lines : thighs dilated : pectus with a large discoidal, very slightly 

 indented space on each side. 



Length three-tenths of an inch. 



[Belongs to Smodicum. — Lec] 



LEPTURA Linn. Fabr. 



1. L. SCALARIS. — Rufous, sericeous; elytra slender, with 

 sericeous triangles along the suture. 



Body elongated rufous, more or less covered with golden seri- 

 ceous ; impunctured : head with a transverse indentation before, 

 and a longitudinal indented line ; space behind the eyes promi- 

 nent: a-- '^nnse rather more than half the length of the body : 

 thorax with a transverse impressed line before, and another be- 

 hind : elytra slender, concavely arcuated on the outer edge be- 

 hind the middle, rounded at tip, considerably shorter than the 

 abdomen ; a darker rounded spot on the middle, and an oblong 

 one behind the middle, so arranged as to exhibit two sutural 

 golden-sericeous triangles on each elytron : posterior thighs 

 blackish at tip : tergum longitudinally black in the middle : be- 

 neath with brilliant golden sericeous hair. 



Length one inch. 



For this fine species I am indebted to my friend. Prince 

 Musignano, who obtained it near his summer residence, at Point 

 Breeze, New Jersey. It is much like the Cerambyx longipes of 

 Drury, 1, pi. 37, fig. 4, [279] but the thighs are not spinous at 

 tip, as in that species. 



2. L. NIGRELLA. — Blackish-brown j thorax cylindrical. 

 Leptura nigra Melsh. Catal. 



Body punctured, somewhat pubescent : head with confluent, 

 small punctures; those of the nasus, and labrum sparse : antennae 

 more than two-thirds the length of the body : thorax cylindrical, 

 very slightly wider behind, punctured like the head ; an obtuse, 

 lightly impressed, transverse line on the anterior submargin, and 

 another on the posterior submargin : elytra with very obvious, 

 numerous punctures, which are more particularly confluent near 

 the base ; tip a little truncated obliquely : beneath dull silvery 

 sericeous. 



Length nearly seven-twentieths of an inch. 



I received this species from Dr. J. F. Melsheimer, under the 

 1826.]
