branch indistinct ; cubitus forking slightly distad of the cross vein, both of 

 its branches slightly arcuate. Length, 2.25 mm. 



Type locality: Monticello, 111., June 21, 1914 (J. R. Alalloch). 



Bezzia apicata new species. 



Male. — Head black; scape of antennae black, flagellum, except joints four- 

 teen and fifteen, which are blackened, pale yellow ; antennal plumes pale yel- 

 low ; palpi brown. Thorax deep black, disc subshining, a large white poUinose 

 spot behind each anterior angle on the submedian line, each spot being carried 

 posteriorly for a short distance as a narrow stripe, giving it the appearance 

 of a cornucopia with the wide end towards the anterior margin of disc; scu- 

 tellum black, subopaque ; pleurae subshining on upper, glossy on lower, half. 

 Abdomen whitish yellow, apical three segments and the hypopygium shining 

 black. Legs yellow ; coxae, a distinct band before apex of fore femora, an 

 indistinct one before apex of mid femora, the apical fifth of hind femora, and 

 an indistinct band on fore tibiae and the apices of all tibiae, black ; tarsal claws 

 black. Wings clear, veins almost colorless. Halteres whitish yellow. Tho- 

 racic bristles black, the soft hairs on other parts of body pale. 



Antenna about 1.5 times as long as head and thorax together, joints 

 eleven to fifteen elongated, basal joint globose, large ; eyes separated. Meso- 

 notum with surface slightly granulose, the discal hairs short, rather soft, and 

 numerous, bristles as in fiavitarsis ; scutellum with six marginal bristles. Hy- 

 popygium longer than last segment, the lateral arms slender. Legs slender, 

 fore femora not thickened, the ventral surface with five to six thorns, the 

 other femora without thorns; hind tibiae with distinct soft hairs, but without 

 sctulse ; basal joint of hind tarsi subequal to the length of the next three joints 

 combined ; fifth joint about three times as long as fourth, without ventral 

 spines ; tarsal claws equal, simple, their length about half that of fifth joint. 

 Third vein two thirds of the wing length ; first vein extending to middle of 

 last section of third ; media forking at cross vein, the posterior branch indis- 

 tinct at base, forming an acute angle with anterior branch ; cubitus forking 

 midway between the cross vein and apex of first. Length, 1.5 mm. 



Type locality: INIuncie, 111., IMay 24, 1914 (J. R. Malloch). 



Bezzia dentata new species. 



Female. — Shining black. Head black ; antennae brown, apex of second 

 joint and bases of the short joints of flagellum yellowish ; palpi brown. Meso- 

 notum with whitish pollinose markings as in apicata, postnotum and upper half 

 of pleurae covered with sparse whitish pollinosity, the lower half of latter 

 glossy black. Abdomen unicolorous black, slightly shining. Legs black, fore 

 femora, except on the dorsal surface, mid femora on basal half of the same 

 surface, fore tibiae at bases, fore and mid tibiae at apices, and all the tarsi 

 yellowish. Wings clear, veins brownish. Halteres black, stalks yellow at 

 bases. Bristles on thorax black, the soft hairs on legs pale.
