AMERICAN COLEOPTERA. 2 ^ 



H. texanus, Shp., is what we have called atripennis, Say, which name 

 \ Sharp assigns to a Bra 

 On the whole I am inch 

 all these forms one species. 



Dr. Sharp assigns to a Brazilian species. 



On the whole I am inclined to agree with Mr. Crotch, who considered 



I^ACCOPHIIiUS. 



L.fusculus, Shp., founded on one female specimen, does not appear 

 separable from decipiens, Lee. 



L pictus, Cast, occurs in Arizona and the Peninsula of California 



L insignis Shp.— This and the preceding species were confounded 

 together by Crotch. It occurs in Texas only, as far as we know. This 

 species has the yellow marks on the elytra forming distinct fasciae, while 

 in pictus the yellow marks are in the form of small isolated spots. An- 

 other species closely allied to these two has been collected in Arizona 



L americanus, Aube, is noted in our fauna by Dr. Sharp. I have 

 never seen native specimens, but it is known to me from the Antilles 



L terminal-is, Shp.-Closely allied to fasciatus, Say, and recalling 

 also maculosus. It is known to me from Peninsula of California and the 

 adjacent regions of Upper California. 



L. atristerna/is, Crotch, is mexicanus, Aube. 



COELAMBUS. 



C. fumatus, Shp, seems to be the true lutescens, Lee. The latter, as 

 determined by Dr. Sharp, should receive another name. 



m/uscatus, Shp.-A specimen from Oregon referred by me to this 

 species is a male. The anterior tarsal claws are dissimilar, the anterior 

 being a little shorter than the posterior, stouter, more arcuate and rather 

 broadly dilated at base. 



DEBOMECTES. 

 D suffusm, Shp.-Specimens from Massachusetts in my cabinet be- 

 long to this species, but I am unable to convince myself that it is specifi- 

 cally distinct from catascopium, Say. 



D prostemalis, Shp.-This is clearly Say's catascopium. I do not 

 know why the latter name should be disregarded. It is distinguished 

 from o-riseostriatus by having the presternum more cannate in front, but 

 IainVte sure from my observation that this is an evanescent char- 



acter. 



HYDROPORUS. 



//. pulcher, fide Slip, is not pulcher. Lee, which lias no distinct 



sutural stria. 



//. integer, Shp, is the true pulcher, Lee.
