RHYACIA. By Dr. Corti and Dr. M. Draudt. 
pallida, named: — pallida Hofjm. (= pallescens Stephan). Such specimens are described from Styria and the district 
around Glatz. 
ononensis. Rh. ononensis Brem. (= scaramangae Alph.) (Vol. 3, p. 50, pi. lib and 12 d). The two names are 
certainly synonymous. The illustration on pi. 12 d is quite unrecognisable, whilst that on lib is fairly satis¬ 
factory. We are giving a better illustration here (12 d). 
praecipua. Rh. praecipua Stgr. on the other hand is not synonymous with ononensis. It is a genuine species, which we 
are illustrating here (12 d). It is smaller and has narrower wings than ononensis, is of much duskier colouration, 
has no pale streaks on veins and only the median nervure and a wide costal streak are slightly paler. The 
subterminal line is scarcely discernible. Other markings however are fairly similar. Hindwings rather paler. 
Mongolia, Siberia, the Amur territory. 
lasciva. Rh. lasciva Stgr. (Vol. 3, p. 50, pi. 12 d) cannot be recognised from the illustration in Main Volume. We 
are illustrating a fine specimen (12 c) from Margelan in Turkestan. 
Rh. juldussi Alph. (Vol. 3, p. 50, pi. 11 b). The illustration fairly represents the species. 
Subgenus: Pseudospaelotis McD. 
conjuncta. Rh. augur F. (Vol. 3, p. 49, pi. 10 g). — ab. conjuncta Schille denotes a fairly common aberration in 
ioibolskensis. which a black longitudinal streak extends from reniform st igma to the posterior transverse line. — tobolskerssis 
Shelj. is much darker black-grey with indistinct transverse lines and white fringes to hindwings. Tobolsk (W. 
nigra. Siberia). — nigra Vorbr. is a dusky, almost blackish form described from the Gotthard and also occurring 
in the Tyrol. 
haruspex. Rh. haruspex Le Gerf. Forewings rufous; anterior transverse line faint, black, excurved in and below 
cell; stigmata with black circumscriptions, orbicular stigma small, inclined to be oval, claviform stigma 2 mm 
long and quite black, no central shade, the posterior transverse line forms a blackish shadowy band, that 
is extended outwardly on the veins forming projecting points. In place of a subterminal line, there are whitish 
dots with short blackish sagittate marks anteriorly. Hindwings blackish grey, somewhat paler at base. Wing 
expanse: 39 mm. Described from 1 $ from Morocco. 
bipariita. Rh. bipartita Graes. (Vol. 3, p. 51). Corti was in doubt as to whether this species should he classified 
here. In the Main Volume it was placed after defessa Led. Besides the type, only one other $ specimen is 
known to Filipjev, who would prefer to classify same near brunnea. According to Warren it is certainly 
a Rhyacia. From Sutshan. 
Subgenus: Actebia Steph. 
fennica. Rh. fennica Tausch. (Vol. 3, p. 47, pi. 10 g). The illustration was poor, we are therefore giving a better 
illustration (12 b). This fine species is remarkable on account of its sexual dimorphism. In the $ the ochreous 
yellow inner marginal stripe is absent. Switzerland must be deleted from the area of distribution. Vorbrodt 
is very doubtful and says that questionably many years ago 2 badly worn specimens were reported to have 
been captured in Aargau and on the Wengernalp. On the other hand Petersen states that the species is 
unicolor a. known to occur at Reval. Kozhantschikov describes an — ab. umcolora that differs through the absence of 
the pale streak on inner margin of forewings; as unfortunately the sex is not indicated, it may be assumed 
that this is merely the normal $. 
praecur- Rh. praeeurrems Stgr. (Vol. 3, p. 56, pi. 13 g). The illustration in Main Volume is not satisfactory and 
ren.s. we are giving a better illustration here (12 e). 
jlavomacu- Rh. praecox L. (Vol. 3, p. 56, pi. 13 g). The form — flavomaculata Graes. is now illustrated (12 e) from 
lata. a typical specimen from Yokohama. 
adomata. Rh. adornata Corti ined. (12e). A new species that should be classified here. Body and forewings 
brownish grey interspersed with coarse greenish white scales. These are most dense on head and patagia. Trans¬ 
verse lines are undulate and dentate, double, intertilled with paler scales; orbicular, reniform and claviform 
stigmata are large with black circumscriptions and greenish grey-white centres. Costa somewhat darker: 
subterminal line whitish with long black sagittate marks anteriorly. A distinct black marginal line; posterior to 
a yellowish white base line, fringes are checkered. Hindwings grey-brown, rather more thinly scaled and 
paler at base and in disc. A distinct black base line to fringes. From 1 <$ from Ta-tsien-lu. Type in the 
collection of Corti. 
dizyx. Rh. dizyx Pglr. (Vol. 3, p. 39, pi. 8 f ) . The illustrations are not bad. The sexes diverge considerably. 
We are giving a fresh illustration of the <§ (12 e) so as to show the relationship or affinity to the previous 
species and in accordance with the intention of Corti.
