May, 1910. Notes on Some Clerid.« — Wolcott. 347 



been questioned, nor has it ever been verified; in what manner the 

 decision regarding the identity of the species was reached by Dr. 

 Horn is not known, but it seems very probable that wrongly deter- 

 mined Mexican material may have been responsible for the state- 

 ment. Be that as it may, the fact remains that the description of 

 cylindricollis fails to agree with the description and specimens of 

 Msta in several very important characters. 



Cylindricollis is described by Chevrolat as ha\nng the ''Corse- 

 let trois fois plus long que large, .... Elytres . . avec- 

 neuf stries chacune Les antennes sont de la longueur d'une 

 ^lytre. k articles allonges et de meme grosseur; le dernier allong^. 

 termine en pointe." (Col. Mex., cent, i, fasc. i, 1833.) 



In usta the prothorax is but one-third longer than wide; the 

 elytra are each lo-striate and the antenna:* have the second and third 

 joints obconical. equal and short, together being but little longer than 

 the fourth joint. 



It being clearly impossible to reconcile the many discrepancies 

 between these two species, usta should be removed from the 

 synonymy. 



Cymatodera torosa sp. nt)v. 



Robust, dark brown; antennae, palpi, legs, and abdomen brownish 

 testaceous; moderately clothed with rather short pale pubescence. 

 Head very coarsely, densely punctate; eyes prominent. Antennae 

 slightly longer than head and thorax; joints two and three short, 

 conical, equal, together shorter than joint four; joints four, five, and 

 six strongly serrate; joints four to ten subequal in length but grad- 

 ually narrower toward apex; eleventh joint one-third longer than 

 tenth. Thorax nearly twice as long as wide at apex; base slightly 

 narrower than apex; sides before the middle feebly constricted; 

 behind the middle moderately compressed; ante-scutellar impression 

 feeble; disk rather coarsely and densely punctate. Scutellum sub- 

 cordate, feebly emarginate at base. Elytra twice as wide at base as 

 thorax; humeral angles obtusely rounded; sides nearly parallel; 

 disk convex, each with ten rows of coarse quadrate punctures be- 

 coming slightly smaller posteriorly and extending nearly to apex; 

 the extreme apex rather roughly sculptured ; punctures of first lateral 

 stria scarcely extending to the middle; intervals rather convex, 

 equally as \v'ide as the punctures, finely irregularly punctate. Pro- 

 meso- and metastemum finely and rather sparsely punctate; abdo- 

 men very finely and densely punctate. Length 9.5 millim.
