of equal length, and the fifth joining the fourth in an oblique direction ; 
lastly, the lower lip (fig. 8 d) is oval, and has three fleshy lobes, and 
two hairy four-jointed palpi. The eyes are black, oval and prominent; 
the ocelli are disposed in a triangle. The thorax is yellow on the 
under surface, red and black on the upper; the prothorax, the 
diamond-shaped central lobe of the mesothorax, the scutellum and a 
spot behind it on the metathorax are red. 
The abdomen is in the female somewhat thick, cylindrical in the 
male, of an orange-yellow colour, the first segment being generally 
more or less black. The valves of the sheath in the female are also 
black at the tip. The saw and ovipositor are of a clear ochre-brown, 
rather elongated, somewhat curved, and transversely plicated (fig. 9). 
The legs are not very long; coxz yellow; the anterior pair generally 
have some black spots at the base ; femora moderately expanded, pale 
orange; tibiz yellow, black at the ends, with a silky pubescence ; tarsi 
rather long, white, with a black termination to each joint; the first four 
have rather large pulvilli on the under surface, the two last have sharp 
black claws. 
The wings are pretty large, yellow at the base, translucent and 
iridescent at the tip. The whole anterior margin as far as the stigma 
is black; the stigma itself is also black, but gray at the end. 
I have observed but few varieties ; some examples have the antennz 
entirely black. Two individuals, which, if I remember rightly, came 
from green larvee, had Jarge black spots on the middle of the breast. 
It is remarkable that a species of Athalia occurs in Japan, which 
exactly agrees with the insect found in Europe, excepting only that 
the wings are smoke-coloured ; there are some examples of this species 
or local variety in the Museum of Natural History at Leyden, collected 
during the voyage of Mr. Von Siebold. Why Fabricius should have 
given this species the name spinarum, and Panzer should have called 
it Centifolie, I cannot imagine; perhaps the first-named author may 
have found it on the blossom of the hawthorn and the latter have ob- 
served it on a garden rose; at all events it appears from what has 
been said above, that it has no connection with hawthorn or Rosacee. 
A very nearly allied species is named Rose, L., probably through 
confusion with Hylotoma Rose, F., the larve of which live on rose 
plants. It may be that Panzer, merely to indicate the relationship of 
the two species, has taken the name of Centifoliz for that species 
which he thought was unnamed at the time he described it.
