 RHYACIONIA, Hb. [LEP. TIN.].

OLETHBE UTIDAE. 



241. RHYACIONTA Hb. 



= RETINIA On.; ^ EVETRIA (Hb.) Meyr., Stgr-Rbl. 



1844"1. Ehyacionia logaea, sp. n. 



= Betinia *duplana (nee Hb.) Brt. Br. Lp. XI. 40-1, Pf. 476-2 (1906). 

 Evetria duplatia (p.) Meyr. HB. Br. Lp. 471 sp. 5 (1895). 



Antennae ^ biciliate 1, cinereous, annulate with fuscous ; 9 fuscous. Palpi 

 fuscous. Head dark ferruginous, mixed with fuscovts ; face fuscous. Thorax 

 dark fuscous, with some admixture of cinereous and ferruginous. Forewings 

 elongate, pointed, costa almost straight, termen obliqiie ; fuscous, some of the 

 scales tipped with white and forming obscure cinereous fasciae, ferruginous 

 toward the apex and termen, but not at the tornus ; the dark ground-colour 

 extends along the costa to vein 9, or beyond, along the dorsum to the tornus, 

 and in the disc to the end of the cell, thence becoming ferruginous, with some 

 adraixtui-e of fuscous toward the termen; the base of the wing is speckled 

 transversely with cinereous ; a cinei'eous fascia at one-fourth, widening out- 

 ward on the cell, is succeeded by a similar fascia angulate outward to the 

 discoidal, with a third crossing almost to the tornus, some paler transverse 

 scaling occiirs also before a preapical costal spot ; cilia pale cinereous, with a 

 fuscous dividing line near the base, and paler lines toward their tips. Exp. al. 

 14-17 mm. Hindwings fuscous ; cilia paler, with a dark dividing line toward 

 their base. Ahdome7i fuscous, banded with cinei-eous. Legs cinereous, tarsi 

 spotted with fuscous. 



Type $ (56717) ; ? (62269), Mus. Wlsm., British Museum. 



Hah.: Scotland: elgin : Forres, IV. {W. Salvage, 1890, 1891; 

 W. Beicl, IV. 1891 ; H. Mc Arthur, 1892, IV. 1893). Fifty specimens. 

 [Mus. Wlsm. 8 (56717, 62047-52, 62269) ; E. South ColL 1 (Dmt. 

 6458) ; B. A. Bower Coll. 12 (Drnt. 6469-80) ; R. Adkin Coll. 25 

 (Drnt. 6481-6505) ; N. C. Rothschild Coll. 4 (Dmt. 6521-4)]. 



Closely allied to duplaiia Hb. and posticana Ztst., but the much 

 longer antennal ciliations of the ^ will at once separate logaea from 

 these species. B. posticana has an ochreous head, and is a broader- 

 winged insect than duplana or logaea, and the hindwings are distinctly 

 less pointed. The Type ^ of logaea is the specimen figured as " duplana* 

 by Barrett (Pf . 476*2) ; the 5 is similar, but smaller than the ^ , and 

 somewhat more distinctly marked, it is however not so clearly and 

 neatly fasciate as is the true duplana Hb., and the direction of the
