setae, approximate to PI; puncture Pa remote from other setae and puncture 

 of posterior group, about equidistant from A3 and LI. Lateral seta (LI) 

 approximate to A3; on the level of PI; lateral puncture (La) postero- 

 laterad of the seta, remote. Ocellar setae (Ol, O2, O3) well separated; 

 Ol dorsad of and closely approximate to ocellus III; O2 closely approx- 

 imate to ocellus I, in a line with ocelli I and II; O3 ventrad of C2, remote; 

 puncture (Oa) closely approximate to O3, between O3 and ocellus VI. Sub- 

 ocellar setae (SOI, SO2, SOS) triangularly placed; puncture SOa lying between 

 SOI and SO3, nearest to SOI. Genal seta (Gl) anterior to the puncture 

 Ga, approximate to O3. 



Labrum with median incision broadly triangular, shallow. Median setae 

 (Ml, M2, M3) triangularly placed 1 ; M2 postero-laterad of Ml and closer 

 to Ml than to M3; lateral setae (Lai, La2, La3) nearly in a line; Ml 

 and La2 on a level; Lai slightly below the level of M2; M3 well back from 

 anterior margin, behind the level of La3; puncture not distinguishable. 



Epipharyngial shield narrow, very weakly chitinized, scarcely distinguish- 

 able. Epipharyngial setae triangularly placed near anterior margin of 

 epipharynx; well separated; narrow; moderately long. Epipharyngial rods 

 indicated only by their prominent posterior projections. 



Labium and maxillae normal except for a large, pit-like, oval chitinization 

 (Smp) on posterior part of submentu. 



Maxillulae normal. 



Mandible with a single strong tooth and what appears to be the rudiment 

 of another closely oppressed against its inner ridge ; the lower teeth normally 

 occurring in other forms here replaced by a straight, slanting, distal cutting 

 edge. 



This genus differs from the closely allied Martyringa Busck in 

 having veins 3 and 4 of the hindwing stalked, 5 separate from 4 

 and nearly parallel with 6, and with 4 of forewing well separated 

 from 3. In Martyringa 3 and 4 are united and connate with 5 

 in the hindwing, and 3 and 4 of forewing are closely approximate 

 or connate. Otherwise the two genera agree in adult characters. 

 The immature stages of Mariyringa are unknown, so comparison 

 cannot be carried further. 



Santuzza kuwanii, n. sp. 



Moth. Antennae blackish fuscous with outer margin of basal joint nar- 

 rowly bordered with dull dark greyish yellow. Basal joint of labial palpus 

 blackish fuscous; second joint dull yellowish with patch of blackish fuscous 

 scales on outerside at base; third joint blackish, apical fourth yellow. Head 

 and face dull yellow with a few scattered fuscous scales in front of the eyes. 

 Thorax blackish fuscous faintly suffused with yellowish scales. Forewing 

 blackish fuscous marked with dull yellow; a slight and indefinite suffusion
