PEOCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING lOOT 



genus Acrocercops, which though cosmopoUtan is at its maximum ia 

 India. 



The Epermeniadce are everywhere a scanty group, represented by 

 a dozen species. The curious Idioglossa has gilt markings on both fore 

 and hindwings, an unexplained eccentricity. The typical forms of 

 Epermenia have scale-teeth on dorsum of forewings. The larvae ar& 

 external feeders on leaves, protectmg themselves by a slight web. 



The AmphitJieridce are another small group of narrow-winged insects, 

 with long antennae, and the eyes usually curiously divided by a line of 

 scales ; I have 6 species. 



The Plutellidce nearly resemble the Hyponmneutidce, from which 

 they are distinguished by the distinct short porrected maxillary palpi. 

 They are an ancient family, not now numerous anywhere, though 

 Plutella maculipenms ^is the most universally distributed of all the- 

 Micwlepidoptera ; there are about 20 species. The known larvae are 

 leaf-feeders. 



The Lyonetiadce are typically rough-headed, with folded maxillary 

 palpi like the Tineidce, but advanced forms have suffered much degrada- 

 tion, and may have lost these Structures ; the distinguishing mark 

 of the family is the upturned (or sometimes down-turned) apex of 

 forewing in repose, sometimes very strongly marked and striking, looking 

 like a deformity, and the basal joint of the antenna often forms an eyecap. 

 I have nearly 100 species. Some of these insects are amongst the smallest 

 and most delicately marked of the Lepidoptera, Such as Phylhcnistis, 

 which is probably rather numerous, requiring close study ; its larvae 

 mine flat blotches ia leaves. Opostega, which is probably also numerous, 

 has the most degraded neuration of all Lepidoptera ; its larvae are 

 scarcely known. The larvae of Bucculatrix, although of very small 

 size, feed externally on leaves, and have a peculiar ribbed cocoon. The 

 earlier genera usually have larvae feeding on dry vegetable matter ; 

 those of Opogona are often resident in the nests of Termites. The family 

 as a whole is very interesting for study. 



The Tineidce are an extensive group, with normally rough head 

 and often folded maxillary palpi, the neuration well-developed and 

 simple, the veins of hindwings usually separate. I have over 200 species, 

 but some genera are very obscure and need much more study to discri- 

 minate the different forms. The species of Melasina are especially 

 difficult, and good series should be taken, but even then two or three 

 species may occur commonly together. The larvae usually feed on 

 dead or dry vegetable (or sometimes excremental) matter, fungi, bark, 

 dead leaves, roots, etc., but in other countries are occasionally leaf-
