10 Psyche [February 



out, or with a very short, hair-fringe; marginal vein attaining the basal-third of the 

 wang, the stigmal vein swollen, oblique, more or less wedge-shaped. Legs rather 

 short; tibial spurs very short. 

 Type: X cf. opaca sp. nov. 



This genus seems to be most closely related to Acanthopria Ash- 

 mead represented in the West Indian Islands, differing, however, 

 in having only eleven antennal joints. Only three other genera 

 in the family have 11-jointed antennae, Notoxopria, Solenopsia, 

 and Doliopria and none of these are closely related to the present 

 genus. 



Xanthopria opaca sp. no\-. 



9. Length 1.6-1.7 mm. laght fuscous, head piceous below the antennae and 

 about the ocelli; abdomen blackened along the sides and at apex; legs and antennae 

 considerably lighter than the body. Ocelli close together in a triangle the pos- 

 terior pair a little farther from the eye-margin than from one another; vertex 

 strongly elevated at the ocelli, the front with a vertical grooved depression between 

 them and the antennae; eyes ovate, rather small, with large facets, acute below; 

 face shghtly convex, the small clypeus protuberant; entire head closelj', minutely 

 rugose, opaque, except for a subshining area on the cheeks; antennae nearly as long 

 as the body, 11-jointed; scape as long as the four following joints together; pedicel 

 cylindrical, as long, but thicker than the second flagellar joint and three-fourths as 

 long as the much more slender first flagellar joint; third and following joints of 

 flagellum about equal, but becoming thicker, the club very gradual, but rather 

 distinctly 6-jointed, its joints except the last nearly quadrate. Mesonotum with- 

 out parapsidal furrows, its posterior margin straight; scutellum with a large trape- 

 zium-shaped depression at the base to each side of which lie the axillae and behind 

 which lies the convex, roimded-quadrate body of the scutellum; scutellum behind 

 with a short median carina; post-scutellum unarmed; metanotum with a median, 

 blunt spine at the extreme base; the lateral and posterior margins raised and the 

 posterior angles slightly projecting; entire mesonotum, axillae, scutellum and pro- 

 pleurae finely rugose, opaque; mesopleura shining except above; metapleurfe finely 

 rugulose, shining, with a deep circular impression above, clothed with sparse wooly 

 hairs above. Abdominal petiole as long as broad, a little narrowed basally, with 

 sparse wooly hairs above; second .segment occupying three-fourths of the abdomen, 

 widest at the middle, wath arcuate sides, smooth and highly polished; third seg- 

 ment short; others scarcely visible. Legs rather stout, tibial spurs minute. Ante- 

 rior wings short and broad, distinctly brownish especially on the anterior half, en- 

 tirely without hair-fringe; submarginal vein one-third of the wing length, gradually 

 thickened before the short, stout, obHque stigmal vein; hind wings with a long fringe 

 on the posterior edge.
