ZEPHTRUS. 



393 



received specimens from Chang-yang, Central China. Probably this species 

 occurs in Corea, but so far has not been recorded from that locality. 



Dr. Staudinger (Rom. sur Lep. iii. p. 139) states that Dorries found the 

 larva of Z. attilia on oak, and described it as green with yellow dorsal 

 streaks. 



Distribution . Amurland, Japan,'Central China.

*' Allied to T. attilia ; colour the same ; margin of primaries straighter. Above, the submarginal 

 row of white spots in the secondaries larger and more distinct, the third, fourth, and the one 

 near the anal angle centred with black ; below, the ground-colour slightly duskier, becoming 

 still more so towards the margin ; in the primaries is a transverse bar in the middle of the 

 cell, extending from the subcostal to the submedian vein, and almost divided by the median 

 into two spots ; the discal bar ceases abruptly at the third median veinlet ; an extra small 

 spot, just on the division between the middle and apical thirds, between the third median 

 veinlet and the submedian vein : secondaries with a transverse row of three black spots at 

 the base in a descending series from the costal vein, a short bar at the end of the ceU as in 

 primaries ; a transverse irregular bar in the middle third, extending from the costal and 

 narrowing towards the independent vein ; a row of three oblong spots, the first two with 

 the longer axis placed transversely, the third near the inner edge, almost at right angles to 

 the second ; a submarginal row of whitish spots centred with black, more distinct and 

 enclosed in the aforesaid dusky colour ; the orange-red at the base of the tail and at the 

 anal angle more suffused. Expanse of wings 1 inch 3| lines. 



" One specimen taken about the middle of August on the top of the peak, 1 060 feet high, over- 

 looking Hakodate." (Fenton, I. c.) 



This appears to be a rare insect in Japan ; there was but one specimen in 

 the collection of the late Mr. Henry Pryer; this is from Yesso and is 

 probably the example referred to by him in his book. Dr. Staudinger 

 describes the species under the name of T. oberthiiri, and states that it was 

 found on the Ussuri by Dorries, who also obtained it at Askold and Suifun in 

 small numbers.
