CROSSID1US Lee. 



The species of this genus with tuberculate sides of the prothorax 

 may be easily distinguished as follows : — 



Prothorax more or less strongly transverse, very densely, confluently punc- 

 tured and densely pilose. 

 Antennae of the male rather short, never much longer than the hody, those 

 of the female very short and stout, with the joints scarcely more than 

 twice as long as wide. 

 Elytral punctuation very coarse, becoming slightly finer toward apex, the 



punctures always distinctly separated punctatllS 



Elytral punctuation finer, becoming extremely dense toward apex. 



testacens 

 Antennae of the male very long and slender, much longer than the body, 

 those of the female moderate in length, slender, with the joints three 

 or four times as long as wide. 

 Antennae and legs pale ; posterior tarsi short and slender ; elytral punc- 

 tures coarse, always distinctly separated intermedins 



Antennas and legs black or piceous-black ; posterior tarsi longer and 

 much stouter. 

 Elytral punctures fine and very dense, coarser toward base. 



longipennis 

 Elytral punctures very coarse, nearly as in punctatus, hut much denser. 



crassipes 

 Prothorax much less transverse, coarsely, deeply punctate and shining, the 

 punctures all distinctly separated. 

 Antennae of the male much longer than the body. 



Elytra rather finely and very densely punctate, the elytral base and 



suture throughout black hirtipes 



Elytra very coarsely, sparsely punctate, with a narrow fusiform black 

 area at the suture, scarcely ever extending as far as basal fourth. 



nitidicollis 



Antennae of the male much shorter, never notably longer than the body ; 



elytral punctures very coarse toward base, the disk with a broad black 



sutural area, which is usually angulate anteriorly, sometimes attaining 



the base pulchellus 



The posterior legs are notably longer than the four anterior 

 throughout the genus, as usual in this part of the family. 



C. longipennis n. sp. — Elongate and slender, the female more robust, 

 oblong and parallel, pale brownish-testaceous throughout, the legs, antennae, 

 a more or less narrow fusiform sutural line not closely approaching the base, 

 and the pronotum except laterally, black ; integuments moderately shining ; 

 pubescence fine, long and very dense on the pronotum, shorter but dense on 

 the elytra. Head rather small ; antennae (male) nearly one-half longer than
