 (Continued from page 484) 



Leptosyna quercus n. sp. Male. Length 9 mm. Antennae extending to the 

 third abdominal segment, rather thickly haired, pale yellowish; 13 segments, the 

 fifth with a stem about three fourths the length of the subcylindric basal enlarge- 

 ment, which latter has a length one fourth greater than its diameter, is distinctly 

 swollen subapically and bears a rather thick subapical band of long, stout setae; 

 twelfth segment subcylindric, slightly expanded and with a length nearly twice 

 its diameter, the thirteenth slightly fused with the preceding, subcylindric, 

 apically a short, stout knob. Palpi uniarticulate, the one segment with a 

 length about two and one half times its diameter, tapering. Mesonotum shin- 

 ing reddish brown. Scutellum and postscutellum pale orange. Abdomen mostly 

 pale whitish yellow, yellowish basally, the genitalia fuscous. The very nar- 

 row wings hyaline, with a thick fringe, the latter having a length about 

 half the width of the wing; subcosta unites with costa near the basal half; 

 the nearly straight third vein extends toward the apex of the wing, becoming 

 obsolete at the distal fifth; the simple fifth vein joins the posterior margin near the 

 basal half; each vein with sparse, long setae. Halteres pale yellowish, reddish orange 

 apically. Legs a nearly uniform pale straw, rather thickly haired. Anterior meta- 

 tarsus with a length two and one-half times its diameter, the second segment twice the 

 length of the first, the third about three fourths the length of the second, the fourth 

 three fourths the length of the third and the fifth one half longer than the fourth. 

 Claws slender, evenly curved, simple, the pulvilli about half the length of the claws. 

 Genitalia; basal clasp segment long, stout, obliquely truncate; terminal clasp 

 segment long, greatly swollen apically, a distinct spur; dorsal plate short, broadly 

 and roundly omarginate, the lobes broadly rounded, chitinized, setose; ventral plate 

 long, broad, broadly round,ed. 



Reared from decaying red oak bark taken at Nassau, N. Y. 

 Type C. a2108. 



Asphondylia eupatorii n. sp. Male. — Length 3 mm. Antennae light brown; 

 fourteen segments. Palpi; the first segment is irregular, with a length about twice 

 its diameter, the second long, tapering distally and with a length fullj^ five times 

 its diameter. Mesonotum dark brown. Scutellum and postscutellum probably 

 fuscous yellowish. ' Abdomen dark brown, thickly clothed with fight hairs. Wings 

 hyaline, costa dark brown. Halteres yellowish basally, fuscous apically. Legs; 

 coxae and the basal two tliirds of femora yellowish, the distal portion of femora, 

 tibia? and tarsi dark brown, except the yellowish tibiae, narrowly fuscous apically, 

 of the posterior legs, while the first tarsal segments and the basal three fourths of 

 the second are silvery white. Genitalia; basal clasp segment greatly swollen; 

 terminal clasp segment short, stout, bidentate; dorsal plate divided, the lobes irreg- 

 ularly orbicular, sparsely setose; ventral plate deeply and triangularly incised, 

 the lobes irregularly rounded and sparsely setose. 



Femafe.— Length 4.5 mm. Antennae dark brovtTi, the third segment having a 

 length about six times its diameter, the terminal segment globose. Other characters 

 practically as in the male.
