joint subequal, fourth joint subglobose, sixth and succeeding segments 

 (present to eighth) cyhndrical, the fifth joint representing a transition 

 between the two types. Pronotura sHghtly longer than broad; ante- 

 rior section produced centrally, the anterolateral angles being obtusely 

 rounded; posterior margin subtruncate; greatest width of the pro- 

 notum across the anterior angles; median sulcus very slight Anal 

 segment transverse, the depth not exceeding one-third the width" 

 posterior margin truncate; median section with a longitudinal sulca- 

 tion. Pygidium triangular, subconoid, the apex truncate. Forceps 

 about equal to the abdomen in length, parallel ; apical regions incurved, 

 meeting, but not lapping; inner margins with a very slight lamellate 

 edge on the basal two-thirds, this edge being crenulate and not dentate 

 feubgenital plate transverse, slightly emarginate centrally. Femora 

 robust, very heavily developed. Tibia shorter than the femora 

 bowed. ' 



General color of the upper surface blackish-brown, slightly pohshed" 

 head, antennae, forceps and limbs pale reddish-brown, deepest in the 

 color on the Umbs. Under surface reddish-brown ; the subgenital plate 

 being of the same pale tint as the forceps. 



9 . Size medium; body strongly depressed. Head about equal to 

 the pronotum in width; antennae imperfect. Pronotum longer than 

 broad; anterior portion produced centrally, the antero-lateral angles 

 obtusely rounded; posterior margin and postero-lateral angles broadly 

 rounded; greatest width of pronotum between postero-lateral angles • 

 median sulcus slight, obsolete posteriorly. Tegmina half as long again 

 as the i^ronotum ; lateral margins parallel, the shoulders rounded ; apical 

 portion, taken as a unit, rounded. Exposed portions of wings about 

 half as long as the tegmina, rounded. Anal segment tra^'ns verse 

 half as long again at anterior margin as deep, contracted, apical portion 

 considerably narrower than basal. Pygidium half as long again a,s 

 basal width, tapering, apex truncate. Forceps considerably less than 

 the abdomen in length, parallel, apical portion moderately hooked- in- 

 ternal margins being a slight lamellate edge, this edge being present on 

 all but the apical fourth, though subobsolete basally ; basal internal sec- 

 tion bearing a very distinct tooth. Subgenital plate deep, about half 

 as broad again as long; apical margin very broadly rounded. 



General color of the upper surface blackish-brown, slightly polished • 

 antenna, limbs, anal segment and forceps reddish-brown, deepest in 

 color on the anal segment and forceps; exposed portions of the wings 

 pale-yellowish, lined along the median edges with brown. Under 

 surface reddish-brown.
