AMERICAN COLEOPTERA. 137 



of the surface with intermixed pale-brown and whitish hairs. Body beneath 

 densely punctured, sparsely covered with cinereous hairs. Antennae rufous or 

 pale-brown. Length .20 — .22 inch; 5 — 5.5 mm. 



The specimeus before me are apparently all females. The antennal 

 club not lonpjer than the funicle, the first two joints nearly equal and 

 the terminal shorter than the other two united, oval and slightly 

 obliquely truncate on the inner side. 



Three specimens, San Diego, (Crotch), Oregon, (Horn). 



P. Belfragei, Lee, (Trogoderma), Trans. Am. Ent. Soc, lcS74, p. 49. 



This species is similar in ornamentation to the preceding, but of 

 more elongate form. Length .22 inch; 5.5 mm. 



Occurs in Texas. 



LUCANID.E. 

 L,UCANUS, Linn. 



Lucanus placidus Say., is thought by Major Parry to have been 

 described from the female of elaphus, and he would therefore place 

 the name lenlus Cast., to that form occurring in the Southern and 

 Western States to which the name placidus has been attached by 

 American Entomologists. A comparison of the descriptions of Say 

 and Castelnau, leave no doubt in my mind that both are applicable to 

 precisely the same species, and should the views of Major Parry be 

 adopted, our so-called j)lacidvs must be nameless. I cannot, however, 

 agree with this view, and have no doubt whatever that the descriptions 

 by Say and Castelnau, apply to the same species which is that now 

 known as pfacidus by us. This name should therefore remain. 



Platycerus coprulescens Lee, was previously described as oregonensis 

 Westwood. 



SCARAB^EID^. 

 Choer-idium Lecontei H.aTo\d, appears in the Check List as a synonym 

 of Imteroidcs. This is incorrect. The former has the hind thoracic 

 angles very much more broadly rounded and the margin at the angle 

 very feeble and not at all reflexed as in the latter. It occurs in the 

 Southern States. 



ONTHOPHAGUS, Latr. 



The species of Onthophngus are few in number in our fauna, and a 

 careful examination convinces me that the number already given in 

 our lists must be reduced, several having been described from varia- 

 tions in color and the degree of prothoracic development in the male. 

 The species divide themselves into two sections. 



Thorax of male protuberant in front, frequently with a long process more or 



less deeply emarginate at tip Section A. 



Thorax of male not differing from the female, both simply convex.. ..Section B.
