Dec, 1916.] New Species of Elaterid^. 261 



Otto Schwarz in Genera Insectorum erects for our species of 

 Ludius which have the intercoxal process of prosternum not suddenly 

 and perpendicularly declivous a little behind the coxae, the genus 

 Trichophorus using Liidius Eschsch. for Corymbites Latr. Following 

 strictly the law of priority he may have been correct, but I do not 

 agree with him in placing our Megapcnthes tartarens, aterrinius, 

 Umhalis and Elater sturmii also in the genus Trichophorus. 



For those species having the intercoxal process of prosternum a 

 little behind the coxae suddenly and perpendicularly declivous he 

 erected the genus Diplostethiis and for the species having a parallel 

 sided mesosternal fossa the genus Parallclostcthus. Our Liidius at- 

 tenuatus and five Asiatic species are referred to this latter genus. 



Trichophorus carolinensis new species. 



Very close to texanus from which it differs in narrower, more elongate 

 form, slightly longer antennae, prothorax more gradually narrowing to apex, 

 generally more opaque surface and pubescence slightly erect. Length iS mm. 

 Width 5 mm. 



Southern Pines, N. Carolina (A. H. Mance). 



This species is apparently what Leconte, Horn and Candeze con- 

 sidered to be hepaticiis a species which, according to Champion, dif- 

 fers generically from the North American species identified by Le- 

 conte, etc., as that species. The true hepaticus is placed by O. 

 Schwartz in Genera Insectorum in the genus OrthostctJius and only 

 recorded from Brazil. 



Besides the locality given above I have some specimens from 

 Roanoke Isld. and Wilmington, N. C. (Engelhardt & Pollard), from 

 S. Carolina and two smaller specimens from Florida. 



Trichophorus substriatus new species. 



Elongate, rufo-castaneous ; underside antennae and legs scarcely paler. 

 Head moderately coarsely and densely punctate ; antennaeae reaching to the 

 hind angles of prothorax, third joint a little longer than second, both together 

 slightly shorter than fourth. Prothorax about as long as wide at base; hind 

 angles acutely carinate ; sides rather feebly converging to about apical fifth, 

 thence feebly arcuate ; surface moderately closely punctate. Elytra a little 

 longer than twice as long as the prothorax at base, rather strongly narrowing 

 to apex; punctate striate, the fiist two or three near sutural striae obliterated, 

 intervals flat and very closely punctate. Under side clothed sparsely with 

 short, yellowish recumbent pubescence ; prothorax beneath rather coarsely
