T. uhni. — Elytra pale, with brocaded tips. Abdomen

T. Douglasi. — Elytra with pale orange-clouded mem- 

 branes. Abdomen brownish, with golden edges. In- 

 sect is rather larger than T. aurovittata. 



T. gratiosa. — Elytra almost white, with fumose tips. 



T. cratcegi. — Very like the former, but smaller. 



T. tenerrima. — Elytra very similar to T. uhni. 



The following species cannot be separated by the 

 eye, unassisted by a lens ; they are all in colour 

 yellowish : — Typhlocyha rosce, T. Lethiernji, T. avellana, 

 T. hippocastani, T. saUcicola, T. opaca, and T. pruni. 



Genus XLIX.— ZYGINA,* Fieh. 



Elytron long and without a limbus. Three longi- 

 tudinal nervures nearly parallel and terminated by 

 short transverse nervures ; from the angles of which 

 short nervures proceed to the apex, and mark out 

 the tips into oblong unequal areolets. The first 

 and second wing-veins unite before passing, as one, to 

 the margin. The third vein simple, but united to the 

 second by a short nervure (omitted in the figure). The 

 elytra and wings often are too delicate to show the 

 neuration.
