302 H. C. FALL. 



allies appear to be chlldii and melwna, from both of which the char- 

 acters given in the table readily separate it. In childii the antennae 

 are obviously longer in both sexes. 



C. agresf is sp. nov. — Head and thorax red, the former black in front, sur- 

 face polished and very sparsely finely punctulate; elytra black, basal margin 

 red, surface coarsely reticulate and subopaque. Head parallel behind the eyes. 

 Antennfe a little longer than the head and thorax in the female, joints elongate- 

 oval or subelliptical ; a little longer and slightly stouter in the male. Thorax as 

 long as wide, slightly narrowed behind, more strongly so in front, sides arcuate. 

 Body beneath black, moderately, closely, finely punctate, with short black pu- 

 bescence. Legs rather slender. Fifth ventral ( % ) rather feebly sinuate at mid- 

 dle ; sixth with a small triangular emargination, which is about as deep as wide. 

 In the female the fifth ventral is truncate, the sixth subsinuate at apex. Tibial 

 spure as in reticulata. Length 15-17 mm. 



Hah. — iVrizona. Two males and one female in the National 

 Museum collection. Probably most nearly related to cribrata, 

 specimens of which I have not seen. The latter is said to have 

 the elytra finely reticulate, which is not the case in agrestis, and 

 there are differences in coloration. 



C stolida sp. nov.— Eather robust, black, or more rarely greenish black, 

 head somewhat shining, thorax and elytra dull. Head subtriangular, evidently 

 broader behind, punctuation rather coarse, moderately coarse at sides, sparser at 

 middle; frontal spot present. Antennae of % scarcely passing the middle of the 

 elytra, joints oval, 4-10 not more than one half longer than wide : third but little 

 shorter than the fourth and fifth united. Thorax nearly as in s^i/^ica. Elytra 

 finely scabrous, almost without pubescence. Fifth ventral of % feebly sinuate, 

 sixth acutely notched and longitudinally impressed, the lateral lobes broadly 

 rounded. Length 8-14 mm. 



Hab, — San Francisco. 



This species is certainly near the black Oregon and Washington 

 forms which constitute the typical stygica. Its more robust form, 

 somewhat shorter and stouter legs, the evidently divergent tempora, 

 and the relatively longer third anteuual joint seem to me sufficient 

 cause for its separation. I take this course with more confidence, 

 inasmuch as specimens sent to Mr. Blanchard and compared by 

 him with the LeConte types, seemed to him clearly distinct. 



C piirpiirasrens sp. nov.— Rather slender, black, with faint purplish or 

 violet lustre, which is more conspicuous on the elytra. The color is very constant 

 in the ten examples before me. The thorax is somewhat more elongate than in 

 ntygica, the pubescence more evident, though sparse, and the antenna {%) are 

 evidently more slender, joints 3-11 —except possibly the tenth— being more than 

 twice as long as wide. Length 7-14 mm.
