needs to be considered even an aberration and it is doubtful whether Stauder would ever have described it 
if he had not unaccountably referred his specimen (a $ from Castellammare di Stabia) to Etipithecia, where 
(naturally) he could not find a determination for it. Apart from its small size I can see nothing exceptional 
about it. 
C. chloerata Mab. (Vol. 4, pi. 13 k) occurs also in Sweden (Nordstrom). — ab. nigrofasciata Dietze. chloerata. 
Median area darkened; corresponding to a similar form of rectangulata . Mecklenburg, one example, taken rngrofascia-^ 
among the type form. 
C. hypopyrrha West (14 1) is near rectangulata , with a similar scheme of underside, but is gayer (red- hypopyrrha. 
mixed), with red suffusion round the cell-spot, the subterminal daik band strongly interrupted between the 
dark costal spot and the pair at the radials, which are heavily daikened. Honshu, Japan. 
C. obscura West (14 1), also from Honshu, is very close to consueta (Vol. 4, p. 298), very likely a giant obscura. 
form of the same, but the palpus may be slightly longer in proportion (it looks slightly over twice the diameter 
of the eye in obsura, about — or scarcely — twice in consueta) and the ochreous tint of the abdomen above 
seems more extended. It was founded on 1 $ and one feels that more material is needed. 
C. subcinctata Prout (18 f). I have not yet seen further specimens, except, apparently, a defective $ subcinctaia.

thrax Dietze. Both wings darkened throughout, even the subterminal obliterated. Probably not separable from aniJirax - 
nigrosericeata Haw., in which Bietze thinks to detect traces of the green colouring of the type. — ab. brun- brunneata. 
neata Dannehl, described from the S. Tyrol, has the ground-colour light brown instead of green and at first 
sight suggests old and discoloured specimens, but has been bred and taken quite fresh. — ab. ochrea Derenne ochrea. 
is another (?) colour-modification, described as ochre-yellow. A specimen from Surrey, figured by Culot 
(fig. 908), is referred here and Derenne took one at Ixelles, Brussels. — ab. bistrigata Dietze. Ante- and post- bistrigata. 
median lines of forewing considerably strengthened. Sc-hlern, S. Tyrol; perhaps pathological. — ab. joannisata joannisata. 
Culot combines the bright green of the type with a black-brown median band. A beautiful specimen in the 
Joannis collection; locality not indicated. 
C. chingana Wehrli. Ciliation very short. Face projecting. Yellowish grey-brown, dulled with numerous chingana. 
fine dark atoms. Forewing with the basal, 2 subbasal, the double antemedian and the median line (which 
touches the black cell-dot) rectangularly bent near the costa, thence straight and parallel, in this distingui¬ 
shable at once from rectangulata; postmedian much as in that species, but more strongly waved and dentate, 
the band outside it scarcely paler; subterminal regularly dentate, below the costa and above the middle with 
macular dark shading on each side; termen with shallow" black lunules. Hindwing with the lines more distinct 
than in rectangulata, the postmedian more weakly angled. Underside lighter; forewing with sharp black cell- 
dot, costal part of median line and similar postmedian to that of upperside; hindwing with lines and cell-dot 
sharper than above. Inn Shan. Chingan Mountains, Mongolia, 2000 m, 1 C- 
C. debiliata Him. (Vol. 4, pi. 13 k). This name is only precariously held by the present species, as debiliata. 
Hubner figured a prior debiliata (pi. 90, fig. 462) which w r as by no means certainly the same as our bilberry 
insect (pi. 91, fig. 466). The plates may, how’ever, have been issued simultaneously and it is to be hoped the 
name can stand. I had thought to add as a synonym clerci Krulik., which is unknown to me and was sunk 
by its author, though as an “aberrative” specimen. — ab. loc. grisescens Dietze (= clerci Krulik.) seems, how r - grisescens. 
ever, to be the more accurate synonymy, as Kolossow says that clerci is “entirely light-grey, without a trace 
of greenish". According to Dietze this is in many localities the sole or the prevailing colour-form of debiliata.

(See Vol 4. p. 299; Vol 16, p. 95). 
It is very doubtful whether this genus, in the restricted sense, belongs at all to the Palaearctic Region. 
In addition to the characters noted, the $ almost always has the midtibia thickened, with a groove on the 
innerside and both sexes the outer spur thereof less than U the inner. “Section B ’, Pseudocollix, can, I think, 
be merged in Horisme, with the exception of sparsata, which is regarded as sui generis, see below. 
C. griseipalpis Wileman ? (= hypospilata Wileman, nee Guen.). The Japanese $ (Chinan, Satsuma. griseipalpis. 
August 1895), mentioned in Vol. 4, p. 300 under hypospilata, is not very fresh, but seems to agree closely with
