insect) by the yellowish sand-grey colour, weakly tinged with reddish. Larva in April on Ochradenus bacca- 
tus, green, with the incisions reddish, the last two segments with broad white lateral stripe. Egypt. 
Ch. pulmentaria palaestinensis Fuchs. Dr. Wehrli, in his valuable working-out of the Geometridae of palaesti- 
Marasch, considers this to be the 2nd and 3rd generation in the East and explains Pungeler’s reference of the 
types to faustinata by the existence of some aberrations which have the white lines bordered with darkened green. 
Ch. faustinata Mill. (Vol. 4, p. 25, pi. 2e). A further synonym is rhoisaria Chret. (Vol. 4, p. 414), to faustinata. 
which therefore belongs the biological detail which we have given under the latter name. The correction was 
made by the author himself in his collection and communicated to me by my kind correspondent M. Lhomme. 
Chretien’s full account of his supposed new species is found in “Le Naturaliste”, Vol. 31, p. 30. 
Ch. (?) sachalinensis Matsumura, the type of a supposed new genus Aoshakuna, is entirely unknown sachalinen- 
to me but may well be a Chlorissa, possibly however a small Gelasma, the g being unknown. Resembles Hem. SIS4 
aestivaria (Vol. 4, pi. 2 d) but not crested, the angle of the hindwing very weak. Olive-green (but probably 
faded), antemedian line indistinct, wavy, postmedian of both wings distinct, excurved in middle; fringe 
whitish. Face brown. 3rd joint of palpus not elongated. S. Saghalien, 1 $, 30 July 1924. 
Ch. anadema Prout (3a). Described as Hemithea; close to the following, but with the crown of the head anadema. 
purple, not white, the antennal shaft also dull purple, the hindwing scarcely angled. Hindtibial process well 
developed, tarsus short. The white lines are very slender. Takao San, 1 <$. 
Ch. tyro sp. n. (= marina part. Prout, nec Btlr., ussuriaria part., nec Brem.) (3 a). In endeavouring tyro. 
to match the faded Hemithea marina (see above) with fresh specimens, I fell into error; tyro is not even 
a Hemithea as now defined, but a near relative of amphitritaria (Vol. 4, p. 25, pi. 2 e). Smaller, wings more 
opaque, deeper green, the white lines more sinuous, conspicuously edged in the median area with brownish 
olive. W. China to Manchuria and Japan; type from Omei-shan in the British Museum. 
Ch. pretiosaria Stgr. (3 a). I have now seen a specimen from the type locality, Transcaucasia (Helenen- pretiosaria. 
dorf), and find sufficient differences in the genitalia to believe it is a different species from the Indian gelida, 
or at the least a different race. Wings a little broader, scarcely so blue, otherwise extremely similar; antemedian 
line of forewing very slight or —• as in Staudinger's type —- wanting. — gigantaria Stgr., from Transalai, may gigantaria. 
belong with this, as described, or (perhaps more probably) with the following. “Considerably larger” than 
pretiosaria, with a “complete, rather broad, segment-formed excurved” antemedian line, 
colour less sap-green, more bluish. I suspect that the blue-green specimens from Margelan, referred (on account 
of their size) to pretiosaria really belong here or to gelida. 
Ch. gelida Btlr. (= anomala Warr.) (3 b). In place of the reproduction of the badly-colonred type figure, gelida. 
given in Vol. 4 (pi. 2 c, pretiosaria), we figure a good $ from Srinagar, Kashmir. The line of the hindwing is 
generally, though not always, well proximal at the costa to the posterior end of the corresponding line of the 
forewing. Fairly common in the Punjab and Kashmir, described from Dharmsala. — exsoluta form. nov. is a exsoluta. 
giant form (38—39 mm) or closely related species from Kulu, the type locality of anomala Warr., with the line 
of the hindwing forming an exact continuation of the postmedian of the forewing. In both the known examples, 
the antemendian of the forewing is obsolescent. Until I can compare gigantaria Stgr., I cannot say positively 
that it may not sink thereto. 
Ck. amphitritaria Oberth. (Vol. 4, pi. 2 e) connects tyro with the Indian nigropunctata Warr. (Vol. 12, 
p. 16). The Nikko “ nigropunctata” mentioned in Vol. 4 and a few other specimens from Japan which I have 
since seen seem to be really an aberrant form of amphitritaria with blacker cell-dots; the process of the 8th 
sternite of the E is considerably shorter than in nigropunctata. C. confusaria Stgr. (Vol. 4, p. 23), if not a syno¬ 
nym, must be a very close ally. 
Ch. distinctaria Walk. (Vol. 4, pi. 2d). Opaquer green than amphitritaria, the dorsal spots or crests 
more blackish, the postmedian line less sinuous, etc. Chiefly X. Indian, but occurs also in W. China.

M . herbaria Hbn. ab. monotona Reisser lacks both the white lines. —- virideciliata Bubacek, from Cor- monotona. 
sica (Calacuccia), is rather larger and deeper green, the fringe entirely green, not (as in herbaria) tipped with vi rmecilia r- 
white. As the apices are somewhat more rounded, it is possibly a distinct species. Typical herbaria also occurs 
in parts of Corsica. 
M. stenopteraria Turati, recently described from Barce, Cyrenaica (as Eucrostis), may — to judge from stenoptera- 
the figure and description — be a large, very feebly marked halimaria or herbaria- $, or their Aethiopian ria ‘ 
representative ruficornis Warr. (Vol. 16, pi. 4d). Palpus, antenna and legs reddish. Forewing acute at apex, 
somewhat as in Eucr. simonyi. Greenish (the unique type somewhat faded), mixed with whitish scales; a 
faint wavy postmedian line visible, on hindwing parallel with termen; costa of forewing slightly ochreous.
