antennal pectinations are short and fusiform. Forewing smoky grey-brown, somewhat glossy, the dar]<er sub- 

 basal, antemedian and postmedian lines sometimes enclosing slightly darker areas, the central area I'ather narrow; 

 these Unes are edged by pale ones; subbasal aiigalated anteriorly; antemedian strongly curved, subcrenulate; 

 postmedian lunnlate-dentate. Hindwing paler, with postmedian line indicated. Under surface paler, both wings 

 with postmedian line. Areole nearly always single, hihabits Arctic Norway, Lapland, Nova Zembla etc. For 

 a further discussion of this group the reader is referred to vol. 8. Our figure, 9 a, is too broad-winged, too 

 sharply marked and with the median band too broad and I suspect an error in determination. 



Subgenus Lainpropferi/x Steph. (= Anisobole Warr). 

 double. Hindwing with discocellulars biangulate.

C. suffumata Schiff. (9d). A very glossy species, not likely to be confused with any other known to suffumata. 

 me. In many localities very constant, but in some places striking aberrations occur together with the ly|)e- 

 form. — ab. piceata Steph. is almost vmicolorous fuscous. It is a pi-evalent form in some parts of N. England piceala. 

 and Scotland and also occurs in Norway, Switzerland and apparently one or two Asiatic localities. — ab. 

 porrittii Rohs. and Garcln. (= carringloni Rhl.) is a very beautiful aberration with the ground-colour uniformly porrittii. 

 pale yellowish or white, the basal and median bands darkened and all the other markings obsolete except a 

 subapical mark. It occurs in Kent (Dover) and S. W. Yorkshire and apparently bears a Mendelian relationship 

 to the type. — defumata Stichel is a rather smaller (sometimes much smaller), in general weakly marked form defumata. 

 from Northern Scandinavia. Less glossy than m,iima, hindwing not darkened. — Larva of medium thickness, 

 rugose, the incisions well marked; head small, pale brown; body brown of various shades, dorsal surface darker 

 than ventral, the first 5 abdominal segments each with a V-shaped dark mark, pointing forward and containing 

 a small, pale-edged dark mark; setae well developed; spiracles deep black. On Galium in May and June. 

 The moth develops about August but hibernates with in the pupal shell, like Taeniocampa, generally emerging 

 in April or the beginning of May. Sometimes it does not appear till June or even July, but there is no evi- 

 dence of second brood in nature, though in captivity such has occasionally been obtained, in August or later 

 Local in Northern and Central Europe, Russia, Armenia, Altai the Thian-shan and W. China. — minna Btlr. minna. 

 (:= minor Stgr) is generally regarded as a local form of suffumata but may possibly be a separate closely- 

 allied species. Smaller, the median band on an average broader, its distal edge with a broader, more rounded 

 projection, the hindwing generally darker. Japan, Amur, Ussuri, the Kentei Mountains and N. India. 



C. algiricata B. Luc. is described as near suffumata (9d); but as the antennal ciliation is said to be very algiricafa. 

 short I suppose it is not correctly placed here. Expanse 30 ram. Forewing rather elongate, yellow-brownish, . 

 with 3 very distinct black lines, accompanied by dark shading, the first and second (subbasal and antemedian) 

 right-angled outward, the third (postmedian) parallel with the distal margin but with a double outward curve 

 in the middle; between the latter and the margin a brown band running from a point near the apex, anteriorly 

 fuscous; a fuscous patch near the margin. Hindwing above and beneath yellow-greyish, irrorated with brown; 

 forewing beneath greyish, with the second and third lines distinct. Le Tarf, Algeria, in April. The figure 

 suggests relationshig with cupreata. 



C. nitidaria Leech. A handsome species, larger than suffumata and more variegated in colouring, the niiidaria. 

 ground-colour of the forewing shaded with violet-grey, in the distal area whiter between the radials and with 

 an ochreous suffusion about the Z'^ radial and P' median; basal and median areas black-brown, the former 

 ample, with very strongly rounded edge; antemedian line mostly parallel with subbasal, more angled at fold, 

 postmedian gently curved; median area rather narrow, especially posteriorly, in the type interrupted at the 

 fold, 2"** median vein finely white; apex with a dark cloud, divided by fine white oblique line, subterminal 

 line and pale veins. Pu-tsu-fong, June- July; also on Formosa. This species belongs to Warren's genus 

 ParalopMa, cf abdomen with large liair-tufts on the sides of segments 5 — 7. 



C. rotundaria Leech, of which only the ? is known, evidently also belongs to Paralophia. Rather rotundaria. 

 larger than suffumata, the forewing broader, the coloration different, the proximal part of the distal area of 

 the forewing and the entire hindwing (except the fringes) being of a glossy violet-grey instead of yellowish 

 white; the basal and median areas are both very broad, only separated by a double pale line, which is formed 

 as the antemedian of suffumata; subapical dark cloud ill-defined, with no distinct white line anteriorly to it; 

 subterminal line reduced to a row of whitish dots. Under surface more weakly marked than in suffumata, 

 more purple-brownish, both wings with the postmedian indicated and with subterminal row of pale dots. 

 Mou-pin in June. Closely related to the Indian siderifera Moore, but 1 think distinct.
