Hemileuca maia.—A_ generalised wing with the veins curving, tending to 
separate unequally, vein VIII of secondaries retained, traces of base of 
media and vein VI. Veins IV 1 and IV 2 ona stem, which latter belongs 
morphologically to the cross-vein. The two upper branches of the media 
furcate, approaching at base; the portion of cross-vein between them is 
still angulate, and reveals its origin. For an instance of the complete 
vanishment of this angulate piece see figure of Attacus (ante, p.47). This 
wing is then more generalised than that of Automeris, but the disintegration 
of the median system has proceeded upon a different plan. Vein IV 2 
has left its central, generalised position, and is drawn to radius. The 
cross-vein between IV 2 and IV 3 has lengthened; the whole cell is 
differently shaped and formed from that of the Aglian type. Compare 
with Fig. 4, Saturnia pavonia-major, and contrast with Fig. 1, Automeris io.
