apically long digitate processes arising from circular pores. Terminal seg- 

 ment somewhat produced with a length over twice its diameter and tapering 

 to an irregularly rounded apex. Palpi, basal segment irregular, second segment 

 with a length over twice its diameter, the third as long as the second, more 

 slender, the fourth nearly V 2 longer than the third and somewhat dilated. 

 Mesonotum reddish brown. Scutellum brownish yellow. Postscutellum darker. 

 Abdomen mostly fuscous yellowish, fuscous apically. Wings moderately broad, 

 rather thickly haired and with a venation suggesting that of Joannisia. Sub- 

 costa unites with costa before the basal half; there is a distinct cross vein 

 originating at the distal ; .hird of subcosta and the third vein joins the margin 

 at the apex of the wing, fourth vein extremely indistinct and only traces of 

 the fifth vein are to be seen. Halteres and legs fuscous yellowish. Claws 

 moderately long, stout, somewhat irregular. The pulvelli rudimentary. Ovi- 

 positor short, triarticulate, the basal two segments irregularly rectangular, the 

 terminal segment broadly oval and sparsely setose. Type Cecid. 17 10. 



Neocatocha sylvana new species. 



The peculiar female described below was taken September 6, 1917, 

 by Mr. Howard Notman at Keene Valley, N. Y. It is easily distin- 

 guished from other American forms by the small number of antennal 

 segments. 



Female. — Length 2 mm. Antennae l /z the length of the body, dark brown, 

 10 segments, the fifth with a stem Yz the length of the somewhat ovate basal 

 enlargement, the latter with a length l / 2 greater than its diameter, sparsely and 

 irregularly clothed with moderately short setae and apically with a series of 

 digitate processes rising from circular pores ; terminal segment somewhat re- 

 duced and tapering to an obtuse apex. Palpi, first segment irregularly quad- 

 rate, the second a little longer and more slender, the third as long as the 

 second and more slender, the fourth twice the length of the third. Mesonotum 

 shiny dark brown. Scutellum and postscutellum shiny reddish brown with 

 a darker transverse band near the middle. Abdomen fuscous yellowish. Wings 

 slightly fuscous, iridescent, the third vein uniting with the margin before the 

 apex of the wing, the fourth vein indistinct and with a relatively short fork. 

 Halteres dark brown. Legs mostly dark reddish brown, the tarsi with a yel- 

 lowish cast. Claws simple, finely denticulate apically, the pulvilli as long as 

 the claws, the eighth abdominal segment ventrally with submedian ovate 

 organs. The ovipositor short, triarticulate, the terminal lobes narrowly oval 

 and sparsely setose. Type Cecid. 1720. 



Joannisia borealis new species. 



The small midge described below falls in the series with the termi- 

 nal clasp segment broadly rounded apically. It is easily separated 

 from /. neomexicana Felt, by the decidedly broader terminal clasp
