a pair of piuictiform impressions, between these impressions are several 

 large punctures, but not in a regular transverse series as in Scaphidium ; 

 elytra with six discoidal rows of punctures : the four rows nearest the 

 suture reach the base, but not the apex, and the two external ones neither 

 base nor apex ; the first row also terminates towards the base in three 

 large distinct punctures, and from the base of the third runs a transverse 

 row, as in Scaphidium, to the sutural furrow, which is impunctured : the 

 egs are pale chestnut. 



[lIO.j FAMILY ANISOTOMID/E. 



156. Leiodes puNCTO-STRiATUS A^r^^', — Length of body i hue. -A 

 single specimen taken in Lat. 65'. 



Body hemispherico-ovate, naked, glossy, chestnut. Head very lightly 

 punctured ; mandibles rather prominent ; palpi and antennae rufous, cjava 

 of the latter much incrassated consisting of five joints, the second of which 

 is extremely minute : prothorax very large, wider than long, very lightly 

 punctured, vvith the sides paler than the disk : elytra deeply and grossly 

 punctured in rows, interstices impunctured ; legs and under-side of the 

 prothorax rufous : anus paler than the rest of the abdomen. This species 

 closely resembles the Anisotoma badia of Sturm, but the elytra are not 

 JineJy punctured, as Mr. Stephens describes them in that species.

157. CoRTiCARiA DENTicuLATA Kirby. — Length of body i line. A 

 single specimen taken in Lat. 65 . 



[iii.l Body dark piceous, rather glossy, naked, minutely punctured. 

 Prothorax rather orbicular, with a circular deepish impression just above 

 the scutellum ; sides distinctly denticulated : elytra with several rows of 

 punctures. The insect here described approaches very near to C. impressa 

 Marsham, but it is sufliciently distinguished not only by its colour but 

 chierty by the very visibly denticulated siu?s of its prothorax. [As the 

 pecific name of this insect is preoccupied, it has been named C. Kirbyi 

 by Ur. l>e Clonte. Taken by Agassiz's Expedition on the north shore of 

 Lake Superior.]
