arises from the third vein near its union with subcosta, branches near the 

 middle of the wing, the anterior fork joining the margin at the apex of the 

 wing, the posterior branch nearly midway betweeen the anterior fork and the 

 simple fifth vein, which latter unites with the posterior margin at the distal 

 fourth, the sixth near the basal half ; membrane rather thickly clothed with 

 relatively long hairs. Halteres dull fuscous yellowish. Coxae dull yellowish, 

 the femora basally yellowish straw, the distal portion fuscous yellowish ; tibiae 

 and tarsi darker ; claws stout, strongly curved, the concavity stoutly pectinate ; 

 pulvilli nearly as long as the claws. Ovipositor short, apparently biarticulate, 

 the first segment irregularly triangular, the second narrowly oval, both thickly 

 setose. 



Exuvice. — Length 1.5 mm., whitish transparent, the short antennal cases 

 moderately stotit, the wing pads extending to about the fourth abdominal seg- 

 ment, the anterior margin in particular being fuscous, the leg cases reaching to 

 the tip of the abdomen ; the thorax dorsally, and pleurae with a few scattering, 

 long, slender setae, the surface of the abdomen with numerous transverse lines 

 of microscopic denticalations. Type Cecid ai495a. 



The unique female described above was reared April 17, 1911, 

 from a jar containing maple leaves infested last year with the larva 

 of Cccidomyia occUaris O. S. It is possible that the insect developed 

 from the very slight amount of decaying organic matter brought in 

 with the sand. We are unwilling to believe that it is the parent 

 of the semitransparent larvse producing in midsummer the numerous 

 ocellate galls on soft maple leaves. 



Porricondyla dorsata, new species. 



Female. — Length 2.5 mm. Antennje nearly as long as the body, light brown, 

 sparsely haired; 12 segments, the fifth with a stem H the length of the cylindric 

 basal enlargement, which latter has a length four times its diameter ; terminal 

 segment produced, with a length nearly five times its diameter, irregularly 

 obtuse apically. Palpi : first and second segments subequal, each with a length 

 about three times the diameter, the third J^ longer than the second, the fourth 

 y2 longer than the third. Mesonotum almost black. Scutellum yellowish orange, 

 postscutellum yellowish brown. Abdomen reddish brown, the pleurae yellowish 

 orange, costa light straw. Halteres yellowish orange. Coxae and femora pale 

 straw ; tibiae and tarsi fuscous straw ; claws slender, evenly curved, unidentate, 

 the pulvilli a little shorter than the claws. Ovipositor lobes narrowly and irreg- 

 ularly oval, sparsely setose. Type Cecid a2349. 



The midge described above was taken by Mr. D. B. Young at 

 Dug Mountain in the Adirondacks, August 8, 1912. It is easily 

 separated from other American species of Porricondyla, having 12 

 antennal segments, by the longer stem of the fifth segment.
