Photopsis unicolor Cress. 



La Jolla, August. One cf. An interesting variation, having 

 the posterior half of thorax and the legs blackish. This is the 

 first time the species is recorded from any definite locality. 

 Photopsis lingulatus n. sp. 



Allied to albicinda, but distinct by the more sparsely haired 

 abdomen and the almost impunctate second abdominal segment. 



Length, c?, 11.5 mm. Clypeus truncate, the truncation slightly 

 rounded. Mandibles obliquely truncate, slightly notched near the 

 middle of the inferior edge, the truncation Irideulate, the apical 

 tooth strongest, the middle one weakest, front with a median fur- 

 row extending down from the anterior ocellus to between the inser- 

 tion of antenuie, front almost smooth, polished like the rest of the 

 head, which has shallow, indistinct punctures. Space between 

 posterior ocelli greater than that between them and the anterior 

 ocellus and greater than the space between them and nearest eye- 

 margin. Lower margin of eyes almost contiguous with the mser- 

 tion of mandibles. First joint of flagellum about three-fourlhs the 

 length of the second. Prothorax rather coarsely reticulated, only 

 on the sides is there a small area almost smooth. Mesonotum with 

 deep, good-sized, separated punctures; parapsidal groove distinct, 

 deep, extending back almost to the posterior margin. The lateral 

 furrows merely indicated by faint lines. Scutellum convex, with 

 shallow, almost confluent punctures; postscutellum dullish in con- 

 trast to the other parts of the thorax which are shining, sculpture 

 indefinite. Disk of metathorax with a broad almost quadrate 

 polished area, the rest of the metathorax, excepting the greater part 

 of the metapleurre, very distinctly netted, the meshes large, the 

 pits shining. Mesopleuree bulged outward along the middle, the 

 bulged surface irregularly reticulated, bounded by an irregular 

 ridge formed by the termination of the i-eticulation. The depressed 

 portion of the mesopleurse with shallow punctures on the greater 

 part, partly smooth, mesopleuraj below with a few obscure punc- 

 tures, above smooth and shining. Petiole not strongly convex, 

 about twice as long as broad at apex, shining, roughened on the 

 basal half, with a few indistinct punctures on the apical half. 

 Second segment polished dorsad, the punctures are fine and well sep- 

 arated or sparse. Yentrad the punctures are seemingly stronger, 

 on the basal half no distinct i)uucturcs. Kcst of the segments
