COLEOPTERA- CAEABID.E. 527 



Pterostichus fractus. 



ri. 1, Figs. 29, 30. 



Closely allied to P. destitutus, with the same early union of the fifth 

 and sixth striae., not shown in the figure, but still smaller and with less dis- 

 tinct strlal punctuation, this being indeed very inconspicuous. A single 

 elytron is preserved, with the extreme apex broken. There is a distinct 

 punctum in the third interspace opposite the union of the fiftji and sixth 

 stripe, which is just before the break. The interspaces are flattened, as in 

 P. destitutus, and the intimate structure of their surface is exactly as there, 

 except in showing scarcely any sign of reticulation. 



Length of fragment, 4.5'"""; breadth, 2""'.

Pterostichus desteuctus. 



PI. 1, Fig. 46. 



A couple of elytra, from each of which the entire apex is broken, 

 closely resemble P. patruelis Dej in shape and sculpture, but represent a 

 species a little larger than it. The sutural stria is exactly as in that species, 

 and the striae are finely impressed and without punctures ; the interspaces 

 would appear to be flatter than in P. patruelis, and the third interspace does 

 not appear to have the three punctures found in that species, but only the 

 central one. The color is blackish castaneous. 



Length of one fragment, ;5.5"" ; probable length of elytron, 4.75""' ; 

 width of same, L5°"". Length of another fragment, 3.8°"°; width, 1.45°"°.

The following fragments of this species have been examined : A very 

 nearly perfect elytron, but badly cracked and pressed apart ; the greater 

 part of another; parts of three united segments of the abdomen ; the pro- 

 thorax slightly cracked ; and a portion of one of the mandibles. A species
