l.ength, I'.L'd mm., excluding ovipositor wliidi is exserf.ed for n Imigth alumt equal to 

 tliat ot the abdomen. Head not quite tui.-e longer than wide. Postinarginal vein longer than 

 the stigma], the latter long. 



Orange yellow, the posterior margin of the head, flagelhmi, all of abdomen except at 

 base, an hourglass-shaped marking dowTi nieson of pronotum and eephalie |,art of scutum (a 

 smaller end cei.halad; shaped like an inverted eggcup), a stri].e across apex of thorax (about 

 apex of scutellum), the teguls and a dot in a line longitudinally with them, cephalad (opposite 

 the apes of the eggcup-shaped marking), ,iet black; also the valve.s of the ovipositor. 

 Mandibles bidentate at apex (but 5-dentate), the antenii;c II jointed without a ring-joint, the 

 scape hemispherically dilated (foliaceously). Tliird aa.l fonitli funide joints subeqiral, longest, 

 longer than the pedicel which is subeipial to the distal fuuicle joint. Postniarginal "vein 

 longer than either marginal or stigmal. tlie latter shortest. Wings hyaline. Body glabrous.

new genus. 



Femiile: — Agreeing with Ctratfifolciis Mayr but tlii> anteniue are only HI jointed, tlie 

 cdiib L!-jointed, the last two funiele joints wider than long, no ring-.ioints; first fiiiiiide joint with 

 a sheath-like process. Mandibles bidentate, the appendage serrate. Marginal, stigmal and 

 liostmarginal veins sube(|ual. Spiracular fovea long, gougelike. Head somewhat longer tli.-iu 

 wide, without a tubercle. Ovipositor as long as the thorax and abdomen together. 



Male: — Differing from CmUosohiis n\ that the antenna! are only 4-jointed. Mandibles 

 strongly bidentate. 



Typi:: The following s]iei-ies. 



1. CERATOSOLENSIA FICOPHAGA m « .species. 



FiirmU: — Length, t.lill luiii. Fore wings very bi'oad. 



Shining black, the distal third of the abdomen and the head sufl'used with brown. Wings 

 hyaline. Legs yellow, the antenna- brownish, the scafie and peilicel darker. Koiirth fiinicle 

 joint longei^t. Body glabrous. Parapsidal furrows subol solete caiulad. X'erti'x and center 

 of face .yellowish. Pnuiotum [lubescent. Intermediate femur dusky i-entrally. 



Afalr: — Length, about ;i inui. .\plcrniis .-md normal for I lie siibfainily. 



Eich yellow, the head chestnut lunwii, tin' prouofutn bri>unisli. .Vnteniue and legs con- 

 colorous with the head and body rcs|ic(l ivcly but the fiuuu'r with extreme tip pale yellow: 

 the antenna! lie for nearly their entire length in what appears to be a closed canal; the first 

 .joint is stout, the second shortest, subequal in width to the two following, the third longest 

 but not much longer than the fourth and last which is somewhat longer than the first; the 

 second joint is only about two thirds the length of the first. Types re ex:nnined.
