Order — Lepidoptera 



( ^iiAiiACTERisED by the flat coloured scales clothing the four mem- 

 branous wings, the peculiar type of neuration, and the tubular 

 tongue-like structure of the maxillae. A very few Trickoptera 

 show similar scales, but can be distinguished by neuration and 

 mouth parts. The order is divided into nine main groups, 

 which may be tabulated as follows : — 



1. Cell of hindwings emitting more than 6 veins 



9. Micropterygina, 

 „ » not emitting more than G veins 2. 



2. Hindwings with lc absent . . .3. 



„ „ lc present . . .8. 



3. Antennae terminally clavate (clubbed) 4. Papilionina. 



,, not terminally clavate . . 4. 



4. Neuration much degraded . 8. Tineina (part). 



,, not much degraded . . .5. 



5. Hindwings with lb rather strongly furcate 



7. 7'or/riciiKi (part). 

 „ ,, lb indistinctly or not furcate . 6. 



6. Forewings with 5 basally approximated to 4 . 7. 



,. „ 5 parallel to 4, or approximated 



to 6 . 2. Notodontina. 



7. Frenulum present ; 8 of hindwings remote from 7 



1 . Garadrinina. 

 „ absent: or 8 of hindwings approximated 



to 7 beyond cell . 3. lasiocampina. 



8. Middle-spurs of posterior tibiae very short or absent 



(i. PsycMna (part). 

 ,, (or at least one) well-developed . 9. 



9. Wings divided terminally into segments 



5. 1'yralidina (part). 

 ,, not divided into segments . . 10.
