294 SINNA; GABALA; SIGLOPHORA. By W. Warren. 



whicb'the subfamily name is taken; in these the larvae are said to^be semi-loopers, with the first two pairs of 

 prolegs aborted, and forming a cocoon under ground for pupation. 



1. Genus: ft i mi a Walk. 



Tongue developed; frons smooth; palpi obliquely upturned, closely scaled, the third segment nearly 

 as long as second; antennae of (J ciliated; thorax and abdomen smooth, without crests; forewing ample, 

 with blunt apex and curved even termen; the retinaculum bar-shaped in $. Type S. calospila Walk. 



extrema. S. extrema Walk. (= reticularis Fldr., ornatissima Alph.) (53 g). Forewing orange; a white band from 



base of costa to before middle of inner margin, its upper edge sinuous ; a subbasal white spot on costa and another 

 beyond in and below cell; an oblique white bar from costa before middle, a spot on median nervure, and a patch 

 on inner margin with a hook on its inner side; two discoidal spots, spots beyond upper and lower angles of 

 cell, and a spot below lower angle ; an oblique wedge shaped outer patch from costa, a point on vein 6, a curved 

 mark between cell fold and vein 2, more or less forked below, and a conical spot on inner margin confluent 

 with the white on termen ; a large apical white patch and narrow terminal band with waved inner edge ; black 

 spots on costa before apex and below vein 7, the latter oblique ; a terminal row of 5 black spots, that at 

 apex larger and that above tornus bar-shaped; hindwing white, sometimes tinged faintly with brownish; the 

 jentoni. insect varies ha intensity of coloration; ■ — in ab. fentoni Btlr. (53 f) the forewing is pale yellow, the white mark- 

 ings amplified, the yellow reduced to narrow meandering bands, the outer markings coalescing into an unbroken 

 clara. band, the terminal black marks reduced ; ■ — in ab. clara Btlr. (53 g) the yellow is still paler with its area smaller, 

 [unicolor. the terminal area almost wholly white, the black markings wholly or partially absent; — lastly, in unicolor 

 Wilem. both thorax and forewing are entirely white. Ussuri, E. Siberia; Japan; Central and Western China. 



2. Genus: Gabala Walk. 



Tongue slight; frons smooth, with a ridge of scales above; palpi obliquely upturned, the second segment 

 long, with a tuft of hair on upper side before end, the third equally long, with a tuft of hair near extremity ; 

 antennae of $ almost simple ; thorax densely scaled, the metathorax with low rounded crest ; the $ with lateral 

 fans of large scales; forewing with costa strongly arched at base, the apex blunt, the termen even, slightly 

 curved; veins 8, 9, 10 stalked; 11 from cell; hmdwing with termen almost straight to vein 2, then excised 

 to tornus; veins 3, 4 shortly stalked; costal and subcostal anastomosing to middle of cell; retinaculum in $ 

 formed by a tuft of hair from below median nervure. Type G. polyspilalis Walk. 



Sect. II. The abdominal fans of <$ small, with a tuft of long hairs below them; 

 excision of hindwing slight; no fringes of hairs on upperside. 



argentata. G. argentata Btlr. (53 g). Forewing bright rufous; basal area with numerous silvery white spots de- 



fined by blood red, the subbasal and inner spots larger ; a pale striga on discocellular ; an indistinct double dark 

 outer waved line, concave outwards from costa to vein 6, indented on discal fold, and below vein 4 incurved 

 to lower angle of cell; a patch of pale and silvery white spots reticulated with red in apical area; 3 white 

 subterminal dots between veins 5 and 2, preceded by a dentate line and edged with red; terminal line dark; 

 fringe rufous and brown; hmdwing white, tinged with yellow beyond cell; the termen rufous from apex to vein 

 suffusa. 2; • — in ab. suffusa ab. nov. (= ab. 1 Hmps.) (53 g) the forewing and thorax are suffused with fuscous brown; 

 rufUota. — in ab. rufilota ab. nov. (= ab. 2 Hmps.) (53 g) the suffusion is rufous; the ab. flavata ab. nov. (= ab. 3 Hmps.) 

 flavata. (53 g ) h as fae thorax and forewing with the spots pale yellow, the costa towards apex and the fringe reddish 

 yellow. Japan, Corea, Hongkong. 



3. Genus : Sig'lophora Btlr. 



Tongue well developed ; frons smooth, with a ridge of scales at top ; palpi obliquely upturned, smoothly 

 scaled, the third segment nearly as long as second; antennae of <$ simple, lamellate; thorax and abdomen smooth; 

 a slight metathoracic crest; tibial spurs long; forewing with apex blunt, the termen curved and even ; veins 8, 9, 10 

 stalked; hindwing with termen excurved at middle, truncate towards tornus; veins 3 and 4 stalked. Type 

 8. bella Btlr. 



Sect. I. A ridge of metallic scales between antennae. 



Subsect. A. Forewing of cj with large glandular swelling at middle of costa on un- 

 der side., with tufts of curled hair round it on upperside, distorting the neuration. 

 ferreilutea. S. ferreilutea Hmps. (= ferruginea Leech) (53 g). Forewing bright yellow; a bloodred dot at base 



and waved subbasal line ; inner band with waved edges filled in with bloodred ; a conical patch on mner margin 

 at middle, with a yellow spot on it; an oblique diffused band from middle of costa to lower angle of cell, becom- 

 ing confluent there with the red terminal area which is suffused with fuscous, its inner edge curved from 

 termen below apex to inner margin, the costal area remaining yellow ; outer line red, oblique and dentate to
