526 RHYNCHOPHORA. 
Six specimens, the two from Guatemala being in very fresh condition and more closely 
squamose than the others. This species would be perhaps almost equally well placed 
in Metriophilus, near M. fugax, the tibial carina being narrow and uninterrupted. 
7. Zascelis glabrata, sp.n. (Tab. XXVI. figg. 8; 84a, hind leg.) 
Oblong-ovate, somewhat depressed, shining, black, almost bare. Head closely, somewhat finely punctate, the 
eyes depressed and widely separated ; rostrum curved, rather slender, slightly longer than the prothorax, 
thickly punctate, the antenne inserted at the middle, joints 1 and 2 of the funiculus subequal in length, 
the club ovate. Prothorax transverse, much narrowed in front, the sides rounded anteriorly and parallel 
behind, the base strongly bisinuate ; closely impressed with coarse, rounded, separate punctures, except 
along the narrow smooth space down the middle. Scutellum small, narrow, cariniform. Elytra 
considerably wider than the prothorax, narrowing from before the middle and also obliquely narrowed at 
the base ; with rows of coarse oval punctures placed on shallow strix, the interstices thickly punctate, 
flat on the disc, convex at the sides and apex. Beneath coarsely, sparsely punctate. Ventral segments 
1 and 2 connate at the middle. Legs short and stout; femora feebly dentate; anterior tibia rounded 
along their outer edge; intermediate and hind tibie widened externally to near the apex and then 
abruptly semicircularly excavate, the emargination limited at each end by a sharp tooth. 
Length 6;,-72, breadth 23-31 millim. (¢ 2.)

Four specimens, three of which are from Chiriqui. This insect is recognizable by 
its almost glabrous surface, the peculiar form of the intermediate and hind tibie, and 
the connate first and second ventral segments of the abdomen. The fulvous cilia at 
the apices of the four hinder tibie are visible from above. There are allied unnamed 
forms from Brazil, from the Fry collection, in the British Museum. 
THEGILIS, gen. nov. 
Head convex; eyes large, prominent, finely facetted, somewhat widely separated ; rostrum moderately stout, 
subcylindrical, strongly curved, nearly reaching the metasternum ; antennx inserted at about the middle 
of the rostrum, joints 1 and 2 of the funiculus subequal in length, the club ovate ; prothorax transverse, 
deeply sinuate at the base, the median lobe produced, the ocular lobes not very prominent, angular or 
dentiform; scutellum moderately large; elytra with ten rows of punctures; mesosternum elongate, 
horseshoe-shaped ; metasternum moderately long, the episterna broad; ventral segments 2-4 subequal in 
length, the sutures straight and deep; femora very stout, moderately clavate, deeply excavate on the 
lower side before the apex, the intermediate and posterior pairs feebly dentate and shallowly sulcate, the 
posterior pair about reaching the apex of the elytra, and armed with a strong curved tooth in the ¢; 
tibia broad, curved, compressed, sharply carinate on their outer edge, the apical claw short and stout, 
issuing from near the inner angle; tarsi stout ; body ovate, very sparsely squamose, Baridiiform. 
This genus includes a single species of large size, peculiar to Central America. It 
approaches Zascelis, differing from it in the more prominent eyes, the dentiform or 
angular ocular lobes of the prothorax, the very stout legs, the curved tibie, and the 
peculiar armature of the posterior femora of the male. 
1. Thegilis baridioides, sp.n. (Tab. XXVI. figg. 9, 9a,¢; 98, hind leg, 3 .) 
Ovate, robust, moderately shining, black, the narrow exterior tibial carina fulvous ; very sparsely clothed with 
intermixed, coarse, oblong, fulvous or ochreous scales and minute piliform whitish scales, the larger ones
