radiating striae in front of anterior ocellus. Face very short, 

 broader than long, broadened above on account of the deeply 

 emarginate eyes, surface medially long-umbonate below antenna, 

 lateral area and clypeus depressed, the former obscurely cross- 

 striate above; mouth opening very large, subcircular, upper 

 margin very strongly curved. Head viewed from side with face 

 , margin strongly curved and verj- prominent at antennal scrobes ; 

 malar space small, length a little more than half width of cheeks ; 

 cheeks broad, more than half width of eye, margin parallel to eye 

 margin ; ocelli strongly prominent ; eye large, its outline long and 

 broadly subelliptical ; of last four joints of maxillary palpi the 

 - second is longest. 



Pronotum nearly hidden by the strongly projecting middle 

 lobe of mesonotum. Mesonotum shining and nearly smooth; 

 notauli very deep, coarsely crenulated anteriorly, becoming 

 broader, shallower, and more obscurely crenulated where they 

 enter the very wide posterior depression, the last with a short 

 median groove, anterior to which the surface is obscurely punc- 

 tate-striate. Scutellum anteriorly with two large subquadrate 

 foveae, separated by a sharp median carina, roughened within, 

 and with curved outer margins; posterior disk of scutellum 

 smooth. 



Metanotum with a thick median carina and on either side a 

 submedian, finer carina, these forming an elongate median area, 

 which is broader posteriorly ; remainder of surface irregularly and 

 obscurely punctate-rugose; below the round spiracle, which is 

 set in a circular depressed spot, is an oblique crenulated furrow 

 passing to apical margin; remainder of metapleura smooth; 

 mesopleura rugose anteriorly and below, disk without oblique 

 furrow. 



Abdomen longer than head and thorax together ; first segment 

 twice as wide apically as basally, length one and one-half times 

 width at apex; second as long as first, gradually broadening 

 apically, the length more than apical width; third and fourth 

 subequal (much shorter than second) ; fifth a little longer; sixth 

 a little shorter, fourth widest ; first four tergites finely longitudi- 

 • nally i-eticulate-rugose ; fifth segment at base obscurely punc- 

 tate-rugose, remainder and sixth segment smooth and shining; 

 first and second tergites with distinct median carina on basal 

 halves only ; second, third, and fourth sutures shallowly depressed 

 and crenulate. Hind tibiae with two long, equal, curved spurs; 

 first hind tarsal joint as long as three following together. 



Stigma large, about three times as long as broad, broadest
