long, shorter thau the seventh, ninth two-thirds wider than the eighth, ob- 

 trapezoidal, outer side more oblique, tenth one-half longer and wider than 

 the ninth, one-half wider than long, eleventh distinctly wider than the tenth, 

 as long as the three preceding together, longer than wido, obliquely acumi- 

 miuate. Prothorax widest at two- fifths the length from the apex; sides 

 strouglj' rounded, feebly inciirvate toward base; the latter broadly, evenly 

 arcuate, three fourths as wide as the disk, nearly two-thirds wider than the 

 apex; disk one-third wider than long, evenly convex, rather coarsely, ex- 

 tremely feebly aud not densely punctate; having in the middle, at one-fifth 

 the length from the base, a small nude punctiform fovea, and, at each side, 

 a larger feebly impressed nude fovea at one-third the length from the base. 

 Elytra at the humeri distinctly wider than the piothorax, together distinctly 

 wider than long, one-half longer than the pronotum, and, at apex four-fifths 

 wider than the latter; disk moderately convex, sutural stria deeply impress- 

 ed, evenly, feebly arcuate; discal tine, distinct, extending very slightly be- 

 yond the middle; sutural foveae very small and at the extreme basal margin; 

 lateral larger and further from the base; base otherwise devoid of foveas; 

 surf ice very minutely, feebly and sparsely punctate. Abdomen two-thirds 

 as long as the elytra, nearly equal in width, occupied for six-sevenths the 

 entire length when viewed vertically by the basal segment; border rather 

 narrow, flat; siarface moderately convex, finely, feebly aud sparsely punctate; 

 basal carinae divergent, straight, strong, nearly one-half as long as the seg- 

 ment, separated by one-half the abdominal width. Legs rather long and 

 slender; posterior tibiae abruptly bent near the apex, middle coxfe large, 

 globose, not prominent, distinctly but narrowly separated by the sternal 

 processes which are truncate and not carinate; posterior small, widely sepa- 

 rated. Length 1.1 mm. 



Texas (Galveston 10). 



Described from the male in wliicli the first two dorsals 

 are simple, the third transversely and feebly impressed, the 

 impression large and anteriorly lunate, the inclosed apical 

 elevation being feebly convex and bearing a loose tuft of 

 long erect set^e ; fourth and fifth normal, broadly arcuate 

 at apex, the latter short and with the posterior margin very 

 feebly jDroduced in the middle. Viewed from beneath the 

 abdomen consists of three visible segments, although there 

 is probably a fourth which is completely hidden under the 

 third; the basal segment is very long, and, in the middle, 

 occupies the entire extent, except a very small apical por- 

 tion where the two short posterior segments become very 

 short, the third being at this point deflexed and channeled
