372 Coleopterological Notices, VII. 



wide, almost evenly parabolic behind the eyes, which are anterior and rather 

 small but convex and somewhat prominent; clypeus nearly as in occultus; 

 labrum large, sinuate at the middle of the apical margin. A ntennse stout, 

 barely longer than the head and prothorax, the club strong and very abruptly 

 formed, almost parallel; joints proportioned nearly as in occultus, the seventh 

 not as long as wide and the two penultimate more strongly transverse; seventh 

 joint but very slightly wider than the sixth; eighth fully ^ wider than the 

 seventh. Prothorax fully as long as wide, nearly }^ wider than the head? 

 formed nearly as in occultus; surface bifoveate near the base at each side, but 

 scarcely at all impressed, the outer fovea the smaller and continued obliquely 

 in a narrow excavation to the basal margin between two minute carinse. 

 Elytra % longer than wide, distinctly more than twice as long as the prothorax 

 and nearly ,*- wider, widest before the middle, the sides evenly arcuate 

 throughout; apex narrowly parabolic; humeral plica and impression rather 

 long but extremely feeble; fovege deep and approximate; suture minutely 

 beaded subbasally, the bead rapidly expanded into a large but feeble tri- 

 angular plate at the basal margin; on and involving the suture there is a large 

 and deep concavity of elongate-oval form, occupying nearly basal third of the 

 length. Legs well developed, the two anterior femora strongly, the four pos- 

 terior moderately, clavate; hind tarsi with the first four joints subequal, the 

 first two exactly equal. Length 1.6 mm. ; width 0.63 mm.

This is one of the most interesting species of the genus and is 

 probably myrmecophilous. The description applies to the female, 

 the male antennae being nearly half as long as the body, the 

 second joint much longer than the next two, three to seven no- 

 ticeably longer than wide, the club abrupt and parallel as in the 

 female but a little more elongate ; the hind trochanters are trun- 

 cate at tip, but there are no abdominal modifications. The elytra 

 are more elongate, the humeral plica more distinct and the sutural 

 indentation rather more feeble in the male. 



This species is allied closely to occultus but is slightl}^ stouter, 

 and may be readily distinguished by the indented elytral suture ; 

 the erect setae of the el3^tra are much less conspicuous. 



7. E. occultus n. sp. — Somewhat narrow and feebly ventricose, polished, 

 the elytra minutely, sparsely and feebly punctulate, pale rufo -testaceous 

 throughout, the legs and antennae concolorous ; pubescence pale, stiff and 

 rather abundant on the elytra, where it is intermingled with much longer 

 sparse and erect setae, the hairs rather short and recurved, coarse on the flanks, 

 finer and shorter toward the suture, toward which they are obliquely directed 

 behind the middle, abundant, short, coarse and stiff on the head and prouo- 

 tum. Head wider than long, broadly rounded at base, the sides subparallel 

 and rounded behind the eyes, which are small but convex and prominent ; 

 antennal prominences convex and distinct ; clypeus transversely truncate.
