By E. p. Felt, Albany, N. Y. 



The two West Indian species described below were reared 

 by Mr. W. H. Patterson, of the School of Agriculture, St. 

 Vincent, and recently sent to the writer for determination. 



Asphondylia vincenti n. sp. 



This species was reared from the fruits of Jussiaea linifolia 

 and /. suifrutiosa, at St. \'incent, W. I. 



Male. Length 1.75 mm- Antennae nearly as long as the body, 

 sparsely short-haired, dark brown ; 14 sessile segments, the fifth with 

 a length about five times its diameter; circumfili distinct, very tortuous. 

 Palpi : first segment irregularly oval, with a length over twice its diam- 

 eter, the second slender, nearly three times the length of the first. 

 Mesonotum a nearly uniform slaty brown, the submedian lines sparsely 

 haired. Scutellum fuscous yellowish, postscutellum darker. Abdomen 

 sparsely haired dark brown. Wings hyaline, costa light brown, sub- 

 costa uniting therewith just before the basal half, the third vein 

 at the apex of the wing, the fifth just beyond the distal third, 

 its branch just before the basal half. Legs mostly a variable 

 fuscous yellowish, the tarsal segments being darker, except the yellow- 

 ish brown tibiae and first four tarsal segments of the posterior legs ; 

 simple claws rather slender, strongly curved, the pulvilli as long as the 

 claws. Genitalia ; basal clasp segment short, greatly swollen ; terminal 

 clasp segment short, swollen, bidentate apically ; dorsal plate divided, 

 the lobes narrowly oval and thickly setose apically ; ventral plate small, 

 apparently bilobed. 



Female. Length 2 mm. Color characters nearly as in the male. An- 

 tennae : the fifth segment with a length about five times its diameter, 

 the I2th with a length Y^ greater than its diameter, the 13th a little short- 

 er, the 14th flattened, subglobose. Palpi : the first segment with a length 

 nearly three times its diameter, the second slender, ^ longer ; posterior 

 tibiae and first four tarsal segments markedly lighter than in the male. 

 Ovipositor when extended about as long as the body, the acicula 

 slender, acute ; dorsal pouch moderate sized, the lobes thickly setose 

 and narrowly rounded apically. 



Pupa. Length 2 mm. Oval, stout, yellowish brown ; cephalic horns 

 moderately long, stout, the inner obhque margins finely serrate ; antennal 

 cases extending to the first abdominal segment, the w-ing cases to the 

 fourth and the leg cases to the sixth. Just below the base of the an- 

 tennae and on the venter there is a median, triangular, chitinous pro-
