intervals flat, sparsely and finely muricate-punctate, each 
with a row of conical tubercles, which become much larger 
and closer at the sides and apex, each tubercle with a 
rounded puncture at apex ; the sutural and each alternate 
interval more shining than the others : apex of the tibias 
not appearing produced within, their inner edge straight 
throughout, outer edge of the anterior tibia3 feebly spined : 
underside, legs and antenna pitchy-brown, palpi — and 
sometimes the tibife — dull red : flanks of prothorax finely 
reticulately plicate : breasts hairy : antenna3 moderately 
perfoliate, thicker and slightly depressed outwardly ; joints 
8 — 10 rounded ; 11 larger than 10, ovoid.

MiCRECTYCHE, n. g. 
Antennoi short, compact, not perfoliate ; joint 3 ordi- 
narily larger than 4 ; 4 — 7 subequal — or very gradually a 
little shorter and wider — obconic; 8 — 10 stouter, gra- 
dually transverse, subtriangulate ; 11 large, briefly oval, 
or globular : epistomal suture obsolete : i)rotlwrax with a 
more or less distinct flattened margin, usually feebly 
crenulate at the edges ; emargination of the basal angle 
generally very strong, and with a prominent, acute tooth 
in the centre ; or, it may be said, there is a more or less 
deep, rounded excision in front of the hind angle, the 
angle itself being acutely dentiform, and the margin 
behind leading a little sinuously to the base, which is more 
or less broadly rounded : humeral angles of elytra more or 
less strongly dentiform : tibice short, straight (except in 
intermedia), robust ; the anterior triangular, their inner 
edge ordinarily straight throughout, their outer edge 
(except in intermedia) unspined, their a})ex not obliquely 
truncated, but produced outwardly into a strong, bifid 
tooth: jirosternum not abruptly elevated; mesosternum 
strongly declivous in front. Species of small size, rather 
robust, pilose. 
Very near Ectyche, but distinct by the characters 
indicated, and by the form of the antennce especially. It 
is probable the Ectyche^. nana, Pascoe, may belong to 
this genus. 
As i-egards the three species, and one sup])oscd variety, 
of this genus, described below, they are sufficiently close
