distinctly punctate, the pronotum less narrowed anteriorly and more rounded at the 
sides in front. It has the pronotal groove deeper than in L. sulcatus, from which the 
present insect also differs in its more elongate shape. ‘The pilose elytra &c. separate 
it from Solenonotus. 
LASIOCHILOIDES, n. gen. 
Head (including the eyes) broader than long, the produced anterior portion broad, moderately long, and 
narrowing forwards, the eyes small; rostrum reaching the middle of the metasternum ; antenne with 
joints 3 and 4 very slender, clothed with long projecting hairs. Pronotum trapezoidal, wide and convex 
in front, with a short collar placed behind the rounded anterior angles, the sides margined anteriorly, the 
base arcuate-emarginate. Scutellum flattened behind, Elytra extending beyond the abdomen, with 
the clavus, corium, embolium, and cuneus distinctly punctured, pilose, the embolium closely ciliate along 
the outer edge, the membrane with a single distinct nervuare. Wings with the hamus issuing a little 
beyond the decurrent nervure. Orifice of the metastethium long, curving forwards externally. Abdomen 
with several very long bristly hairs at the apex, the terminal genital segment asymmetrically formed in 
the male. Legs short; anterior and posterior femora greatly, the intermediate pair more feebly, 
incrassate, the anterior pair denticulate along their lower edge ; anterior tibie minutely serrulate along 
their inner edge, the apex widened and with a short spongy fossa on the inner side. Body narrow, 
elongate, parallel. 
The single species referred to this genus has very much the facies of a Scoloposcelis* ; 
but differs from it in the shape of the head and pronotum, the very slender third and 
fourth antennal joints, the punctured and pilose elytra, &c. From Lasiochilus it may 
‘be separated by the form of the orifice of the metastethium, the greatly incrassate 
anterior and posterior femora, the elongate, parallel shape, &c. 
1. Lasiochiloides denticulatus, n. sp. (Tab. XIX. fig. 3.) 
3. Elongate, narrow, shining, the elytra rather dull; clothed with a few erect hairs, the elytra thickly and 
shortly pilose, the margins of the embolium closely ciliate, the abdomen with several very long bristly 
hairs at the apex; piceous, the elytra with the sides below the shoulders broadly, and the transverse 
plica, ochreous (the ochreous coloration at the base extending down the embolium and covering the basal 
portion of the corium), the membrane fuscous; the head in front, the antenne, rostrum, and legs 
more or less testaceous, the femora infuscate. Head smooth, about as long as broad, the interocular space 
about three times the width of one of the eyes; antenne with joints 1 and 2 moderately stout, 3 and 4 
very slender, 1 reaching as far as the apex of the head, 2 three times as long as 1 and longer than 
3 or 4, the latter equal in length, 2 thickening outwards. Pronotum in front much wider than the head ; 
the anterior lobe smooth, and with an interrupted row of very minute punctures down the middle; the 
posterior lobe flattened on the disc and transversely rugulose. Scutellum rugulose at the apex. LElytra 
with the outer portion of the clavus, the corium, and cuneus sparsely, finely punctate, the clavus also 
with a row of punctures along the inner edge. Abdomen with a single long genital clasper on the left 
side only. 
Length 33 millim. 
Hab. Guatemata, Cerro Zunil 4000 feet (Champion). 
One specimen, from the Pacific slope. 
* The species of this genus usually have a hamus in the cell of the wings, but it is sometimes almost 
obsolete.
