378 BOARMIA. By L. B. Protjt. 



pulverosu. March. Distributed in N. India, a sLniilar form at Chungking, Huang-mu-shang and Ta-chien-lu. — pulverosa 

 Warr. is rather narrower wuiged, dull grey, powdered all over with olive fuscous. Stalk of 1st — 2nd sub- 

 costal well separated from that of 3rd — 5th. Kulu, common. 



excellens. B. excellens Btlr. (= incertaria Stgr.) (21 h). In general larger than the 3 preceding, especially the $, 



which has a very stout abdomen but not (or scarcely) extended ovipositor. Postmedian line more dentate and 

 smuous but never very sharply expressed, the dark marks on and distally to it behmd the 3rd radial strongly 

 developed. The ground- colour- varies from dirty white (in the $) to dirty light grey or dull pale fleshy brownish. 

 Japan and Ussuri, about the end of May. 



conoinnaia. B. concinnata Wihman is very distinct in the irregidarly crenulate distal margin of the hindwmg 



and the strongly excurved antemedian line of the forewing; postmedian Ime remote from distal margin, with 

 black teeth on the veins in its anterior part, slightly mcurved behmd the 3rd radial of the forewmg. The name- 



interrupki: type is whitish, only slightly mixed with brown. Hakodate, m April. — ab. (?) interrupta Wihman (21 h) is 

 rather sm'&.ller, much more brown, only a part of the median area of forewing and the basal and costal parts of 

 hindwing remaining paler. Toldo, in April; only one known. 



consonaria. B. consonaria Hbn. (= tetragonaria Curt.) (21 h) differs from the crepuscularia group m its tone of 



colour as well as in the shape and position of the postmedian line. The $ is much more whitish than the (J 

 and shows a stronger, darker quadrate spot between the postmedian and subterminal lines of the forewmg. 

 nigra. — ab. nigra Bankes is unicolorous blackish except a very small patch of white distally to the cell. Kent. — 

 Egg longitudinally ribbed, yellow, marked with orange red. — Larva elongate, transversely wrinkled, with 2 minute 

 warts on the 8th abdominal: yellowish brown clouded with grey and with reddish. On birch, beech, oak, etc. 

 The pupa hibernates and the moth appears in May. Central Europe, S. E. Siberia and Japan. 



farracearia. B. farracearia Leech (21 h) is quite unlike all the other Ectropis species, the coloration resembling that 



fuliginaria. of granitalis sublimis, though the broad wings more recall Chiophos. \\ . Chma. — fuliginaria Leech has the 

 suffusions darker, less blue (more smoke-coloiu'), somewhat more extended. Central Chma: Ichang. Only one 

 example known. 



irhiis. B. tristis Btlr. (25 g) is also very distinct, not only in its blackish smoky wmgs, with white admixture 



m parts, especially on the hindwmg. but also in the absence of the fovea (genus Abaciscus Btlr.). Dharmsala, etc. 



praeclarata. B. praeclarata Pi'mg. Rather smaller and narrower-winged than extersaria, antenna more slender, 



hindtibia of (J with strong yeUow hair-pencU. Wings white, forewing with brown basal patch, costal spot oppo- 

 site the cell-spot, larger subapical costal spot, weak, nearly straight median Ime (shade) and some shading to 

 the subterminal line. Hindwing with discal dot, otherwise weakly marked. Koko-Nor. 



extersaria.. B. extersaria Hb7i. (= liu'idata Bkh. nee Httfn.) (21 h). Whitish brown, very densely dotted and strigu- 



lated with dark brown, cell-spot rather large, median shade of forewing usually strong, a very characteristic 



(though in size variable) white spot (expansion of the subterminal Ime) in middle of distal area. Distributed 



inalbata. in Central Europe. — ab. inalbata Ob. has the black lines rather approximated, the white dusting and white 



tornelseni. subterminal obsolescent. — ab. cornelseni P. Hoffmann is glossy black Avith white band distally to the postmedian 

 and mcomplete white subtermmal. — In S. E. Siberia and Japan extersaria is represented by a somewhat 



ohscurior. smaller, darker race, obscurior Stgr., in which the white distal spot is generally very small. — Larva elongate, 

 with slight dark-coloured dorsal prominences on the 2nd and 5th abdommals; brown, often tinged with green, 

 dorsum with pale quadrate spots, sides with very dark blotches. On oak, birch and other trees. The pupa 

 hibernates and the moth fhes m May — June. 



eoatipuncia- B. costipunctaria Leech (21 h). Ground-colour quite different, pale violet-grey, less uniformly dotted 



''*^' and strigulated, usually with a blackish spot at hindmargin of forewing uniting the median and postmedian 

 lines, the pale distal spot ill-defined and inconspicuous but reaching the distal margin. Japan: Oiwake. 



opei-iaria. B. opertaria Leech (21 h). Slightly larger than costijmnctaria, much more mixed with brown, leavmg 



only traces of the violet-grey colour in the median area: the dark markmgs much less developed. Perhaps not 

 really distmct. Japan. 



petiosa. B. petrosa Btlr. (21 i) is a larger and broader-winged species, hindwmg with more strongly crenulate 



distal margm than in any precedmg Ectropis. Bright ochreous brown, dusted and clouded with more reddish 

 brown, all the usual lines present, though not very sharp, the postmedian dentate, nearly parallel with distal 

 margin. Japan. 



iristaria. B. tristaria Leech (21 i). Wmgs slightly narrower, the hmdwmg not appreciably crenulate. Dull dark 



brown-grey, the lines still less prominent than in petrosa. Kiukiang, Central Chma.
