1888.] LEPIDOPTERA OF JAPAN AND COREA. 589 



" lateral black spots on the abdomen." In my series of A. pinastri 

 from Japan, I find that almost every specimen has the body paler 

 where the white markings should be, and dark patches along the 

 sides are distinctly visible. The dark form is most frequent in 

 Japan ; but in Fryer's collection there is one example of A. pinastri 

 which has a pale grey ground-colour clouded with darker, and with 

 strong and sharply defined markings. This is one of three examples 

 labelled no. 16, and noted as occurring newly emerged on stems of 

 yew trees ; the other two are referable to A. davidis, Oberth.

Two fine examples in Fryer's collection. These, as previously 

 adverted to, are two of the three insects (no. 16) found on stems of 

 yew at Yokohama. In one the central area of primaries between 

 tiie transverse lines is pale grey like the rest of the wing, but in 

 the other it is clouded with fuscous, and as a consequence the wing 

 appears to have a broad fuscous transverse fascia. Neither of these 

 specimens agree exactly with Oberthiir's figure of ^. davidis, but there 

 can be no doubt they are forms of that insect, as also is Sphinx 

 strecheri, Stand., from Vladivostok. Amurland specimens of A. 

 davidis in my collection are rather darker than my Japanese examples, 

 and seem to fit in between these last and specimens of S. strecheri 

 from the Amur.

One example, taken at Hakodate by my native collector in June, 

 does not differ sufficiently from European examples to deserve 

 specific rank.
