late, with short blackish suberect hail's, and a narrow median white vitta. 

 Elytra one-half longer than wide and twice as wide as the prothorax, oval, 

 punctate striate, each interspace with a series of fine erect fuscous hairs about 

 equal in length to the width of the first two elytral interspaces; base thinly 

 clothed with similar ochreous hairs, each elytron with an apical, two post median 

 and a subbasal patch of dense appressed white hair. Metasternum and ventral 

 surface densely punctate; pubescence beneath rather dense, white on the protho- 

 racic flanks and parapleural, grayish on the abdomen. Fourth ventral segment 

 two-thirds as long as the third, fifth segment but slightly longer than the fourth. 

 Legs slender, the thighs distinctly but not strongly ciavate; fourth tarsal joint a 

 little dilated, slightly emarginate at apex ; fifth joint inserted upon the upper 

 face of the fourth, narrow, cylindrical ; claws small, divaricate. Length 2.3 2.6 

 mm. 



Described from five examples collected by Mr. Soltau at San 

 A.ntonio, Texas, in June, and now in the National Museum collec- 

 tion. The subbasal spot or spots of white hair are easily removed 

 by abrasion and I do not feel sure of their exact form. The macu- 

 lation is of the same general character as in unilineatus, and this 

 fact, together with its larger size and oval elytra, led me at first 

 sight to suspect it might be the female of that species, as did also 

 M. Pic, to whom I sent a specimen for examination. This is not 

 the case, however, as I have an undoubted female of unilineatus 

 before me ; moreover, the other differences are evidently specific 

 rather than sexual in nature. 



2. Bf. unilineatus Pic. — Very similar to ovipennis, except as follows: the 

 color is entirely black, except the tibiae and tarsi, which are brownish red. 

 Elytra scarcely twice as wide as the prothorax, sides parallel for two-thirds their 

 length ; humeral angles right, narrowly rounded. Auteunas a little stouter, the 

 pubescence of the first eight joints largely whitish, that of the last three blackish 

 in color. Prothorax more sparsely granulate, the granules well separated, the 

 surface between them shining. Elytra without ochreous hair at base, the sub- 

 basal fascia of white hair well developed, straight at sides, posteriorly angulate 

 on the disk and attaining the suture close to the scutellum. As in ovipennis the 

 pubescence of the legs is white exteriorly, but yellowish or grayish interiorly. 

 Length 2-2.4 mm. 



Brownsville, Texas. Specimens collected by and received from 

 Mr. Schaeffer. Others are in the National Museum collection. The 

 identification of this species is due to M. Pic, to whom I sent an 

 example for examination. He writes that the Brownsville speci- 

 mens differ slightly from his type, which was described from an un- 

 known locality in Mexico, but that the differences are too small to 

 be considered specific.
