LISSORHOPTRUS. 135 
curved ; the third tarsal joint narrow and not wider than the second ; the prosternum 
level. The sculpture of the elytra, too, is peculiar, the interstices towards the sides 
and apex being furnished with scattered, small, rounded tubercles.

Oblong-ovate, faintly shining, black, densely clothed with greyish-ochreous agglutinated scales, the prothorax 
with a rather broad median vitta and the elytra with a broad common discoidal patch extending to 
beyond the middle almost bare, the antenne and tarsi ferruginous. Rostrum very stout, shorter than 
the prothorax, densely, minutely punctate ; antenne short, the club rather narrow. Prothorax transverse, 
subquadrate, strongly and abruptly constricted in front, densely granulate. Elytra fully one-half wider 
‘than the prothorax, subparallel for some distance below the base, flattened on the disc, the basal margin 
raised, and the humeri prominent and obliquely truncated; deeply punctate-striate, the interstices not 
wider than the strive, convex, and rugulose, the alternate ones with a series of small rounded tubercles on 
the apical declivity, each bearing a short, decumbent, pallid seta. Tibi stout, the intermediate pair 
strongly curved; tarsi narrow. Metasternum and first ventral segment with a common depression in the 
middle in the ¢. 
Length 3 millim.

The above description is taken from a clean specimen from Guatemala, North- 
American examples not being available for comparison, and the identification therefore 
is not quite certain.

Oblong-ovate, black, densely clothed with brownish-grey, shining, agglutinated scales, which are slightly 
mottled with paler colour, the antenne and tarsi ferruginous. Rostrum very stout, shorter than the 
prothorax, densely, minutely reticulate. Prothorax transverse, narrowed in front and behind, and slightly 
constricted before the apex ; the surface (when viewed under a strong lens) densely, minutely granulate, 
the granules flattened and larger than those on the head or elytral interstices. Elytra oblong-ovate, flattened 
on the dise anteriorly, much wider than the prothorax, deeply punctate-striate, the strie narrow and 
reticulate, the interstices flattened, the alternate ones on the apical declivity, and the fifth and seventh from 
a little below the base, furnished with small scattered rounded tubercles. Tibiz stout, the tarsi narrow. 
Length 24 millim. 
Hab. Norra America! 2, Southern States and Texas *—Panama, David (Champion). 
The single specimen from the State of Panama described is so like an unnamed 
North-American Bagoid sent me by Mr. Wickham, which appears to be referable to 
L. apiculatus, Lec., that it is inadvisable to separate it, the only appreciable difference 
being the rather more rounded sides to the prothorax in the David insect.
