 reaching either the suture or the outer margin, black.

Hah. — Grawlor near Adelaide, South Australia. 



This species, which was first sent to this country by 

 Mr. Odewahn, may be at once known from E. alhipennis 

 by the entirely different form of the head ; in the insect 

 now described, that portion of the face on which the 

 antennae are placed, is strongly produced anteriorly and 

 broadly truncate, the eyes being placed laterally halfway 

 between the truncate apex and the thorax. Head coarsely 

 granulose, deeply punctate, the upper surface of the frontal 

 prominence impressed with a deep longitudinal groove. 

 Thorax one-third longer than broad, narrowed from base 

 to apex, sides straight, sinuate just in front of the base, 

 and immediately behind the anterior angle ; disc deeply 

 impressed with large round punctures, each one of which 

 (as well as those on the head) is occupied by a single 

 broadly obovate white scale. Scutellum shining, black. 

 Elytra scarcely broader than the thorax, nearly parijllel, 

 narrowed at the apex, and produced far beyond the, ex- 

 tremity of the abdomen into a distinct tail, the apex of 

 each elytron being still further produced into a short, 

 flat, broad, acute spine; upper surface subcylindrical, 

 deeply striate-foveolate, each puncture being furnished 

 with a single scale, somewhat narrower than those cloth- 

 ing the head and thorax ; each elytron with four 

 distinct costge, the first and fourth unite just before 

 the apex and form a single costa, which runs onwards
