 throughout blackish fuscous. Only known from the Island of Dursey, olf the west coast of Ireland. Kane 

 believes it is now extinct. — Larva moderately stout, segment-incisions well marked, head small; green with 

 darker green dorsal line, on the thorax very indistinct; subdorsal and lateral lines yellowish white; venter 

 darker green, with yellow lines. On grasses and various low plants, hibernating. Pupa rather strongly 

 sculptured, thorax and wings olive-greenish, abdomen dark red. The moth flies throughout the summer months, 

 as it emerges over a considerable period, while in some localities there seems to be a partial second brood- 



C. grisescens Stgr., which was described as a probable variety of hilineata but afterwards raised to grUeseens. 

 the rank of a Darwinian species, is said to be grey, in the forewing without a trace of brownish or yellowish, 

 in the hindwing occasionally more brownish costally. The markings are about as in hilineata, or with some 

 approach to bistrigata, the median area of the forewing sometimes shows a narrow darker central band. 

 Amasia and Tokat and once in Greece. 



C. bistrigata Tr. (= quadristrigaria Giien.) (lOi), which represents hilineata on Sardinia and Corsica, bistrigata. 

 is likewise considered a Darwinian species. Ground-colour nearly as in testaceolata, but on both wings strongly 

 irrorated with grey; discal dot of forewings enlarged; the transverse lines strong and dark; median area of 

 forewing broad, darker than the areas which adjoin it ; postmedian line more sinuous, with deeper indentations 

 and forming a pronounced bilobed projection in the middle. 



C. consentaria Frr. (= fluidata Led., russariaria H.-Sch.) (13 b). Narrower-winged than the three preceding consentaria. 

 species, more glossy, ground-colour more white, showing in the middle of the median area an indistinct, 

 rather thick white lines bordering the basal and median areas ; these and the intermediate areas less yellowish 

 brown; median area distally as irregular as in bistrigata; subterminal line distinct, rather regular. Hindwing 

 with postmedian line angulated in middle, subterminal line as on forewing. Under surface moderately well 

 marked. Ural, Altai, Tarbagatai Mountains and Amurland. 



C. centrostrigaria Woll. (= mediata Walk., latirupta Walk., luscinata Z.^ interruptata Rbl.) (13 b). This centra- _ 

 and the two following species have often been referred to Horisme but lack the crested abdomen, centrostrigaria ^""''Oana. 

 is variable, the median area sometimes entirely dark-fdled, much more commonly broken into distinct or 

 indistinct dark lines with some darker shading proximally to the cell-spot, or merely with dark proximal and 

 anterior part of distal edge; the distal area of the forewing nearly always shows the costal spot, pair of dark 

 spots between the radials, etc. Distributed in the Atlantic Islands and throughout Eastern America, extending 

 as far south as Buenos Aires. 



C. caespitaria Chr. (= pacuviaria Ob) (13 b) is shorter-winged than polygrammaria, with the lines less caespitaria. 

 oblique, somewhat more sinuous. The distal area is somewhat more irregularly marked, in this rather resembling 

 polygrammata; variable. Amur and Ussuri district.
