mark in the centre of the proplenrrc below, a longish oval 

 mark on tlie opex of the middle lobe of mesonotum, tegulse, 

 scutellum (except at apex), a small spot on the sides near the 

 apex o£ the yellow part and united to it, scutellar keels, a 

 band on the base of metanotum, the black bordering its apex, 

 4-lobate, a large trilobate mark on apex, the central lobe 

 projecting backwards, smaller than the others, its base incised 

 in the middle, the sides rounded, a broad large mark, the 

 base roundly dilated, the apex straight, produced posteriorly 

 below, this part being also produced backwards as a broad 

 line to near the apex of the basal third on mesopleurse, the 

 centre of mesosternum broadly, the mark widened towards 

 the apex and with a black mark in the middle of the apex, 

 a small mark under the hind wings, a large one almost 

 covering the metapleurte, a broad mark on the apex of the 

 first abdominal segment, its basal half narrowed, rounded 

 and incised at the centre, narrower lines, dilated laterally, on 

 the apices of the second to sixth, the seventh (except for a 

 large trilobate mark), the apical lobe square, larger than the 

 lateral, and the ventral surface (except the first and large marks 

 on the following three segments), pale yellow. Antennae 

 broadly (sixth to twelfth joints) ringed with white. Legs 

 yellow, the anterior paler, the hinder femora fulvous ; a spot 

 on the outer apical side of the four anterior, the posterior 

 below and broadly at the apex all round, a line on the 

 trochanters, on the four anterior femora, the apex of the 

 hind femora narrowly, the base of the hind tibite slightly 

 more broadly, the apex of the hind tibiae more broadly, and 

 the apical joint of the tarsi, black. Wings hyaline, the 

 nervures and stigma black. 

 Length 19, terebra 5 mm. 

 Quop, Sarawak; November (Heicitt). 

 Closely punctured, densely covered with short white 

 pubescence ; the mesopleuraa at the base closely striated ; the 

 depressed apex of middle lobe finely longitudinally striated. 

 Base of metanotum behind the keel closely, somewhat 

 strongly striated, the part between the two keels stoutly 

 closely striated in the middle, the sides closely reticulated, 

 the apex much more strongly striated, the stri» curved ; the 

 basal keel curved backwards in the middle, the apical stouter, 

 not curved in the middle. Parapsidal furrows distinct, 

 narrow, deep. The first abdominal segment broadly smooth 

 in the centre of narrowed basal part, this smooth line 

 bifurcating on the widened apex ; the punctures on the 

 segment are stronger and more widely separated than on the 

 rest of the abdomen. Areolet as long as it is wide at the base,
