Twelfth Report of the State Entomologist 227 



thickly specked with fuscous; anterior veins black, the others a smutty 

 yellow. Knobs of halieres fuscous, pedicel yellowish. Coxae and legs 

 dark brown to black, the anterior coxse sometimes lighter ; tibial spurs 

 yellow. 



Antennae equal in length to head and thorax ; the two enlarged basal 

 segments globose ; 3d to 15th segments nearly cylindrical, about twice 

 as long as thick; terminal segment subconical. Palpi; basal segment 

 short ; second irregular, rounded dorsally ; third a little shorter than 

 second, subrectangular in outline ; terminal segment as long as second, 

 slender; both large and small setae exceptionally stout and numerous; 

 smaller, verlicillately arranged. 



Thorax with scattering setae. Wings: subcosta (ist longitudinal) 

 short; first branch of radius (2d longitudinal) joined to the second 

 branch (3d longitudinal) about midway of its length by the short 

 cross-vein and uniting with costa at the outer third of the wing just 

 beyond the fork of media (4th and 5th longitudinals); second branch of 

 media (5th longitudinal) nearer the apex of the wing than the tip of the 

 second branch of radius; the distance between the two branches of 

 cubitus (6th and 7th longitudinals) along the margin of the wing is 

 greater than that between the second branch of media and the first 

 branch of cubitus (PL VI, figs. 8, 9). Fore coxa a little over half the 

 length of either femur or tibia; tarsi one-fourth longer than tibia; 

 first tarsal segment shorter than the remaining four; femur and tibia 

 of middle pair longer, of the posterior still longer, than those of the 

 anterior legs ; first segment of middle tarsi not quite so long as the 

 remaining segments, while that of the posterior is longer. 



Abdomen sparsely clothed with fine sets. The distended abdomen of 

 the female enlarges to the third or fourth segment, and then tapers 

 gradually to the slender ovipositor, — terminal portion of the genital 

 plates oval. 



The male differs in having a nearly cylindrical abdomen which is 

 vested with stouter setae. The basal portion of the enlarged terminal 

 segment is unusually stout and the claspers are comparatively weak and 

 irregular. Tips of the claspers terminated by a stout recurved spine and 

 by numerous straight bristles on its inner margin. 



Length: male, body 4.4 mm., wing 3.7 mm.; female, body 5.6 mm., 

 wing 5 mm. 



Males of the following species were reared by Dr. Smith from decaying 



blackberry roots. They resemble Sciara ochrolabis Loew closely, but 



differ from the types in the antenuce being barely as long as the head 



and thorax, while in ochrolabis they are longer. The basal joints of the 



antennae in Loew's species appear to be much shorter than in the insect 



under discussion. It will also be found that the terminal abdominal' 



segments are more hairy and the claspers more triangular than in 



ochrolabis. 



SciARi FULvicAUDA n. sp. Face ochreous ; vertex dark ochreous ; 

 scape of antennae yellow, flagellum dark ochreous with a rather dense 

 whitish pubescence ; palpi fuscous ; dorsum of thorax yellowish to rufous, 

 the scutellum of the metathorax with variable dark stripes, in some
