3 TO Coleopterological Notices, IV. 



near the middle of each elytron ; el3'tra and beak toward apex 

 bristling with stiff suberect setae. Beak in the female not very- 

 stout, evenly, feebly arcuate, as long as the head and prothorax, 

 rather sparsely puactate and siibglabrous except above in basal 

 half, with an elongate indentation between the antennae, the latter 

 inserted just behind apical third, the basal joint of the funicle not 

 quite as long as the next three ; club moderate, not darker in color. 

 Prothorax two-thirds wider than long, parallel and rounded at the 

 sides, convergent and just visibly constricted anteriorly, the apex 

 nearly three-fourths as wide as the base ; disk rather finely, some- 

 what closely punctate, without distinct impunctate line. Elytra at 

 base barely one-fourth wider than the prothorax, three and one-half 

 times longer than the latter, subparallel, ogival in apical third, the 

 striae feebly impressed, the punctures rather small, not very close- 

 set ; erect setae forming a single line on each interval. Length .3.7 

 ram.; width 1.65 mm. 



California (San Diego). Cab. LeCoute. Represented by the 

 unique female type. Hirtits is allied to hi/stricula, but is immedi- 

 ately distinguishable by its larger and more transverse prothorax, 

 stouter bodily form, longer beak, very much finer strial punctua- 

 tion and many other characters. The erect setae of the elytra are 

 decidedly shorter and more numerous than in hydricula. 



10 D. filiolus n. sp. — Obloug-oval, rather stout, convex, sliinius', pale 

 flavate throughout; vestiture rather sparse, consisting of long, somewhat fine, 

 recumbent and ashy pubescence, not perceptibly variegated, the elytra brist- 

 ling with long sparse and erect bristles, disposed in a single line on each 

 interval. Head and beak finely, rather densely, evenly punctate, the frontal 

 fovea deep but not very large ; beak short, stout, just visibly, evenly arcuate, 

 about as long as the prothorax in the female, not longitudinally furrowed or 

 carinulale ; antennae inserted beyond apical two-fifths, somewhat stout, short, 

 the basal joint of the funicle as long as the next three, seventh abruptly wider, 

 transverse, club short, very robust, oval. Prothorax short and transverse, two- 

 thirds wider than long, strongly rounded on the sides, convergent and nearly 

 straight but not in the least constricted toward apex, the latter much narrower 

 than the base ; punctures rather coarse, very deep and dense but not actually 

 in contact, and with traces of a narrow impunctate line. Elytra at base one- 

 third wider than the prothorax, three and one-half times as long, subparallel, 

 the apex conjointly ogival ; strise feebly impressed, coarsely, deeply and closely 

 punctate, the intervals very minutely, feebly, sparsely and indistinctly punc- 

 tured. Abdomen shining, fin(dy, not very closely, distinctly punctate, sparsely 

 and finely pubescent. Length 2.5 mm. ; width 1.15 mm.
