H. C. FALL. 163 



flat, very little, wider tliau the striae. Beneath nioderately punctate; legs rather 

 slender. Length 2 mm. ; .08 inch. (PI. V, fig. 6). 



The unique type, from which the above description was taken, 

 was collected by Mr. Schwarz at San Diego, in Southern Texas, and 

 is now in the collection of the Department of Agriculture. 



The superficial resemblance to a small segnipes is rather marked, 

 but the color of the antennae, with the much shorter basal joint, the 

 shape of the ro.strum, finer punctuation, more longitudinally convex 

 elytra and difference in vestiture, show it to be abundantly distinct. 



84. A. filuiii n. sp. — Very elongate, black, moderately pubescent. Beak ( 9) 

 longer than the heail and thorax, slender, cylindrical, very feebly dilated near 

 the base: the tip a little broader; surface shining; punctuation sparse, fine. 

 First joint of antennse equal to the two following, second reaching the eye. 

 Front narrower than the tip of the beak, punctate, not sulcate; eyes not promi- 

 nent. Prothorax subcylindrical, a little longer than wide, a little wider at one- 

 third from the base, rather coarsely, moderately closely punctate, with elongate 

 basal fovea. Elytra narrow ; humeri small; sides feebly arcuate, widest behind 

 the middle; intervals feebly convex, scarcely twice as wide as the strife. Abdo- 

 men almost impunctate ; legs slender. Length 1.5 mm. ; .06 inch. (PI. V, figs. 

 9 and 9rt), 



Described from a single female specimen from San Borja, Lower 

 California, in the collection of the California Academy of Sciences. 

 In the absence of the male it cannot be certain that this species 

 belongs in the present section. The small size, narrow form, feebly 

 longitudinally convex elytra, narrow front and remotely punctate 

 abdomen will, however, easily separate it from anything else in 

 our fauna. 



85. A. ventrico!<»uin Lee. — Form obese, black, with or without aeneous 

 lustre; pubescence moderate; beak rather stout. cylindrical, not dilated, suhequal 

 to the head and prothorax, slightly longer in the 9 i '"ather finely, sparsely punc- 

 tate above, more coarsely subseriately at the sides; supra antennal groove more 

 or less distinct. Antennae slender, first joint about as long as the next two, sec- 

 ond reaching the eye. Front narrower than the tip of the beak, not sulcate, 

 either nearly impunctate, or with punctures arranged in two more or less regular 

 longitudinal rows; eyes not prominent. Prothorax small, wider than long; 

 sides feebly diverging, slightly contracted in front; surface not closely, usually 

 somewhat irregularly, superficially punctate, a short foveate line at base. Elytra 

 ventricose, not much longer than wide; humeri small, post-humeral sinuatiou 

 lacking; sides arcuately diverging to apical two-fifths, thence more suddenly 

 rounded to apex ; intervals usually fully twice as wide as the striae, more or less 

 convex. Beneath rather sparsely punctate; legs slender, last tarsal joint very 

 long, projecting beyond the lobes of the third about twice their length ; claws 

 with a small acute tooth. Length 1.4-1.8 mm.: .06.07 inch. (PI. V, figs. 12 

 and 12a).
