Prosopis digitata Ckll. 



One S , June 29, 1902, Potentilla (pulcherimum) ? (Viereck). 



Prosopis nucleolus n. sp. Disc of metathorax rugose, with no large 

 shining pits, abdomen impunctate. 



9 Length 6 mm. — Clypeus, sides of face and supraclypeal area sericeous in 

 certain lights, opaque. The clypeus finely roughened and with sparse indistinct 

 punctures. Sides of the face and supraclypeal area very finely striate. Front 

 dull, finely rugulose except on the extreme sides where it is more shining, sparsely 

 indistinctly punctured. The median line not well marked. The narrow frontal 

 fovese starting on a line with top of the eye, extend half way down the front, 

 parallel with and close to the eye margin. Occipital region and cheeks dullish, 

 indistinctly punctured. First front of flagellum distinctly longer than the second, 

 a little longer thau the third. Dorsulum covered with close shallow punctures, 

 opaque, the median line extending half way back. The lateral lines short and 

 indistinct. Sides of the mesothorax opaque, the shallow punctures more sepa- 

 rated than those on dorsulum. Tegulse with a few punctures on the anterior 

 half. Metathorax with a well defined area, its surface rugose somewhat shining, 

 the lower third opaque, finely roughened like the adjoining areas. Metapleuras 

 delicately pitted. Wings hyaline with a grayish tinge, second transverse cubitus 

 curved, the second submarginal cell a little longer on the radius than it is broad 

 on the first transverse cubitus. Abdomen shining, apparently impunctate, the 

 first segment polished. 



Black. A narrow bow shaped yellow mark on each side of face separated from 

 the clypeus, extending along the eye margin, the lower point almost ou a line 

 with the lower margin of the eye, the upper point slightly directed away from 

 the eye margin and on aline with insertion of antenna. A well marked line on 

 each side of pronotum, greater part of tubercles and basal third of posterior tibiae 

 yellow, the maculation is of a lemon yellow color. 



Type, Coll. Acad. Nat. Sciences Phila. Type locality, Beulah, 

 N. M., May 30, on Salix (W. P. Cockerel!). In Cockerell's tables,

Prosopis jenigiUU!* n. sp. — Disc of metathorax rugose, with no large 

 shining pits as in episcopalis to which it is related in the face marks, abdomen 

 punctured. 



% Length 4 mm. — Clypeus dullish and with shallow well separated punctures, 

 the lateral face marks with closely arranged indistinct punctures. The supra- 

 clypeal mark with smaller deeper punctures than on the margins of the clypeus. 

 Front almost uniformly closely punctured. Clypeus twice as long as broad at 

 apex. The vertex punctured like the front, the cheeks not so strongly punctured, 

 shining. First joint of flagellum distinctly shorter than the second. The lateral 

 fovese of front indistinct, close to the eye margin. Mesonotum with closely ar- 

 ranged distinct punctures, those of scntellum larger more separated. Mesopleurge 

 not so closely punctured as dorsulum. Enclosure of metathorax not so distinct, 

 the adjoining areas rugulose. Metapleurre shining, indistinctly sculptured. Wings 

 tinged with gray, second transverse cubitus almost straight, the second cubital 

 cell a little shorter on the radius than it is broad on the first transverse cubitus.
