 narrowed to apex, first transverse cubital very oblique, second 

 vertical and decolored; recurrent vein joining cubitus a distance 

 before second cubital cell of half length of first cubital cell, in- 

 tervening vein decolored; parallel vein inserted at lower third 

 and strongly curved just before insertion; submedian cell much 

 longer than median, subangularly rounded at apex; the straight

Head viewed from above rather broadly transverse, eyes very 

 large and strongly bulging; vertex caudad of ocelli very short 

 and rapidly narrowed caudad, occipital carina deeply but evenly 

 incurved; length of exposed cheek margin twice the distance 

 from ocelli to eyes or from ocelli to occipital margin, the last two 

 distances being subequal; surface of vertex shallowly rugose; 

 ocelli of great size, set on a slight eminence, separated by less 

 than half their diameter, which is about twice the distance to 

 eyes or to occipital carina; surface in front of anterior ocellus 

 smoothly excavated. 



Face longer than wide, rapidly broadened above to the deep 

 emargination of eyes; surface irregularly, transversely rugose, 

 raised at middle, thence to clypeal border, medially, sharply cari- 

 nate; clypeus with a narrow, rimmed depression on either side, 

 which gradually broadens toward anterior margin ; basal suture
