prothoracic spiracle broader and more than tvv'ice the size of smaller 

 abdominal spiracles; 8th abdominal spiracle very large, broadly 

 elliptical, near caudal margin of the segment and facing caudal 

 extremity of the body. Body tubercles inconspicuous; various body 

 areas heavily chitinizod. Body setae normal; prothorax with I la 

 <lorso-caudad of la, puncture y between la and Ila, approximate to la, 

 puncture z dorsad of and approximate to lo, Ilh slightly above the 

 level of z, lie widely remote from lib, closely approximate to and 

 belovv' Ic, in a lino with Ic, lb, and la, seta III absent; moso and meta- 

 thorax with Ila anterior or antero-laterad of lib, IV anterior to ///, 

 rather remote, F absent, T7 bisetose; proleg-bearing abdominal seg- 

 ments with // considerably lovrer than /, /// dorso-caudad of the 

 spiracle, /Fand Fon the same level but rather v>ell separated, 7, ///, 

 and IV in a vertical line, group VII triangularly placed; abdominal 

 segment 7 with VII unisetose; abdominal 8 with II on the level of 

 I, II and /// in a vertical line almost over the spiracle, IV and Fin 

 a longitudinal line well forward of and slightly lov.er than the spiracle, 



VII unisetose; abdominal 9 mth I antero-laterad of II, equidistant 

 frora II and ///, IV and V imited; VI present, VII unisetose; setae 



VIII much more widely separated on abdominal segment 9 than on 

 abdominal 8. 



Head partially retracted within prothorax; ovoid-spherical; 

 broadly ovate in outline vievved from above; as vvide as hong; great- 

 est width well back of middle of head; incision of dorsal hind margin 

 very slight; distance between extremities of dorsal hind margin over 

 one-third the vddth of the head. Frons pentagonal, narrow, short, 

 not reaching to middle of head; longituchnal ridge longer than frons 

 adfrontal sutures nearly paralleling the adfrontal ridges, meeting 

 longitudinal ridge just back of the end of frons. Projection of dorsal 

 margin over ventral a trifle more than half the diameter of the head. 

 Ocelli six; F and VI well separated from the rest. Epistoma normal. 



Frontal punctures close together on a level with frontal setae; Adf2 

 at beginning of longitudinal ridge; Adfl closer to xidf^ than to Fl; 

 Adfa between Adfl and Adf2. 



Epicranium with the normal setae and punctures. Anterior 

 setae in very slightly obtuse angle; Al and A2 rather close together; 

 A3 remote from A2; punctures Aa remote from A2, closely approx- 

 imate and dorsad to A3. Posterior setae and punctures well sepa- 

 rated; P2 postero-dorsad of PI; puncture Pb postero-laterad and 

 remote from P2; Pa on a line midway between Pi and LI; the 

 punctures Axa, Pa, and Pb lying almost in a straight line. Lateral 

 seta {LI) well above lateral margin, as far from A3 as A3 is from A2; 

 puncture {La) postero-laterad of LI. Ocellar setae lying almost in 

 a vertical line; 01 approximate to and dorsad of Ocelli II and III; 

 02 antero-ventrad of Ocellus I, in a line with Ocelli VI and I and
