NO. 2195. NEW SPECIES OF UYMENOPTERA—ROHWER. 173 



antennal joints, but decidedly shorter than the length of the third 

 and fourth antennal joints; antennae slightly tapering apically, the 

 third joint about one-fourth shorter than the fourth; niesoscutum 

 shining with sparse distinct punctures; scutellum sculptured like 

 the scutum but more finely so, not impressed; mesepisternum shin- 

 ing, reticulate, practically impunctate; mesepimeron sculptured like 

 the mesepisternum; sides of the propodeum finely, longitudinally 

 aciculate ; dorsal aspect of the propodeum rather coarsely, uniformly 

 granular, without an impressed line; dorsal and posterior aspects 

 not sharply separated; third cubital on the radius subequal in 

 length with the second on the same vein; legs rather feebly spined, 

 the longer calcaria on the posterior tibiae subequal in length with 

 the posterior basitarsus; pygidium one and one-fourth times as long 

 as the basal width, shining, with a few large, well-separated punc- 

 tures, truncate apically. Black; the first two abdominal segments 

 except the extreme base of the first rufous; calcaria and spines of 

 the legs ferruginous; wings hyaline, venation ferruginous; head 

 and thorax with dense gray pile; abdominal tergites one to four 

 with narrow apical band of silvery pubescence.

LARROPSIS GREENEI. new Kpecics. 



This species is related to divisa Patton, but may readily be sep- 

 arated from that species by the sculpture of the dorsal aspect of the 

 propodeum. 



Female. — Length 13 mm. Anterior margin of the clypeus rounded 

 medianly, emarginate laterall}'' with two obscure teeth, the outer one 

 larger apically, margin hardly depressed, gently, evenly, convex me- 

 dianly; the anterior portion of the median convexity shining with 

 large, well-separated punctures; sides of the posterior portion of the 

 median convexity finely, closely punctured ; front finel3% very closely 

 punctured except the median area from the anterior ocellus to the 

 bases of the antennae which has large, sometimes confluent punc- 

 tures; intraocellar area uniformly convex, without a median furrow; 

 postocellar depression reduced to a curved furrow; vertex with 

 large, separate punctures; posterior orbits punctured like the front; 

 space between the eyes at the vertex subequal with the length of the 

 second, third, and fourth antennal joints; antennae slender, scarcely 

 tapering apically, longer than the head and thorax ; third and fourth 

 joints subequal; anterior face of the pronotum finely granular; 

 scutum so closely punctured as to appear granular; scutellum slightly 

 convex, with a median furrow and with distinct, close, well-defined
