beyond the head outline, but deeply entering the head, the 

 distance between them at the ocelli about equaling the length of 

 cheek margin behind eyes; vertex behind ocelli broadly convex, 

 smooth and shining, the distance from ocelli to occipital margin 

 being about twice the shortest distance between eyes; ocelli 

 small, distance between the two posterior a little less than dis- 

 tance from them to eyes; anterior ocellus remote from the two 

 others, separated from them by twice the distance between eyes 

 and posterior ocelli; surface between ocelli and eyes with very, 

 shallow wrinkles. 



Face very narrow at middle, the outline that of a dumb-bell, 

 broadened above by the deeply emarginated eyes, the width at 

 antennae and at clypeal margin being nearly twice that at the 

 middle ; surface with a short, poorly defined median carina below 

 antennse, and throughout finely, obscurely, irregularly rugose; 

 clypeus narrowly semilunate, the clypeal pits separated from the 

 eyes by their own diameter ; mouth opening subcircular. 



Head as viewed from side with margin of face parallel to 

 eye margin ; malar space nearly obsolete ; cheek about one fourth 

 as wide as the greatest eye diameter, its outer margin parallel 

 to eye margin; eye very large, short subelliptical, broadest on 

 lower half; third and fourth joints of maxillary palpi long, 

 subequal. 



Mesonotum deeply trilobed, smooth and shining, the notauli 

 deeply impressed anteriorly, noncrenulate, and running straight 

 backward to lateral angles of scutellum; posteromedian area 

 broadly, evenly, shallow depressed. Scutellum triangular, large, 

 evenly convex, smooth and shining^ anteriorly with a deeply 

 impressed, straight-margined, transverse, crenulate groove. 

 Metanotum smooth and shining; spiracle large, subcircular, 

 raised on a slight prominence, the surface before it slightly de- 

 pressed, beneath it a fime, slightly impressed, longitudinal fur- 

 row. Pleura smooth and shining, the mesopleura without discal 

 impressions; a deep furrow separating pro- and mesopleura 

 above. 



Abdomen sessile, longer than head and thorax together, 

 spindle-shaped, broadest at fourth segment, seven segments being 

 fully exposed; first segment a half longer than wide at apex, 

 the second, the third, and the fourth subequal in length and a 

 little shorter than the first ; the second as long as wide at apex, 

 the remainder wider than long; midlateral arese of first and 

 second segments with broad, shallow, longitudinal impressions, 

 these being parallel with outer margins of segments, and leaving 

 subtriangular, median, raised areas; there are rudiments of such
