area and forming single interstitial lines, becoming finer, darker and 

 indistinct on the elytral flanks; squamules beneath whiter, sparse and 

 slender on the propleura, shorter, broader and close-set on the hind body; 

 beak (cf ) thick, fully half as long as the body, strongly, evenly arcuate, 

 gradually tapering and distinctly sculptured throughout, the antennae 

 at three-sevenths, or (9), smaller, more slender and shorter than in the 

 male, more feebly arcuate, slightly longer than the head and prothorax, 

 tapering, nearly smooth except basally, with the antennae also at three- 

 sevenths; prothorax two-fifths wider than long, the sides strongh , 

 evenly arcuate, becoming less so and parallel in basal half, the feebly 

 constricted apex much less than half as wide as the base; punctures 

 very coarse, narrowly separated; scutellum obtriangular, smooth, flat 

 and nude; elytra scarcely longer than wide, parabolic, a little wider 

 than the prothorax and one-half longer; grooves rather coarse; intervals 

 one-half wider than the grooves, each with a series of coarse and rounded 

 punctures; under surface strongly and closely punctate; anterior coxae 

 separated by their own width, the prosternal surface flat and coarsely 

 punctate in the male. Length (cf 9) 2.65-2.8 mm.; width i. 2-1. 35 

 mm. Mexico (Frontera, in Tabasco), — Townsend. Three specimens. 



The much larger and longer beak in the male than in the female, 

 is a very exceptional character, but also occurs, I believe, in some 

 of the Madarids. The female is also smaller and slightly narrower 

 than the male. In the present species the pygidium of the male 

 is vertical, prominently convex and separated from the propygidium 

 by a transverse suture; in the female it is not quite so convex and is 

 sensibly oblique, though entirely exposed; the body is larger, the 

 form more obese and the pubescence much more conspicuous than 

 in expo situs Chmp. 



The following species has the beak in the male similarly large, 

 stout, arcuate and strongly sculptured, though less tapering and 

 relatively not quite so long, the body more narrowly oval and very 

 convex, and the elytral striae very much finer: 



*Limnobaroides bakeri n. sp. — Rather stout, oval, only moderately 

 convex above, deep black and shining, the legs short and clear rufous; 

 scales of the upper surface whitish, sparse and slender on the pronotum 

 and forming single incomplete series on the strial intervals, close and 

 more distinct beneath, though mostly denuded in the type; beak in the 

 male rather strongly sculptured and dull, moderately and subevenly 

 arcuate and fully half as long as the body, feebly tapering from base to 

 apex; prothorax a third wider than long, the sides subparallel and broadly 

 arcuate, gradually more rounding anteriorly to the tubulate apex, which 

 is fully half as wide as the base; punctures coarse, separated by their own 

 diameters, the smooth median line entire; scutellum quadrate, nude and 

 flat, broadly emarginate behind, with acute angles; elytra barely a fourth 

 longer than wide, very obtusely, subevenly parabolic, slightly wider
