greenish line being iridescent or a mere surface-tint; the extreme apex is brownish, 
but before this tint it is black, as well as the suture in its whole length. ‘The legs are 
dark externally, greenish internally. 
Two specimens only of this have been sent, among Mr. Champion’s latest captures on

A genus remarkable for the closeness with which its species mimic small Lycide and 
Lampyride. It is found all over the warmer parts of both the northern and southern 
continents of America, being represented in the United States by one species, J. lati- 
cornis, Say. The species are generally rare in collections, but probably only require 
looking for carefully in their haunts, since a very considerable number of some were 
found by Mr. Champion. About twenty-four species are now described, chiefly from 
South America. A memoir on the genus will be found in the Trans. Ent. Soc. Lond.

1. Ichnea histrica. (Tab. X. fig. 1.) 
Nigra, capite prothoraceque flavis, hoc antice angustato, lateribus sinuatis plagaque mediana nigris; elytris 
postice paullo ampliatis, seriatim punctatis, plaga humerali ultra medium producta ferruginea, limbo 
laterali tenuiter, sutura trienteque apicali oblique nigris. Long. 8-9 millim. 
Hab. Panama, Bugaba (Champion), 
Allied to I. lycoides, but with the thorax less suddenly bowed behind at the sides, 
yet constricted in front, where it is narrower than at the base. The sides are impressed ; 
and there is a small punctiform impression on the base in front of the scutellum. ‘The 
elytra are evenly punctured in close-set rows; the yellow humeral streak is clothed with 
a fine, silky, shining golden pubescence, which is also visible upon the yellow lines of 
the thorax and on the head behind. ‘The yellow extends further along the margin 
than near the suture; it is divided for a short distance by a black streak from the 
apical portion; the suture is black throughout as far as the second series of punctures. 
The front pair of legs are wholly black; the middle and hind pairs have the femora 
yellow in the basal half. 
This species is not unlike a small L. meaicana, from which its serial punctuation and 
the central black vitta of the thorax distinguish it. It is also not very dissimilar from 
I. funesta, Gorh., to which it is allied both in the form of the thorax and in the black 
vitta. In that species the humerus is cnly adorned with a narrow and short yellow 
striga, and the thoracic vitta is much more attenuated anteriorly. In colour this species
