 face broad, slightly narrowed above ; clypeus short, very broad, flat, the side lobes 

 touching the eyes, the middle lobe somewhat prolonged and rounded at tip, un- 

 armed; a transverse ovate spot on each lobe of clypeus, broad longitudinal spot 

 on sides of face not reaching summit of eyes and broad line on prominence between 

 antennae, the whole forming three broad stripes on the face, line on upper posterior 

 orbits broader above, upper posterior margin of prothorax, postscutellum, two large 

 irregularly shaped spots on metathorax pointed within, tegulse, segments 1—5 of 

 abdomen above, except basal margin and transverse line on disk of segments three 

 and four, spot on sides of sixth segment, and interrupted bands on ventral seg- 

 ments 3 — 5, all lemon-yellow ; mandibles except tips, four basal joints of antennse, 

 basal half of flagellum beneath, legs entirely, and two basal segments of abdomen 

 beneath, fulvous-yellow; basal enclosure of metathorax densely and strongly 

 punctured ; wings hyaline, with costal margin irregularly clouded with yellowish- 

 fuscous, neuration as usual; segments 2 — 5 of abdomen above less densely and 

 more irregularly punctured, except in the transverse median 'deeply impressed 

 lines; apical segment finely rugulose above with lateral carina sharp, fringed 

 with pale hair and terminating in a short obtuse tooth; venter sparsely punc- 

 tured, shining. Length .50 inch. 



£ . — Black, opaque, densely and strongly punctured, clothed with whitish 

 pubescence ; head large, much wider than thorax ; face very broad, flat, very 

 slightly narrowed above, the tubercle between antennae prominent ; clypeus flat, 

 very broad, its anterior margin truncate its entire width, unarmed, the side lobes 

 touching the eyes for a short distance: mandibles with outer face dilated, flat- 

 tened, smooth, polished, the upper and lower edges obtusely angular, each mandi- 

 ble with a prominent and obtuse tooth within between base and apex, which 

 latter is pointed and subacute; face, clypeus, prominence between antennas, spot 

 or line behind summit of eyes, mandibles except tips, scape beneath, posterior 

 margin of prothorax, postscutellum, sometimes a dot on extreme sides of scutellum, 

 a small round spot on sides of metathorax above near base, tegulse, spots on thorax 

 beneath, coxae, trochanters, legs beneath, band on posterior margin of abdominal 

 segments 1 — 6 above, those on 2 — 5 more or less suddenly dilated laterally, and 

 bands on ventral segments 2 — 5, all lemon-yellow; scape above, flagellum entirely, 

 legs above and most of the two basal segments of abdomen beneath, fulvous- 

 yellow ; sometimes the basal joints of antennae above are spotted with black ; 

 wings hyaline, with apical half of costal margin narrowly fuscous and a small 

 fuscous cloud at base of second submarginal cell, costal nervure fulvous; the shape 

 of the marginal find submarginal cells like those of the 9 except that the mar- 

 ginal cell is slightly broader at base and the third submarginal a little larger; 

 venter clothed with a long, loose, pale pubescence, a fringe of long erect bristles 

 on apical middle of segments three and four, scarcely longer than the pubescence 

 ami almost concealed by it: last dorsal segment flat, carinate laterally, the carina- 

 ending at tip in a short obtuse tooth, the last ventral segment slightly protruding 

 beyond the last dorsal and deeply cleft. Length .50 inch.
