126 Memoirs on the Coleoptera 



the elytra have fine smooth striae and more than three small dorsal 

 punctures; the met-episterna are moderately elongate, the tarsi 

 long and very slender, with the lateral sulci narrow. Lastly, but 

 most important of all as a distinguishing character, the pubescence 

 of the antennae begins on the third joint, which is longer than the 

 fourth; this joint is completely glabrous in all the preceding types 

 of the subfamily. The genus seems to be widely distributed 

 throughout the northern hemisphere and is well represented in the 

 European fauna. Our species, so far as known to me at present, 

 are as follows: 



Sides of the prothorax at base only very feebly and narrowly reflexed. . . 2 



Sides at base more strongly reflexed. . , 5 



2 — Eyes very prominent, the tempora behind them long. Body rather 

 slender and only feebly convex, moderately shining, pale reddish- 

 brown, the head black; under surface piceo-rufous, the legs and 

 epipleura flavate; head elongate-rhomboidal, rather longer than 

 the prothorax and four-fifths as wide; impressions broad and 

 shallow; antennae slender, three-fifths as long as the body, slightly 

 fuscous, but paler testaceous basally; prothorax slightly elongate, 

 parallel, with broadly and subevenly arcuate, finely reflexed sides, 

 though widest before the middle; angles very broadly rounded; 

 surface with some feeble transverse rugulae, the anterior impression 

 evident and the stria subentire; foveae smooth, moderate, linear, 

 broadly and very feebly impressed; sides slightly more reflexed 

 basally though well separated from the foveae; elytra nearly three- 

 fifths longer than wide, fully twice as wide as the prothorax, parallel, 

 the sides rapidly rounding at base; apex gradually rounding, the 

 sinus short, distinct; striae fine but sharp and deep, smooth; inter- 

 vals not quite flat internally, the third with four moderate punc- 

 tures, the first two near the third, the others near the second, stria; 

 anterior male tarsi very moderately dilated. Length (cf) 6.8 mm.; 

 width 2.3 mm. Texas (Galveston). A single example, taken by 



the writer galvestonicus n. sp. 



Eyes not or but slightly prominent, the tempora shorter; head relatively 



narrower as a rule 3 



3 — Body black, more convex, the elytra generally obscurely piceous, 

 the legs piceo-rufous. Head slightly elongate and three-fourths as 

 wide as the prothorax, the impressions narrower and deeper than 

 in the preceding, the antennae very slender, black, with the basal 

 joint picescent, more than half as long as the body; prothorax about 

 as long as wide and widest before the middle, the sides anteriorly 

 strongly rounded, straighter and more oblique posteriorly, very 

 finely reflexed throughout, with the angles broadly rounded; surface 

 smooth, moderately and very evenly convex, the two impressions 

 obsolescent, the fine stria feebly impressed; base nearly as wide as 

 the moderately sinuate apex; foveae narrow and linear but extremely
