This rather anomalous form evidently belongs to the Lasioptera 

 group though the somewhat stout, occasionally simple claws and 

 the produced antennal segments suggest an affinity with Asphon- 

 dylia. Members of this genus have the Lasioptera type of venation, 

 the fifth vein simple, and are easily separated from allied forms by 

 the free third and fourth antennal segments and the minute, Partic- 

 ulate palpi. The ovipositor is short. Through the courtesy of 

 Professor Kieffer, examples of the generic type, S. a t r i p 1 i c i s 

 Kieff., reared from enlargements of the stem of A t r i p 1 e x 

 h a 1 i m u s, have been placed at our disposal and the following 

 description is drafted therefrom. 



Stefaniella atriplicis Kieff. 



Female. Length 2 mm. Antennae extending to the base of the 

 abdomen; 12 segments, the first obconic, the second 

 subglobose, the third and fourth free, the fifth 

 cylindric, with a length two and one-half times 

 its diameter and sparsely clothed with short hairs. 

 Low circumfili occur at the basal and distal fourths 

 and are united on one side much as in the female 

 Asphondylia. Terminal segment produced, with 

 a length five times its diameter. Palpi; first seg- 

 ment slender, with a length three times its diam- 

 eter, the second somewhat dilated with a length 

 four times its diameter. Wings; subcosta unit- 

 ing with cost a at the basal third, the third vein 

 at the basal half, both thickly scaled, the fifth vein 

 joining the posterior margin at the distal fourth, the 

 sixth at the basal half. Claws rather stout, appar- 

 ently simple, the pul villi about half the length of 

 the claws. Ovipositor about half the length of the 

 abdomen, the terminal lobes long, narrowly oval 

 and thickly setose.
