cifir characters of which cannot be made clear until the sexual variations are 

 known. 



51. L. murina, nigra, distinctius punctata, parciiis cinereo-pubescens, tho- 

 race convexiusculo, cannpanulato, subcanaliculato, latitudine non longiore, palpis 

 antennisque nigris, his articuloSndo lony:iore. Long. -4 '45. 



Lake Superior ; two males. Easily distinguished by its more sparse pubes- 

 cence ; the thorax is shorter, more convex, and more narrowed anteriorly, and 

 the upper surface is more distinctly punctured ; the antennae are half the length 

 of the body, the first joint reaching the occiput, the second joint equal to the 

 two following. With this species I doubtfally associate a female from Mis- 

 souri Territory, agreeing in form and punctuation, in which the antennae are a 

 little stouter than in C. Fabricii, with the second joint about o-ne-third 

 longer than the third. 



52. C. d eb i 1 i s, valde elongata, atra, punctulata, cinereo-pubescens, thorace 

 subcampanulato, latitudine longiore, canaliculato, basi profunde foveato, palpis 

 antennisque nigris, his (ferainae) tenuibus, articulo 2ndo 3io longiore. Long. 'So. 



Two females; New York. This species resembles closely C. Fabricii, but 

 the thorax is less rounded in front, aud the dorsal channel is deeply transversely 

 excavated at the base ; the antennae are half the length of the body and formed 

 exactly as in C. Fabricii. The pubescence is less dense than in C. Fabricii, 

 but more dense than in the last species. 



The following species are unknown to me : 



53. Cantharis lineata Olivier, Ins. 46, 14, tab. 2, fig.21 , (apparently 

 resembles C. Germari). 



5i. Lytta Afzeliana Fabr. Syst. El. 2, 78. (ISOl). 

 Cantharis sinuata Oliv. Ins. 46, 9, tab. 2, fig. 14. (1795).

 1,3. A fragment in Dr. Melsheimer's Collection, belongs to L. filiformis Lec^ 

 but the disc of the thorax is destroyed, and in other respects it does not agree 

 with Say's description.

58. Lytta sanguinicollis, atra, pubescens, capite thoraceque laete 

 rufis, elytris nigris sutura margine vittaque angusta einereis. Long. -27. 



Georgia ; rare. The description is made from a drawing. It is the Epicauta 

 sanguinicollis of Dejean's Catalogue.

Apalus qnadrimaculatus Fabr. Ent. Syst. 2, 50 ; Syst. EI. 2, 25. 

 Southern States; rare. The male is distinguished by having the anterior tarsi 

 dilated, and the first joint prolonged internally. 



2. T. fulva, fulva, nitidiuscula, longius pubescens, minus confertim punc-

New Mexico; collected by Fendler. This species is similar to T. frontalis 

 Chevr. (Col. Mexique,) but is much smaller; the head is entirely fulvous, and 

 the feet are not black; the pubescence is less dense, and the punctures of the
