EXPLANATIONS OF PLATES II AND III. 



The accompanying figures of the neuration of Saturniades are obtained by photo- 

 graphic process and may thus be relied upon for exactness. The numbering of the 

 veins is in accordance with the corrected Redtenbacher Comstock system as applied 

 to the Lepidoptera. 111 = Radial veins; lV=r Median veins; V = Cubital veins. 



Fig. I. — Saturnia pavonla malor. This and the succeeding represent the 

 Saturnian type, in which IV2 becomes continuous with IVl. The crossvein ap- 

 pears to obtain merely between IV2 and IV 1 the middle branch of the Media 

 becomes Radial. In the Attacinze, here not represented, the crossvein vanishes. 



Fig. 2. — Hemlleuca mala. — The same Saturnian type is exhibited with the 

 secondary distinctions that vein IIIi-{-2 springs from the Radius above the cell. In 

 Saturnia it has travelled upwards to a point just before apex; by this character 

 Hemlleuca is more generalized. Also with the difference that vein VIII of hind 

 "wings, suppressed in Attacus and Saturnia, is here retained. Else it equals 

 Saturnia. 



Fig. 3. — Aglla tau. This and the succeeding figure repiesent the Aglian type 

 of wing. Attention is called to the oblique outward direction of the still uneven 

 portion of the crossvein between IV2 and IVi, the first indication of a secondary 

 aiovement tending to the disintegration of the system of the Media. 



Fig. 4. — Automerls lo. The crossvein is transverse, and no indication of the 

 secondary movement of the crossvein in Aglla is observed. The point of issue of 

 IIIl-f-2 is removed further towards the base of the wing. In these two points the 

 Automerid wing lags behind, or is more generalized, than the typical Aglian wing. 

 Else it equals Aglia.
