A large, characteristic and easily identified genus with a rather 

 cylindric, densely chitinized, more or less slender body of a black or 

 grayish-black, often feebly lead-glistening color, ordinarily with ro- 

 bust or dense punctation, most often with short and very fine, whitish- 

 gray hair. — (Page 481) The head (Fig. 



144) is broad, as a rule broader than pronotum, with remarkable, very 

 large, strongly protruding, convex eyes, which entirely occupies the 

 sides of the head; constricted behind the eyes, forming a short and broad 

 neck, most often bearing between the eyes two more or less distinctive 

 longitudinal grooves, separated by a stronger or feebler convex inter- 

 val. Antennae are fine, not long, inserted free on the forehead between 

 the eyes, their first two joints more robust than the middle ones, the 

 third elongated, longer than the others, the last three thickened, to- 

 gether forming a feeble club. The mandibles are covered by the prominent, 

 entirely chitinized and undivided labrum; the second and third joint of 

 maxillary palpi are elongate, the first half as long as the second, the 

 third long and slender clavate, the fourth extremely small, scarcely 

 visible in tip of the third. • — F*- : -144. Stenus Juno Fabr. p .
