the legs mostly dark brown ; claws simple, curved at nearly right angles, greatly 

 swollen subapically, the pulvilli about as long as the claws. Genitalia : basal 

 clasp segment with a large triangular basal lobe internally ; terminal clasp seg- 

 ment long, stout, slightly swollen basally ; dorsal plate short, broadly and tri- 

 angularly emarginate and mesially with a moderately deep, narrow incision ; 

 ventral plate long, broad, tapering, broadly and roundly emarginate ; style 

 long, stout. 



Female. — Length 2 mm. Antennae nearly as long as the body, sparsely 

 haired, fuscous yellowish ; 14 segments, the fifth with a stem ^ the length of the 

 cylindric basal enlargement, which latter has a length thrice its diameter; 

 terminal segment produced, the basal enlargement with a length five times its 

 diameter; apically there is a slender, hairy process about % the length of the 

 enlargement. Palpi : first segment irregularly subquadrate, the second with a 

 length three times its diameter, the third a little shorter, the fourth i<2 longer 

 than the third. Mesonotum yellowish brown, the submedian lines sparsely 

 haired. Scutellum pale orange, postscutellum yellowish. Abdomen yellowish 

 orange. Wings hyaline, costa light straw. Halteres yellowish basally, fuscous 

 apically. Coxse yellowish, the legs mostly dark brown, the distal tarsal segments 

 especially on the anterior legs, yellowish brown. Ovipositor short, the terminal 

 lobes with a length nearly twice the diameter, broadly rounded apically. Type 

 a22ig. 



Two males were reared June 3 and 4, 1912, from fruit of Duli- 

 chium arundinacenm infested by an orange-colored larva some 2 mm. 

 in length and collected in August, 1911, by Miss Cora H. Clarke, 

 Magnolia, Mass. The species is exceedingly interesting because of 

 the extremely short circumfili, the produced distal enlargement and 

 the gradual transition from the binodose to a cylindric stemmed con- 

 dition in the distal antennal segments. It is allied to T. inosellana 

 Gehin and T. hudsonici Felt, from which it may be separated by the 

 moderate length of the basal portion of the stem of the 5th antennal 

 segment. A species of Lestodiplosis was also reared from this 

 material.

The development of the gall is extremely interesting, as evidenced 

 by material received from Marksville, La., from Dr. W. L. McAtee 

 under date of September 12, 1912. The galls appear to originate in 

 small, globose or oval, densely pruinose swellings having rudimen- 

 tary leaves and near the tips of the smaller, tender shoots. These 

 enlargements vary in length from 5 to 8 mm., they are spongy, the 

 green interior containing a variable number of yellowish larvae 

 grouped along the central axis much as in the mature, more familiar
