(lnni|) KRIONOTAEIA. 



This group — which was jjroposcd (mttcii. \). 3(').S) to include those genera whose species 

 possessed posterior wings more or less rouvex and about as broad as long — is probably 

 distributed wherever the family is tdimd. 



As already stated, this division is only i)roposed as a ready means of discrimination iu the 

 study of this fauna. I have not presumed to advocate it as of universal application, and iu 

 the words of Captain Cook, I do not wish, in this resi)ect, " to go beyond soundings."

SYNOPSIS OF GENEEA. 



A. Outer and inner margins of anterior wings sul)e(iual in length. 

 ((. Upper and lower disco-cellular ncrvules of anterior wings 



almost subequal in length. 

 /(. Anterior wings elongated, al)Out twice as long as broad, 

 c. Base of second median nervnie of anterior wings about 

 twice as far apart from that of lower as from that of 

 upper median neivule.
