seta A3; puncture Oa between OJ and ocellus VI; 03 ventrad of 

 02, remote, well below the level of Ocelli V and VI. Subocellar 

 setae triangulaii}^ grouped, nearly equidistant; puncture SOa equi- 

 distant from SO.J and SOS. Genal seta (Gl) antero-ventrad of 

 the puncture (Ga). 



Labrum rather short with median incision a shallow triangular 

 notch; seta 2l2 postero-laterad and closely approximate to Ml; 

 MS on the level of La3, close to anterior margin of labrum and remote 

 from Ml and M2; Lai, La2, and La3 along anterior lateral margin; 

 Lai and La2 close together, on the level of M2 and Ml, respec- 

 tively; puncture posterior to M-2. Epipharyngeal shield conspicuous, 

 completely surrounding the notch. Epipharyngeal setae narrow, 

 pointed, rather long; situated well back of anterior lateral margin 

 of labrum. Epipharjmgeal rods well developed, continuous under 

 setae Lai, La£ and LaS and extending as far as MS; posterior projec- 

 tions long, slender. 



Maxillalae (fig. 49) with large fleshy lobes densely clothed v/ith

 each other; a belt of heavy thorn-like spines on abdominal segments

 end rounded, sm-ooth; epicranial suture not distinctly indicated; 

 vertex as long as pro thorax; pro thorax m.uch shorter than meso- 

 thorax; pilifers very large ; maxillary and labial palpi not indicated; 

 pro and mesothoracic legs not extending cephalad between sculp- 

 tured eyepiece and antennae; femora of pro thoracic legs clearly 

 indicated; meso and metathoracic legs extending beyond wings; 

 antennae extending only two-thircjs the wing length; maxillae short, 

 not over half the wing length; no dorsal suture between 9th and 10th 

 abdominal segments; anal and genital openings slit-like in both
