NATURAL SCIENCES OF PHILADELPHIA. 71 



One specimen, Tejon. In this the most remarkable, as well as the largest 

 species of the genus, the front is slightly concave, with a raised margin, and 

 the tibia? are suddenly dilated and denticulate as in the others. The sides 

 of the thorax are parallel from the base nearly to the apex, where they are 

 suddenly obtusely angulated, and run to the anterior angles which are round 

 ed : the incision near the base cuts across the incrassated side, leaving the 

 posterior part a small quadrate elevated plate, the anterior portion larger, sub- 

 triangular with truncate angles, flat, opaque and densely pubescent. 



29. Saprinus lug ens. 30. S. o regon ensis . 31. S. lubrieus. 



32. Brontes truncatus. 



33. Dermestes marmoratus. 34. D. Mannerhe i mi i . 



35. Attagenus rufipennis, elongatus, niger, pubescens, thorace latitii- 

 dine duplobreviore, paulo convexo, confertim minus subtiliter punctato, elytris 

 parcius punctatis, rufo-testaceis, tarsis rufo-piceis. Long. -12. 



One female, Tejon. A small species, differing from the others in my collec- 

 tion by the more coarse and dense punctuation of the thorax : the head is 

 punctured like the thorax and the antennae are entirely black. 



36. Anthrenus 1 e p i d u s . 



37. Serica fimbriata. 



38. Hoplia callipyge. This may be a favorable opportunity to observe 

 that recent observation has shown that H. tristis Mels. is the male of H. 

 trifasciata Say (primoria Burin.), a fact that could never have been infer- 

 red from the appearance of the two supposed species. 



39. Pleocoma fimbriata. Some fragments of this insect, found in the 

 stomach of a woodpecker at Tejon, enable me to investigate the oral organs. 



The clypeus at its inferior margin is emarginate for the insertion of a 

 pyramidal hairy corneous labrum : the mandibles are short, pyramidal acute, 

 with a few hairs near the apex. The maxillae are large at the base, with the 

 lobes very small, the outer one not reaching beyond the first joint of the palpi, 

 penicillate with long hair, the inner one much smaller, narrow and pointed ; 

 palpi slender, first joint short, 2d long, 3d one-half shorter than 2d, 4th a 

 little longer than 3d. Mentum broadly rounded in front ; ligula almost semi- 

 circular, palpi inserted on the upper face of the ligula, bases contiguous, with 

 intermediate pencil of hairs, 3d joint longer than 2d, and the latter longer than 

 the first. It will thus be seen that combined with the 11-jointed antenna? 

 with polyphyllous club, the characters above detailed are abundantly sufficient 

 to establish this genus as a new group, related to Geotrupida? and Copridse, 

 wrth, however, strong tendency towards the Dynastide group of Scarab. 

 pleurostioti. 



40. Canthon simplex. 



41. Anthaxia strigata, lata depressa, nigro-amea, ssepe cyaneo-variegata, 

 thorace latitudine fere duplo breviore, lateribus rotundatis, angulis posticis 

 subrectis, fortius reticulatim punctato, utrinque pone medium oblique im- 

 press, elytris thorace hand latioribus, confertim fortius granulatis, fortius 

 marginatis, parallelis, postice suboblique attenuatis et rotundatis. Long. 

 17 -25. 



Tejon, abundant. Front moderately concave, hairy : the sides of the thorax 

 are less rounded than in A. expansa, the punctures are strongly marked, 

 and there are besides fine elevated lines, having a general longitudinal direc- 

 tion, connected together forming elongate meshes. In some specimens the disc 

 of the thorax is darker than the sides. It is, perhaps, A. ten e ogas t e r Lap. 

 and Gory ; the description given by them contains no definite character by 

 which to separate it from allied species.
