character, and several axillary (anal) veins, starting separately 
from the basal notch. This form does not show the oblique 
cross-veins, but they are obvious in many crickets, at least on 
the dorsal part of the wing. In the form figured ( Eneoptera 
surinamensis) the venation is richer than in Protocoleus, but the

plemented by his restoration (fig. 3, p. 432); 2, Gryllacris (Orthoptera, 
Gryllacrididae); fore wing; 3, Eneoptera surinamensis (Orthoptera, Gryllidae); 
portion of inner margin of fore wing; 4, Venation of Coleopterous elytron, 
synthesized mainly from venation of Cupes and tracheation of Tenebrio. 
general character is plainly the same. In other forms (Gryllinae 
etc.) the veins are even more regular than in Protocoleus. The 
other characters are common to the Gryllacrididae and Proto- 
coleus, though the whole is distorted to form a functional elytron 
and the breadth of the veinless margin is exaggerated. Even in 
the wing as preserved there is a well- veined precostal region,
