No.]202. GENERA OF THE ENCYRTINJE—ASBMEADr 375 



The proiiotum is distinct, not short, about two-thirds the length of 

 the mesonotum, the latter being twice as wide as long and somewhat 

 shorter than the scntellum. The front wings have a short marginal 

 vein which is only about twice as long as thick, or a little longer; the 

 stigmal vein is nearly twice as long as the marginal, while the post- 

 marginal vein is very much longer than the stigmal. Abdomen in 

 female conically pointed, somewhat longer than the head and thorax 

 united, with the ovipositor exserted, the sheaths being very broad. 



I. HEMENCYRTUS HERBERTII Ashmead, new species. 



Female. — Length, 2.8 mm. Dark blue ; collar, scutellum toward apex, 

 metapleura, and abdomen aeneous black; antennae, except three or 

 four apical joints, and the legs, except the coxne, brownish-yellow. Head 

 with sparse but distinct thimble-like punctures on forehead and along 

 the inner orbits; the scrobes form a distinct semicircular depression. 

 The mesonotum is smooth apparently, but with a strong lens one can 

 detect a vaguely defined or indistinctly impressed thimble-like punctua- 

 tion. Wings subhyaline; tegulie piceous, the subcostal vein yellowish, 

 while the marginal, stigmal, and postmarginal veins are brown. Abdo- 

 men a little longer than the head and thorax united, depressed or concave 

 above, carinate beneath; the ovipositor exserted to nearly one-third its 

 length, with very broad, compressed sheaths. 



Habitat. — Brazil: Chapada. (Herbert H. Smith collection.) 



47. COCCpPHOCTONUS Ashmead, new genus. 

 (Type, Coccophoctonus dactylopii Aslimead.) 



Form very broad and robust, resembling somewhat the genus P/i«?- 

 nodiscus Forster. The head is lenticular, wider than the thorax, with 

 very large oblong-oval eyes, the frons in consequence being rather 

 narrow but still with the thimble-like punctuation. The antennne are 

 very short, the flagellum being scarcely longer than the slender scape, 

 the club very large and distinctly longer than the short funicle, the 

 joints of the latter being very small, transverse or annular. The pro- 

 notum is short; the mesonotum fully twice as wide as long, shorter than 

 the scutellum and smooth or very indistinctly punctate. The wings, 

 unlike those in Phamodiscus, are hyaline, the marginal vein being 

 scarcely three times as long as thick, the stigmal vein longer than the 

 marginal, while the postmarginal vein is fully as long as the marginal 

 and stigmal veins united. The abdomen in outline is triangular, broadly 

 sessile, depressed, and much shorter than the thorax. 



The male resembles the female, but is much smaller, narrower, less 

 robust, with the head smaller and not broader than the thorax; other- 

 wise in antennal and venational characters it agrees with the female. 



K COCCOPHOCTONUS DACTYLOPII Ashmead, new species. 



Female. — Length, 1.4 mm. Robust, blue black, the abdomen aeneous; 

 sca}>e pale yellowish; all tibiae and tarsi, apical third of middle tibiae,
