Female. Length 1.75 mm. Antennae about as long as the body, 

 rather thickly haired, fuscous yellowish ; 14 segments, the fifth with a 

 stem about one-fifth the length of the cylindric basal enlargement, 

 which latter closely resembles that of the male, though the irregular 

 circumfili are not so highly developed as in the opposite sex ; terminal 

 segment reduced, sessile, with a length about twice its diameter, ob- 

 tuse apically. The apex of the abdomen is expanded, bearing several 

 irregularly triangular plates and a moderately short, stout, crooked, 

 setose ovipositor with a distinct subapical enlargement. Other charac- 

 ters practically as in the male. Type Cecid. 32234. 



Mycodiplosis pulvinariae n. sp. 



Numerous larvae of this midge were found by Mr. W. H. 

 Sands, St. Vincent, W. I., preying upon Pitlvinaria pyriformis, 

 and the midges reared therefrom were submitted to us through 

 the courtesy of Mr. William H. Patterson of the Agricultural 

 School. The species is allied to M. coccidivora Felt, though 

 easily distinguished by the much stouter basal clasp segment 

 in the male and the rather closely spined terminal lobes of the 

 female. 



Larra. Length 1.5 mm., yellowish, moderately stout, tapering slightly 

 at both extremities and without a visible breastbone. 



Pupa. Length 1.5 mm., salmon-colored, moderately stout. Thoracic 

 horns filiform. Wing cases extending to the second abdominal seg- 

 ment, the anterior and mid-leg cases to the fourth, and the posterior 

 leg cases to the fifth abdominal segment. 



Male. Length i mm. Antennae one-fourth longer than the body, 

 rather thickly haired, fuscous yellowish; 14 segments, the fifth having 

 stems with a length one-half and one-fourth greater than their diam- 

 eters, respectively; distal enlargement pyriform, with a length one- 

 fourth greater than its diameter; circumfili moderately long, stout, 

 setae long, stout. Palpi : first segment subquadrate, the second with 

 r, length about thrice its diameter, the third and fourth a little shorter 

 than the second and successively more slender. Mesonotum dark 

 brown. Scutellurn and postscutellum yellowish. Abdomen fuscous 

 yellowish. Wings hyaline, costa fuscous yellowish. Halteres yellow- 

 ish. Coxae and femora basally yellowish, the distal portion of femora, 

 tibiae and tarsi mostly dark straw. Claws slender, strongly curved, 

 the anterior unidentate, the pulvilli rudimentary. Genitalia : basal 

 clasp segment rather long, slender; terminal clasp segment relatively- 

 short, stout; dorsal plate long, dri-ply and triangularly incised, the 

 lobes tapering and narrowly rounded apically ; ventral plate moderately 

 short, tapenng to a narrowly rounded apex.
