DESCRIPTION OF SOME NEW GENERA IN THE FAMILY 

 CYNIPIDAE. 



BV WILLIAM II. ASIIMEAD, WASHINGTON, D. C. 



Subfamily iii AXACIIARINAE. 

 ACANTHAEGILIPS gen. nov. 



This genus is based upon a single speci- 

 men in the Herbert Smith collection, taken 

 by him at Chapada, Brazil. It is closely 

 allied to Xyalaspis Hartig, and Aegilips 

 Ilaliday, but is readily distinguished from 

 both by the very large erect spined scutellum, 

 the rugose mesonotum which is without par- 

 apsidal furrows, the /a«^ open radial cell, and 

 by the larger abdominal petiole. 



Acanthaegilips bfaziWensis sp. n. $. — 

 Length 2.4 mm. Black, shining; antennae 

 and legs brownish-yellow, anterior and mid- 

 dle femora, except at base and apex, brown, 

 hind coxae and femora, except at apex, and 

 hind tibiae, except at base, black; wings 

 hyaline, the veins brown. 



The head is perfectly smooth, highly pol- 

 ished; mandibles brownish-yellow, 3-ilentate, 

 the teeth black; antennae longer than the 

 body, slightly thickened at apex, 13-jointed, 

 the scape long, obclavate, as long as the sec- 

 ond flagellar joint, the first flagellar ioint be- 

 ing as long as the pedicel and scape imited, 

 the following joints to penultimate graduallv 

 shortening, the last joint as long as the two 

 preceding united. Mesonotum coarsely 

 irregularly rugose, without furrows. Scutel- 

 lum produced into a long erect acute spine 

 the length of the mesonotum. Metanotum 

 rugose with the pleura pubescent. Marginal 

 vein long, open along the fore margin, the 

 second abscissa of radius twice the length of 

 first. Abdomen subglobose, polished, the 

 petiole smooth.

Subfamily viii CYNIPINAE. 

 Phylloxeras gen. nov. 

 This genus is based upon Biorr/iiza rubinus 

 Gillette, which is quite distinct from Biorrhiza 



W'estwood, in having i3-jointetl, not 14- 

 jointed antennae, and by having only faint 

 traces of parapsidal furrows. 



It comes, however, quite close to the aga- 

 mous female of Trigonaspis Hartig, but the 

 scutellum is rounded, with indications of 

 foveae on either side at base, and without a 

 rim at ape.x. In Trigonaspis. the scutellum 

 is semicircular, without foveae at base and 

 bounded by a delicate rim posteriorlv. 



In Phylloteras the frons is shagreened or 

 coriaceous, the mesonotum subopaque or alu- 

 taceous, the antennae rather short, the third 

 joint a little longer than the fourth, joints 9 

 to 12 twice as long as thick, while the claws 

 of hind tarsi have a tooth at base within. In 

 Trigonaspis the frons is smooth, shining, or 

 at the most feebly alutaceous, the mesonotum 

 polished, the antennae with the third joint 

 almost twice as long as the fourth, joints 7 

 to 12 being scarcely longer than thick, while 

 the claws of hind tarsi are simple, without a 

 tooth. 



Sphaeroteras gen. nov. 



This genus is based upon Bioyihiza mellea 

 Ashm., which diflJers from the true Biorrhiza 

 in having no carina on the frons between the 

 antennae, in having only 13-jointed antennae, 

 by the scutellum being rounded, and finallv 

 by the hind tarsi being much shorter than 

 the tibiae, the claws having a more or less 

 distinct tooth beneath at base. 



In Biorrhiza the scutellum is lunate or 

 semicircular, the frons carinate, the hind tarsi 

 as long as their tibiae, while the claws are 

 simple. 



Trichoteras gen. nov. 



In this genus the antennae are only 12- 

 jointed, the third joint being a little shorter 

 and thicker than the fourth, but of an equal
