tenth radial nervure always, ninth usually, with trian- 

 gular field. 



Eudermaptera : veins of squama with cross-connection : 

 third vein with sector ; ulnar vein without inner 

 branch; triangular field to ninth radial nervure ; the 

 tenth 4-shaped. 



We may now proceed to a consideration of the wings of a 

 few species, and then see to what extent these observations 

 affect Zacher's expressions. 



Protodeumaptera. 

 Kalocrania picta, Guer. (PI. III. fig. 1.) 



The wing is extremely delicate ; my specimen being un- 

 stained, the smaller nervures are very obscure, the whole 

 wing being remarkably transparent and ghost- like. 



Both squama and ulnar area are strongly broadened 

 apicad and narrow basad. Veins of squama with uo cross- 

 communication. 



Third veiu with no sector. 



The inner branch of the ulnar vein is very strong, more 

 prominent indeed than the ulnar vein itself; soon after its 

 origin it throws off a short, straight subsidiary branch at 

 right angles, and then fuses with the ulnar veiu at the origin 

 of the tenth radial nervure, then branching off again to the 

 base of the wing. 



Ninth radial nervure straight. 



Tenth Y-shaped. 



Eleventh looped. 



No pubescence. 



The first and second nervures are joined at the base. 



Allosthetella malayana, Zacher. (PI. III. fig, 2.) 



The wiug is rather long and narrow. Zacher states that 

 the first vein of the squama is strong and hairy, the other 

 two very faint. As I read my specimen, the first is hairy, 

 the first and third faint, and the second strong. Contrary 

 to what Zacher says, the inner branch of the ulnar vein does 

 actually reach, though very indistinctly, the third vein of 

 the squama and so is confused with the sector. The apex of 

 the ulnar area, as well as the triangular field of the tenth 

 nervure, are hairy ; the first and second nervures are joined 

 at the base. 



The ninth nervure is straight, the tenth Y-shaped, and 

 eleventh looped.
