INSECUTOR INSCITI^ M^NSTRUUS 49 



posterior group at middle of head; Pi, nearly on a level with 

 Adf2 ; P2 on a level with place of juncture of adfrontal suture 

 with longitudinal ridge; Al, Pi, and P2 in a straight line; 

 puncture (Pa) approximate to and equidistant from A3 and 

 LI ; Pb directly posterior to Pi. Lateral seta (LI) closely 

 approximate to x\3, on a level with Adfa; lateral puncture (La) 

 directly posterior to the seta, remote. Ocellar setae (Ol, 02, 

 03) well separated; Ol equidistant from ventrad to ocelli IT 

 and III ; 03 postero ventral and approximate to ocellus I ; 03 

 remote from and directly ventrad to 03 ; puncture Oa between 

 03 and ocellus VI, approximate to the latter. Subocellar 

 set^e (SOI, S02, S03) triangularly placed; S03 slightly 

 nearer to S02 than to SOl ; puncture SOa almost on a line 

 between SOl and S03. 



Labrum with median incision broadly concaved, rather shal- 

 low ; seta M2 laterad and very slightly back of Ml, equidis- 

 tant from Ml and M3 ; M3 almost directly forward of M2, 

 well back of anterior edge of labrum ; La2 on a line with Ml, 

 near lateral edge ; Lai closely approximate and almost directly 

 laterad to La2 ; La3 on a level with M3 ; distance separating 

 La3 equals that between La3 and M3, M3 and M2, and M2 

 and Ml ; puncture directly lateral to Ml, equidistant from Ml 

 and M2. 



Bpipharyngial shield (ES) a narrow border of chitin along 

 the median incision of the labrum. Bpipharyngial setae (ET) 

 triangularly placed near anterior margin of epipharynx, short, 

 moderately broad, equidistant. Bpipharyngial rods (ER) indi- 

 cated by their posterior projections only; these are moderately 

 long. 



Mandibles rather stout, about as broad as long; three 

 toothed; the lowest tooth small and compressed; two stout 

 setse on the lower side. 



Antenna four jointed ; moderately long and slender joint ii 

 as long as joints i, iii, and iv combined, longer seta extending 

 well beyond extremity of antenna, about as long as the four 

 combined joints, shorter well back of longer seta, papillae nearly 

 as long as joint iii ; joint iii longer than broad and much longer 

 than joint iv.
