vitte, and those of the elytra into a broad 
sutural stripe and two or more broad, transverse or oblique fasci, which are sometimes divided or much 
interrupted, the rest of the upper surface brownish or fuscous; the flanks of the prothorax and the 
under surface densely clothed with coarser whitish scales, the vestiture of the legs also whitish. Eyes 
very large, occupying the whole of the side of the head, subcontiguous. Rostrum rather slender, 
rugulose and subcarinate at the base. Joint 2 of the funiculus elongate, about as long as 3-5 united, 
4 longer than 3 in the 9, 5-7 transverse. Prothorax short, narrowing from the base, hollowed at the 
apex, and with broad prominent ocular lobes; densely, rugulosely punctate, and subcarinate. Elytra 
somewhat rounded at the sides, blunt at the tip, depressed along the suture; deeply punctate-striate, 
the striae narrow, the interstices broad, rugulose, and feebly convex. Rostral canal deep, the walls 
prominent, the cavity in the metasternum extending backward beneath the surface. 
Length 23-37, breadth 13-14 millim. (d 9.) 
Hab. Mexico, Toxpam in Vera Cruz (Sallé); Panama, Bugaba, Volcan de Chiriqui 
(Champion). 
Fifteen specimens, eight of which are from Chiriqui. ‘This species is very like some 
of the smaller Copturz, but the rostral canal is so deeply excavate posteriorly that the 
rostrum can be completely locked in at the will of the insect. The fourth joint of 
the funiculus is slightly elongated in the female, as in Copturus gracilis and C. fulvo- 
maculatus. The markings are variable, but there is always a transverse dark patch 
near the apex of each elytron. 
2. Lechriops oblongulus, sp.n. (Tab. VI. fig. 14.) 
Oblong, dull, black, the alternate elytral interstices rufescent, the apical half of the rostrum, the antenne, 
tibia, and tarsi ferruginous ; the head with a line of fulvous scales around the eyes; the prothorax 
thickly clothed with rather long, coarse, fulvous scales, with a few white ones intermixed on the disc ; 
the elytra with a small transverse white patch at the middle of the suture, a white dot in a line with it 
on the eighth interstice and another on the shoulder, and for the rest sparsely clothed with small, 
narrow, intermixed fulvous and cinereous scales; the vestiture of the under surface and legs similarly 
coloured. Head rather small; eyes moderately large, narrowly separated ; rostrum rugulosely punctate 
and carinate at the base; joints 1 and 2 of the funiculus equal in length. Prothorax transverse,
