Eagle Pass, Rio Grande, Texas, Mr. A. Schott; abundant in Mexico. A very small 
yellow sutural spot near the apex of the elytra is visible in one specimen; in another, the 
lateral yellow stripe includes a marginal black dot near its termination. The red tint of 
the posterior band is sometimes wanting. The striae at tho sides and tip are very deep, 
so that the intervals become convex. The 3d and 5th intervals are slightly elevated at 
the base. The last ventral segment has a broad shallow marginal groove, with a faint 
transverse carina near the apex. 
2. A. opacula, cuneiformis, acnco-nigra, hirta, fronte vix impressa, thorace latitudine plus duplo breviore, 
lateribus obliquis rotundatis, fortiter marginatis, ante basin latiore, rude punetato, minus dense in medio, triangu¬ 
lariter late excavato, versus latera late foveato, lateribus flavis, margine suuimo nigro-icneo, elytris thorace angus- 
tioribus, a basi angustatis, postice magis attenuatis fortiter serratis singulatim subrotundatis, punctis quadratis 
seriatis, striis externis et ad apicein profundis, interstitiis angustis uniseriatiui punctulatis, maculis pluribus satu¬ 
rate flavis, posticis rufo-tinctis; subtus parce pubeseens. Long. ’42. Tab. XII. fig 3.
