size, there is not in the smaller examples any tendency towards that obsolescence of 
the striz which is characteristic of P. maurus. 
EPOMADIUS, gen. nov. 
Caput subrostratum ; antennarum funiculus sat longus, articulis 3°-6™ transversis, latitudine crescentibus, clava 
ovata. Prothorax elytris angustior, basi submarginatus, anterius supra subasperatus ; carina lateralis 
utraque obsolescens et plaga magna depressa pube densa vestita antice terminata. Coxe anticw et 
intermedi sat late distantes. Tibie lineares supra spinulis 2 aut 3 serrate ; tarsi breves, articulo 1° 
sequenti breviore, 2° et 3° lateraliter compressis. 
Head subrostrate ; antenne moderately long, joints 3-6 of the funiculus distinctly transverse, the club oval, 
with two slightly curved sutures. Prothorax not margined at the base, the lateral margins almost 
obsolete and replaced on the anterior half of the sides by a large shallow depression, covered with short 
curled hairs. Elytra much wider than the prothorax. Anterior and middle coxe moderately remote. 
Tibize linear, the anterior pair with the superior border simple, and with one or two backwardly directed 
spines above, and one beneath the tarsal articulation ; superior border of the middle and posterior tibice 
rounded at apex, with three or four spines. First tarsal joint short, the second and third laterally 
compressed. Abdominal segments 2, 3, 4 nearly equal. 
The genus is constructed for one singular-looking species, remarkable for the pilose 
impression at each side of the prothorax. The anterior tibiz appear in certain aspects 
to be entirely unarmed, and the exact relation of the two or three short spines to the 
articular cavity and apex of the tibia is extremely hard to make out. 
1. Epomadius culcitatus, sp.n. (Tab. VII. fig. 4.) 
Oblongus, subnitidus, ferrugineus, capite nigricante, pube tenui flava appressa pilosus; prothoracis lateribus 
utrinque plaga impressa flavo-pilosa ornatis, dorso antice granulis posterius rarioribus instructo, postice 
punctato ; elytris striato-punctatis, interstitiis planis confuse punctatis. 
Long. 2°5 millim. 
Oblong, slightly shining, ferruginous-brown, with thin short decumbent yellowish pubescence. Head blackish, 
front subconvex, subglabrous, shining, finely and sparingly punctured, with a median subelevated line 
towards the vertex, epistoma produced over the mandibles ; antennz testaceous-brown, the club infuscate, 
shining, the apical joint and sutures pubescent, the basal suture transverse, the second curved. Prothorax 
as long as wide, subtruncate at base, the hind margin shining but not elevated, the posterior angles 
oblique, margined, the sides posteriorly straight, with a nearly obsolete lateral margin which divides 
about the middle, to enclose a large shallow impression towards the front of each flank, set with thick, 
short, upstanding, curved yellow hairs, apex broadly rounded ; disc moderately convex, obliquely declivous 
from the middle to the apex, thinly pubescent, set with small granulations, closer and stronger in front, 
becoming more remote and feeble behind the middle and replaced by punctures towards the base, median 
line shining, elevated from the base to the middle. Scutellum small, rounded. Elytra wider than the 
prothorax and more than one-half longer, exactly truncate at base, the shoulders rectangular, the sides 
straight and subdivergent, incurved obliquely behind the middle and converging to the apex, which is 
more obtuse in the middle ; surface subcylindrical at the base, obliquely and convexly declivous behind, 
flatter along the suture than at the sides, with thin short decumbent pubescence, finely striate-punctate, 
the striz scarcely impressed, the sutural stria not deeper, interstices multipunctate, the punctures not 
weaker than those of the strie. Underside brown with fine pubescence.
