OULOBOPHORA. By L. B. Prout. 



the middle segments, by other red markings. It feeds on Actaea spicata in July, at first in the unripe berries, 

 later between loosely spun leaves. Pupa light brown, head and anal end somewhat darker. The moth emerges 

 in April and May. In Europe it has a local distribution from Bavaria to the Ural and in Asia it extends 

 across Siberia to the Ussuri. 



inuscigera. A. muscigera Butl. {= olivaria Leech) (12 b). Of this species I have only seen two ?? but on account 



of its long palpus, biangulate discocellulars, etc., I have no doubt it should be referred to this genus although 

 its shape is more that of Nothopteryx. Yokohama. 



seiiata. A. sertata Hbn. (= appendicularia B.) (6 f) differs from the other species of Acusis in its much shorte 



palpus, which is formed about as in Nothopteryx. Wings dirty white (in freshly bred specimens greenish), 

 marked with brown-grey. Hindwing very weakly marked above, beneath whiter, with distinct cell-spot followed 

 in the middle of the wing by a strongly curved line. Variable in the strength of the markings which (as in 

 virefata) appear blacker in worn specimens. The colouring in our figure has not come out satisfactorily. — 

 fmnidata. fumidata Trti. & Verity is according to the description a heavily marked form with ground-colour smoky 

 brown, not whitish. Terme di Valdieri, Maritime Alps. — Larva yellow-green with white subdorsal lines and 

 blackish head, feeding on sycamore (at first on the buds) in early spring, full-fed in May. Pupa compact, 

 brown, with 2 cremastral points. Imago in September — October, local in Southern Central Europe 

 hibernates. Statements that the moth does so are not substantiated. 



The egg 



neurogram- A. neurogrammata Pilag. I gather from the figure and description of this species that it is probably 



mata. closely related to polystictaria Hmpsn. from Yatung, Tibet, possibly even a form of it, with the veins more 

 strongly black-marked. If so, it is referable by the neuration to Acasis though the palpus is not much longer 

 than in sertata. Expanse about 37 mm. Forewing ash-grey with a slight tinge of browm, the discal dot small 

 and weak, close beyond it a curved dark line (excurved in anterior half, incurved in posterior) accompanied 

 by brownish shading which fades out distally; the veins in the distal half of the wing and in part in the 

 median area strigulated and dotted with black. Hindwing whitish grey, unmarked; the lobe as in carpinata. 

 Forewing beneath brown-grey, both wings with fine discal dot, otherwise unmarked. Koko-Nor, 2 cfcT. 



hellaria. A. bellaria Leech ( 1 1 a). Much smaller than muscigera, somewhat intermediate in shape between Ihat 



species and virefata. Distinct from both in the restriction of the green colour, the distal area from the S^"* 

 radial to the hindmargin, sometimes also the central area, being strongly sufl'used with whitish; in any case 

 a white spot, as in muscigera, remains on the middle of the hindmargin. Further distinguished by having a 

 distinct dark band midway between the subbasal and antemedian lines. Under surface pale, especially on the 

 hindwing. Japan; Ussuri. I have only seen Leech's types; in the cf the 2"'' subcostal of the hindwing is 

 separate, in the ? short-stalked. 



24. Genus : Olllobox>llora Stgr. 



Face somewhat prominent, tufted. Palpus quite moderate, rough-scaled. Antenna in both sexes simple. 

 Hindtibia in cf with hairpencil, in both sexes with all spurs. Forewing with distal margin strongly bent or 

 almost angled in the middle, anteriorly often slightly concave, posteriorly slightly concave and strongly oblique; 

 areole double. Hindwing small, in the o^ with the submedian veins and the 2"'' median wanting, but with the 

 basal lobe extremely ill-developed; in both sexes with the costal anastomosing with the cell; discocellulars 

 biangulate. 



Only two species are known, extending from the Balkan Peninsula to Syria. 



internata. 0. internata Piiny. (:= macedonica S^^rr.) (8 a) is distinguished by the more extreme shape of the fore- 



wing, the almost straight proximal edge of the median band, the greater breadth of the band itself, its brighter 

 pinkish-brown colour and other characters. Only known from Asia Minor. Macedonia and Greece. 



externata. 0. externata H.-Sch. (6f). Usually darker than internata, but with the median band varying between 



reddish brown and blackish brown, its proximal edge incurved, its distal oblique at the costa, somewhat pro- 

 minent in the whole exterior part, marked with strong blackish dashes on the veins; a rather conspicuous 

 whitish blotch occupies the middle of the distal area. Turkey, Bulgaria, Greece, Asia Minor and Syria.
