Baring ^or 



This species is allied to submaculata Chmp., from the same region, 

 though probably having a different food-plant; it differs in its 

 larger size, larger prothorax and in the elytral vestiture, which in 

 that species is more or less mingled with dark hair-like squamules, 

 the larger whitish condensed scales forming sharply limited areas 

 about the scutellum and in a large, transversely subquadrate 

 sutural region just behind the middle. The prosternal spines of the 

 male in submaculata are very peculiar, being short, slender, erect, 

 perfectly straight and cylindric. 



♦Centrinaspis plagiatella n. sp. — Oval, convex, rather shining, black, 

 the legs, beak and antennae more or less rufous; upper surface clothed 

 with elongate yellowish squamules, well separated and even on the pro- 

 notum, confused but not dense on the strial intervals, broader and 

 condensed in short lines on intervals three and five near an oblong, 

 sharply defined, chocolate-brown sutural spot from just before the middle 

 to apical fifth, shorter and more or less dense on the under surface: 

 beak in the female rather thick, feebly tapering, strongly, subevenly 

 arcuate and a little longer than the head and prothorax; antennae inserted 

 barely behind the middle, the club narrowly oval and with its first joint 

 two-fifths of the mass, as long as the preceding four joints, the first 

 funicular joint as long as the next three; prothorax short, one-half wider 

 than long, the sides converging, subevenly and rather strongly arcuate 

 to the distinctly tubulate apex, which is half as wide as the base; punc- 

 tures rather coarse, slightly separated, the median punctureless line 

 entire but not very shining; scutellum subquadrate, broadly emarginate 

 behind ; elytra barely a sixth longer than wide, evenly parabolic, rather 

 evidently wider than the prothorax and not quite twice as long, the 

 humeri oblique to the base though scarcely at all tumid; striae deep but 

 not very coarse, the confusedly and loosely punctato-rugose intervals 

 nearly three times as wide as the striae. Length (9) 2.4 mm.; width 

 1.25 mm. Mexico (near Orizaba). 



Allied to lentiginosa Boh., represented in my collection by speci- 

 mens taken in Tabasco, but it differs in its less conical and more 

 transverse prothorax, with much more arcuate sides and more 

 distinct tubulation of the apex, in the broader, more obtusely 

 parabolic elytra, with the post-median sutural brown spot much 

 more sharply defined, and in its smaller antennal club. 



*Centrinaspis deliimbis n. sp. — Subrhomboid-oval, black, with piceo- 

 rufous legs and beak, the upper surface clothed with linear squamules, 

 pale yellowish in color, replaced by smaller dark squamules on the 

 pronotum at each side of the median pale streak, and, on the elytra, 

 forming two or sometimes three lines on each strial interval, becoming 

 dark brown in a feebly defined narrow sutural area behind the middle
