320 HYPERYTHRA; SYRRHODIA; ANAGOGA. By L. B. Prout. 



27. Genus: Hyperythra Guen. 



Face smooth, with a slight tuft at lower extremity. Palpus rather long. Antenna in ^ bipectinate. 

 Pectas hairy. Forewing in ^ with fovea; 1st subcostal free, 2nd stalked with 3rd — 4th, usually arising 

 just beyond 5th. Hindwing with distal margm crenulate, commonly somewhat cut away at apex; cell extre- 

 mely short ; costal margin in ^ greatly expanded, a strong tuft of hairs arising from base of cell and lying 

 in a groove along upper surface anteriorly to the cell. 



Indo -Australian. All the species are very closely related, if not races of a single very variable species. 



lutea. H. lutea Stall (= flavaria F., limbolaria Guen.), founded on a $ from Java, but widely distributed 



throughout India, etc., has been taken at Dharmsala, but can scarcely be regarded as a Palearctic species. 

 It is very variable, the $ bright yellow, the ^ strongly suffused with pink and more mixed with fuscous, 

 ennomaria. altogether much more variegated. — ennomaria Guen. (19 c) is distinguished by its much more uniform pinkish 

 brown ground-colour, both surface in the (^ almost entirely without yellow admixture, the $ showing some 

 yellowish beneath. The underside shows a conspicuous triangular whitish patch on distal margin close to 

 the apex of the forewing, which is less well defined in the name-type. Dharmsala, etc. 



28. Genus: Syrrliodia Hbn. 



Very closely akin to Hyper yihra, but without the abnormally short cells, expanded costal margin and 

 long hair-pencil. The secondary sexual modifications vary in different groups and are sometimes very slight. 

 The only species included m the present volume forms the type of the section Tycoonia Wan., the ^ with 

 a small patch of hair on the upperside of the forewing, placed on the fold at about one-fourth from the base. 

 The genus is widely distributed — India, Africa, S. America. 



ohliqua. S. obliqua Wan. is very closely like the Indian phoenix Swinh. (figured in Vol. XII). The ^ can be 



distinguished by the scent-patch on the forewing. The postmedian line of the forewing is remarkably straight, 

 the median line more slender than in phoenix and slightly oblique, thus nearer to the postmedian at the costal 

 than at the posterior margin; dark apical spots of hindwing weak and diffuse. Described from ,, Japan". I have 

 before me 2 ^(^ from Omei-shan and a 2 from Kwei-chow. 



29. Genus: Aiiagoga Hbn. 



Face somewhat protuberant below, shortly rough-scaled. Palpus moderate, rough-scaled. Antenna 

 in cJ bipectinate, with rather long branches. Forewing rather elongate, apex pointed; fovea wanting; 1st 

 subcostal anastomosing or connected with costal; 2nd arising from 3rd — 5th, or rarely from 1st, anastomosing 

 with 1st. Hindwing moderately rounded, costal approximated to cell to one-half, 2nd subcostal often from 

 end of cell or even very shortly stalked. 



Larva elongate, twig-like, the head cordiform, the 5th abdominal segment with a strong transverse 

 protuberance, the 6th with smaller protuberances. 



A small genus, chiefly (perhaps exclusively) Palearctic and Nearctic. 



pulveraria. A. pulverafia L. (= diffusaria Walk.) (15 h). Variable, but always showing more or less of a reddish 



tone, with no markings except the rather straight antemedian and posteriorly strongly incurved postmedian 

 passelli. lines of the forewing. The median area in the name-typical form is darkened. — ab. passetii Th.-Mieg (= sa- 

 margincpur- turaria Wagner) is violaceous grey instead of reddish brown, the median band sharply expressed. — ab. margi- 

 puraria. nepurpuraria Bastelb. (25 a) is deeper red, the median area of forewing and basal half of hindwing more orange-, 

 the rest more purple-tinged, lines thick, antemedian rather curved, postmedian less broad anteriorly than in 

 unicolor. the type. Rather small and round-winged. Rheingau. — ab. unicolor Hirschke has both wings uniform 

 gadmmsia. brown, dark-dusted, without lines or band. — gadmensis Ratzer is a rather small, brighter (yellower) brown 

 form from Switzerland (Gadmenthal), with the median area almost or quite concolorous, the lines remaining. 

 violacearia. — violacearia Graeser (15 h), from Amurland, is a very small form, coloured nearly like marginepurpuraria, 

 which must perhaps sink to it, but the thick lines are described as dark violet and it is not indicated that 

 jciponica. their form differs from the normal; compare, however, the following form. — japotlica Btlr. (= violacearia 

 Herz, ? Graeser) is a small race, or possibly distinct species, from Japan and Korea, bright deep red-brown, 

 the median area as broad posteriorly as anteriorly, not differentiated in colour, the lines which bound it deeper 

 red brown, the postmedian only projecting a little in the middle. Line on hindwing continued nearly to the 

 costal margin, straighter than in marginepurpuraria, which also shows this peculiarity. — Egg dark red through- 

 out, or with more or less confluent dark red spots, the reticulation very fine and shallow. Larva reddish brown 

 or purplish grey, mottled with yellowish brown; on birch, oak, sallow, etc. The pupa hibernates and is rather 

 elongate, red-brown, pulveraria flies in April — June, a partial 2nd brood in July^ — August. It has a wide 

 distribution in Central and N. Europe, Siberia, etc.
