(Plate V, tig. 5.) 



Head ])alli<l fuscous, HecktMl ou the sides with browu and with a 

 uiedioihirsal hlackish brown stripe, wliicli tills the narrow sulcus of tiie 

 fastij^iuni and passes backward much broadened, continuinji: with less 

 depth of color but with e(|ual width upon the i>ronotuni, as far as the 

 posterior limit of the prozona; a similar but weaker brown stripe 

 passes from behind the eye a similar distance, broader and weaker 

 upon thepronotum; antennae i)ale salmon red, paler at base: frontal 

 costa equal, as wi<le as or slij;htly wider than the interval between the 

 eyes, feebly sulcate below the ocellus; fasti<j;ium narrowly and rather 

 dcei)ly sulcate, the sulcation of equal width but varying depth, 

 (iround color of pronoluni yellowish brown, the posterior margin <lis- 

 tinctly but obtusely and not sharply angulate, the disk of the prozona 

 distinctly though but slightly transverse, with no median carina. 

 Trosternal spiiu' short, conical, erect. Tegmina considerably surpass- 

 ing the abdomen, exceptionally slender, wiih very slight subbasal 

 expansion of the costal area, subacuminate ai)ically. brown, but with 

 the larger distal portion i)ellucid, tlecked with brown by the al<^ernately 

 deeper and lighter brown of the veins, the cross veins mostly white or 

 pellucid; wings not much shorter than the tegmina, not very broad, 

 the veins blackish brown anteriorly, brownish blue in the anal area. 

 Hind femora dull luteous, the outer face with three more or less con- 

 tluent, transverse, bla<'kish brown stripes, indicated by transverse fus- 

 cous cloudy bars on the upper faces, the arc of the geniculation heavily 

 nmrked in black: hind tibiae pink, becoming gradually plumbeous 

 distally, the spines pallid on the basal, black on the apical half. 

 Supraanal ])late of male subtriangnlar with i i.'ious sides and a i>ro- 

 duced and rounded apex, the surface ])lane r.r "learly plane, but with 

 two pairs of very slight longitudinal r'lges, one pair bounding the 

 ba.sal median sulcation, which narrows distallv and terminates bevond 

 the middle of the plate, the other lateral, oblique, and less sharp, prox- 

 inially at the lateral margin, distally a little removed from it and ter- 

 minating at a similar distance from the base as the other pair; furcula 

 barely indicated by an attingent pair of scarcely projecting disks; 

 cerci rapidly tapering at base, nearly the entire distal three tifths sub- 

 e<iual, slender, cylindrical, straight, blunt tipi)ed. surpassing slightly 

 the length of the supraanal plate; subapical tubercle of subgeuital
