with outer half very slightly smoky; second submarginal cell small, 

 about half of the length of the first, its angles all rounded, making its 

 general form oval. 



First abdominal segment much shorter and thicker than usual, above 

 retieulato-punctate throughout, the crenulate ventral ridge strongly si- 

 nuate and with a sharp Ijasal tooth. Felt lines concolorous. Segments II 

 and III have well developed apical fringes of plumose hairs. 



This well r. arked little species was taken at (;iaremont, California. 



4337 Photopsis insignis n. sp. 



Length 9 mm. Color ferruginous throughout, the tibiae and tarsi a little 

 darker and the flagellum piceous. Pubescence mostly bright oehraceous, 

 rather short on the abdomen. Mandibles tridentate, emargination deep 

 and subtended by a very large, blunt, dark tipped tooth. Head conco- 

 lorous. Ocelli black, the two posterior distinctly nearer to each ather than 

 to the eyes. 



Mesopleurae retieulato-punctate, smooth for some distance over the 

 mid-coxae, above with a rather sharp transverse groove, the sparsely 

 punctate area small, not sharply demarked, the remainder sculptured like 

 that below. Scutellum with rather sparse indented punctures. Metanotum 

 coarsely, sharply, but quite irregularly reticulate with four median lon- 

 gitudinal areas at base, the two median each formed by the coalescence 

 of about four meshes, the two lateral each by about two meshes of the 

 reticulum. Wings with outer half smoky and a hyaline area over second 

 recurrent nervure; the second submarginal cell is large and sharply pen- 

 tangular. 



First abdominal tergite rugoso-punctate to near the apex, the crenulate 

 ventral ridge strongly sinuate and with a sharp tooth at base. Felt line 

 concolorous. The second segment only has an apical fringe of plumose 

 hairs. 



Occasional at Claren:ont, California. 



433S Photopsis pedatus n. sp. 



Length 12-13 mm. Color pale ferruginous, the legs, scape and funicular 

 article of antennae testaceous, the flagellum piceous. Pubescence above 

 largely pale oehraceous. The bidentate mandibles have the lower side 

 very deeply emarginate leaving the distal portion unusually slender, th-^ 

 subtending tooth large, broad, and very bluntly rounded. Interocellar 

 space slightly darkened; the hind ocelli large and nearer to each other 

 than to the eyes. 



Mesopleurae deeply cut to three fourths of the width by a deep trans- 

 verse groove, the disc below this strongly rticulato-punctate, above the 

 depressed area is sparsely punctate and the remaining ridge rugoso-punc- 

 tate. Scutellum coarsely rugoso-punctate. Metanotum coarsely, sharply 

 and somewhat irregularly reticulate, with four basal areas, two median 

 longitudinal formed by coalescence of about three meshes and two outer
