INSECTS OF SAMOA. 



19. Chariotheca sulcipennis, sp. n. (Text-fig. 4). 



Short, convex, upper side viridiaeneous or cupreous, under side and legs 

 black. 



Head slightly convex between the eyes, strongly and moderately densely 

 punctate, clypeal suture distinct but not impressed nor interrupting the margin 

 of the head, eyes with narrow marginal sulcus ; labrum prominent ; antennae 

 not reaching base of thorax, last six joints produced on inner side, forming a 



loose club. Thorax about twice as wide at 

 base as its median length, sides somewhat 

 arcuately narrowed forwards, with a strongly 

 incrassate border ; anterior angles blunt, 

 scarcely prominent, anterior margin feebly 

 arcuate, finely bordered at sides ; base not 

 bordered, rather broadly prominent in 

 middle ; disc strongly convex from side to 

 side, more finely and sparsely punctate than 

 the head. Scutellum rather large, almost 

 an equilateral triangle, finely punctate. 

 Elytra widest behind the middle, the striae 

 deeply impressed throughout, rather dis- 

 tantly punctate, with intervals strongly 

 convex, very finely and not closely punctu- 

 late ; scutellary stria scarcely indicated, the 

 others ending sharply and separately at a 

 little distance from the base ; posteriorly, 

 the first nearly meets the 9th (marginal) at the apex, the 2nd nearly meets the 

 7th, which here approaches the 9th, the 8th being abbreviated above the third 

 abdominal segment, the 3rd and 6th unite at the apex, while the 4th and 5th 

 may or may not unite, either with one another, or with the next outside them ; 

 the lateral margin rather broad and prominent, but concealed posteriorly from 

 above by the convexity of the elytra ; epipleura impunctate, concave beneath 

 the shoulder, thence flat and gradually narrowed, becoming obsolete about the 

 base of the last ventral segment. Under side nitid, black, for the most part 

 almost impunctate ; men turn with strong median carina ; presternum obtusely 

 carinate in front, the process with an impressed border, propleurae impunctate ;
