 scutellum, postscutellum, and sides of the median segment broadly, 

 and transverse bauds on the posterior margins of all the abdominal 

 segments, yellow ; on the basal two segments the transverse band 

 joins on laterally to large roundish yellow spots ; in some specimens 

 these spots are free, not joined to the transverse baud ; legs yellow, 

 the coxa) and base of the femora black : wings hyaline and 

 iridescent, slightly fuscesceut along the costal margin and in the 

 apex of the radial cell of the fore wing ; 2nd cubital cell much

$ . Closely allied to and resembling 0. oralis. The type speci- 

 men in the British Museum, which is the only one I have seen, 

 differs from 0. ovcdis in having the occiput and cheeks more 

 developed posteriorly, the occiput especially being transverse, not 

 roundly emarginate as in ovcdis. Black; the base of the mandibles, 

 the clypeus, a wedge-shaped spot above it on the front, a line on 

 the inner orbits joining a spot in the emarginatiou of the eyes, the 

 scape of the antennae, a broad line behind the eyes, a large spot on 

 each side of the pronotum meeting in the middle, the tegulse, 

 tubercles, scutellum, the middle of the postscutellum, an ovate 

 spot on each side of the median segment, a line broadest in the 

 middle on the 1st abdominal segment, the posterior margins 

 broadly of the 2nd-4th segments, and a square spot in the middle 

 of-the 5th segment, yellow ; there is a round yellow spot at the base 

 of the 2nd segment, joined by a narrow line to the band on its 

 margin ; legs yellow, the coxae, trochanters, and base of the femora 

 black ; wings hyaline, brownish yellow along the costal margin of 

 the fore wing, and with a fuscous cloud in the radial cell.

§ . Head and thorax coarsely punctured, the punctures running 

 into reticulations on the median segment, on the front and clypeus 

 they are rather shallow ; abdomen more sparsely and finely 

 punctured ; clypeus at apex slightly bidentate, scutellum with a 

 medial longitudinal broad furrow, postscutellum not truncate 

 posteriorly ; median segment deeply emarginate posteriorly, the 

 sides produced obtusely, the truncation smooth and finely, obliquely 

 striate. Black, the abdomen in certain lights with a cinereous 

 silvery pile ; the base of the mandibles, a line on each side of the 

 clypeus at base, a spot and a medial vertical line above the base of 

 the antennae, a spot in the emarginatiou of the eyes, a line behind
