100 LEPIDOPTERA HETEROCERA 
angle, 4 absent, 7 absent, 8 and 9 stalked, 11 from beyond middle. Hindwings 1/2, very narrowly 
elongate-trapezoidal, acutely pointed, cilia 4; 2-4 parallel, 5 approximated, 6 and 7 long-stalked. 
Remarks. — A development of TAiotricha. The species are very similar, but good distinguishing 
characters are found in the secondary sexual structures of the male palpi and antennae. In repose the 
posterior legs are thrust forwards beneath the wings and erected on each side of the shoulders. "This 
singular habit at once suggests Sfa/hmofoda (Heliodinidae), to which there is also an extraordinary resem- 
blance, not only in superficial appearance but in many details of structure, and hence Stainton was led 
to place the European Guerini actually in Stathmofoda (where it still remains in Staudinger's Catalogue), 
though he correctly noted and emphasized the different form of hindwings, but without recognising 
their Gelechiad type. No adequate explanation of these curious analogies in abnormal characters can 
be given, but it is possible that local research in India would show that there is a third (non-Lepidopte- 
rous) group of insects, of which both these genera are mimics. 
Geographical distribution of species. — Indo-Malayan, with one species on the Mediter- 
ranean. 
Larva (2 known) feeding in Aphid-galls on leaves.

103. GENUS HIERANGELA, MEYRICK 
Hierangela, Meyrick, Trans. Ent. Soc. Lond. p. 14 (1894). — Type : H. erythrogramma, Meyrick. 
Characters. — Head smooth; ocelli posterior; tongue developed. Antennae 5/6, in cy serrulate, 
simple, basal joint slender, without pecten. Labial palpi very long, recurved, smooth, slender, second 
joint somewhat thickened, terminal joint longer than second, acute. Maxillary palpi rudimentary. 
Posterior tibiae clothed with hairs. Forewings with 1? furcate, 2 from towards angle, 7 absent, 8 and 9 
stalked, 1o approximated, rr from beyond middle. Hindwings under :r, narrow-trapezoidal, apex 
strongly produced, acute, termen emarginate, cilia 3; 3 and 4 connate, 5 rather approximated, 6 and 7 
connate. 
Remarks. — Correlated with T/iotricha. An elegant insect, with crimson and yellow colouring. 
Geographical distribution of species. — Indo-Malayan. 
Larva unknown.
