stricted at the middle. On felled timber, under bark, and 
flying, usually at a considerable elevation (Walker).

The known species of this genus are all from New 
Zealand. Mr. Walker obtained single specimens of two 
species in Tasmania; one of these has, unfortunately, 
been lost ; the other is described below. 
Techmessa ruficollis, n. sp. 
Moderately elongate, narrow, the head opaque, the prothorax 
and elytra slightly shining ; black, the prothorax rufo-testaceous, 
the oral organs obscure testaceous, the antennae and legs black, 
the knees and tarsi paler ; the upper surface sparsely clothed with 
long, fine, cinereous hairs, many of which are erect. Head densely, 
rugosely punctured ; the eyes prominent, rounded, entire, and 
finely granulated ; antennae rather short, not half the length of the 
body, moderately slender, joint 1 stout, 2 short, 3 twice as long as 
2, 3-10 subequal, 11 ovate, slightly longer than 10. Prothorax 
strongly transverse, convex, about as wide as the head, coarsely, 
closely punctate, the disc very deeply foveate on either side about 
the middle. Elytra about five times the length, and nearly twice 
the width, of the prothorax ; very coarsely, deeply, and closely 
punctate, the punctures much coarser than on the prothorax. 
Length 4|, breadth 1^ mm.

The single specimen described has the thorax abnor- 
mally formed, it being rounded on one side, and sub- 
angularly dilated on the other; the latter is perhaps the 
normal shape. As the genus is an addition to the 
Australian fauna, I have ventured to name the insect. 
T. ruficollis somewhat resembles the figure of Megalocera 
rubricolUsj Hope (Mag. Zool., 1842, t. 88). Under Euca- 
lyptus bark (Walker).
