strongly convex, slightly separated. Middle coxae with small trochanters; 

 posteiior transverse, separated by a triangular process of the first ventral 

 segment. Tibias scarcely dilated; spurs small but distinct, unequal; tarsi 

 moderate, setose beneath, the posterior more densely so at base; last joint 

 slightly longer than the preceding together; first four joints of the anterior 

 and middle very short equal; nrst of the posterior as long as the next two com- 

 bined. Elytral hypomera continuous throughout the length, rather narrow, 

 strongly inflexed, nearly equal in width throughout, slightly concave near 

 the base, elsewhere plane. Prothorax transverse; sides of the pronotum very 

 abruptly and narrowly explanate or feebly reflexed; edges neither denticulate 

 nor crenulate. Elytra finely costate; intervals punctate. 



The affinities of this genus are very readily seen to be in 

 the direction of Bolitophagus and Eledona; it agrees with 

 the first in the structure of the front and eyes, but differs 

 in appearance, in this respect agreeing more closely with 

 Eledona, from which, in turn, it differs radically in the 

 structure of the eyes. In Eleates the epistoma is separated 

 from the labrum by a very short, coriaceous bond, as is usual 

 in this group, but the eyes are well in advance of the pro- 

 thorax. It differs from both Bolitophagus and Eledona in 

 the non-denticulate sides of the prothorax, a character con- 

 sidered more or less important by Lacordaire and Du Val, 

 who divide the European genera into groups depending 

 upon the presence or absence of denticulations. 



E. OCCidentalis a- sp. — Rather robust; sides nearly straight and parallel; 

 black throughout; legs, palpi and antennas dark rufo-fuscous; glabrous; in- 

 teguments rather finely sculptured. Head nearly twice as wide as long; apex 

 very narrowly reflexed throughout; surface near the apex and in front of the 

 eyes slightly tumid; front broadly and feebly convex, extremely densely, 

 rather deeply and coarsely punctate; punctures very much finer and obsolete 

 on the epistoma. Prothorax widest near the base, where it is two-thirds wider 

 th m the head and twice as wide as long ; sides feebly convergent from base to 

 apex, feebly arcuate; base broadly arcuate, more strongly so in the middle; 

 angles slightly obtuse, not rounded; apex slightly narrower than the base, 

 broadly and rather strongly emarginate; angles slightly prominent, anteriorly 

 narrowly rounded; disk broadly, strongly and very evenly convex, rather 

 coarsely, evenly, deeply and excessively densely punctate; punctures poly- 

 gonal, intervals in the form of very narrow, strongly elevated lines. Scutellum 

 broader than long, rounded behind. Elytra at base slightly wider than the 

 prothoiax; sides ueaily parallel and straight to within a very short distance 

 of the apex, where, together, they are abruptly and very broadly rounded;
