 Leiigtli, 3.50 HUM. 



The same nearly as li(tcl.-,ri l)iit ditlerinu from it as toll,, us: Tlie antenna" are red only 

 up to and including tlie serond funiide joint, the next joint only slif^htly suffused with it'; 

 the tirst funiele joint is much shcu-ter .and sul>(|\i;i. Irate, not half the leni^th of tlie i)edicel 

 (longer than uide and over half the pediiMd's leiigtli in luirLrn ) . The fumation of the fore- 

 wing is nearly of the same iiattern hut iniieh deeper, nearly I, lack, the second stripe more 

 compact and Ijetter delimited so that the clear area under the postmarginal vein stands 

 out as a white sjiot. The alidoiiien is wholly Idack, the teeth at ajiex of scntellum more 

 obtuse, tlie emargination le>s .acute; the Muiti.il niargiii of the jio.sterior femur is less 

 emarginate. The s|iecies lidckcri. moreover, is much nuu-e roliiist. Also, the |u-oxini.-il half 

 of caudal coxa is lilack in this species.

Length, 4. .'ill mm. 



Tli(^ same as I'lrturin lint the scajie is also dark red, iiicliidiiig also the long pedicel .and 

 the tirst two funiele joints (and a ]iart ot the third) ; the alidomeu is reddish only along the 

 median line of the venter; the fore wings bear the same general pattern (as regards fuscatiou) 

 but they are more irregul.-irly fiimated, the two fumated areas less distinctly se]iarated, 

 especially camlad. The jiosterior femora beneath are tootlied less farther proxiinad and the 

 apical emargination (a i-onvexity) is more prononriceil (this crenulatiim of the margin should 

 not be confused with the first tooth which is usii.ally r.-ither large in the family); also from 

 lietween tlu' fine black teeth, arise a s.n-ies of solitary, erect, stiff but short bristles. Post 

 marginal vein huig.

Length, Ti mm. 



Wholly black; fore wings with a coiispiciioiis deep black band across them from the 

 marginal vein, distad of this band obscurely clouded; |«isl marginal vein slightly longer than 

 the marginal. Plate on end of scntellum separated into two distinct, obtuse, plat(dike teet!:. 

 Comblike teeth along ]iosterior fenuir extending along dist.-d three fourths. Pedii-el long 

 siunewhat huiger than the funiele 1 which is rather long, 2 longest, about a tliini longer 

 than I, whiili is twice longer than wide. Two ]datelike teeth on diu-so lateral aspei-t of jiro
