anterior ones), yellow. Wings hyaline, iridescent ; the venation black ; 

 the stigma brown, the lower part paler.. 



Habitat : Palo Alto, California ; Stanford University, California ; 

 Claremont, California (C. F. Baker). 



This species is close to phiricincta, Nort., but the coxae are entirely 

 black, and the femora are darker. 



Macrophya multicincta, n. sp. — Female : Length, 7 mm. Anterior 

 margin of the clypeus truncate ; labrum smooth, slightly notched at the 

 apex, not as long as the clypeus. Supraclypeal fovea shining, not well 

 defined ; middle fovea sublinear, fairly well defined ; lateral ocellar 

 furrows distinct behind the ocelli and above the antennas, in the other 

 places almost wanting ; a distinct furrow extends both forward and back- 

 ward from the anterior ocellus ; orbital carina rather faint ; head behind 

 the lateral ocelli shining and more sparsely punctured than on the front. 

 The third antennal joint not quite as long as joints 4 and 5 combined. 

 The sculpture of all the lobes of the mesonotum the same ; the scutellum 

 more sparsely punctured ; the scutellar appendage granular ; the tarsal 

 claws deeply cleft, the teeth equal. Abdomen with some distinct, 

 irregular punctures ; sheath truncate. Colour black ; posterior margin of 

 the pronotum, tegulse, a spot on the scutellum, most of the basal plates, 

 line on the posterior margin of all the abdominal segments, and most of 

 the venter whitish. Legs black ; posterior coxae beneath, posterior 

 trochanters, the femora above and beneath (these lines do not always reach 

 the bases of the femora), four anterior tibia?, except a black ring at the 

 apex beneath, posterior tibite in the middle, and the tarsi more or less, 

 whitish. Wings hyaline, iridescent ; venation brown, the stigma with a 

 pale streak. 



Type locality : Claremont, California. Three females, collected by 

 Prof. C. F. Baker. 



This species is closest to plurichictella and pluricincta. 



Macrophya melanostoma, n. sp. — Female : Length, 7.5 mm. Anterior 

 margin of the clypeus with a V-shaped notch, the lobes broad and obtuse; 

 labrum punctured with small punctures, the apex truncate, as long as the 

 clypeus. Superclypeal fovea almost wanting ; middle linear ; lateral 

 ocellar furrows distinct, deeper at the vertex and the antennae ; orbital 

 carina almost wanting ; head behind the lateral ocelli shining, but not so 

 much so as in some of the preceding species; third antennal joint as long 

 as joints 4 and 5. Sculpture of all the lobes of the mesonotum the same;
