The species described below comprise some of the more interest- 

 ing forms recently submitted for study. This is especially true of the 

 remarkable J ohnsonornyia and the Camptomyia, the latter being the 

 only female representative of this genus we have seen. 



Campylomyza truncata Felt. 



Male. — Length i nun. Antennae a little longer than the body, thickly 

 haired, reddish brown; 14 segments, the fifth with a stem as long as the pyri- 

 form basal enlargement, which latter has a length twice its diameter, obtusely 

 rounded. Palpi ; first segment broadly oval, second quadrate, with a length 

 twice the diameter, third roundly quadrate, shorter than the second, the fourth 

 lA longer than the third, more slender. Mesonotum and scutellum dark 

 reddish brown, postscutellum and abdomen a little darker. Halteres yellow- 

 ish basally, fuscous apically. Legs mostly fuscous yellowish, the distal tarsal 

 segments darker ; claws stout, strongly curved, denticulate, the pulvilli as long 

 as the claws. Genitalia ; basal clasp segment very short, broad ; terminal clasp 

 segment stout and quadrately rounded apically ; dorsal plate short, broad, the 

 very short lobes obliquely truncate. Harpes stout, truncate, the distal margin 

 and latero-distal spines heavily chitinized. Type Cecid 1404. 



This species, near to C. fiavoscittata Felt and C. modcsta Felt, was 

 collected April 17, 1910, by Dr. W. G. Dietz, Hazelton, Pa. 



Corinthomyia gracilis, new species. 



Male. — Length 1.5 mm. Antennae extending to the 4th abdominal segment, 

 sparsely haired, dark brown ; 14 subsessile segments, the fifth with a stem 1/2 

 the length of the cylindric basal enlargement, which latter has a length nearly 

 twice its diameter and 4 or 5 short, stout whorls ; terminal segment reduced, 

 tapering, with a conical appendage apically. Palpi ; first segment broadly oval, 

 the second rectangular, with a length o\ er twice its diameter, the third Yz
