Nor til American Species of Trogophlmus, 353 



minutely and sparsely punctate. Legs ^moderately slender. Length 

 1.5 mm, 



Khode Island (Newport 8). 



A very distinct species, not liable to be confounded with any 

 other. It was taken by the author in considerable abundance in 

 the short moss, covering the salt marsh behind the ocean beach, 

 in April. It is not gregarious and its motions are very slow.

The two specimens before me were taken by the writer in 

 Marin Co., California; they agree in every particular With the 

 Le Contean type. As the species is very distinct and not liable 

 to be confounded with any other known to us, the original de- 

 scription will amply serve for its identification.

 tennae throughout and palpi black; legs piceous-black, knees and tarsi 

 very slightly paler; pubescence very fine, short, and sparse; integuments 

 strongly shining. Head just visibly narrower than the prothorax, rather 

 convex, densely and somewhat coarsely and deeply punctate; promi- 

 nences rather large and distinct; antennae robust, not quite as long as the 

 head and prothorax, rather strongly clavate; second joint more robust 

 and slightly longer than the third, fourth very small, scarcely as long as 

 wide, tenth distinctly wider than long, obconical, ninth abruptly much 

 wider than the eighth; eyes moderate, very slightly prominent, rather 

 finely granulate; tempora nearly as long as the eye, strongly rounded

 but slightly more than one-third wider than long; sides very broadly 

 rounded anteriorly, convergent and straight in the basal half; basal 

 angles slightly rounded; apical broadly obtuse, not rounded; base feebly 

 arcuate, three-fourths as wide as the disk, much narrower than the 

 apex; disk rather finely, sparsely punctate in the middle, punctures 

 twice as wide, variolate and just visibly separated toward the sides, 

 where the surface is also broadly impressed in the middle; median lon- 

 gitudinal impressions very distinct. Elytra quadrate, one-third wider 

 and nearly two-thirds longer than the prothorax, feebly impressed near 

 the suture, coarsely and deeply punctate, the punctures separated by 

 distinctly more than their own diameters. Abdomen slightly narrower 

 than the elytra and wider than the prothorax, parallel; sides feebly ar- 

 cuate; border moderate; surface feebly convex, feebly reticulate,
