Dasyneura pergandei n. sp. Male. — Length 1.5 mm. Antemiae dark brown or 

 black; seventeen segments, the fifth having a stem as long as the cylindrical basal 

 enlargement, which latter has a length one half greater than its diameter; terminal 

 segment reduced, narrowly oval, with a length twice its diameter. Palpi; first 

 segment subrectangular, with a length fully twice its diameter, the second a little 

 longer, stouter, the third one fourth longer and more slender, the fourth a little longer 

 than the third. Mesonotum dark brown, the submedian lines fuscous yellowish. 

 Scutellum and postscutellum fuscous yellowish. Abdomen dark red. Wings 

 hyahne, costa yellowish, the slightly curved third vein uniting therewith at the distal 

 ninth. Halteres reddish orange. Legs reddish yellow; claws stout, strongly 

 curved, the pulvilli as long as the claws. Genitalia obscured in the preparation. 



Female. — Length L5 mm. Antennae fuscous yellowish; eighteen segments, the 

 fifth cylindric, with a length twice its diameter; terminal segment with a length 

 twice its diameter and tapering to a subacute apex. Palpi nearly as in the opposite 

 sex. Ovipositor when extended probably as long as the body, the terminal lobes 

 with a length tliree times the diameter, tapering distally and sparsely setose. 



Reared by Theodore Pergande in 1878 from swollen fruit of wild 

 cherry collected by Prof. C. V. Riley at Glenn Ayrie, Col. 



Dasyneura smilacifolia n. sp. Male. — Length 0.75 mm. Antennae dark brown, 

 with fifteen to seventeen segments, the fifth with a stem about three fourths the 

 length of the basal enlargement, which latter has a length two and one fourth times 

 its diameter. The terminal segment may be greatly prolonged, slender and 

 evidently composed of two closely fused, or reduced and sessile. Palpi; first seg- 

 ment irregularly subquadrate, the second with a length about two and one-half- 

 times the diameter, rounded at each extremity, the third a little longer, more slender, 

 the fourth one half longer than the third. Mesonotum reddish brown. Scutellum, 

 postscutellum and abdomen mostly fuscous yellowish, the latter sparsely haired. 

 Genitalia light fuscous. Wings hyaline, costa dark brown. Halteres yellowish 

 basally, fuscous apically. Coxse and femora a pale straw, the tibiae fuscous yellowish, 

 the tarsi a light fuscous, the distal tarsal segments darker; claws slender, strongly 

 curved, unidentate; pulvilh a httle shorter than the claws. GenitaUa; basal clasp 

 segment rather long, moderately stout; terminal clasp segment stout, slightly 

 curved; dorsal plate deeply and triangularly incised, the lobes narrowly rounded 

 and sparsely setose; ventral plate rather short, broad, broadly rounded. Harpes 

 long, tapering, slightly subtruncate and irregularly tuberculate apically. 



Female. — Length 0.9 mm. Antennae dark brown; sixteen subsessile segments, 

 the fifth with a length about twice its diameter; terminal segment reduced, subglo- 

 bose. Mesonotum reddish browTi. Scutellum, postscutellum and abdomen fuscous 

 yellowish, the latter sparsely haired and in some specimens reddish orange. Ovipos- 

 itor fuscous yellowish and nearly as long as the abdomen when extended; terminal 

 lobes slender, with a length nearly four times the width, sparsely and minutely 

 setose apically. Other characters practically as in the male. 



Reared the latter part of August from rolled leaves of Smilax, (green 

 brier) collected by Miss Cora H. Clarke at Magnoha, Mass. Allied 

 to D. clematidis Felt. Type C. a2214. 



Cystiphora vibiirnifolia n. sp. Feynale. — Length 1 mm. Antenna? pale orange; 

 fourteen subsessile segments, the fifth with a length one fourth greater than its 

 diameter; terminal segment reduced, narrowly oval. Palpi; first segment with
