44 TANAOTEICHIA; SOMATINA. By L. B. Protjt. 



observed ill a few Larentiinae: the complete separation of the 5. subcostal from the others. Thus the genus, 

 though evidently an offshoot of Bhodostrophia (Section A), has actually only a single areole, formed by the 

 anastomosis of the 1. subcostal with the 2. Created for the reception of a single species, of which I have 

 only seen two examples, so that I cannot say quite positively whether the peculiar neuration is constant; 

 if not, the genus must sink to the preceding. Christoph, who placed his species with a query in Fidonia, 

 did not notice any abnormahty; thenumber of hindtibial spurs m the ^ is not known to me, as Christoph's 

 and Warren's specimens and one in the British Museum are all $. 



solitaria. A. solitaria Chr. (= albiclathrata Wmr.) (7a). Brown, with the costal margin of forewing broadly pale 



ochreous, the veins also pale ; forewuig with three pale transverse lines, the middle one broadened into a band 

 anteriorly and containmg the dark, elongate cell-mark, the outer sinuous, running to the anal angle, distal 

 margin pale; hindwing ochreous, dusted with brownish posteriorly, median line faint, submarginal and marginal, 

 as well as the cell-spot, as in forewing. Transcaspia and Hi district, apparently scarce and local. 



3. Genus: Tauaotricliia Warr. 



Nearly related to Rhodostrophia, the forewing rather broader than in most Rhodostrophia-fovms, about 

 as in vinacearia sinensis and philolaches. Hmdwing with distal margin rounded. Palpus rather short, upcurved. 

 Hindleg in (J without median spurs and with only a single well-developed terminal, the other greatly abbrevia- 

 ted, perhaps sometimes wanting; a strong hair pencil from femoro-tibial joint and some short, compact tufts 

 arising near the spurs, looking, without close examination, like two additional spurs . $ with 4 spurs. Second 

 subcostal of forewing arising from the cell, though sometimes at the same point with the stalk of the 3. — 5. 



The type of the genus, prasonaria Sivinh., does not occur in the Palearctic Region. The species thus 

 identified by Leech is new, and is described below. 



orientis. T. orietitis sp. nov. (= trilineata Leec/t, nec Warr.) (la). Smaller than prasonaria, apex rather less acute, 



ground-colour light yellowish bro-mi entirely without red admixture, on the other hand fmely and minutely 

 dusted with fuscous. Lines fuscous; the first further from the base than in prasonaria, excurved not straight; 

 the second followed by distinct fuscous shading; the third more gently and regularly bisinuate, without the 

 strong, smgle posterior curve of prasonaria; distal area of forewing except at apex shaded with fuscous; 

 discal spots wanting. Underside mth the lines fine, forewing from base to beyond middle, except at margins, 

 clouded with fuscous. Che-tou, W. China, 3360 m, July or August, 1890. May possibly prove a form of the 

 doubtful "Rhodostrophia" hisiniiata Warr., mentioned above. 



4. Genus: Soiuatiiia Guen. 



Palpus m both sexes short or quite moderate, the terminal joint not elongate. Antenna in ^ usually 

 with fascicles of cilia, which only exceptionally arise from (short) pectinations. Hmdtibia in ($ without spurs, 

 usually shortened and thickened and with strong hair-pencil; in $ with 4 spurs. Forewing with areole double, 

 the 2. subcostal stalked with the 3. — 5. Hmchving with the 2. subcostal and 1. radial separate or very 

 shortly stalked, 2. radial sometimes arising rather near the anterior angle of cell, as in the Hemitheinae. 



Early stages apparently unknown. 



Concerning the geographical range of this genus I am unable to give exact information at present, 

 as I cannot delay the present work until I have comjDleted my survey of the allied forms of the other con- 

 tinents. All the four great regions produce forms with the same essential structure as regards palpi, spurs 

 and the double areole, but there is a good deal of divergence in the antennae and some details of leg struc- 

 ture and of neuration, which may or may not prove to be of generic value. I have in the mean time gi- 

 ven to Guenee's wellknoAvn genus a rather wide extent, including in it several species which Hampson 

 would have called Erythrolophus. He overlooked in his "Moths of India" that the type species of the 

 genus Erythrolophus has a long terminal joint of the palpus, especially in the 9 ; while his other distinction, 

 the point of origin of the second radial of the hmdwmg, only applies to a few Somatitm species and would, 

 indeed, have excluded the type of the genus! At least it can be stated that the most typical species of the 

 genus are Indo-Australian, that it is wantmg in Europe, but that a few aberrant stragglers extend into Pale- 

 arctic Asia. Dithalama Meyr. may be a synonym, and has been so regarded by Turner; but in its type-species 

 the 2. subcostal of the forewing arises from the cell, and there are other slight differences. I mention the name 

 because Meyrick and others have applied it to indicataria Walk., m which the 2. — 5. subcostals are stalked. 



indicaiaria. S. indicataria Walk. (5 a). White, marked with grey and on the forewing with a thick brown median 



line curving round the elongate, thick black cell-mark, but not or scarcely reaching the costal margin; inner
