8 L.imnobaris planiliscula n.sp. — Oval, rather strongly depressed, 

 polished, hlack, the elytra, legs and beak more or less rnfous, the first some- 

 what clouded with piceous toward the scutellum ; vestiture throughout above 

 and beneath consisting of very small, remote and entirely inconspicuous setae. 

 Head minutely, sparsely punctate, the transverse impression strong ; beak 

 slender, cylindrical, equal throughout, evenly, rather feebly arcuate and not 

 longer than the prothorax, smooth, minutely, sublineately punctured, more 

 coarsely and confusedly so at the sides toward base ; antennas inserted just 

 beyond the middle, the first funicular joint rather robust, as long as the next 

 three, second but slightly longer than wide, a little longer than the third and 

 scarcely more than one-third as long as the first, club moderate. Prothorax 

 about as long as wide ; sides parallel and feebly arcuate to apical fourth, then 

 broadly rounded, convergent and somewhat broadly and feebly constricted to 

 the apex, which is rather more than one-half as wide as the base, the latter 

 transverse, the lobe small and feeble, rounded ; disk rather coarsely, deeply, 

 somewhat unevenly and closely punctate, the punctures always distinctly 

 separated, the impunctate line narrow but evident. Scutellum small, flat, 

 glabrous, anteriorly parabolic, wider behind, the hind margin broadly, evenly 

 arcuate. Elytra but just visibly wider than the prothorax and three-fourths 

 longer, hemi-elliptical, rather acutely rounded at apex, the humeri not pro- 

 minent ; disk with moderately deep striae, the intervals flat, scarcely more 

 than one-half wider than the grooves, each with a single series of fine but 

 deep, irregular and unevenly but generally remotely spaced punctures. Ab- 

 domen shining, the first suture entirely obliterated except near the sides, the 

 first two segments finely, very remotely punctured, the last three rather coarsely 

 and much more closely so. Prosternum flat, the coxae remote, separated by a 

 little more than their owu width, the subapical constriction distinct. Length 

 2.9 mm. ; width 1.0 mm. 



Texas. 



The single specimen appears to be a female, the basal parts of 

 the abdomen being entirely unmodified, but as the male impression 

 is generally very slight indeed in this genus, it is not possible to be 

 entirely certain of the sex, especially in consideration of the short 

 beak.

 (Baridius). 



Oval, depressed above, strongly shining, black, the vestiture con- 

 sisting of small and very sparse setae. Beak slender, cylindrical, 

 evenly, feebly arcuate, as long as the prothorax in the male and 

 one-fourth longer in the female, smooth, polished, finely, sublinearly 

 punctate, more closely so at the sides ; antennae inserted distinctly 

 beyond the middle, the first funicular joint almost as long as the 

 next four, the second more than twice as long as wide but not quite
