 ])is pedibusqiie pallide testaccis ; capite latiore, vertice 

 fortiter emarginato ; tliorace minus elongato, basin versus

Fern. : abdomine segmento 7° ventrali simplice. 



Antennre very slender, moderately long, almost white ; 

 3rd joint very slender, a good deal longer than the 2nd ; 

 joints 4 — 8 each very slender, and a little shorter than 

 its predecessor (the three terminal joints are Avanting in 

 the individual described). Palpi pale yellow, terminal joint 

 moderately large. Head large, broader than the thorax, 

 and about as broad as the elytra ; the eyes distinctly 

 removed from the posterior angles, the vertical line 

 strongly marked, much deflexed in the middle, owing to the 

 emargination of the vertex, and also interrupted in the 

 middle ; the surface is coarsely and not densely punctured 

 Avith distinct, Avell defined punctures, most numerous 

 between the front part of the eyes, and wanting at the 

 extreme vertex. Thorax rather broad, its length rather 

 less than its AA-idth, a little rounded at the sides, and much 

 narrowed behind ; the surface sparingly and irregularly 

 punctured with Avell-defined punctm-es, these forming a 

 patch on each side the middle ; the sides but sparingly 

 punctured, the smooth spaces well marked but not elevated. 

 Elytra one and a half times as long as the thorax, rather 

 paler in colour than the rest of the upper surface, their 

 punctuation moderately coarse and close. The legs are 

 almost AAdiite. 



Amazons. 



The single female individual, the only one I have seen of 

 this species, is very mutilated, and shoAvs no peculiarity of 

 abdominal structure ; but the species Avill be easily recog- 

 nized by the broad head and the well-defined punctures of 

 the head and thorax, in AA^hich respects it resembles some of 

 the black species here described rather than any other pale 

 species I am acquainted Avith.

 tennis, palpis, pedibusque pallide testaceis ; capite brevi ; 

 prothorace subtransverso, crebre miniis inasqualiter punc- 

 tato ; elytris crebre punctatis, minus nitidis. Long. corp. 

 fere 3 lin.
