ART. 15». REVISION OF SUBFAMILY PLATYGASTERINAE FOUTS. 129 



tinotly (but not greatly) more than twice as wide as long, seen from 

 above its front and hind margins approximately straight; frons with 

 a beautiful fine shagreening, with a small shallow impression medi- 

 ally ; vertex and occiput fiinely shagreened , the former bounded poste- 

 riorly by a low but sharp carina; "funiole slender, the second joint 

 longer then the first, the third and fourth small, but a little thicker 

 than the second; club 4-jointed, the joints, except the last, as wide 

 as long; "relative proportions of the thorax as follows: length 28, 

 width 21, height 24; mesonotum and pronotum shagreened ; niiesono- 

 tum highly elevated posteriorly, densely pubescent on either side of 

 the median lobe which is abruptly curved downward; scutellum as in 

 flavicornis but the tubercle more in evidence, directed upward; abdo- 

 men elliptical, slightly narrower and longer than the thorax, not quite 

 two-thu'ds as wide as long, without sculpture of any sort; second ter- 

 gite a trifle longer than wide; following segments broadly transverse, 

 the terminal one triangular, nearly as long as the three preceding 

 united, polished; wings hyaline, somewhat whitish, the anterior ones 

 without marginal cilia. Black; antenna, except club, brownish yel- 

 low; club brown-black; mandibles and legs, except coxae and middle 

 and posterior femora, reddish yellow; coxae and femora, except the 

 anterior ones, dark brown. 



Type locality. — JaJcksonville, Florida. 



Type.— C&t. No. 2861, U.S.N.M. 



Redescribed from the type specimen. The male specimen men- 

 tioned by Ashmead belongs to a new species. I do not describe it 

 because I believe that species based on single specimens as types are 

 undesirable in this difficult group. 



17. LEPTACIS GLOBATA, new species. 



Plate 2, figs. 12, 13. 

 Female. — Ijength 1.1 mm. Very closely related to cynipsiphila. 

 It differs from my description of that species as follows: frons without 

 a median impression; ridge between vertex and occiput very high and 

 sharp; antennae as shown in figure; thoracic ratio: length 23, width 

 16, height 19; protuberance of mesonotum perfectly circular, evenly 

 convex, polished, not abruptly turned downward posteriorly; area to 

 either side of the protuberance not conspicuously pubescent; scutel- 

 lum transverse, densely pubescent; spine as in Jlavicornis : abdomen 

 0.57 mm. long, elliptical, four-sevenths times as wide as long, sharply 

 pointed apically; second tergite as wide as long, polished, without 

 sculpture; following tergites also without sculpture, the three follow- 

 ing the second subequal in length, becoming abruptly narrower poste- 

 riorly; sixth tergite slightly longer than the three preceding, triangular, 

 much broader at the base than long: middle and hind femora, and 

 hind tibiae, stramineous; coxae black.
