Baring 391 



median basal lobe rather abrupt, rounded; elytra but little longer than 

 wide, arcuately acuminate from the base, slightly wider than the pro- 

 thorax and two-thirds longer, the humeri moderately prominent. Length 

 (9) 3.0 mm.; width 1.28 mm. British Honduras (Rio Hondo), — 

 Blancaneau. Received from Mr. Champion. 



Differs from two species, which are both labeled lineelhis, in its 

 smaller size and different disposition of the dense white vittse of the 

 elytra; in both the forms referred to, supposed to represent lineelhis 

 Lee. (erroneously described as from California), the fourth stria! 

 interval is densely whitish only in basal fourth, and the white scaly 

 crust of the sixth only extends to barely beyond the middle of the 

 length. 



Centrinaspis n. gen. 



This genus, the type of which is Centriniis perscillus Gyll., is a 

 very large one. The body is of moderate to very small size, ovulate 

 and convex, suboval or rhomboidal, the surface as a rule densely 

 clothed with decumbent scales, lineiform or suboval, and the pro- 

 sternum of the male has an erect spine, very moderate to small in 

 size, or frequently wholly wanting. The anterior coxae are generally 

 rather well separated, and the prosternal surface unmodified, 

 excepting sometimes in an anterior pit as in podagrosa. Besides 

 perscillus, our fauna includes perscitus and picummis Hbst., neglediis 

 Lee, and albotectus, grisescens , finitimus , exulans and clarescens Csy. 

 Among the Mexican representatives are pugnax, podagrosus, 

 crucifer, basinotatus and siibmacidatus of Champion, all originally 

 referred to Gerceus, and also Cenlrinus lentiginosiis Boh. 



Centrinaspis vitula n. sp. — Elongate-oval and rather convex, black 

 throughout and clothed closely with elongate slender yellowish scales, 

 mingled with some darker ones on the elytra, the under surface with 

 denser and more oval whitish scales; beak arcuate, about half as long 

 as the body, rather thick and cylindric, with the antennae inserted at 

 four-sevenths {&), or thick basally but very thin and smooth beyond 

 the antennae, which are inserted near the middle, (9 ), antennae slender, 

 the first funicular joint as long as the next three; prothorax a fourth (cf) 

 to a third ( 9 ) wider than long, the sides feebly converging and nearly 

 straight, obliquely rounding in apical third, the apex but feebly con- 

 stricted and much less than half as wide as the base; punctures coarse 

 and in mutual contact but not coalescent; median line narrow, subentire, 

 smooth; elytra two-fifths (9) to a little more (c?') longer than wide, 

 slightly wider than the prothorax and not quite twice as long, arcuately 

 and obtusely acuminate throughout; striae deep, the intervals coarsely,
