delicately reticulate, the abdomen more distinctly -eticulate with the 

 lines on the first termite arranged more or less concentrically, more dis- 

 tinctly so towards the middle of the segment, the middle tergites 

 smooth and polished, the last tergite more coarsely reticulate with 

 longitudinal lines and appearing somewhat rugulose. 



Eyes with a very tine, sparse pile; cheeks, lower part of face, 

 anterior orbits of eyes, and the frons with moderately abundant whit- 

 ish pubescence; oral margin with a fringe of much longer white hairs; 

 mesoscutum, axillae and scutellum with a moderately dense, appressed 

 white pubescence of short flattened hairs, the scutellum with a pair of 

 rather long, black bristles at apex and a pair of shorter bristles placed 

 just in front of the apical pair and more towards the sides; metapleura, 

 first tergite and sides of abdomen with a few scattered, very fine, whit- 

 ish hairs. 



Length: ( i.oo to) 1.87; width of vertex: 0.219; width of mesoscutum: 

 0.52; length of fore-wing: T.37; width of fore-wing: 0.523 mm. 



Head black, the mandibles reddish brown ; scape shining black with 

 a broad, transparent white band just before the apex, base of pedicel 

 black, the apical two-thirds white, funicle blackish gradually becoming- 

 paler distad so that more or less of the sixth and sometimes part of 

 the fifth joint becomes yellowish white like the club. Mesonotum dull 

 ochraceous orange (R.), the anterior margin of the scutum blackish, 

 or more rarely and apparently only in small specimens the whole scutum 

 except laterally and the central part of the scutellum may be sufl^used 

 with black ; posterior margin of the propleura, anterior part of the 

 mesopleura and the mesosternum nearly concolorous with mesoscutum ; 

 rest of the propleura and pronotum black ; most of the mesopleura, 

 the metanotum, propodeum and abdomen blackish, the metapleura and 

 sometimes the base of the venter brown ; prepectal plates and tegulae 

 whitish. Legs maize yellow (R.), the coxae more whitish the tarsi 

 deeper yellow with apex of the last joint blackish. Wings hyaline, the 

 vejns yellowish brown. 



Male : Head much thinner fronto-occipitally than in the female, the 

 curvature nearly uniform from oral to occipital margin, as seen from in 

 front somewhat broader in proportion to the length, being widest above 

 the middle of the eyes ; the latter more protuberant and considerably 

 smaller; frontovertex plainly wider than long, the ocelli in a slightly 

 obtuse-angled triangle, the posterior pair about as far removed from 

 either the eye or occipital margin as one half their distance apart ; face 

 and cheeks considerably longer than in the female, the scrobes in the 

 form of rather short parallel furrows extending upward to the middle 

 of the eyes and separated by the facial prominence, which is not 

 arched and smaller than in the female so that it is hardly visible in 

 side view of head. Antennae inserted close together just below the 

 lin'j connecting the lower corners of the eyes and far removed from 

 the oral margin ; scape somewhat shorter than in the female, compressed 

 but much less expanded beneath, being narrowly oval or about one
