HOLARGTIAS. By B. L. Prottt. 85 



antenna", but this can scarcely refer to anything more than the strongly projecting joints or sgrrations, and would 

 help to strengther our identification. The larva, as described and figured by the same author, would appear 

 to be very similar to that of romanaria but with the dorsal area more tinged with vinous, the ventral with 

 bluish, the brown dorsal line ill-defined except on the last three segments. It was fed, in captivity, on various 

 plants, of which it seemed to prefer the flowers of Alyssum maritimum. Described from Western Spain. 

 The specimens before me are from Portugal and Southern Spain. Should it prove necessary to unite this species 

 with romanaria, isdbellaria will be its oldest name. 



G. fucata Pilng. (3 1) differs from nearly all the other forms of Glossotrophia in the more pointed forewing, fucata. 

 its distal margin being decidedly more oblique, and in the presence of a pair of strong spurs on the (J hind- 

 tibia. In these respects it agrees only with the much paler, greyer eurata Prout; see above for the differentia- 

 tion. G. fucata shows the smooth appearance of romanaria, not being strongly dark dusted. Its coloration is 

 also similar to that of the rather reddish forms of romanaria. The first line, which in romanaria and rufomix- 

 tata generally shows a marked projection behind the cell, is in fucata gently incurved in its posterior part. 

 The postmedian line is rather further from the distal margin, the grey band between it and the (strongly 

 dentate) subterminal line therefore broader; it is also in the type specimen stronger, but this may prove variable. 

 The arrangement of the dark scales on this band is scarcely so definite as in rufomixtata, certainly not so marked 

 as in romanaria. The interrupted black marginal line is immediately preceded by a very fine white line, 

 while in romanaria (see the subspecies philipparia) the pale line folloios the black marginal line. (J antennal 

 ciliation moderately strong, but the joints of the antenna not appreciably projecting. Described from a single 

 (^ from the Alexander Mountains, Central Asia. The author writes me that he has since seen a $ in the Hom- 

 BERG collection, larger but otherwise entirely agreeing. 



14. Genus: Holarctias gen. nov. 



Face flat. Eye small. Palpus moderately long, with fine, long projecting hairs below, terminal joint 

 pointed. Tongue developed. Antenna in cj with fascicles of moderately long cilia; in $ simple. Pectus and 

 femora hairy. Hindtibia in 3* with two, in 5 with four spurs. Neuration as in Acidalia. 



Unless it has any further representatives among the North American species which I have not yet 

 studied, this genus contains only a single species. It has been referred to Acidalia, but the head and leg struc- 

 ture differentiate it very strongly even from the section Pylarge, with which it agrees in the number of hind- 

 tibial spurs. This and the two genera which follow are perhaps really more ancestral than Acidalia, but they 

 seem to fall appropriately enough between that genus and Emmiltis. 



Holarctias, with its hairy clothing, is well protected against the Arctic cold and reaches high latitudes 

 and altitudes. Like some other inhabitants of the far North, it is common to the Palearctic and Nearctic 

 Regions. 



Tjqje of the genus: sentinaria, Hbn.-Geyer (Haematopis). 



H. sentinaria Hbn.-Geyer (= spuriaria Chr. — gracilior Btl.) (4i, erroneously called frigidaria). Bright, sMthmria. 

 deep reddish fulvous, more or less strongly suffused with dark fuscous, at least in the basal area of the hind- 

 wing; most commonly the distal half of the forewing and to a less degree of the hindwing remains nearly 

 free from suffusion, but sometimes the clear coloration is restricted to a narrow area between the median 

 and postmedian lines. Lines dark fuscous; first line of forewing bent near the costal margin, approaching the 

 median line posteriorly, very frequently altogether lost in the dark suffusion ; median line rather thick ; postme- 

 dian only slightly sinuous. Cell-spots usually obsolescent. Fringes flushed with vinous. Under surface clearer 

 fulvous, usually without dark suffusion, the darkest specimens, however, suffused from the base to the 

 median line; median and postmedian lines, and usually the discal spots, shai-ply defined; sometimes there are 

 traces of the first line in the posterior part of the forewing. A very easily recognized species, in spite of its 

 variability in coloration. The type form, so far as I know, does not occur in the Palearctic Region, but inhabits 

 Labrador and the Rocky Mountains of Canada and Colorado. As it was the only form available for figuring, 

 and Staudinger has reckoned Labrador to the Palearctic Region we represent it here. — rufociliaria Brem. ru/ocUiaria. 

 (= rufularia Ev. nee H.-Sch. = rufinaria Stgr.) is on an average decidedly larger, the colour is brighter (al- 

 most as in Ptychopoda serpentata Hufn.), the lines and discal spots of the upper surface more distinct, as there 

 is either no dark suffusion or at most some suffusion (not very intense) in the basal part of the wings. Distri- 

 buted in Siberia. I have seen specimens from Amurland and the Kentei Mountains. According to Stau- 

 dinger the examples from N. E. Siberia are smaller, in this respect approaching the American type. — rufi- mjinnlarm. 

 nularia Stgr. from the highest altitudes in the Sajan district, is unknown to me in nature. It is also smaller
