than that on lower portion of mesopleurae. Scutelhiin entirely, coarsely 

 reticulate; anteriorly with four longitudinal areas, the two inner formed 

 by the coalescence of four meshes of the reticulum, the two outer by the 

 coalescence of two each. 



Wings with the outer half smoky, a hyaline area on the secoud recu- 

 rrent nervure; second submarginal cell large and pentangular. All tarsi 

 slghty darkened. 



First abdominal tergite very coarsely punctate except on apical border, 

 the crenulate ventral ridge bluntly toothed near the base. Felt lines con- 

 colorous. A fringe of plumose hairs on second segment only. 



This species was collected by the author in King's Cauon, Ormsby 

 county, Nevada. 

 1704 Photopsis uniforniis n. sp. 



Length 10 mm. Ferrug-nous, legs and antennae testaceous, the flage- 

 llum sl;ghtly darker. Second article of flagellum slightly longer than the 

 first. Mandibles tridentate. the lower margin anteriorly cut out to half 

 the basal width of mandible, the emargination subtended by a very large 

 bluntly pointed, slightly darkened tooth. Area within ocelli black. 



The depressed sparsely punctate area on upper part of mesopleurae 

 is very large and broad, tlie narrow border reiraining being very much 

 more weakly sculptured than the lower portion of the mesopleurae. Scute- 

 llum reticulato-punctate. Metanotum coarsely and very regularly reticu- 

 lated, with four larger longitudinal areas anteriorly, the two inner each 

 formed by the coalescence of three meshes of the reticulum, the outer by 

 two each. 



Wings slightly smoky on outer half, with a hyaline area over the se- 

 cond recurrent nervure. First abdominal tergite coarsely rugosely punc- 

 tate at base, to nearly smooth at apex, the ventral crenulate ridge stoutly 

 triangularly toothed basally. Area of felt lines black. The second seg- 

 ment only with a fringe of plumose hairs. 



Specimens of this species were taken occasionally at Clareniont, Los 

 Angeles county, California. 



4335 Photopsis abstrusa n. sp. 



Length 11-12 mm. Color dark ferruginous, tlie legs and antennae paler. 

 Pubescence long, mostly white and unusiially copious, especially on ab- 

 domen. 



Second article of flagellum but slightly longer than the first. Mandibles 

 with the inferior tooth unusually large, the lower margin shallowly emar- 

 ginate on apical half, the subtending tooth low, broad, and very blunt. The 

 silvery ocelli are ringed with black. 



The depressed area on mesopleurae above is thickly punctured, boun- 

 ded caudad by a sharp ridge, beyond which the sculpturing is far 

 weaker and finer than that on lower portion of mesopleurae. Scutellum 

 wholly reticulato-punctate. Metanotum very coarsely but not uniformly
