above and also deflected inward from the margin of the eye, posterior 

 orbits, posterior border of pronotum, sides of prothorax and tubercles 

 except irregular elongated spot in front of the latter, spot on tegulae, 

 small lateral spot on scutum above base of wings, triangular lateral 

 spots on scutellum, curved fascia on metanotum, lateral angles, con- 

 tinued in form of spot on sides of median segment, small spot at 

 spiracles on same, spot on metapleurae, spot on mesopleurae elon- 

 gated vertically, broad fasciae on tergites 1-5, the first slightly 

 attenuated and narrowly interrupted medially, remainder continu- 

 ous, biemarginate anteriorly and triangularly notched at the middle 

 on posterior border, pair of spots on sixth and seventh tergites, 

 broad fascia on second sternite, fascia on third broadly and deeply 

 biemarginate on anterior border, fascia on fourth similar to that on 

 third but with anterior emarginations much enlarged, lateral spots 

 on fifth and sixth, spot on coxae below, femora except short basal 

 markings, tibiae, and tarsi, yellow. Marks on scutellum and meta- 

 notum are nearly white. 



The flagellum is simple, neither dentate nor spinose, but segments 

 5-11 on the posterior surface bear shallow pits. The ultimate seg- 

 ment is very slightly curved and rounded at the apex. The middle 

 femora are smooth and the posterior pair is provided with long white 

 pubescence below. The second sternite bears a prominent hooked 

 process and the seventh a prominent median process, triangular in 

 form, obliquely directed backward, broad at base, flat on the ventral 

 surface, and bluntly pointed at the apex. 



Female. — Black: Labrum, mandibles except apices, narrow apical 

 border and lateral apical angles of clypeus, spot between antennae, 

 spot in front of anterior ocellus and a small rounded spot on either 

 side of this one, anterior orbits deflected inward from the margin 

 of the eye above, posterior orbits, prothorax almost entirely, lateral 

 lines on scutum, pair of anterior longitudinal and a posterior trans- 

 verse discal mark on scutum, fascia on scutellum, broad laterally, nar- 

 row medially, fascia on metanotum, broad curved fascia on dorsum 

 of median segment extended downward medially on its posterior 

 surface, sides of mesothorax and metathorax and median segment 

 almost entirely, broad continuous fasciae on tergites 1-5, first emar- 

 ginate on posterior and anterior middle, second and third each inclos- 

 ing a pair of elliptical dorsal black spots, fourth and fifth each with a 

 pair of anterior emarginations corresponding to the black spots of 

 the preceding segments, ultimate tergite with a pair of apical spots, 

 lateral spots on sternites 1-5 connected by apical lines, the one on 

 second sternite broad and inclosing black spots, spot on coxae, femora 

 except basally and stripe on anterior pair above, tibiae, and tarsi, 

 yeUow.
