OF WASHINGTON. 79 



3-jointed; prosternum well developed before the coxae, without median 

 carina; body elongate, cylindrical, glabrous; anterior tibiae thickened, 

 externally rounded and spinulose at apex ; secondary male characters 

 usually pronounced, affecting both the epistoma (clypeus of Casey), 

 angles of front, and apex of prothorax, varying in degree within the 

 species according as the male is more or less well developed, the de- 

 pauperate forms scarcely differing from the females, except that the 

 first ventral segment of abdomen is marked medially near its posterior 

 margin with a small, deep, pubescent fovea. 



Ennearthron transversatum, n. sp. (Plate III, fig. 7). 



Female. Elongate, glabrous, polished, nigropiceous to black, pro- 

 thorax wholly dark colored, except that the anterior margin is slightly 

 lighter, the elytra entirely black or nigropiceous except for two large, 

 elongate, brownish-yellow spots half way between the base and vertex 

 and more or less confluent at the suture, forming an irregular trans- 

 verse band not attaining the margin. Abdomen pale rufous, legs amber. 

 Head fuscous, the vertex piceous; front convex, with numerous fine, 

 deep, regular punctures ; epistoma opaque, feebly punctured, narrowly 

 semielliptical, anterior margin truncate, entire, slightly produced be- 

 yond the produced frontal angles which proceed each side to the 

 eyes as a strongly curved elevation. Prothorax broader than long, the 

 sides strongly curved, base slightly rounded posteriorly, anterior margin 

 rounded, somewhat prolonged over the head; punctures dense, coarse, 

 deep, irregularly arranged, producing a decided roughened appearance. 

 Elytra slightly more than twice the length of the prothorax and not 

 quite twice as long as wide, sides broadly rounded, declivity very 

 steep and convex, apex broadly abruptly rounded ; punctures very dense, 

 deep, irregularly arranged, not smaller than those of prothorax. Length, 

 1.2 mm.; width, 0.4 mm. 



Male. Similar to female in coloration, except that the yellow spots 

 of the elytra are slightly more distinct; head and prothorax not modi- 

 fied, first ventral segment of abdomen with a subcircular, densely 

 pubescent spot at the middle towards posterior margin. Length, 1.2 

 mm. ; width, 0.45 mm.
