more apical; the fifth by a single oblique spot, divided by two 

 nervures. The apical third of the wing is obliterated, except in the 

 costal region. Sc^ ending 18 mm. from base of wing; r-m cross-vein 

 13 mm. from base of wing; lower end of oblique m-cu. cross-vein 

 9 mm. from base of wing. Longitudinal veins very strong, cross- 

 veins for the most part very faint. The cross-veins from costa to 

 subcosta are more numerous than in Panorpa.

HOMOPTERA. 

 Family DELPHACTDAE. 



AMAGUA, new genus. 



Relatively large robust insects, the anterior wings or elytra rather 

 narrow, parallel sided (apical part lost), with distinct veins; m-cu. 

 cross vein long, branching of cu^ only a little beyond it; anal oblique, 

 not in line with long axis of wing. The general structure of the 

 elytron is not very diiferent from that of Stenocranus saccharlvonts 

 Westwood, but there are numerous differences of detail. The Steno- 

 cranus is relatively minute. 



Genotyye. — A magna fortis^ neAv species.

Plate 1, fig. 2. 



Probable length about 17 mm.; abdomen dark brown, 5 mm 

 broad; elytra (tegmina) 3.7 mm. broad in middle; venation as 

 shown in figure.
