Ztg^na mixos (Type) [Plate I., fig. 5 a]— Galway. I captured a 
considerable number of this insect in a pasture near Galway, 
in July, 1860. 
„ NUBiGENA (Variety) [Plate I., fig. 6 b] — Galway and Clare ; 
local, but in profusion wherever found. The differences 
between minos and nubiffena are, I think, sufficient to justify 
the separation which has been made by continental entomolo- 
gists, and may be thus stated : — 
Minos. Nubigena.

Covered with long, shaggy, dead

Costal streak always meets or

of them through the kindness of Professor Wyville Thomson.
