LARENTIA. By L. B. Prout. 
Forewing with the termen moderately oblique; whitish grey with reddish irroration, the markings grey-brown 
mixed with red; basal patch very obliquely bounded; median band sharply defined, parallel-sided, its boun¬ 
daries sinuate, but far less irregular than in the genotype. Hindwing whiter, distally with red-brown suffusion, 
beneath with the cell-dot much strengthened. Szechuan: Ta-tsien-lu and Sunpanting. 
K. avulsa sp.n. (7 d). Near purpureotincta in structure and markings, antennal joints of the less avufoci. 
projecting, ciliation minute, hindwing with the shape perhaps a little more extreme. Coloration of forewing 
browner, more uniform, without red admixture; basal patch and median band somewhat infuscated, the rest 
of the wing merely with very slender and inconspicuous rippling; median band narrow, its distal edge with 
small and irregular indentations at all the veins; subterminal line traceable but (especially posteriorly) indis¬ 
tinct; terminal line stronger than in purpureotincta. Hindwing pale, but not quite so white as in purpureo¬ 
tincta. Underside also with stronger terminal line than in that species. Chinese Tibet: Yaregong and Yargong 
Zambala (R. P. Soulie), 5 Szechuan: Ta-tsien-lu, 3 type in the British Museum ex coll. Oberthur. 
The poor $ from Yatung, mentioned in Vol. 4 (p. 165) under Kuldscha oberthuri, is evidently very close to avulsa. 
K. pantophrica sp. n. (7e). Rather larger than avulsa , forewing looking a little more elongate, an- pantophrica. 
tenna slightly intermediate towards that of purpureotincta. Forewing with median band as narrow as in avulsa, 
but much more regular, it (and indeed the whole of the markings) maintaining a course closely parallel with 
the termen; a sharply contrasting whitish area betw r een the dark median and the less sharply defined dark 
distal area; both the dark and the pale areas rippled with fine lines; terminal black line strong. Hindwing corres¬ 
pondingly somewhat more variegated with white than in avulsa. Ta-tsien-lu, 6 1 £ in the British Museum. 
5. Genus: liarentia Tr. 
(See Vol. 4., p. 157 ; Vol. 16. p. 88.) 
A strict dividing-line between this genus and the somewhat heterogeneous assemblage which I have 
called Cidaria section Colostygia (Galostigia olim) has not yet been found, and even the equally heterogeneous 
section Goenotephria can, in the genitalia, show a pretty obvious approach to L. clavaria (e. g., G. amelia). In 
dealing with the non-Palaearctic fauna, I have had to give Larentia, as also Perizoma, a provisionally wider 
scope, but in the present volume (also “provisionally”) I have attempted to conserve the general plan of Vol. 4, 
and have only added to the genus Larentia an Ortholitha- shaped species which would seem manifestly out of 
place in Cidaria. 
L. clavaria Haw. Kxobloch notes the remarkable fecundity of this species in comparison with most clavaria. 
Larentiids of which the egg-laying habits are known. One $ laid 290 eggs, another nearly 200. He also notices 
the exceptional stickiness of the excrement of the larva. — datinaria Oberth. (7 e). As the figure given in Vol. 4 datinaria. 
was not altogether satisfactory, Dr. Wehrli has kindly lent the model for a new one; he has also given some 
details of the variability of this well-defined African race, as exhibited in the Oberthur collection. The type 
remains the only example known from Kef, but a homogeneous series from Lambese enables one to get a good 
idea of its characters. Few examples are so grey or so weakly marked as the type, but even when the basal 
and median areas are more brownish grey (bounded by darker grey), the distal area remains pale, a contrast 
to the dark distal area of clavaria (Vol. 4, pi. 6 i), and the subterminal is decidedly less deeply dentate than in that 
form, the enclosed dark spots on its proximal side consequently different in shape and generally more conspicuous; 
width of median band and form of its boundary-lines variable. Also known from Batna (Tring Museum etc.), 
from Tunis, Malta and (a pair in the Wehrli collection) from Palermo. — fumosata Trti. (Vol. 4, p. 157). fumosata. 
from Frenda, Oran, is evidently, as already suggested, an exceptionally dark form of datinaria; Turati em¬ 
phasizes the characteristic proximal-subterminal spots of the forew'ing. — pallidata Stgr. (7f). We give a pallidata. 
figure of this variable form from Cyprus, where (as well as in Palestine and Syria) it seems to be common in 
the winter months; it is doubtful whether it differs from datinaria in any very stable characters, though it 
is generally smaller, the postmedian line on the whole more sinuous, but too variable in all the races to be of 
much critical value. The pale distal area and the formation and filling-in of the subterminal line in any case 
agree; $ generally paler than the $. The larva, according to Mr. E. P. Wiltshire, is very variable and pro¬ 
duces some forms that are not known in that of our British clavaria ; it is full-fed about March, the greater 
part of the year being passed in the pupal state. His detailed notes are not yet published. Possibly the datinaria- 
pallidata group constitutes a separate species, but the genitalia show too little deviation to warrant that 
treatment. My Palestine specimens were collected in January, one (taken among mallow) being very dark, 
perhaps corresponding to the ab. (?) fumosata of datinaria, but unfortunately not quite fresh. — saisanica saisanica. 
subsp. nov. (7 d). I had seen no material from Central Asia, which Staudinger treated as supplying further 
localities for his pallidata (Saisan and Fergana), until Dr. Wehrli kindly lent, me a U from Saisan, calling my 
attention to the fact that it bore no really close resemblance to the forms from Western Asia. It is evidently 
a good local race, if not a species, although probably nearer to pallidata than to clavaria. Brighter ochre-
