THE CANADIAN ENTOMOLOGIST. 313 



This genus differs from Thiiiusa in its very long antennae, broad 

 hypomera, small eyes, and in many other characters. The type is the 

 following : 



B.Catalifue, w. ?,]). — Pale yellowish-brown in colour throughout the 

 body, legs and antennae, the abdomen feebly clouded with piceous from 

 rather before the middle nearly to the apex, extremely minutely and 

 closely punctulate throughout, the pubescence pale and rather con- 

 spicuous ; head rather large, flat or broadly impressed above, the antennae 

 half as long as the body, slender, just visibly incrassate distally, bristling 

 throughout with short and rather stiff erect pubescence, the tenth joint 

 distinctly longer than wide, the eleventh about as long as the preceding 

 two combined, gradually and acutely conoidal ; prothorax distinctly 

 wider than long, broadly, feebly concave toward the middle throughout 

 the length, except at the apical margin ; base superposed over the base of 

 the elytra, the latter flat, biobliquely truncate at tip, as wide as the 

 prothorax and four-fifths as long, the sides parallel ; abdomen strongly 

 margined, equal in width to the elytra. Length, 2.15 mm.; width, 

 0.43 mm. 



Catalina Island, California. 



A number of specimens were recently sent to me by Mr. C. F. Baker, 

 said to have been taken on the beach between high and low tide marks. 

 EuNONiA, n. gen. — Staphylinidpe. 



Body broad, subdepressed, small in size, the integuments polished, 

 very coarsely, rather sparsely sculptured, inconspicuously pubescent ; head 

 and prothorax much narrower than the hind body ; head wider than long, 

 the eyes convex, coarsely faceted, occupying the entire sides from near 

 the antenna to the basal constriction, vvhich extends entirely across the 

 very broad ba.se, the ocelli very small, basal, widely separated and 

 adjoining the constriction ; antennae well developed, nearly half as long 

 as the body, rather slender, bristling with long sparse setie, the three 

 outer joints enlarged, forming a loose club; mentum large; maxillary 

 palpi rather stout, the first joint small, second a little shorter than the 

 third, the latter stout, the fourth as long as the third, obliquely inserted, 

 conical, becoming aciculate at tip ; epistomal suture between the antennas 

 deeply excavated, except the oblique lateral parts before the supra- 

 antennal prominences, where it is fine ; prothorax wider than the head, 

 parallel and broadly rounded at the sides ; elytra large ; abdominal 

 border broad, strongly inclined ; legs rather short and slender ; coxse 

 rather small ; tarsi moderate, the first four joints very short, and together 

 longer than the last, the first shorter and more oblique than the second.
