52 NUDARIA; COMACLA; SICCIA. By Dr. A. Seitz. 



4. Genus: Bfudaria Haw. 



Tliis gonus, which only contains ono spocifs, differs from all the allied groups hy i\w broad, very 

 delicate and almost glassy wings, on which thti markings aro onlj- seen as very pale, shadowy lines and 

 spots. Head and bod\' almost naked, only on the frons a very thin tuft of liair. Palpi short. Antennae 

 enveloped at the base by a thick tuft of hair, so that they look incrassate. liody delicate, legs strong, 

 with long, stout coxae, short femora, thin tibiae and long tarsi. Instead of scales, the wings are thirdv 

 covered with fine hairs; they are broad with the outer margin rounded. Larvae fairly plump, with small 

 head, rather transparent skin and stiff hairs, not very dense but partially very long. They inhabit mount- 

 ainous districts, especially frequenting overhanging rocks with lichen, and there one often finds large 

 numbers of them together. In July they pupate in a loose oval cocoon, the pupa being thin-skinned and 

 the moth already appearing after a few days. The moths rest, often gregariously, under slabs of rock, 

 with the wings folded in roof-shape. One can also obtain them by beating the branches of firs. They 

 then fly away slowly and steadily; yet their flight is more easy and adroit than one would except in 

 moths with such delicate wings. 



mundana. N. mundana L. (= transparens Betz., nuda Hhn., hemerol)ia Hbn.) (11 b). Body and- wings dull 



smoky brown, wings semidiaphanous. Forewing with dark dot at the base, and two dark dentate lines 

 before and beyond the centre, between which there is a dark central spot in the cell. In North and 

 Central Europe, from Scandinavia and Finland to the I\Iediterranean, and from France to Anterior Asia, 

 but scattered and generally only in hilly regions. Especially transparent specimens, which occur every- 

 dilucida. where together with true mundana, are called ah. dilucida Fipid. — Egg yellow; larva transparent glossy 

 lead-grey or greenish, with fine hairs, wliich are longer and arranged in tufts anteriorly and posteriorly: 

 the head black. Dorsally there are light spots, before and below which stand black markings. Until 

 June on lichens on stones and walls. Pupa transparent greenish white, later yellowish, with deep black 

 eyes and small minute dark dots on the back, in a loose cocoon which is protected by the hairs woven 

 into it and is attached under rocks and flat stones. One often finds large numbers of these cocoons 

 together. The moths appear in July and August, and settk in the same spots as the larvae and pupae. 

 They are usually very abundant, wherever they occur, and I sometimes found moths, pupae and full- 

 grown larvae together at the same time under the same slab of rock. The moths on the wings strongly 

 resemble Neuropterids of the Chrysopid genus Hemerohius 



5. Genus: Coiuacla ^Yalk. 



Head broad but low, frons flat; eyes small, far apart, the frons being broad; tongue narrow and 

 delicate; palpi pointed, porrect, with long end-segment; antenna of ^ ciliate. Thorax slightly longer than 

 in Nudaria, abdomen stouter, somewhat more densely covered w-ith lough hairs, in the 9 woolly at the 

 apex. Forewings curved downwards in the apical portion, so that the apex is rather pendant, broad, the 

 apex itself rounded. Hindwing broad and long, the anal angle projecting beyond the abdomen. All wings 

 dull light brown, slightly transparent, but considerably more densely scaled than in Niidaria. Larva stout, 

 slightly more denselj' hairy, on lichens; the moth at damp spots where lichens grow. Three species belong 

 here: one from Europe, a similar one from the Gaboon, and a unicolorous one from North America. 



senex. C. senex Hbn. (= rotunda Haw.) (11 b). Not unlike Nud. mundana; the central sjtot at the ii,\wx 



of the coll distinct; a larger shadowy spot at the middle of tlu^ costa, and before the marginal area of the 

 forewing a row of spots which are especially distinct in the costal region. Another curved row of spots 

 bounds the basal third of the forewing. Sporadically in North and Central Europe, southward to the 

 Alps and eastward to the Ural. — Egg round, yellow, larva ashy grey, very hairy, with black head. From 

 the autumn to June on Jungermanniaceae. Pupa stumpy, dark brown, in a dense hair}- cocoon. The 

 moths fly in July on damp meadows, and are not rare in their flight-places; they come to the light at 

 night (Spxilek). 



6. Genus: Siccia Walk. 



Head very broad, eyes small and widely separated by the immense flat frons. Palpi upturned, not 

 projecting beyond the vertex, or obliquely porrect. Tongue strongly developed. Thorax broad with 

 slightly convex back, in the $ the tegulae far apart. Forewing long and much narrower than in the 

 preceding genera, sometimes rather pointed, but the apex not bent down; hindwing more elongate. Ab- 

 domen of the (J moderately slender, that of the $ ending in a thick club, which is covered with wool. 

 Hindlegs long, tibiae not incrassate. Hampson unites here about 20 species, which were formerly placed 

 in different genera; they almost all occur in India and China, only 2 species inhabiting Africa.
