large and very strongly bulging; vertex back of ocelli short and 

 rapidly narrowing behind ^es, but with cheek margin not out- 

 curved; occipital carina forming a very broadly obtuse angle 

 at middle; length of exposed cheek somewhat more than twice 

 distance from ocelli to eyes, the latter distance about half the 

 distance from ocelli to occipital margin and half long diameter 

 of an ocellus ; ocelli very large, the two posterior separated by 

 less than half their diameter, the anterior more widely sepa- 

 rated; surface of vertex behind ocelli smooth and shining; sur- 

 face in front of anterior ocelli shallowly, sparsely, radiately 

 wrinkled. 



Face as long as wide above, where the eyes are deeply emar- 

 ginate, narrowed below by the strongly outcurved eye margins ; 

 surface raised along median line, depressed on midlateral area 

 and obscurely and irregularly transversely rugose-punctate, 

 except medially; clypeus transverse, basal suture subobsolete, 

 apical margin little incurved ; clypeal pits close to eyes ; mouth 

 opening broadly elliptical; second joint of labial palpi and third 

 joint of maxillary palpi apically somewhat swollen; outer sur- 

 face of mandibles minutely roughened. 



Head viewed from side with face strongly prominent below 

 antennse; cheek narrow, outer margin parallel with eye margin, 

 below about one fourth breadth of eye ; malar space very small, 

 its length about three fourths width of cheek; both malar space 

 and cheek smooth and shining, but with a very small cross- 

 striate area next to lower eye margin ; eye very large, subellip- 

 tical, broadest on lower half. 



Mesonotum deeply trilobate, smooth or minutely roughened, 

 and shining; the notauli deeply impressed, minutely crenulate, 

 and terminating posteriorly at the middle of the narrow median 

 furrow on posteromedian area, scutellum anteriorly bifoveate, 

 f ovese separated by a sharp median carina ; posterior disk nearly 

 smooth, long-acute triangular. Postscutellum with four small 

 fovese separated by sharp carinse, median carina the strongest. 

 Metanotum coarsely reticulate-rugose; a sharp-rimmed, median, 

 lanceolate area crossed by three transverse rugae; posterior 

 lateral arese somewhat prominent, below with radiating rugs; 

 spiracle elliptical, a longitudinal carina just below it, extending 

 one half length of metanotal margin; metapleura broadly de- 

 pressed posteriorly, and with a few irregular rugse about 

 border of depressed area, very shallowly rugose anteriorly, a 

 deep furrow near anterior margin is crenulate above; meso- 

 pleura smooth and shining, posterior border crenulate, disk
