one very long ; surface punctured, ashy, the sides occupied by a 
dark-brown streak or elongate patch, of very irregular outline 
and broken throughout with short spots and lines of the ashy 
ground-colour of the elytra. Body beneath clothed with ashy 
pile. Legs reddish ; hind tibise with rather long apical spurs.

Genus Baryssinus, nov. gen. 
Body oblong, convex. Antennse stout, furnished sparingly 
with setae beneath. Thorax somewhat short and broad, widening 
from the front to the tips of the lateral spines, which are very 
thick, and placed near to the hind angles. Elytra furnished with 
centro-basal tubercles, surmounted each by a pencil of hairs; the 
rest of their surface naked ; apices scarcely perceptibly truncated. 
Apical abdominal segments in the male short and obtuse, in the 
female slightly prolonged, so as to form a short sheath for the 
ovipositor, the dorsal plate being flattened and obtuse, the ven- 
tral bluntly truncated. Mesosternum depressed, not tubercu- 
lated. Legs stout; thighs clavate; basal joint of the tarsi 
short, not surpassing in length the second and third taken 
together. 
' This genus, which comprises a few small species resembling 
Trypanidius in facies, has some affinity with Leptostylus. We 
are therefore, after pursuing the line of affinities which leads 
through a series of depressed forms of Leiopodinse from Alcidion 
to Parcecus, brought back again to the starting-point, — the pre- 
sent genus commencing a suite of genera of more convex form 
of body. The presence of hairy-crested centro-basal ridges or 
tubercles distinguishes Baryssinus from all the genera which 
follow, whilst the existence of a prominent ovipositor in the 
females, and the shape of the thorax, with the position of its 
lateral spines, separate it from Leptostylus and the allied groups. 
1. Baryssinus penicillatus j n. sp. 
B. oblongus, cinereo-brunneus, fusco obscure variegatus : thoracis 
dorso antice tumido : elytris utrinque tricostatis, apice rotundatis. 
Long. 4 lin. S . 
Head ash-coloured. Antennse stout, one and a half times the 
length of the body ( cJ ), stout, setose beneath, ashy testaceous, 
tips of the joints (from the third) dusky. Thorax with the an- 
terior part of its disk rising into a large obtusely conical eleva- 
tion ; lateral spines stout and curving posteriorly ; surface ashy 
brown, with indistinct darker brown markings. Elytra oblong- 
quadrate, being but slightly narrowed to the tips, which are 
broadly rounded ; the disk of each has three faintly marked ribs 
which do not reach either the base or the apex; centro-basal
