ment of the membrane of the elytra; the broadest specimen having 

 this organ very little larger than in the other species of the ge- 

 nus, with the wings rudimentary ; whilst in the other the elytra 

 .attain the apex of the abdomen, and the wings appear to be fully 

 -developed.

Genus 2. NOTIUS, n. g. 



Head not much longer than broad, a little narrowed in front, 

 with the anterior angles rounded ; the apex somewhat truncated, 

 with the central lobe as long as the lateral. Ocelli very small, 

 distant, placed close to the posterior angles of the eyes. Anten- 

 niferous tubercles subspinous. Antennae about half the length 

 of the body, rather stout, of five joints ; basal joint shortest and 

 thickest, narrowed towards the base, reaching beyond the extre- 

 mity of the head ; remainder subequal, third shortest, fourth and 

 fifth a little thicker than the two preceding. Rostrum slender, 

 not reaching the posterior coxae ; second joint longest, as long 

 as the third and fourth together, fourth shortest ; basal joint en- 

 tirely enclosed in a canal of the under side of the head ; the walls 

 of this canal very thick. Body oblong ovate, somewhat elon- 

 gate, slightly narrowed in front, depressed. Thorax trapezoidal, 

 with the anterior margin emarginate for the reception of the 

 head, the lateral angles rounded, the lateral margins not denti- 

 culated. Scutellum triangular, with the apex narrow, reaching 

 about the middle of the abdomen. Elytra reaching the apex of 

 the abdomen, but leaving the lateral margins uncovered. Abdo-
