31. At'idalia iiuligoiiata Wileman. — 1 $, 8uisharyo, October 1911. 

 1 am not at all sure whether this is anything more than a larger, darker 

 (greyer-tinged) form of the preceding. but as the hindwing appears 

 slightiy less strongly angied at R'^ and slightiy more cremilate throughout 

 I hesitate to sink it, 



*32. Acidalia syltillaria Swinh. — 3 V, Aiikang, November 1909, 

 Suisharyo. December 1911. Kosempo. 7 May 1912. Oniy the first is 

 in perfect condition: this and a $ from Koamana in coli. Wüenian have 

 rather larger celi-dots and more shar]ily marked underside than Swinhoe's 

 types from Ichang. The othei exampies are larger, that from Suisliaryo 

 greyer, weakiy merkcd, that from Kosempo very worn. the diseal dots 

 large. Identification somewhat uncertain.

 ()(;tober 1911) fuliy agree with this widely tUstributed Indian species, 

 nnless p{Mlia])s the teeth in the postmedian iine be a üttle stronger 

 than nsuai. Thus my personata (Seitz Macrolep. IV, p. 60) cannot 

 be, as I suggestcrd, the eastern representative of the sanie. The gronp 

 is. however, an exceedingly difficnit one, depending largelj^ on siight 

 distinctions in the 3 hindtarsus, and I a.m now inchned to tliiidv 

 that Fletcher may be right insinking artuaria to niinornta Bsd. A worn 

 9 from Anping, May 1912, probably beiongs also to actuaria, possibly 

 to jx^r Sonata.
