11. L. Burnieisteri, longior, cylindrica, rufo-testacea nitida, capite obscuriore, sat dense punctato,

Trichestes longitarsis% Burm. Lamell. 2, 2d, 359. 



One male found at New York. This species bears no resemblance to Say's Melo- 

 lontha longitarsis, but is very closely allied to the preceding, from which it differs 

 chiefly by the clypeus being sparsely punctured and more deeply emarginate, and by 

 the body being more slender. 



The male has the club of the antennse shorter than the stem ; and the abdomen and 

 posterior tibiae precisely as in the preceding species.

Ancylonycha glaherrirna Blancb. Cat. Col. Mus. Paris, 136. 



Georgia. This species has precisely the form of the preceding, but the head is 

 more coarsely and less densely punctured. 



The male has the club of the antennse longer than the stem ; the abdomen faintly 

 channeled, the penultimate segment faintly impressed and roughened at the middle, 

 with the posterior margin not emarginate as in the two preceding, with a very 

 slight oblique discoidal elevation each side towards the middle ; last segment with a 

 very deep round fovea, bounded each side by an elevated ridge, which, however, 

 hardly rises into a cusp, as in L. c e r a s i n a . Posterior tibiae with the terminal 

 fringe of spines longer than usual, with the inner spur distinct, but not larger than 

 one of the spines ; outer one long, slender. 



A female which I refer to this species has the head much smaller, being only two- 

 thirds the breadth of the thorax, the eyes small and distant, and the spurs of the 

 posterior tibiae long and nearly equal. 



13. L. i n an a, subcylindrica, testacea nitida, capite rufescente, parcius punctato, clypeo emarginato, for- 

 tius marginato, tborace sat punctato, lateribus subcrenatis, elytris fortius punctatis baud costatis. 

 Long. '45. 



One female, New York, Mr. Guex. Much smaller than the preceding, but similar 

 to it in characters ; nevertheless, the clypeus and thorax and elytra are more punc- 

 tured, the scutellum is strongly punctured, and the elytra are not costate, even near 

 the margin. The pygidium is subtriangular, shining and sparsely punctured. The 

 breast is very slightly pubescent, and the claws are armed with a small tooth at the
