and the base is Iruncate. The elytral base is tniiu-ate and the hunieri 

 scarcely at all prominent anteriorly. 



In liwmeralis the sides of the pronotum are generally broadly and 

 feebly sinuate behind, with the base more or less rounded : the elytral 

 base is distinctly emarginate with the humeri more or less prominent 

 anteriorly. The two species are found together, with nigrina and 

 tenebTosa at Verdi. 



Humeralis is more asperately sculptured. 



In vandyhei the elytra are simply very finely setose and the integu- 

 ments are shining, in letcheri they are opaque. 



Valuations. — There are no special variations in the series before 

 me. The males have the pronotum more quadrate and the sides more 

 evenly rounded; in the females the pronotal sides are more strongly 

 arcuate anteriorly and straighter posteriorly (Plate 11, figs. 25 and 

 26), and the elytral disc is frequently more depressed, with the sides 

 consequently more strongly rounded. The pronotal marginal bead at 

 the sides may be obsolete. 



This species is dedicated to my friend, the late Beverly Ivetcher in 

 recognition of many favors. 



The mentum is moderate, and the middle lobe quite evenly rounded 

 anteriorly ; surface plane and quite evenly punctate. 



The muricate i)unctures of the elytra when viewed longitudinally 

 appear to be subseriately arranged on the sides. 



The prosternum is more or less feebly convex antero-})osteri()rly 

 betw^een the coxse; compressed and vertically truncate behind, with 

 the angle usually rectangular. 



Mesosternum arcuate and more or less vertical, broadly and feebly 

 concave. 



The tibial grooves of the femora are distinctly concave, with mar- 

 gins well defined and finely asperate. The floors of the grooves are 

 quite glabrous. 



In the males the anterior femora have the anterior margins of the 

 grooves subangulate, thence to the apex sinuate; although (lie 

 femoral tooth is feeble, the species is no doubt related to sjiecies with 

 dentate anterior femora, like gramdata for instance. 



The external borders of the anterior tibiiie, with those of the middle 

 and posterioi- near base, ai'e obsoletely carinale.
