more inclined to be granulose than in the female specimens which I refer to Telephorus 
picticollis.

The general appearance of this insect is almost exactly that of a species of Cleride ; 
the form, evenly narrowed before and behind, the short serrate antenne, the colour of 
the thorax (black, with an oblique red vitta on each side, which leaves the margins 
black), are all repeated, and are similar to the general features of several species of 
Photinus as well, so that the deception in nature must be perfect. The species appears 
to vary a little in size and in the width and form of the black discoidal patch of the 
thorax. Thus one variety will resemble some one species of Photinus, while another 
may be more close in general facies to another. 
The abdomen has one or two apical segments, and the margin of some of those 
preceding, whitish. ‘The anterior internal claw of the male has a lobe at the base; but 
while the middle pair seem to have the same claw thickened, it is not so widened. The 
hind claw is thickened and finely bifid. 
The figure in the Plate is taken from a female from Duefas. 
14. Discodon photinoides. (Tab. V. fig. 19, Telephorus.) 
Nigro-fuscum ; capite nigro, epistomate flavo ; prothorace flavo, plaga discoidali subtriangulari nigra; elytris 
fuscis, margine laterali et sutura tenuiter flavis. Long. 9-11 millim. ¢ 9. 
Mas prothoracis margine laterali tenuissime plicato-interrupto; unguiculis anticis internis basi lobatis, 
intermediis et posticis externis basi incrassatis haud fissis.

There appear to be several species closely resembling the present one, and whose 
discrimination depends on the observation of differences in the structure of the claws of 
the males. Nevertheless, if these are attended to, there will, I think, be found other 
minute differences in the average size, the more or less parallel form, the shape of the 
thoracic discoidal patch, and the form of the male ventral segments and their colour. 
This species has the extreme front of the head yellow. The thorax is smooth and 
even, with a somewhat triangular patch on the disk. The elytra are rather parallel, a 
little widened in the female, and attenuated towards the apex. The abdomen is wholly 
dark fuscous; in only one example is it at all paler towards the apex.
