9. — Li'iijrth l.S iiiiii. Polislied l)l;ick ; aiiteima' iiiid le^s brownish yellow, the 

 middle and posterior coxie hhick. the anterior and middle femora dusky, the 

 posterior femora black ; anteniup suhelavate, Ti-jointed, reaehiiifr nearly to the 

 middle of abdomen, the third joint slifjlitly shorter than the fourth, the terminal 

 joint beiiifj the longest and thickest. Head and thorax jiolished, subpubescent. 

 the puhescenee denser on face, cheeks and metathorax. Thorax with the i)arai)- 

 sidal furrows delicate, subolisolete anteriorly; there is a short median grooved 

 line posteriorly and a short faint line on the scapnlse ; the scntellum is minutely 

 rugose, bare, the fovese at base small, indistinct; mesopleura highly jiolished. 

 bare, with a groove near the posterior margin. The abdomen is one-third longer 

 than wide vertically, subcompres.sed, highly polished, black, although sometimes 

 brown or piceous at base; the third, fourth, fifth and sixth segments short, the 

 sheaths of the ovipositor being short and not i)rojecting above the dorsum. Wings 

 hyaline, the veins pale and delicate, the cubitus, areolet and cubital transverse 

 vein usually ngt at all develojied, although in some sjieciniens they can be de- 

 tected, but are exceedingly faint. 



The % has 15-jointed, honey-yellow antenna, the scape alone being dusk.v, the 

 third joint is straight and unlike all other Ceroptres, being without the usual 

 emargination ; otherwise it agrees with 9 . 



Described from one % and seven 9 specimens. The females were 



observed ^fay 20 ovipositing in the niidril) of a leaf of Quercus 



rubra.

This genns is at once distinguished from Ceroptres by the 9 hav- 

 ing thirteen distinct joints in the antennse, the usually connate suture 

 dividing the second abdominal segment is as distinct as the others 

 and very oblique, dividing the segment into two equal parts; the 

 head is large and wider than the widest part of the thorax, while 

 the posterior tibia has two distinct apical spurs. The % has 1")- 

 jointed antennie, the third joint being longer than the fourtli and 

 excised. The otlier characters agree with Ceroptres, except the 

 sheaths of the ovipositor are small tind do not project.

 legs brown, all coxse black, femora and posterior tibiai obfuscated; mandibles 

 brown. Head and thorax minutely punctulate, very slightly transversel.v rugu- 

 lose : parapsidal grooves delicate, but distinct, and with two short lines between 

 them anteriorly: scntellum rugose, the foveas at base, distinct; mesopleura 

 highly polished ; metatliorax short, abrupt, rugose, bicarinated. Abdomen ovate, 

 slightly compressed, haiilly iis long as the thorax, smooth, highly polished, the 

 segments very oblique, the petiole short, wrinkled. Wings hyaline, pubescent, 

 the veins pale brown, the radial cell and areolet closed, cubital cell partially 

 closed, the cubitus extending to apical margin.
