GEOLOGICAL SUEVEY OF THE TERRITORIES. 725 



as in Acrulium, with a slight central depression ; frontal costa sulcate ; 

 sides nearly parallel and punctured ; lateral carinai nearly or quite par- 

 allel; eyes as heretofore described. Posterior lobe of the prouotum 

 punctured. Pectus covered with minute hairs. Elytra same length as 

 abdomen. Posterior femora reach the tip of the abdomen. 



Color. — Bright pea-green throughout, except the following mark- 

 ings: Anteuuse rufous except the basal joint, which is green. A 

 small, dusky spot between the eyes, a dark spot beneath the eyes, 

 which is bordered in front by a white stripe. A narrow white 

 stripe runs along the upper margin of each eye, and extends back- 

 ward along the lateral carina of the pronotum. A median dusky 

 stripe runs along the disk of the pronotum, the central portion pale 

 and sometimes almost white; a black stripe extends along the sides 

 of the anterior lobes of the pronotum, which is bordered by white ; the 

 lateral margins have a minute white line along them, sometimes inter- 

 rupted by black punctures. There is an oblique white line on the side 

 of the mesothorax, running to the base of the middle leg ; a similar but 

 larger one on the metathorax, running to the. base of the posterior legs. 

 These lines are generally shaded in front with black. Elytra semi-trans- 

 parent, almost uniform green, there being sometimes a pale ashy-brown 

 shade on the upper (posterior) portion. Wings pellucid ; when living, 

 the front margin is slightly tinged with bluish green, and the posterior 

 half with very pale rufous ; but these shades are often very dim and 

 evanescent. The posterior femora are green, except a rufous band 

 above the knee ; the upper and lower carinre (or ribs) of the disk have 

 generally a thread-like line of white along them, and the upper is some- 

 times bordered above with a pale rufous line. Posterior tibia? green ; 

 spines tipped with black ; tarsi green ; the pulvilli rufous. 



The cross incisions of the pronotum were not dark in these specimens, 

 as mentioned in my original description, which was taken chiefly from 

 alcoholic specimens. 



Dimensiotis. — Length, 1 to 1.10 inches; elytra, .7G inch; posterior 

 femora, .63 inch ; posterior tibiie, .58 inch ; i^ronotum, .25 iugh.
