Neolasioptera coloradensis n. sp. 



This species was taken by Prof. T. D. A. Cockerell at Boulder, 

 Col., May 12, 1909. 



Female. Length 2 mm. Antennae dark brown; 25 segments, 

 the fifth with a length equal to its diameter, the terminal segment 

 with a length twice its diameter and evidently composed of two 

 closely fused segments. Palpi; first segment stout, incrassate, the 

 second as long as the first, narrowly oval, the third and fourth sub- 

 equal, each about one-half longer than the third and slender. Meso- 

 notum dull dark brown, the submedian lines sparsely haired. Scutel- 

 lum dark brown, sparsely clothed with silvery setae apically, post- 

 scutellum dark brown. Abdomen dark brown, segments one to six 

 with small, submedian, silvery spots posteriorly; venter fuscous; 

 ovipositor pale orange. Wings hyaline, costa dark brown, subcosta 

 uniting therewith before the basal third, the third vein before the 

 basal half, the discal spot long, whitish. Halteres yellowish basally, 

 whitish apically. Coxae fuscous; femora, tibiae and tarsi mostly 

 dark brown, the latter almost black, claws moderately stout, long, 

 the pulvilli shorter than the claws. Ovipositor about two-thirds 

 the length of the abdomen, the terminal lobe extremely slender, with 

 a length about six times its width. Type Cecid. 1350.

 1908 Felt, E. P. N. Y. State Mus. Bui. 124, p. 332 



This species was taken on the office window at Albany, N. Y., 

 August 5, 1907, presumably having been reared from some material. 



Female. Length 2 mm. Antennae dark brown, the basal seg- 

 ments reddish yellow; 17 segments, the fifth with a length about 

 three-fourths its diameter; terminal segment greatly swollen, broadly 

 oval and tapering slightly to a narrowly rounded apex. Palpi; the 

 first segment, short, stout, expanded distally, the second long, nar- 

 rowly oval, the third one-half longer, more slender, the fourth one- 

 half longer than the third and more slender; face with a patch of 

 silvery scales. Mesonotum shining black, variably margined later- 

 ally with silvery white scales, the submedian lines broadly clothed 

 posteriorly with silvery white scales. Scutellum black, with numer- 

 ous silvery scales apically, postscutellum fuscous. Abdomen black, 

 the segments posteriorly with submedian, lunate, silvery white spots 

 and laterally with subquadrate, silvery white spots, forming an 

 almost unbroken, lateral line; ovipositor pale salmon; venter thickly 

 clothed with silvery white scales, except for the narrow, sublateral 

 black lines. Wings hyaline, costa dark brown, the third vein uniting 

 with the anterior margin at the basal fourth; halteres yellowish 

 basally, reddish brown apically. Legs mostly a uniform dark brown. 

 The two distal segments of the posterior tarsi silvery white; claws 

 long, stout, evenly curved, the pulvilli as long as the claws. Ovi- 

 positor nearly as long as the abdomen, the terminal lobes narrowly 

 oval. Type Cecid. 1234.
