o. Intennediate ln'tween .^trcckeri aud s/t'rcr.si, but different from both ; of 

 the size o{ streeheri, with which it has generally been confounded. 



In appearance like streckeri, but the external discal lines of the forewing less 

 dentate, the two anteniedian lines distinct, ending at inner margin in a blackish 

 patch which is prolonged basad. 



c?. Tenth tergite (PI. XXVllI. f 23) suddenly narrowed to a short pointed 

 hook; stcrnite (PI. XXVill. f 24) divided into two triangular lobes. Clasper 

 as in siecersi, broadest near base ; harpe longer than the clasper (PL XXXIX. 

 f 15), not unlike that of sierersi, but the ventral process shorter. Besides this 

 process there are five or six more, which vary in form and position in the 

 specimens dissected, the most ventral one being, however, always large. Penis- 

 sheath as in sicversi. 



? . Unknown. 



Larva and chrysalis unknown ; feeds probably on yew.

c?. Antennal segments very feebly dilated laterad, fasciculated ciliae of distal 

 segments shorter than in streckeri. Palpus not hairy. Pilifer with scales and 

 some bristles. Antenna without the large black patch of streckeri, there being 

 only a few brown scales jiresetit in sieversi. R- of hindwing before centre of cell, 

 stalk of SC- and R' longer than in streckeri. 



<S. Tenth abdominal tergite more abruptly narrowed and curved than in 

 streckeri ; sternite very broad, truncate, sides obtusely dentate (PI. XXVIII. f. 25). 

 Clasper widest near base ; inner surface with long thin scales ; harpe very large 

 (PI. XXXIX. f. 17), reaching basally close to dorsal margin and ventro-distally to 

 the apex of the clasper, the ventral finger-like process is short; above it there is 

 a pointed triangular jirocess curving upwards ; the dorso-basal part of the harpe is 

 provided with large teeth. Penis-sheath similar to that of streckeri, the hook 

 longer. 



? . Not seen.

The specimen of " .•i/nY-^v/," of which Leech, Trans. Ent. Soc. Lone/, p. 200 

 (1898), referred to as being darker than sieversi, and which apparently convinced 

 him of the sjiecific identity of streckeri and sieversi, was not streckeri at all, but 

 the new lli/loiries desci'ibed on ji. 144 of this jiaper.
