and with nume/ous circumlilar loops. Palpi, first segment short, subquadrate, second 



narrowly oval, the third one half longer, more slender and the fourth longer than the 



third and more slender. Mesonotum reddish brown, scu- 

 tellum yellowish, postscutellum reddish yellow, abdomen 

 yellowish, wings hyaline, haltères whitish transparent, legs 

 mostly pale straw. Claws long, slender, rather strongly 

 curved, the pulvilli as long as the claws. Genitalia, basal 

 clasp segment moderately long, stout, terminal clasp seg- 

 ment short, broad, the apical margin weakly chitinized. 

 üorsal plate short, broad, broadly and roundly emargi- 

 nate, the lobes broadly rounded and sparsely setose. 

 Ventral plate indistinct. 



Female. Length 2 m.M. Antennae extending to 

 the fourth abdominal segment, sparsely haired, light 

 brown, 14 subsessile segments, the fifth with a stem 

 about one seventh the length of the basal enlargement, 

 which, latter has a length four times its diameter, 13th 

 segment with a length nearly one half greater than its 

 diameter, the 14th with a length one fourth greater than 

 its diameter. Palpi, first segment short, irregular, the 

 second with a length at least three times its diameter, 

 the third one half longer, more slender, the fourth one 

 half longer than the third, more slender. Mesonotum 

 reddish brown. Scutellum, postscutellum and abdomen 

 yellowisli, haltères whitish transparent, coxae yellowish,

 nal segment of the male sho- 

 wing its tronodose shape and

 trical circumfila. 



Pupa Length 1.5 m.M. Antennal cases extending to the base of the abdomen, 

 the antennal horns rudimentary, wing cases reaching to the third, the leg cases to the 

 sixth abdominal segment. Thoracic horns long, moderately stout, curved apically, the 

 dorsum of the abdominal segments with two or three transverse basal rows of moderately 

 large chitinous spines. 



Larva. Length 1.75 m.M. Moderately slender, yellowish orange, the breast- 

 bone bidentate, the lobes broadly rounded and the shaft rather slender. Skin coarsely 

 shagreened. 



Type Cecid. A 2099. 



There was in this lot also one specimen of the somewhat similar appearing 

 though very different, predaceous Lestodiplosis, the larvae doubtless praying 

 upon those of the true gall makers.
