grooves, the surface fulvous, the sides narrowly edged with piceous ; elytra convex, somewhat widened at 
the middle, finely punctate-striate, glabrous. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
In this small species the thorax is nearly impunctate and has the lateral margins 
piceous ; and the elytra are glabrous and finely punctured.

Two species were confused by me under the name of D. borealis, Chevr., neither of 
which really belongs to it ; one appears to be referable to D. ovata, Lec., the other is 
described below under the name of D. constricta. 1am indebted to Dr. Horn for a 
typical specimen of D. borealis. 
3. Dibolia constricta. | 
Narrowly elongate, black below, above zeneous, cupreous, or blue; thorax bluish, impunctate ; elytra scarcely 
perceptibly punctured in stric anteriorly only ; antenne and legs dark. . 
Length 1-1} line. 
Of narrowly elongate and nearly parallel shape; the head impunctate, the space between the antenne raised ; 
antenne gradually thickened towards the apex, the lower three joints piceous or dark fulvous; thorax 
transverse, with straight sides, dark bluish, opaque, not or scarcely perceptibly punctured; elytra very 
finely rugose, with irregular rows of punctures on the anterior portion, cupreous or bluish ; underside and 
legs black, the posterior femora metallic bluish. 
Hab. Mexico, Las Vigas, Jalapa (Hoge). 
Separable from D. ovata by the narrow elongate shape, the opaque, nearly impunctate 
thorax, the dark antenne and legs, and the finely rugose elytra. Numerous specimens 
were obtained by Herr Hoge at Las Vigas. 
4, Dibolia violacea. 
Oblong-ovate, black, the elytra metallic blue; thorax finely and sparingly punctured ; elytra strongly punctate- 
striate, the interstices nearly impunctate. 
Length 13 line. 
Head deeply inserted in the thorax, the space between the eyes finely wrinkled, the clypeus triangularly
