CALLOPHRYS RUBI.

come Strymon pruni and S. w-album. S. pruni comes nearer C. rubi, 

 perhaps, than S. w-album does, at any rate, it is near S. w-album. 

 Then at a little distance come the ilicis, acaciae, and spini group. Then, 

 after a wider interval, Bithys [querciis), and further on — still further 

 from querciis than querciis from ilicis — come Ruralis (betulae) and 

 Laeosopis (roboris), these two being much nearer to each other than 

 their wing patterns suggest." Chapman adds that "It does not follow 

 that a correct arrangement will be in line like this, with either end 

 first, but it does give a probably fair measure of the distance apart 

 (from each other) of the several species." 



The genus Callophnjs appears never yet to have been thoroughly 

 described. We are, therefore, greatly indebted to Mr. G. Bethune- 

 Baker for the following diagnosis : — 



Imago. — Head largish, thickly clothed with broadish scales, interspersed with 

 many long fine hairs. Face nearly flat, projected slightly in front of the eyes, 

 moderately broad, vertex with, a tuft of curved hairs projecting over the sockets of 

 the antenna?. Eyes moderately large and prominent, hairy. Antennae shortish, 

 inserted at the apex on the outer margin, the full width of the face between them, 

 ending in a gradually tapered club Palpi slender, porrect, not as long as the head, 

 second segment thickly scaled with long hairs below, end segment half as long as 

 the second, smoothly scaled. Patagia long and slender, rather narrow, tapering 

 rapidly for the apical half; hairs long, silky, recumbent. Primaries one-third longer 

 than broad, costa deeply and sharply arched at the base, then straight to the apex, 

 which is very shortly and very slightly depressed ; termen with a slight even curve 

 from apex to tornus, inner margin slightly excised about the centre. Neuration : 

 vein 2 from well in front of the lower angle, 3 from just in front of the angle, 

 4 from the angle, 5 from the middle of the discocellulars, 6 and 7 from the upper 

 angle ; in the <$ vein 7 extends into the apex, in the ? it extends to the costa just 

 before the apex, 8 and 9 absent, 10 from the cell near the angle, 11 from about the 

 middle of the cell, 12 a little longer than the cell. Oell broad, not half the length 

 of the wing. Secondaries broad, costa slightly flattened, termen evenly rounded. 

 Neuration, two internal veins, 3 and 4 from the lower angle of the cell, 5 from just 

 above the middle of the discocellulars, 7 from behind the upper angle, i.e., from the 

 cell, 8 short, very highly and suddenly arched near the base towards the cosia, with 

 a slight recurve near its end. Legs — S fore tarsi longer than the tibiae, terminating 

 in a single hook ; ? about the same length as the fore tibiae, terminating as the 

 other legs. Mid-tarsi in ^ nearly twice as long as the tibiae, armed for the whole 

 length with short fine spines ; ? tarsi not so long. Tibiae in both sexes with a pair of 

 short spurs. Hindlegs in both sexes with" tarsi longer than tibiae, armed with fine 

 spines for the whole length ; tibiae with a pair of minute terminal spurs. All the 

 femora heavily haired ; tibiae and tarsi finely and densely scaled. Genitalia : Allied 

 on the whole to those of Strymon w-album. Clasps of a long wedge shape, tapering 

 gradually to a blunt point. Girdle very broad, rather short, strongly curved 

 forwards, united with an ample tegumen, which has strong long falces, very 

 sharply curved about a third from the coupling joint. Penis-sheath very long and 

 narrow, of almost even width for its whole length, with the orifice very slightly 

 expanded.
