half than on lower half; maxillary palpi longer than anterior 

 femora, with third and fourth joints a little flattened, but very 

 greatly enlarged, diameter of first gradually increasing proximad 

 until it is more than twice the diameter of anterior femora, fourth 

 joint nearly as wide basally as third apically and gradually nar- 

 rowed to apex ; length of first joint nearly twice length of a man- 

 dible, fourth about three fourths as long, fifth joint short and 

 broad, sixth stylate. Labial palpi stout, longer than long diameter 

 of eye, second joint somewhat swollen and subequal to fourth in 

 length, third joint shorter. 



Mesonotum trilobate, shining, subobsoletely punctulate. No- 

 tauli deeply impressed and strongly crenulate as far as the middle 

 of the narrow postero-median area, which has a long, strongly 

 pitted median groove, Scutellum anteriorly with two very large 

 fovefe, each of which has a low, rudimentary median carina. 

 Disk of scutellum punctulate, a little longer than broad. Meta- 

 notum coarsely and strongly reticulate-rugose, a rudiment of 

 median carina at base and a blunt projection on either side in the 

 position of the spines in Gyroneuron, to the summits of which 

 pass a number of radiating rugae; spiracle elliptical, not at all 

 raised, Mesopleura smooth, posterior submargin crenulate, an- 

 terior submargin indistinctly, sparsely, longitudinally striate, on 

 posterior half of disk with a short and broad longitudinal furrow, 

 which is crenulate only near the upper border. 



Abdomen subsessile and subelliptical ; lateral margins of first 

 three segments, except base of first, in a straight line ; first tergite 

 broad, the length one and one-half times the apical width, gradu- 

 ally narrowing proximad on apical two thirds, but narrowed 

 suddenly on basal third ; second tergite as long as first, gradually 

 broadened apically ; third and following, including the very short 

 seventh and eighth, progressively shorter and, after the third, 

 narrower ; first and second tergites with a distinct median carina ; 

 all tergites, except seventh and eighth, coarsely, strongly, longi- 

 tudinally rugose with frequent anastomosings. Hind tibiae with 

 two long, curved, subequal spurs, which are longer than fourth 

 tarsal joint. 



Stigma long and narrow, more than four times as long as wide, 

 radius inserted at basal third, apical two thirds rapidly narrowed 

 to an acute apex; first abscissa of radius more than one third, 

 but less than one half, length of second ; second cubital cell two 

 and one-half times as long as wide; first transverse cubitus 

 oblique and straight, the second vertical and decolored ; recurrent 

 vein inserted a short distance before apex of first cubital cell.
