GYMNOSCELIS; CHLOROCLYSTIS. By L. B. Prout. 



74. Genus : Gyiuno^celis Mab. . 



Characters of Eupithecia, but with the median spurs of the hindtibia entirely wanting or quite rudimentary. 

 Life-history similar to that of Eiipithecia. 



This genus is chiefly Indo-Australian, though represented also in the Palearctic Region and N. America. 



pumilata. Q. pumilata Hbn. (=: bistrigata Haic, recictaria Bsd,, improbata Zell., pauxillaria H.-Schdff.) (12 m). Very 



variable but easily known by the form of the markings and generally by the reddish bands, sharply marked 



parvularia. hindwing with wedge-shaped markings line etc. The name-typical form is brightly coloured. — parvularia H.- 



tempesHvata. Schdff. (gen. aest. ?) is a small form perhaps resulting from quick growth and dry innutricious food. — tempestivata 



Zell. (= globulariata Mill., incertata Mill) is a greyer, less red-marked form. S. France, Andalusia, Sicily, 



insulanaia. Algeria, etc. — insulariata Staint., from Madeira and the Canaries, is generally darker, postmedian line of both 



postgenitata. wings more dentate, inbent between ra'dials. Variable, often large. — postgenitata Dietze has the basal area of both 



wings darkened, the median area remaining whitish. Osch (Turkestan) and Syr Daria. — Larva polyphagous 



and extremely variable, in a succession of broods. M'^idely distributed in Europe, N. Africa to Egypt, West 



and Central Asia, in the warmest localities chiefly in the form tempesiiv da. 



bicoloria. Q. bicoloria B.-Bak. is unknown to me. 16 mm. Forewing silver-grey, basal area dark grey, edged by 



a darker curved line; a dark curved postmedian line, distally to which the whole surface is densely irrorated 

 with blackish; posteriorly this irroration encroaches on the median area of the wing; subterminal line obso- 

 lescent. Hindwing grey, distally dark dusted, with interrupted pale subterminal line. Madeira, one example, 

 taken high up, about the fir-tree limit. 



dearmata. G. dearmata Dietze. Very small, earth-grey, without gloss, with numerous ill-defmed transverse lines 



consisting of dark scales; the most distinct is the postmedian, especially its anterior angles ; this does not, as 

 in pumilata, start almost vertically on the costa, but obliquely outwards, leaving basewards an angle of about 

 125°. Hindwing relatively smaller than m. pmmilata, quite weakly marked. Mesopotamia: Mardin. 



coronala. 



75. Genus: Chloroclystis Hhn. 



Characters nearly as in Eupithecia, areole always simple, more or less broad, the P' subcostal vein 

 running into the costal. Early stages similar to those of Eupithecia. 



Like the preceding, this genus is chiefly Indo-Australian but it straggles into the Palearctic and 

 Aethiopian Regions. The type sjiecies, coronata Hbn., is somewhat isolated from all others in shape, resting 

 posture, pattern, genitalia, etc. and Dietze removes all the rest to a new genus, Calliclystis. The species are 

 very commonly of a green colour. 



C. coronata Hbn. (= v-ata Haw., lucinda Btlr) (13 k) is distinguished at once by the broad forewing 

 and its V-shaped black costal mark (anterior half of postmedian line). Larva in two generations on Clematis, 

 Eupatorium, Solidago, AngeUca, Crataegus, Rubus and occasionally on various other plants, eating chiefly the 

 flowers and fruit. Moth in April— May and in July, stragglers also emerging in September or later; usually 

 hibernates fully developed in the pupal shell. Widely distributed in Central and Southern Europe, Trans- 

 caucasia, N. Persia, Dharmsala, Ussuri and at Yokohama. 



chloerata. C. chloerata Mab. (13 k). Very similar to rectangulata but easily known by having the first abdominal 



segment dorsally tinged with reddish. Less variable, usually greyer, postmedian line less strongly angled 



hadenata. anteriorly, more broken up into dots. — hadenata Fnchs is a darker, almost markingless form. — Larva spun 

 up in blossom of Prunus spinosa. Moth in May, Central France to Galicia, reported also from Russia to 

 Transbaikal and from N. Japan. 



consueia. N. consueta Btlr. Extremely like the greyest, most copiously lined forms of dehiliata (13 k), sometimes 



darker; postmedian line stronger, the black vein-dots therefore less noticable; on the forewing this line curves 

 somewhat basewards at the costa (in debiliata faintly outwards, though less so than in rectangulata). Under 

 surface about as in debiliata, of which it may be the Japanese form. Ovipositor in ? well developed. 



subcinctala. C. subcinctata sp. nov. It is scarcely possible that this is a form of consueta, in spite of very close 



resemblance. Ground-colour somewhat more whitish, the strong postmedian line projecting, at the radials
