FAMILY LEPTURID.E. 127 



Leptura HUBRICA. 

 Color black : head and thorax black, pubescent ; four first joints of the antenna* black, 

 the remainder luteous at base. Elytra ferruginous, punctured ; apex of the outer 

 angle pointed, and longer than the inner, divaricate : legs black. 

 I refer this to fig. 10, pi. viii : the apex of the elytra in that figure is truncate. 



Leptura malachiticus. 

 Splendent green, with steel-blue reflections : punctures dilated deep, imparting a rough 

 appearance. Antenna; and scutel black : thighs rufous, and lower half of tarsi dark 

 brown or black : prothorax with a lateral tubercle, occupying nearly a central posi- 

 tion. 

 This beautiful insect is quite rare in the vicinity of Albany, a single specimen only 

 having been observed. 



Leptura octopunctata (Say). 

 Elytra marked with eight irregular-shaped spots or dots, smallest upon the apex. 



Leptura . ( Plate xxvi, fig. 11.)

 what turbinate, third shortest, second the next shortest ; the three first black or dark- 

 brown, the remainder rufous. Pectus and thighs brown, and a stripe beneath the 

 shoulders. The posterior part of the thorax surrounded by a sharp ridge, which 

 extends down the sides : this ridge is bounded by grooves ; and before it, and near 

 the middle, are two elevations, scarcely tubercles : anteriorly it is surrounded by a 

 broad groove. Behind the antenna?, there is a deep depression upon the median line 

 of the head. Length three quarters of an inch.

 outer margin, divergent towards the apex ; apex truncate. Point of abdomen exposed :
