This curious insect is named in honour of its discoverer, the 
late Julien Desjardins, whose exertions in the cause of science in 
the distant island of Mauritius merit far greater respect than can 
be shown by this feeble mark of recognition, 
One of my specimens is curiously deformed in one of its 
antennz, as represented in the accompanying sketch, the two 
apical joints being soldered together, and the preceding joint more 
elongated than in the opposite antenna, as though to make up for 
the deficiency in the number of joints. 
* P.S. Ihave added this citation at the suggestion of Mr. A. White. The 
insect described by the Marquis Spinola is however stated to be a native of the 
Cape of Good Hope, and is arranged both by him and by M. Germar (in the 
Rev. Entomol. de Silberman, tom. v. p. 134, No. 34) as one of the Aradites, 
the antennz being described as 4-jointed, the first extremely minute and basal, 
the second small and pear-shaped, the third long and clavate, and the fourth very 
minute and setaceous. Upon this mode of computation the left hand antenna of the 
insect above described by me must be considered as having seven joints. The learned 
Marquis has moreover represented his insect as not possessed of two ocelli, nor as 
having the closed cell at the base of the membranaceous part of the hemelytra. 
The head moreover in my insect does not exhibit the two deep circular impressions 
between the eyes, seen in M, Spinola’s figure of Phricodus hystria,
