Family ii. — Lagoid.e. 



We have already attempted to show that Lagoa is the type of 

 a distinct family, intermediate between the Cochliopodida; and the 

 Ijparidae. (Psyche, July, 1892. p. 281). 



Family 12. — T,ii>AKii).t:. 



Of this group Carania and Arfaxa may be the more generalized 

 forms, Dasxchira, Laria, Parorgyia follow, the most modified and 

 recent form being Orgyia, with its wingless females.* 



Family 13. — ARcniD.ii. 



The most generalized form appears to be Halesidota, with its 

 tufted larva. The IJthosiidie are certainly very difficult to separate 

 from the Arctians, and after careful consideration of the head and 

 wing characters, I do not feel sure that they should be treated as 

 a separate family, but rather as a sub-family. The chief distinction 

 is in the antennae, those of the Lithosiidse being simple. Whether 

 Nola should be regarded as the type of a distinct family, or as 

 a sub-family of Lithosiids is a matter for debate. Butler places 

 Lycomorpha in the Fithosiidce, but I regard it as a Zyg^nid. 



Family 14. — Zyc/ENID,?:. 



The next great group is the Zygifoiii/a'. Whether it should be 

 regarded as equivalent to the Bombyces as a whole, may well be a 

 matter of doubt. Since some of the simpler forms intergrade with 

 the Lithosians, I am inclined to think that the group is simply a 

 family, and that it should perhaps be associated with the Lithosians 

 and Arctians under the Bombyces, since the larvas are spinners 

 and hairy, with tufts or pencils of hairs. 



At present T think the Zygxnidre should be divided into three 

 sub-families, i. and lowest^or most generalized, the Syufo»ici/i(T 

 (Glaucopinae); 2. the Zyi^(r/i7^; ami 3. llic Dioptin.v, our North 

 American form being Phryganidia. 



The Zygcenidne as thus circumscribed, are very distinct from 

 the* next family, and I am inclined after recent • studies on the 



* I have satisfied myself by a study of the venation, etc., that Varina ornata 

 Neum. referred to this family in Smith's List, is a Noctuid. Prof. Smith has dis- 

 covered that it is a synonym oi Acherdoa ferraria Wallv. (See Can. Ent. xxiv. 

 June 1892, p. 135.) Prof. Smith, however, appears not to question its position 

 among the Bombyces.
