punctate; wings slightly infuscated, veins, including costa and 

 stigma, black ; saw-guides with sides parallel, distal end 

 broadly rounded. Length 8 mm. 



Habitat: Ithaca, New York. No. ii-i. 



Related to tibiator Nort. but with a different punctuation of 

 the head. 



Macrophya flicta n. sp. — Female. Body black with the fol- 

 lowing parts white : clypeus, labrum, a line on the mandibles, 

 line on collar and tegulse, procoxae, distal half of mesocoxse, 

 spot on metacoxas, trochanters, ring on proximal end of 

 femora, cephaHc surface of distal four-fifths of profemora, 

 spot on distal end of cephalic surface of mesofemora and meta- 

 femora, larger on the former, cephalic surface of protibias 

 and mesotibise, spot near middle of dorsal surface of meta- 

 tibise, all of tarsi except a distal black ring, and a spot on the 

 mesal part of the basal plates ; clypeus broadly deeply emar- 

 ginate; antennae with third segment as long as or longer than 

 fourth and fifth together ; head setaceous, hoary, especially in 

 antennal region, polished throughout, except for calices for 

 insertion of setsCj larger on postocellar area ; median fovea 

 large, deep, twice as long as broad ; occipital furrows wanting ; 

 mesonotum with sparse fine pits, larger on mesoscutellum ; 

 wings hyaline, veins and stigma and costa black ; saw-guides 

 with straight dorsal margin, convex ventral margin, and blunt 

 oblique distal end. Length 9 mm. 



Habitat: Ithaca, New York. No. 126-3-C-1. 



This species is similar to flaccida but the smooth head and dif- 

 ferent shaped saw-guides will differentiate them. 



Macrophya fistula n. sp. — Female. Body black with the fol- 

 lowing parts white : clypeus, labrum, mandibles in part, line on 

 collar and tegulse,, procoxae, distal end of mesocoxae, large spot 

 on lateral aspect of metacoxae, trochanters, cephalic aspect of 

 profemora, distal half of cephalic aspect of mesofemora, ring 

 on proximal and distal ends of metafemora, cephalic aspect of 

 protibiae and mesotibiae, short band on dorsal aspect of middle 

 of metatibiae, tarsi except fuscous ring on the distal end of 

 each segment, and small spot on mesal part of basal plates ; 

 clypeus broadly emarginate, bottom of emargination broad and 

 straight ; antennae with third segment about as long as fourth 

 and fifth segments together ; round deep fovea on meson about 

 midway between median ocellus and antacoriae ; head densely
