^^o. 2305. ON SOME FOREST LEPIDOPTERA—HEINRWH. 77 



metathoracic shields. Spiracles moderate, elongate oval; that on 

 8th abdominal segment slightly smaller than prothoracic spiracle, 

 on the same level, but twice the size of those on abdominal segments 

 1 to 7. Body setae normal. Tubercles large but weakly chitinized. 

 Prothorax with Ila above the level of la; distance from la to Ila 

 equal to that between Ila and lib; pimcture x dorso-caudad of la; 

 puncture z approximate to 11; prespiracular shield triangular, 

 situated close to the anterior margin of the segment and with its 

 lower edge on a level with the top of the spiracle. Setae ///, IV 

 and V rather closely approximate and equidistant on prothorax, 

 well separated and equidistant on meso and meta-thorax and abdomi- 

 nal segments; /// above and IV directly caudad of the spiracle on 

 abdominal segments 1 to 7; / higher than // on first segments of 

 abdomen, latero-cephalad of II on abdominal 9; VI unisetose on 

 meso and meta-thorax; VII unisetose on abdominal 8 and 9. 



Head well retracted within prothorax; ovoid; ovate in outline 

 viewed from above; as long or longer than broad; greatest width 

 well forward of middle of head, just back of the level of Ocellus /; in- 

 cision of dorsal hind margin deep and narrow at least one-half the width 

 of head ; distance between extremities of dorsal hind margin about one- 

 third the width of the head. Frons very short, somewhat heart shaped, 

 as broad as long; adfrontal ridges nowhere parallel, sinuate and 

 curving to a longitudinal ridge (LR) as long as the frons; adfrontal 

 sutures sinuate, extending to incision of dorsal hind margin. Pro- 

 jection of dorsal margin over ventral more than half the width of 

 the head. 



Ocelli six; in the normal Tineid arrangement, with I and II close 

 together, /// and IV close together and well separated from I and II, 

 V approximate to IV, VI well separated from other ocelli; / and VI 

 small and weak. 



Epistoma normal. 



Frontal punctures (Fa) close together, only slightly foreward of 

 frontal setae (Fl); distance from Fl to Adfl about equal to dis- 

 tance from Adfl to Adf2; puncture Adfa forv/ard, closely approxi- 

 mate to AdfS; Adf2 situated a little forward of beginning of lon- 

 gitudinal ridge. 



Epicranium v/ith normal number of setae and punctures. An- 

 terior setae {Al, A2, A3) forming a right angle; puncture Aa 

 lying between Al and A2; A2 and A3 on a level with Adfl; 

 lateral seta {LI) approximate to anterior group, on the level of 

 PI; distances between A2 and A3 and between A3 and LI 

 equal. Posterior setae {Fl and P2) close togther, forward of 

 middle of head; P2 postero-laterad of PI; posterior punctures 

 well separated; Pa laterad of and remote from P2; Ph postero- 

 <lorsad of P2, closely approximate to first ultraposterior seta
