216 J. L. LECONTE, M. D. 



polished, sparsely, rather coarsely punctured with a wide dorsal smooth stripe. 

 Elytra polished, sparsely and coarsely but not deeply punctured. Abdomen 

 granulate, punctured. Gula narrowly but deeply channeled. Length 7 mm ; 

 .28 inch. 



Southern States; two specimens. This species differs from 0. latipes 

 not only by the larger size, but by the much finer and sparser punc- 

 tures of the head; and less numerous punctures of the prothorax and 

 elytra; the front part of the head is also flattened and obliquely de- 

 clivous, while in 0. latipes it is feebly but regularly convex. 



3. O. latipes, Er., Staph. 757; Oxytelus lat. Grav. Mon. 198; Oliv. Enc. 

 Meth., viii, 810; Molosoma lat. Say, Tr. Am. Phil. Soc. iv, 462 ; ed. Lee. ii, 677. 



Middle and Southern States, Kansas. Length 4 or 5 mm; .15 — 

 .20 inch. The smaller form was collected in Florida, by Messrs. 

 Hubbard and Schwarz, and very frequently has red elytra.

1. H. miuor, Fauvel, Ann. Ent. Soc. France, 1863, 437. 



Three specimens from Florida, (Hubbard and Schwarz), one from 

 South Carolina agree so closely with the description of this species 

 that I am not warranted in considering them as distinct. The front 

 tibiae are not absolutely free from spines, but with a high power a row 

 of fine distant slender spines may be seen, of which the largest is at 

 the outer apical angle. Length 2.75 mm ; .11 inch. 



Dr. Sharp* has shown very beautifully the relations between this 

 genus and Lispinus of the Piestini, from which it differs by the 

 prominent and contiguous front coxae. 



I observe in addition, that in all Piestini the submentum is much 

 larger and flatter, and defined behind by an angulated suture, while in 

 Osorius and IJolotrochus the transverse suture is nearly straight. By 

 this character, Ancseus is shown to belong to the Piestini, though the 

 front coxae are contiguous and a little prominent. The form of this 

 suture, however ceases to be even of generic value in Blediua, as will 

 be seen below. 



2. II. leevicauda, Lisjnnus luevic. Lee, New Spec. Col. 



Illinois, New Mexico, Louisiana. This species is very closely allied 

 to the preceding, but the elytra are nearly one-half longer than the 

 prothorax, less deeply punctured ; the dorsal segments are scarcely 

 perceptibly punctulate. The antennae are longer and less thickened 

 towards the tip.
