 broad, 2-9. Legs, 4-1, 2, 3 = 12, 9, 8-5 mm. 



CejjhalotJwrax stone-colom-, tinged Avith olive-green, marked 

 with greenish-black speckled transverse stripes, facial region 

 deeper black; hau's whitish and yellowish, fine, short, ad- 

 pressed, bristle-like on cephalic part ; lengtli fully equals the pa- 

 tellary + tibial joints of a fourth leg; ovate, slightly compressed 

 forwards; pars cephalica convex, roundly truncated, lateral 

 index equals two-thhxls facial ; height of cJypeiLS slightly sur- 

 passes space between anterior centre ej'es ; pars thoracica con- 

 vex, border-hem moderately prominent ; indentation longitu- 

 dinal ; caput and radial striie fairly well defined ; contour of 

 profile visibly cm'ved across fore-end of caput, moderately in- 

 clined to fovea, dips more abruptly to thoracic junction. 



First row of eyes slightly procurved, much the smallest of 

 eight, centrals about one-third larger than laterals, separated 

 from each other by an interval perceptibly exceeding their 

 breadth, and fi'om laterals by rather more than their radius ; 

 side-eyes rather closer to second row than they are to margin 

 of clypeus ; eyes of second row third larger than posterior 

 pair, rather more distant from them than they are from one 

 another, a space equalling an eye's diameter and a quarter ; 

 posterior eyes one-third further from each other than they 

 are from second line. 



Falccs fulvous, lightly clouded ; moderately armed with 

 white hairs ; conical, base gibbous in front, divergent, per- 

 ceptibly inclined forwards, in length scarcely equal to radial -f 

 digital joints of palpus, stouter than the femur of first leg ; 

 double rov,- of 3 close teeth. • 



Maxilla fulvous, somewhat clouded ; base slender, enlarged 

 forwards, rounded slightly, inclined towards labium, latter 

 organ olive-brown, margin pale ; nearly as long as broad,

 lations ; metatarsi have three somewhat obliterated rings ; 

 moderately clothed with outstanding white and black hairs ; 

 spines tolerably numerous on all joints except tarsal. 



Palpi colour and ai-matm-e of legs ; pars humeralis fully 

 equals cubital -f radial joints together in length ; digital joint 

 one-fourth shorter than two latter articles.
