Coleopterological Notices, IV. 627 



Legs pale and bright rufous throughout, more elongate ; body more polished 

 and with a distinct aeneous lustre, the elytral striae still finer ; beak in 

 the female longer 22 nitidissima 



Subgenus V. 

 Anterior coxa? separated by fully three-fourths of their own width ; vestiture 

 of the upper surface rather sparse but conspicuous, even, consisting of 

 long white squamules ; prothorax evenly narrowed almost from base to 



apex, the subapical constriction very broad and feeble 23 longula 



Anterior coxae separated by not more than one-half of their own width ; vesti- 

 ture of the upper surface inconspicuous ; prothorax rather pronouncedly 

 subtubulate. 

 Pronotal punctures rather sparse shallow and variolate... 24 rectirostris 

 Pronotal punctures very deep and much denser ; anterior coxae separated 

 by scarcely more than one-fourth of their own width 25 calva 



I. 



1 Liimnobaris bracata n. sp. — Robust and rather strongly convex, 

 oblong-oval, shining, piceous- black, the beak and antennae rufo-piceous ; legs 

 paler, rufous ; vestiture uneven, sparse, whitish, consisting of broad close-set 

 scales in a marginal pronotal vitta and at the base of the third and fifth elytral 

 intervals, also distinct on the scutellar lobe of the prothorax, elsewhere slen- 

 der sparse and inconspicuous but mingled with a few more conspicuous scales 

 on the seventh interval, sparse and uneven throughout beneath. Head 

 sparsely and obsoletely punctulate, the transverse impression distinct ; beak 

 rather slender, evenly, distinctly arcuate, cylindrical, fully as long as the 

 prothorax in the male, finely, sparsely, linearly punctate, more coarsely and 

 irregularly so at the sides toward base; antennae inserted distinctly beyond 

 the middle, the basal joint of the funicle as long as the next three, second one- 

 half as long as the first, outer joints a little thicker, club well developed, the 

 basal joint forming more than one-half of the mass, shining and sparsely 

 pubescent. Prothorax one-third wider than long, the sides feebly convergent 

 and slightly arcuate to apical third, then rounded to the deep subapical con- 

 striction, the apex strongly, conically tubulate, one-half as wide as the base, 

 the latter transverse, moderately lobed in the middle ; disk rather coarsely 

 but not densely and irregularly punctate, with two large discal spots and a 

 broad flat median line impunctate. Scutellum small, glabrous, trapezoidal. 

 Elytra but slightly wider and one-half longer than the prothorax, as wide as 

 long, hemi-elliptical ; striae coarse, deep, not crenulate toward base; intervals 

 one-half wider than the grooves, flat, uniseriately but unevenly and rather 

 coarsely punctate. Abdomen coarsely densely and somewhat rugosely punc- 

 tate. Prosternum separating the rather large anterior coxae by not more than 

 one-half of their own width. Length 3.1 mm. ; width 1.6 mm.

This isolated species is readily distinguishable by its stout convex 

 form, the two impunctate areas of the pronotum and many other
