wing-margin; basal deflection of Rt+a short, about one-third as long as 

 r-tn ; cell Mi lacking ; cell 1st M2 large, nearly as long as vein Ms beyond 

 it; basal deflection of Cmi inserted beyond midlength of cell 1st M2. 

 Abdomen shiny, deep black throughout, including the hypopygium. 



Habitat. — California. 



Holotype, $ (No. 723), Huntington Lake, Fresno Co., alti- 

 tude 7000 feet, July 16, 1919 (E. P. Van Duzee).

6. Ulomorpha vanduzeei, new species 



Size small (wing of the $ 6.5 mm.) ; general coloration 

 shiny reddish yellow; cell Mi lacking; macrotrichise practically 

 confined to the cells of the wing distad of the origin of the 

 sector. 



Male. — Length, about 6 mm. ; wing, 6.5 mm. 



Rostrum yellowish brown ; palpi dark brown. Antennae dark brown, 

 the first scapal segment sparsely gray pruinose ; antennae moderately 

 elongated, the verticils very long. Head dark brown, the vertex surround- 

 ing the antennal fossae more reddish ; head sparsely gray pruinose. 



Mesonotal prsescutum shiny reddish yellow, without apparent stripes ; 

 remainder of the mesonotum light yellow. Pleura yellow. Halteres dark 

 brown, the base of the stem paler. Legs with the coxae and trochanters 

 dull yellow; femora pale testaceous brown, the tips a little darker; tibiae 

 darker brown ; tarsi dark brown : Wings with a faint yellowish gray tinge, 

 much less intense than in U. pUosclla; veins brown macrotrichiae practi- 

 cally confined to the cells beyond the level-^f the origin of Rs, only a few 

 scattered trichiae occurring basad of this, the 2nd anal cell with but one 

 or two trichiae near its distal end. Venation : Sci extending to about two- 

 thirds the length of Rs, Sc2 at the very end of Sci and nearly twice its 

 length ; Rs long, spurred at origin ; cell R2 short-petiolate ; vein Ri almost 

 straight, diverging strongly from Rs so that cell ^2 is conspicuously wider 

 at the wing-margin than cell Rs] basal deflection of Rt+s about one-half 

 the length of r-m ; cell Mi lacking ; vein Ms beyond m longer than cell 

 1st Mi] basal deflection of Cui inserted just beyond midlength of cell 

 1st M2. 



Abdominal tergites dark brown, the sternites more yellowish.
