its diameter. Palpi : first segment irregular, with a length twice its diameter, 

 the second a little longer, irregular, the third longer than the second, more 

 slender, the fourth ^ longer than the third. Mesonotum reddish brown, the 

 submedian lines yellowish. Scutellum and postscutellum yellowish. Abdomen 

 reddish orange, the genitalia fuscous yellowish. Wings hyaline, costa light 

 straw. Halteres pale yellowish, slightly fuscous subapically. Coxae and legs 

 a nearly uniform fuscous yellowish. Claws slender, evenly curved, simple, the 

 pulvilli Ys the length of the claws. Genitalia : dorsal plate short, deeply and 

 narrowly incised, the lobes narrowly rounded and sparsely setose apically ; 

 ventral plate long, expanded distally, broadly and roundly emarginate, the lobes 

 plainly slender and tapering distally. 



Female. — Length i mm. Antennae extending to the fourth abdominal seg- 

 ment, sparsely haired, fuscous yellowish; 14 segments, the fifth with a stem Vs 

 the length of the slender basal enlargement, which latter has a length 254 times 

 its diameter ; terminal segment produced, with a length four times its diameter 

 and apically a stout, fusiform process nearly as long as the basal portion. 

 Palpi : first segment irregular, the second broadly oval, with a length yi greater 

 than its diameter, the third a little longer, slender, the fourth fully H longer 

 than the third, more slender. Face yellowish. Mesonotum dark brown, the 

 submedian lines yellowish. Scutellum and postscutellum yellowish. Abdomen 

 yellowish orange. Ovipositor short, the terminal lobes narrowly oval, with a 

 length over twice the diameter and sparsely setose. Type Cecid a23i6a. 



The small midge described above was reared in some numbers 

 July II, 1912, from apple leaves infested by the rosy aphis, Aphis 

 malifoUa Fitch collected at Nassau, N. Y. This species was more 

 numerous than an associated larger form, probably an Aphidoletes. 

 It may be separated from the allied /. sanguinia Felt by the yellowish 

 orange abdomen, the stems of the 5th antennal segment being equal 

 and the fourth palpal segment a little longer than the third. 

 Itonida putrida, new species. 



Male. — Length 1.5 mm. Antennae % longer than the body, thickly haired, 

 yellowish brown, yellowish basally ; 14 segments, the fifth having the stems as 

 long and H longer than their diameters, respectively ; distal enlargement with a 

 length ^^ greater than its diameter; terminal segment produced, the distal en- 

 largement broadly fusiform, with a length twice its diameter and a short, 

 stout knob apically. Palpi : first segment subquadrate, the second a little longer, 

 stouter, the third a little longer than the second, more slender, the fourth ^ 

 longer than the third, dilated. Mesonotum slaty brown, the fuscous yellowish 

 submedian lines sparsely haired. Scutellum fuscous yellowish, postscutellum 

 reddish brown. Abdomen yellowish orange, the terminal segments dark car- 

 mine. Genitalia fuscous yellowish. Wings hyaline, costa light straw. Hal- 

 teres yellowish basally, reddish apically. Coxae and femora mostly fuscous yel- 

 lowish ; tibiae somewhat darker, tarsi dark straw ; claws evenly curved, the pul-
