 on inner side, in the centre), scutellum (except at apex), 

 postscutellum, the keels, metanotum, the pleurae (except 

 the pro]ileura3 broadly in the centre), the first abdominal 

 seg-mont broadly in the centre, a narrower stripe down the 

 middle of the second (widest at the apex, not touching the 

 base or apex of the segment), and transverse lines before 

 the apices of the others, the apical two interrupted, and the 

 ventral surface, pale yellow. Legs pale yellow, the fore 

 femora behind, the middle above on the apical two thirds, the 

 posterior entirely above, the base of the tibiae, and the tarsi 

 black. Wings hyaline, the costa and nervures black, the 

 stigma fulvous ; pedicle of areolet shorter than lower branches, 

 the recurrent nervure interstitial. ^ . 



Length 18, terebra 21 mm.

Face closely but not coarsely punctured, thickly covered 

 with short white pubescence. Basal and apical slopes of 

 mesonotum smooth ; the striation strongest in front. Clypeus 

 depressed, yellow tinged with rufous. 



May be known from the described Lido-Malaj and 

 Lidian species by the immaculate wings. 



EjnrliT/ssa nigrohalteata^ Cam. 



Tiie markings on this Bornean species vary somewhat, 

 e. q. the yellow mark on the mesonotum may be longer than 

 wide, with a triangular incision on the apex. 



Epirhyssa curvimaculata, sp. n. 



Black ; the face, clypeus, inner orbits to the ocelli, the outer 

 narrowly above, broadly below, prothorax (except for a broad 

 band on the pleurte), a pyriform spot on the sides of middle 

 lobe of mesonotum, a longer one on the inner side of the 

 lateral lobes of mesonotum, straight on outer side, rounded 

 on inner and produced into a sharp point at the apex, scutellar 

 keels, basal two thirds of scutellum, metanotum (except for a 

 semicircular mark on apical half), an oblong mark below the 

 tegulge, united to an oblique large mark below it, extending 

 from the base to the apex, the metapleurae (except at the 

 base, the black basal spot having the part above the keel 

 larger than that below it), broad bands (rounded at the base) 

 on the basal two abdominal segments, the lines on the 

 following three broad and curved backwards in the middle, 

 those on the following two broad, curved and widely inter- 

 rupted in the middle, and the basal ventral segments, pale
