ly long black hair. The grej' pubescence on the tergites short, recumbent 

 and sparser than on the mesoscutum, longer, somewhat thicker and at 

 least much more prominent, liowever, on the black apical segments. 



Legs rather short and stout ; the front tibiae a little swollen and 

 faintly constricted beyond the middle; the hind femora somewhat swol- 

 len; the hind tarsi long, the apical joint thickened towards the apex, ex- 

 cluding the claws about five to six times as long as the fourth joint or 

 nearly as long as the second to fourth joints combined which are equal 

 to first ; all the claws including those of the front tarsi simple, slightly 

 thickened at base, moderately incurved at apex and rather small, the 

 pulvilli shorter than the claws. 



Areolet of front wings rather large, broadly sessile or almost pentag- 

 onal ; the discocubital vein slightly arcuate and not broken ; apical 

 abscissa of the radius very nearly straight ; nervulus interstitial, or only 

 slightly antefurcal ; nervellus of hind wings broken somewhat more than 

 half-way above the middle. 



Length: 8 mm., the ovipositor 1.25 mm. 



$ Similar in color to the female throughout ; the first five segments 

 of the abdomen ferruginous, the sixth segment black with the apical and 

 basal margins narrowly ferruginous or varying to almost entirely pale 

 except a narrow subapical blackish band ; antennae slightly darker. Legs 

 concolorous with base of abdomen, or the front and middle pair 

 varj'ing to yellow, with the upper side of the femora and the ape.x of the 

 middle tibiae remaining a little darker or more reddish ; the hind tro- 

 chanters and basal part of the pale band on hind tibiae varying to yel- 

 lowish ; claws of front tarsi towards apex and their pulvillus, the apical 

 third of the last joint of the middle and hind tarsi, apex of the first 

 and second joints of the hind tarsi, apex of hind femora and base of 

 hind tibiae narrowly, with tlie apex of the latter more broadly, black 

 or blackish. 



Eyes rather more deepl\- emarginate than in female ; the antennae con- 

 siderably stouter, the flagellum composed of 23 to 24 joints, attenuated 

 at base and somewhat less so towards apex ; head otherwise, and the 

 thorax as in female. Abdomen proportionately slightly longer and nar- 

 rower than in the female, the segments less transverse since the eighth 

 is usually nearly entirely retracted within the seventh, whereas it is 

 always prominent in the female; basal tergite about a third longer than 

 its apical width, strongly constricted at base, the basal third obliquely 

 declivous witli two dorsal carinae which strongh^ converge but do not 

 meet posteriorly, the enclosed area slightly excavated and more deeply 

 so at the base ; the apical part nearl}^ quadrate, sliglitly and broadly 

 furrowed medialh% declivous on the sides and with lateral carinae behind 

 the spiracles which are situated a little before the middle of the seg- 

 ment ; second tergite not greatly wider than long, the third to fifth the 

 most tran,sverse, the sixth a little longer than the preceding segment, the 

 •seventh triangular with tlie apex rounded, as long as wide, and a little 

 longer than the sixth ; eiglitli tergite wlion drawn or dissected out is
