Megarhogas szepligetii sp. nov. 



Pale ochraceous, becoming bright ferruginous on antennae, 

 hind coxae, femora, and tibiae, and darker on fourth to sixth ter- 

 gites ; interocellar area piceous. Wings faintly obscured, smoky, 

 and with an indistinct paler transverse band on apical third; 

 veins brown, upper basal margin of stigma darker. 



Male, length, 8 millimeters. 



Head viewed from above not strongly transverse, eyes very 

 large and strongly bulging; vertex back of ocelli short, rapidly 

 narrowing behind eyes, exposed cheek margin nearly straight; 

 occipital carina straight, not incurved; length of exposed cheek 

 margin scarcely twice the distance from ocelli to eyes, the latter 

 distance more than half the distance from ocelli to occipital 

 margin and two thirds the long diameter of an ocellus ; ocelli of 

 medium size, separated by about half their diameter; surface 

 of vertex behind ocelli smooth and shining; surface in front 

 of anterior ocellus wrinkled only over insertions of antennae. 



Face about as long as wide above where the eyes are deeply 

 emarginate, narrowed below by the strongly outcurved eye mar- 

 gins; surface slightly raised along median line on upper half, 

 slightly, longitudinally depressed on midlateral areae; lateral 

 areae finely, shallowly, obliquely rugose ; clypeus transverse, basal 

 suture subobsolete, apical margin broadly incurved; clypeal pits 

 close to eyes; mouth opening broad, elliptical; outer surface of 

 mandibles minutely roughened. 



Head viewed from side with face strongly prominent below 

 antennae; cheeks narrow, outer margin parallel with eye mar- 

 gins, below about one fourth width of eye; malar space very 

 small, its length about three fourths width of cheek ; both malar 

 space and cheek smooth and shining; eye very large, subellip- 

 tical, broadest on lower half. 



Mesonotum deeply trilobate, smooth or minutely roughened, and 

 shining, notauli deeply impressed, minutely, obscurely crenulate, 

 more strongly so posteriorly, terminating posteriorly at middle 

 of the narrow median furrow on posteromedian area. Scutellum 

 anteriorly bifoveate, the foveae separated by a sharp median 

 carina; posterior disk nearly smooth, long triangular. Postscu- 

 tellum with two small . median foveae separated by a sharp 

 carina, their outer margins oblique. Metanotum reticulate- 

 rugose; a sharp-rimmed, median, lanceolate area crossed by 

 three transverse rugae ; posterolateral areae somewhat prominent 

 and below with radiating rugae; spiracle elliptical, and below 

 it a longitudinal carina passing forward; metapleura depressed
