O94 STAPH YLINIDA. 
punctured. Thorax about as broad as long, much narrowed behind and in front, convex, 
subglobose, very densely sculptured, almost unimpressed. Elytra broad, much wider 
and rather longer than the thorax, very densely sculptured. Hind body rather broad, 
the penultimate segment not tubular. 
One example, in very decayed condition. 
In this distinct species the labrum has a median angular notch, and a smaller notch 
on each side. 
7. Echiaster curtus. 
Brevior, ferrugineus, elytris dimidio apicali nigro ; capite suboblongo, prothorace latiusculo, bisulcato. 
Long. 3 millim. 
Hab. Guatemaa, El Reposo (Champion). 
This insect seems to occupy an intermediate position between the true species of 
Echiaster, which have one or two of the terminal segments more or less tubular in 
structure, and the following one, in which this part of the body is of the form usual 
in the subfamily: in £. curtus the terminal segments are rather broad, and not elongate, 
but their sculpture and clothing are similar to that existing in the species where the form 
of these segments is more elongate; also, as in these latter, the penultimate segment is 
only finely margined, and the terminal one is not margined. In £. curtus the head is 
suboblong in form, almost subquadrate, and the moderately small eyes are placed far 
from the front. The thorax is about as long as broad, much narrower than the elytra, 
much narrowed behind, and with two longitudinal depressions, separated by a broad and 
feeble elevation. The elytra are broad and short, a little longer than the thorax. The 
sculpture throughout is very fine and indistinct, the surface quite dull, the two terminal 
segments clothed with dark hairs. The labrum is acutely quadri-denticulate, the two 
lateral teeth much shorter than the median pair. 
The unique example is in bad preservation. 
8. Echiaster lativentris. (Tab. XV. fig. 15.) 
Nigricans, confertissime punctatus, opacus ; prothorace vel rufescente vel nigro; elytris disco late angulariter 
rufo-signato ; abdomine lato, apice obtuso, segmentis basalibus parce flavo-setulosis ; antennis pedibusque 
rufis. 
Long. 33 millim. 
Hab. Guatema.a, Capetillo, Las Mercedes, Cerro Zunil, El Reposo (Champion). 
Antenne short, not much thickened externally; penultimate joint not transverse, 
those preceding it shorter, transverse. Head suborbiculate, the eyes rather large and 
convex. Thorax moderately narrow, longer than broad, much narrowed behind, longi- 
tudinally elevated along the middle, and sulcate on each side, very dark red, or black. 
Elytra short and broad, scarcely longer than the thorax; with a large subtriangular 
rufescent mark on the disc, the base of the triangle extending across the elytra and
