Male genitalia (pi. 4, figs. 19-20) with 8th abdominal segment 

 developed into a hoodlike covering for the clasping organs; uncus 

 developed, short and broadly spatulate; arms of gnathos fusing into 

 a single strong hook; sicae symmetrical projecting backward from 

 vinculum as far as the tip of the aedoeagus; harpes symmetrical, 

 simple, narrow, elongate, needlelike, slightly curved; aedoeagus 

 fairly long, tubular, ta])ering, somewhat curved, moderately stout. 



Larva (pi. 7, fig. 3.5; pi. 8, figs. 4.3, 44, 45, 46). Subcyhndrical. Legs 

 and prolegs normal. Crochets unevenly biordinal and in a complete 

 circle, weak on the outer side. No anal fork. Prothoracic shield 

 moderately broad, divided. No mesothoracic or metathoracic 

 shields. Spiracles minute, round; prothoracic and 8th abdominal 

 spiracle somewhat larger than those on abdominal segments 1 to 7. 

 Body setae normal; tubercles small, inconpicuous ; setae III of 8th 

 abdominal segment directly in front of the spiracle; Ilh of pro thorax 

 closer to Ila than Ila is to la; puncture z approximate to 76, below 

 the level of lib. 



Head capsule flattened, subspherical, square in outline viewed from 

 above, as wide as long; greatest width at middle of head; incision of 

 dorsal hind margin less than one-third the width of the head ; distance 

 between dorsal extremities of huid margin nearly one-half the width 

 of the head. Front longer than wide, reaching to incision of dorsal 

 hind margin, pentagonal in outline; adfrontal ridges (ADFR) 

 straight and parallel from lower limits of epistoma to points of junc- 

 ture of tentorial arms thence converging in straight lines to incision 

 of hind margin; points of juncture of tentorial arms at middle of 

 adfrontal ridges; adfrontal areas of frons appreciable, broadest toward 

 the dorsal hind margm. 



Ocelli six; 7, 77, V, and VI arranged in a parallelogram; 777 and 

 IV nearly in a straight line with 77 and V; I and 777 larger than the 

 rest. 



Epistoma normal. 



Frontal punctures (Fa) close together well forward of frontal setae 

 (Fl); adfrontal setae {Adfl and Adf2) approximate, distance sepa- 

 rating Adfl and Adf2 less than distance from Adfl to Fl ; adfron- 

 tal puncture (Adfa) behind Adf£. 



Epicranium with the normal number of primary setae and punc- 

 tures. Anterior setae (Al, A2, A3) in almost a straight line with lat- 

 eral seta {LI); LI approximate to A3 anterior of the level of PI; 

 anterior puncture {Aa) directly posterior of A2; posterior setae {Pi 

 and P2) situated near middle of head, on a level respectively with 

 Adfl and Adf2; P2 posterior-laterad of and closely approximate to 

 PI; puncture Pa between LI and PI nearer the former than the 

 latter; Ph midway between P2 and adfrontal suture; Pa, P2, PI, 

 and Adfa lying nearly in a straight line; lateral puncture {La) poste-
