SPHRAGIDOPHORUS. 63 
base to the apex with scattered setiferous impressions; the legs vary in colour from 
black to testaceous, and the femora and tibie are furnished with a few long hairs; and 
the under surface also varies in colour, though the venter is always more or less black. 
The male exhibits the following characters :—The anterior and intermediate femora 
are deeply sulcate within from the base nearly to the apex; the anterior tibie are a 
little curved inwardly, and broadly concave within, the concavity opaque; and the elytra 
have each at the side a large oblong perfectly opaque black or ashy median patch, upon 
which faint. lines representing the position of the strize are visible. The opaque 
patch at the side of the elytra is also exhibited in the male of the following species 
(and in the female, the only sex known, of S. singularis) and in other Lagriide 
inhabiting Tropical South America; it is absent in the female of S. cyanipennis. The 
cedeagus of the male is developed in an extraordinary manner, and when extruded 
a very long and slender clasping-piece, hooked at the end, is to be seen on either 
side of the central sheath. 
The description of Maklin, though lengthy and based upon male examples, is very 
incomplete, the important structure of the anterior and intermediate legs &c. being 
overlooked altogether. 
Five examples are now before me, including both sexes. 
b. Upper surface unicolorous, violaceous. 
2. Sphragidophorus violaceus. (Tab. III. fig. 18, 3.) 
Rather short, subopaque, violaceous. Head with a few scattered coarse deep setiferous punctures, the eyes 
small and distant from the base; antennez (¢) very long and stout, black, the apical joint not quite so 
long as joints 8-10 united; prothorax about as long as broad, cylindrical, the sides immarginate, mode- 
rately rounded in front, and constricted behind, the hind angles acute, the disc transversely impressed in 
the middle behind, the basal margin moderately raised, the surface with a few widely scattered coarse 
deep punctures between which are some finer ones; elytra (in the male) with a large oblong perfectly 
opaque brownish-black lateral patch about the middle (upon which faint lines indicating the position of 
the strie are visible), comparatively short, widest about the middle, finely punctate-striate, the punctures 
becoming much coarser towards the sides and obliterated before the apex, the interstices flat, rather convex 
towards the apex, the first, third, and fifth each with a few widely scattered fine setiferous punctures, the 
apices obtuse ; beneath violaceous ; legs dark violaceous, the femora and tibize each with a few long scat- 
tered hairs. 
¢. Anterior femora a little curved, very deeply sulcate within from the base to about the middle, dilated on 
the lower side at the extreme base, and with a small deep ovate depression on their upper face at the 
extreme apex ; anterior tibie slightly curved outwardly, and very deeply sulcate on their upper face from 
the base to the apex. 
Length 5 millim.; breadth 13 millim. (¢.) 
Hab. Panama, Bugaba 1000 feet (Champion). 
One male example only. This very interesting little species is allied to, though 
much smaller than, the preceding, and, like it, possesses very peculiar male characters. 
It also differs thus :—The upper surface is uniformly violaceous ; the antenne ( ¢ ) have
