12. Neosciara luteola n. sp. 



Male: Length, 1.5 mm. Head luteous; antennae about as long as 

 body, fuscous with scape luteous; segments at least twice as long as 

 wide; palpi luteous. Thorax luteous, shining. Abdomen; dorsum 

 brownish with posterior margin of each segment luteous; venter 

 luteous. Hypopygium luteous, with no median ventral lobe at base; 

 clasper (Fig. 12) with 5 or 6 subapical stout spines and one more slender 

 slightly longer spine, one or two of the most proximad spines points more 

 cephalad than the rest, several very small seise proximad of the stout 

 spines. Legs luteous, trochanters black. Wings (Fig. 43) hyaline; 

 media and cubitus without setae; base of R^ slightly distad of the mid- 

 point between the humeral cross vein and the tip of Ri; Ri ends 

 proximad of the forking of media; petiole of cubitus less than half the 

 length of the base of the media; costa extends a little over half the 

 distance between the tips of Rs and Mi; Rs ends slightly proximad of 

 .85 the length of the wing and proximad of M2. Halteres luteous. 



This species is closely related to mellea, but differs in the 

 structure of the clasper and the color of the body. 



Described from 2 males collected at Black Rock, Rabun 

 Co., Ga., May 20--23, 1911. Type No. 217, and one paratype.

 fuscous fiagellum and fulvous scape; palpi fulvous. Thorax sub- 

 shining, fulvous, with a broad median dorsal indistinct fuscous line on 

 the mesonotum. Abdomen fuscous. Hypopygium fuscous, at base with 

 a median ventral lobe covered wi.th minute setae (Fig. 13b); clasper 

 (Fig. 13a) with a large apical spine and no subapical spines. Legs: 

 coxae luteous, trochanters fuscous, tibice fulvous, tarsi fuscous. Wings 

 (Fig. 44) hyaline; media and cubitus without setae; base of Rg distad of 

 the mid-point between the humerus and the tip of Ri; Ri ends dis- 

 tinctly proximad of the forking of media; petiole of cubitus over half 

 the length of the base of media; costa extends a little over half the dis- 

 tance between the tips of Rs and Mi; Rs ends distad of .85 the length 

 of the wing and about opposite the tip of Mo. Halteres; knobs fuscous, 

 pedicels luteous. 



This species differs from ocellaris by having a median 

 ventral lobe on the hypopygium, and a clasper with only one 

 apical spine.
