Variations. — This species is rather uniform in size and coloration, 

 but the depressions on the pronotum and pubescence on elytra are 

 more or less variable. In some examples the front of the head is 

 rather distinctly longitudinally depressed, whereas in others the 

 front is convex with scarcely any indications of a depression. 



Host. — The larval habits are unknown, but the adults have been 

 collected by J. O. Pepper in South Carolina on the foliage of oak 

 {Quercus sp.). 



This species was described from a unique male from Texas, and 

 five females collected by J. N. Knull on vegetation along the Olen- 

 tangy River, at Columbus, Ohio. It is allied to lacustris LeConte 

 and can be easily separated from that species by the broadly, deeply 

 emarginate prosternal lobe, but great care must be taken in using the 

 pubescent vittae on the elytra for separating it from allied species. 



The pubescent vittae are at the best very obsolete, and will be 

 somewhat misleading to some students. In most of the specimens 

 examined the surface of the elytra is rather uniformly pubescent, 

 especially posteriorly. The hairs are distinctly separated, and it 

 seems that the only indications of vittae are along the basal half, 

 which is due to the absence of distinct hairs in the humeral region 

 and for a short distance behind the humeri. 



80. AGRILUS MIMOSAE, new species 



Female. — Form moderately elongate, slightly flattened above, and 

 feebly shining; above piceous, with a vague cupreous or aeneous 

 tinge, the head more reddish cupreous in front, and each elytron 

 with a pubescent vitta extending from basal depression to apex; be- 

 neath cupreous brown, and more shining than above. 



Head with the front rather wide, slightly convex, equal in width 

 at top and bottom, the lateral margins nearly parallel to each other, 

 and with a vague, longitudinal groove extending from the occiput 

 to the epistoma; surface obsoletely granulose, finely, irregularly
