The accompanying hgures 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. Him Radial veins j IV Median veins 5 V m Cubital veins. 
Fig* I. Saturnia pavonia maior. This and the succeeding represent the 
Saturnian type, in which IV2 becomes continuous with IVi. The crossvein ap¬ 
pears to obtain merely between IV2 and IVi the middle branch of the Media 
becomes Radial. In the Attacinae, here not represented, the crossvein vanishes. 
Fig* 2.— Hemileuca maia. —The same Saturnian type is exhibited with the 
secondary distinctions that vein IHi-f 2 springs from the Radius above the cell. In 
Saturnia it has travelled upwards to a point just before apex; by this character 
Hemileuca 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 -— Aglia tau. This and the succeeding figure represent 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 
movement tending to the disintegration of the system of the Media. 
Fig. 4 *— Automeris io. The crossvein is transverse, and no indication of the 
secondary movement of the crossvein in Aglia is observed. The point of issue of 
II 1 1H - 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.
