1. CHROMEURYTOMA CLAVICORNIS C.vmcron. Fcmal,.. Onotyp... 

 Length, 4.5 niui.

Vertex belo^Y the ocelli finely, rlnsely str,afe,|; aj.ex of jironotnin, niesonotum and 

 sentelhun finely, closely striate.l, the striatnni stronger o„ the snitellnni, weaker on the base 

 of mesonotnm; post^-utellnni niicroscopieally striated, the parts liordering it fiery-red. 

 .\tetanotum smooth. Metapleiira^ fiery-red. Abdomen snmoth. .\pex of pronoliim narrowly 

 fiery-red. There is a wide enrved furrow on the malar space. Ventr.al surface of the alidomen 

 largely violaceous.

" Submarginal vein twice the length of the marginal, thickened toward a|iex, marginal 

 tliickeued, postniarginal not one half the length (]f marginal, not longer than stigmal, w'^hich 

 is triangularly thickened at base, at its .iuncti<m with the irmrginal, the lower part of it 

 narrowed, roundly curved. Antenna' U-jointed, short, thick, .ji>ints of tlagellum wider than 

 thick, not distinctly separated, at the most only pilose; the scape n.arrnuer than fiagellnni and 

 does not extencl nundi above the middle of the eyes; there is no clear .dull to the antenna'; the 

 front is not much de])ressed. 



Ocelli almost in a straight line, the central very little in front of the lateral. X^arapsidal 

 furrows clearly defined, roumled. meeting very shortly before base of scutellum. Scutellnm 

 large, longish-iiyriforn,, the broad end at the .apex; almost as long as the niesonotum. 

 Metanotum short, steeply oblique; the centre with a, keel on one side, the tw-o parallel, not 

 converging. Thorax not punctured, only very finely striateil above. Abdomen sessile, distinctly 

 shorter than thorax; its second segment much longer than the others; its apex bluntly 

 rounded, broad; fifth segment shorter than fourth. 



Comes near to Xcinthosomti Ashmead which may be known from it by the fifth 

 abdominal segment in the female being nearly twice as long as the fourth, by the abdomen 

 being longer than the tliorax, and by the marginal vein being one and a half times, not twice 

 longer than the stigmal. The partipsidal furrows are deeper, more clearly defined and more 

 roundly curved than in Eiinitoiiiii : the siutellum is larger and much nmre narrowed at base 

 than in that genus. 



1. XANTHEURYTOMA FLAVA (;ai.ic.r<.n. ilale. Cenotype. 



Length, 2 mm. 



''Yellow-; ba<-k of thorax deejier, more fulv(.)us in tint; centre of the whole of btisal slope 

 ■of prouotum and the thoracic sutures more or less black, tlagellum of antennae tinged with 

 fulvous, legs a paler yellow than the liody; wings hyaline, nervures testaceous, the dilated 

 parts darker colored; stigmal vein triangidarly dilated at base, the apical part a little longer 

 than it, roundly curved. The metanotum and back of abdomen may be infuscated. 



Occiput transverse, infuscated, more or less ol srurely striated. Hinder ocelli sejiarated 

 from each other by twice the distance they are from the eyes. Mesonotnm ami scutellnm finel_v, 

 closely, transversely striated. Parapsidal furrows distinct, roundly curved toward each other 

 at apex, where they unite and are .joined to the scutellar furrow by a short one. Scutellum 

 large, ovate, twice longer than wide, obli<|uely narrowed to a point at the b.-ise. the apex broadly 

 rounded. 



Probably a variable species, as regards the amount of black.'' 



Probably a Taneostigmine.
