A NEW GENUS OF DIAPRIIDS FROM TEXAS. 



WILLIAM H. ASHMEAD. 



Recently I received from Mr. W. H. Long, Jr., of Austin, 

 Texas, several specimens of a Diapriid, bred by him from puparia 

 of a Dipteron, Ceratopogon sp., obtained from an abandoned ant's 

 nest under a stone. 



A careful examination of the specimens shows that both sexes 

 are represented and that they will form the type of a new genus 

 allied to the recently established genus Solenopsia Wasmann ; 1 

 but quite distinct in several particulars. At the request of Mr. 

 Long, it is here described to be incorporated by him in a paper 

 that will appear shortly. 



ADELIOPRIA, gen. nov. (Diapriidse). 

 The two genera may separated as follows : 



Females 2 



Males 3 



2. Antennae u-jointed, the funicle joints 2-7 transverse, the 8th joint quadrate, the 



club large cone-shaped, unjointed Solenopna Wasm. 



Antenna 12-jointed, the flagellum clavate, the funicle joints 6-9 moniliform, the 

 club fusiform, 3- jointed 4deliopria, n. g. 



3. Antennae 12-jointed; mesonotum without parapsidal furrows. 



Flagellum ending in a 3-jointed club Solenopsia Wasm. 



Flagellum filiform, sparsely, finely pubescent, tapering off at tip, joints 2-1 1 

 moniliform, the last joint small, oval Adeliopria, n. g. 



ADELIOPRIA LONGII, sp. nov. 



9 $ . Length, .8 to i mm. Polished, black, impunctate, the metapleurae 

 clothed with a pale pubescence ; the head and thorax with a few fine long 

 hairs ; the head transverse, the temples obliquely rounded off posteriorly ; 

 scape, mandibles and legs rufo-testaceous ; the legs in 9 a little the darker 

 with the sutures of trochanters, a dot on knees and the extreme apices of 

 tibiae yellowish ; in $ with the front and middle coxae yellowish, the scutel- 

 lum has a large fovea across the base, separated into two by a delicate 

 median carina at base. Metathorax wrinkled with a slight median spine at 

 base, just back of scutellum. Wings hyaline, subemarginate at apex, the 

 apices being cordate ; the venation as in Phcenopria and ciliate. Abdomen 

 oblong, smooth and polished, the second segment very large, occupying 

 most of the surface ; the petiole longer than thick, furrowed. Type : Cat. 

 No. 5715, U. S. N. M. (8 9 and 2 $ specimens) Host. Dipt.; Ceratopogm
