 ni/ri-diliila. nf<\^[^ classification will only acquire a deeper interest, when the inheritance of each character has been exam- 

 ined by careful breeding exiieriments. We may presume that one or the other form follows the Jlendelian 

 law, or more cautiously expressed (as each of the above forms has a number of characteristics), it is probable 

 that in species so variable one or the other characteristic is transmitted in accordance with Mendel's law. — 

 popuU'ti. populeti Bien. (39 a). A large Western Asiatic race, which is distributed from South-Eastern Russia to the 

 Altai and the Pamir, and also somewhat differs from populi in the genitalia. The yellowish specimens with a 

 populeio- red tone are ;jo/»//p^" rew, whereas the grey examples b?long to ab. populetorum Stgr. 



'■"'"• A. amurensis. Probably originally the Pacific-Palearctic race of A. pupuli. Found from Russia to the 



Pacific Ocean and Western China, not yet known from" Japan. Smaller than A. populi, with narrower wings, 

 without a light discocellular spot on the forewing and without rust-patch on the hindwing. The haq)e of the 

 J broader than in populi. The egg is described as yellowish with a grey tint. TREiTSfHKE's description of the 

 caterpillar is erroneous, as already suggested by Boisduval. The larva is so similar to that of populi as to be 

 easily confounded with it. The moths, which are on the wing from May until July according to the locality, 

 fly often like popnii above the water, into which they dip like swallows. It is known from certain exotic 

 Sphingids. especially Pachylia, Hemeroplanes, Perigonia, etc., that they behave in a similar way and often 

 drink considerable quantities of water. However, the congue of Amorpha is so strongly reduced that it is 

 hardly like ly that the insects can drink. We mention incidentally that in the case of those Exotics only the 

 uiiiuren.'^U. (^(^ have the habit of drinking water (which holds likewise good with butterflies). — amurensis Stgr. (= tre- 

 mulae Fisch.-Waldh.)(^9 a,). We cannot find any difference between specimens from Russia and Amurland. Bred 

 specimens are more glossy than those which have been at large, amurensis varies in the ground-colour in a 

 rosacea, similar way as^. populi, and we presume that the yellowish and reddish specimens (ab. rosacea iSV-r/r.) are mostly 

 early ones which emerged m the autumn of the same years. Finlan 1, North and Central Russia to Vladivostok. — 

 .■iinira. sinica K. <fc J. Three ,^(^ in coll. Cil\rles Oberthur, one being transferred to the Tring-Museum. Very dark blackish 

 grey : wings broader than in the previous forms, esp:-cially the hindwing. whose distal margin is less produced at 

 thecostal and subco.stal, being much more evenly rounded from the subcostal vein to the anal angle; colouring like- 

 wise more uniform, it being particularly noteworthy that the veins are hardly palerthan ground. West Ciiina.

Similar in shape to Amorphn, but the forewing much more elongate. Second segment of palpi smoothly 

 scaled. Abdomen with long upper- und underscales, and only bearing spines at the edges, the spines moreover 

 t)eing but very feebly chitinised. Tibiae spinose; hind tibia with 2 pairs of spurs; paronychium on each side 

 with one lobe only. Frenulum indicated. — Larva with dispersed granules, the lateral granules larger, with 

 a red ring at their bases ; 7 oblique light side-stripes, which are frequently edged with red in front ; head strongly 

 tapering above, on each side of the frons a blackish stripe, vertex bifid; horii black above, otherwise red, with 

 large dispersed granules ; anal tergite with single pointed granules. Pupa very peculiar; without gloss, most 

 similar to that of Cressonia juglandis (North America); tongue-case not reaching the wing-cases; the granules 

 of the wing-ca.ses pointed; abdomen beneath flattened and densely beset with small granules, the granules 

 of the upperside pointed; on abdominal segments 4, 5 and 6 a subapical belt of pointed tubercles, which 

 are very small on the ventral surface; cremaster broad, flat, truncate with the corners produced into a tooth. 

 Foodplant: Juglans mandschurica. The moth in June and July. Larva and pupa, when irritated, produce 

 rather loud whistling sounds, and the pupa, like that of Kentrochrysalis streckeri, can crawl rather fast with 

 the help of the pointed tubercles. Occurs from Japan and Amurland southward to North India ; Only 1 species. 



P. dissimilis. Ground-colour greyish brown or reddish brown, the markings darker. Forewing with 

 a large irregularly triangular median area which extends from the costal margin, where it is broadest, to near 

 the lower median vein, being dark brown or almost black proximally and posteriorly and more or less completely 

 bounded by a pale tint; disto-marginal area likewise dark, produced basad between the two median veins 

 as far as the dark median area, bounded at the apex by a violet-grey lunule. Hindwing with feeble transverse 



•) salicis seu palusiris HoUe is doubtless best placed with? as a synonym of pallida, as. ba.s been done by Rebkl.
