NOSiODKNDRON, Latr. 

 JK, caliCbriiirum, n. sp. — Form broadly oval, moderately convex, bhick, 

 feebly shining. Head moderately coarsely and closely punctured. Thorax 

 less densely punctured than the head or elytra and more shining, sides very 

 feebly arcuate Elytra subopaque, coarsely, densely and rather deeply punc- 

 tured, punctures at sides denser but smaller, and with small, round tufts of 

 short, erect yellowish scale-like hairs arranged in fine series on each elytron 

 I those on the dorsum usually lost). Body beneath opaque. Mesosternum very 

 coarsely punctured, abdomen more finely and sparsely punctured. Length .18 

 inch ; 4.& mm. 



This species is of the same form and size of our Eastern species, 

 fimiu which it diflFers by its more opaque and closely punctured sur- 

 face and the possession of the elytral tufts. In the latter character it 

 resembles the transatlantic species, y«scicM/ore, with which I have been 

 uuable to compare it. 



One specimen from California, kindly given me by Mr. Ulke; 

 others were collected by Mr. Crotch, at Calaveras, in the same State. 



EiiTHESOPrS, Escb. 

 E. bicolor, n. sp. — Oblong, rufo-piceous, thorax and head mfous, elytra 

 black, legs testaceous. Head sparsely punctured. Thorax slightly longer than 

 wide, in front feebly arcuate, at base slightly broader, surface shining, sparsely 

 punctured. Elytra deeply striate, strise coarsely and deeply punctured, inter- 

 vals convex, irregularly biseriately punctulate and obsoletely reticulate. Body 

 beneath sparsely and finely punctured. Antennse and palpi testaceous. Claws 

 broadly toothed at base. Length .22 inch; 5.5 mm. 



The surface is very sparsely pubescent. The thoracic punctures 

 are those of the coarser series, the finer intermediate punctures being 

 scarcely visible. Differs from our other species by its color. 



One specimen presented by Mr. Edw. Tatnall, Jr., by whom it was 

 collected in Delaware. 



Oardii'phorus mimeticus, Horn, (Trans. Am. Ent. Soc, 187*ii, p. 

 147,) appears to be merely a male of C Edwardsii, Horn. The 

 former species has the humeri only red, while in the latter the exten- 

 sion of that color embraces the entire elytra, except an elongate, fusi- 

 form, sutural black stripe. The former name should be suppressed. 

 The determination is founded on a moderate series brought by Mr. 

 Crotch, 



EL.ATER, Linn. 

 E. Phelp«*ii« n. sp. — Form of cordifer, slightly more elongate and convex. 

 Head black, densely punctured and opaque, sparsely clothed with short, black, 

 erect hairs. Antennee not longer than head and thorax, joint 3 slightly longer 

 than 2, and together not longer than 4, outer joints triangular. Thorax not 

 longer than wide, sides in front feebly arcuate, hind angles not divergent au4
