from Ophion. From the latter it is at once known by the 

 very strongly bisinuate base of the radius, elongately antefuroal 

 nervulus and nervellus, the traces of areae on the mesopleunu, 

 apically bro;idly subexcava^e metanotum, which is transversely 

 strigose ; the mesosternum is granulosely punctate, apically 

 immarginate, with a fovea below the punctate speculum.

c? $ . A large testaceous species, with only marks at base 

 of front wings behind tegulse black, and in $ the third segment, 



with anus, indeterminately

 Wings with a distinct gla-

Type in the Oxford Museum. 



This species is very like A. undulalus, Grav., but is larger and 

 paler, with the antennae and two basal segments longer and 

 distinctly more slender, the stigma narrower and nearly always 

 darker, emitting the radius more obliquely and less directly ; the 

 internal cubital nervure is geniculate a* little before and not 

 distinctly beyond its centre, as in the latter species, which has its
