Hormomyia shawi sp. nov. 



This midge was received from C. W. Johnson of the Boston 

 Society of Natural History and labeled: "VIII-20, 1909 Hampton, 

 N. H., S. A. Shaw 1187." It is allied to H. consobrina Felt, from 

 which it is easily separated by coloration and the extremely 

 slender second palpal segment. 



Male. Length, 3.5 mm. Antenme as long as the body, thickly haired, pale 

 yellowish; 15 segments, the fifth having the stems with a length one-half and one- 

 fourth greater than their diameters, respectively. The distal enlargement sub- 

 cylindric, with a length fully half greater than its diameter; terminal segment 

 rudimentary, subglobose. Palpi; first segment stout, with a length about twice its 

 width, the second extremely long and slender, it having a length more than 10 

 times its diameter. Mesonotum light yellowish orange, submedian lines indistinct. 

 Scutellum and postscutellum yellowish orange. Abdomen thickly haired, pale 

 yellowish, the basal segment and genitalia yellowish orange. Wings hyaline, costa 

 light straw. Halteres yellowish basally, fuscous apically. Coxae yellowish orange; 

 legs a nearly uniform dark straw; claws slender, evenly curved, the pulvilli rudi- 

 mentary. Genitalia; basal clasp segment narrowly oval; terminal clasp segment 

 moderately short, stout; dorsal plate broad, roundly and triangularly emarginate, 

 the lobes broadly and irregularly rounded; ventral plate long, broad, subtruncate, 

 slightly emarginate, both sparsely setose. Type: Cecid. 1423. 



Hormomyia modesta sp. nov. 



This species was taken at Auburndale, Mass., May 22, by Mr. 

 C. YV. Johnson of Boston. It may be recognized by the dark 

 brown abdomen and the fourteen cylindric antennal segments, 

 the fifth with a length two and one-half times its diameter and 

 with three circumfili. 



Description. Female, Length, 4 mm. Antennae sparsely haired, fuscous yel- 

 lowish; fourteen segments, the fifth cylindric, with a length tw r o and one-half times 

 its diameter; sparse whorls 6f stout setae occur basally and at the distal third; there 

 are low' circumfili near the basal third, the middle and apically; terminal segment 

 slightly produced, with a distinct knob apically. Palpi; first segment short, 

 second with a length three times its diameter, the third a little longer than the 

 second, tapering. Mesonotum smooth, reddish brown, the yellowish submedian 

 lines narrow. Scutellum pale yellowish, postscutellum yellowish, dark brow r n 

 basally. Abdomen a nearly uniform shining dark brown; ovipositor pale orange; 

 venter concolorous. Wings hyaline. Halteres yellowish basally, fuscous apically. 

 Coxae, femora and tibiae mostly a light fuscous yellowish, tarsi fuscous yellowish or
