The Cardbid genus Pher&psophus. 201 



to P. cinctus, Gory, by Chaudoir, but it seems very unlikely 

 that trie insect can range from Senegal to the Upper 

 Congo. The species called tenuicostis by Chaudoir will 

 require a new name, for I cannot regard that used as 

 admissible, P. tenuicostis, Laferte, being by his showing 

 synonymous with P. cinches, Gory. I propose for it the 

 name lafertei. 



I have seen two specimens of P. marginipennis, Lap., 

 which Chaudoir suggested might be a variety of P. 

 parcdlelus. It is a quite distinct species with no trace of 

 median ornament. The elytra are rather shorter, with 

 less elevated costae, and the apical border is sinuated and 

 rather vaguely limited. 



P. tristis, sp. n. 



Kufo-testaceus, verticis puncto, prothoracis marginibus antica et 

 postica lineaque media nonnunquam interrupta nigris, lateribus 

 antice valde arcuate ampliatis, postice contractis, angulis posticis 

 rectis ; elytris longis, angustis, obscure nigris, marginibus laterali et 

 apicali tenuissime (rarius epipleuris totis suffusis) flavis, humeris 

 prominentibus, lateribus parallelis, costis latis, parum elevatis ; corpore 

 subtus pedibusque testaceis, epimeris plus minusve abdomineque toto 

 infuscatis. Long. 16 m.m.

Also belonging to Chaudoir's " africanus " section, this 

 species is perhaps most allied to P. palmarum, Chaud., of 

 which there are examples in our collection from the same 

 locality. The head and thorax are almost the same as in 

 that species, but the elytra are rather longer and less shin- 

 ing, the costae being flatter and broader. The shoulders 

 are more prominent and the sides of the elytra more paral- 

 lel. The extreme margins alone are yellow, this colour 

 being sometimes hardly traceable at the sides and some- 

 times covering the whole of the epipleurae. 



I have examined four specimens, of which two are in 

 the British Museum and two in Dr. E. A. Heath's 

 collection. 



P. arabicus, sp. n. 

 Parvus, angustus, testaceus, abdomine elytrisque nigris ; capite 

 immaculato, prothoracis marginibus antica et postica nigris, lateribus 

 valde bisinuatis, disco medio profunde sulcato ; elytris tenuiter costa- 

 tis, lateribus parallelis, humeris evidentibus, singulo elytro macula 

 magna subrotundata flava ornato, margine apicali flava, intus hand
