MAY, 1910. NOTES ON SOME CLERID^E WOLCOTT. 357 



Adelphoclerus nitidus sp. nov. 



Entirely black (except labial palpi which are pale yellow, the last 

 joint fuscous), shining. Head not wider than the thorax, sparsely 

 punctate; front longitudinally impressed at each side; pubescence 

 black and white, the white denser at the sides. Antennae shorter 

 than the head and thorax, distinctly clubbed. Thorax much nar- 

 rower than elytra at base, longer than broad, finely alutaceous, a 

 few, fine scattered punctures; pubescence black, at the sides yellow- 

 ish white and dense. Elytra strongly convex ; sides parallel ; pilose 

 with long, erect sparse black hairs and semirecumbent white hairs, 

 the latter more conspicuous towards the apex; punctures scarcely 

 visible. Length 6 millim. 



Jalapa, Mexico. Type in collection of the writer; cotype in the 

 cabinet of Prof. Wickham. 



Thanasimus monticola sp. nov. (PI. V, fig. 3.) 



Form of dubius Fab. and similar in color but differing as follows: 

 More shining ; head and thorax black, more sparsely and finely punc- 

 tate ; head densely clothed with long recumbent and erect gray hairs ; 

 thorax distinctly longer than broad, apical transverse impression 

 feeble; thorax and elytra rather densely clothed with long, erect, 

 black hairs. Elytra with the humeri only rufous; anterior fascia 

 more acutely and deeply angulate, the posterior fascia very narrow 

 at the sides but very broad at the suture; rows of coarse punctures 

 obsolete, except at basal fourth, where there are four feebly impressed 

 rows. Body beneath black; legs (except the knees), bright san- 

 guineous. Length 9 millim. 



This species resembles in color the variety rubriventris more 

 closely than it does the typical dubius, but the legs and humeri in 

 rubriventris are black and the rows of coarse elytral punctures long, 

 as they also are in the typical dubius, the outer rows extending beyond 

 the middle.
