. and Species of Longicorns. 279 



Blepisanis. 



(Phyta ciinffi.) 



Caput antice convexum, inter oculos sulcatum ; lahrum breve, trans- 

 versum. Oculi profuiide emarginati. Antennce corpore longiores, 

 apicem versus sensim incrassata? ; scapo breviusculo, articulis 

 tertio et sequentibus cj^lindricis, subajqualibus, ultimo apice ob- 

 tuse. Protho>-a.v cylindricus (in B, collari in medio tumidus). 

 Scutellum semicircularis. Elytra supra planata, prothorace basi 

 multo latiora, apicibus rotundatis. Pedes mediocres vel brevius- 

 culi ; unguicuU valide dentati. Pro- et mesosterna simjjlicia. 

 Abdomen cylindricum, segmentis fere sequalibus. Processus inter- 

 coxalis vix distinctus. 



I have already briefly pointed out the characters of this 

 genus as distinguished from Glenea (Trans. Ent. Soc. ser. 3. 

 iii. p. 365, note). M. Lacordaire places it in the Phytceciinee, 

 separating it from Glenea^ which forms the last '•'' groupe''''^ of 

 his " Lamiides vraies," the " Phytoeciides " being the first 

 ^^ groupe'''' oi the " Phytoeciides vraies." The latter are di- 

 stinguished by their toothed, or cleft, claws ; but as several of 

 the Gleneas have the same kind of claws, and all the species 

 are very intimately connected, I do not think this arrangement 

 a happy one. The type of the genus is Saperda Bohemanij 

 Pasc, with which 8. erythaca is congeneric. The following 

 are all very distinct species, and, like the two preceding, are 

 natives of South Africa. 



Blepisanis porosa. 



B. nigra, pube ochracea dense vestita, nigro-punctata ; capite tenuiter 

 punctulato ; antennis nigris, subtilissime pubescentibus ; protho- 

 race transverse, disco maculis denudatis nigris notato ; elytris 

 concinne sat confertim seriatim punctatis ; corpore infra dense 

 ocbraceo-pubescente ; segmentis tribus iutermediis abdominis 

 utrinque macula denudata signatis. Long. 8 lin. 



Hob. Natal. 



Blepisan is fervida. 



B. subtniter pubescens, capite prothoraceque rubris, confertim punc- 

 tatis ; antennis nigris, subtihssime pubescentibus ; scutello magis 



* Lacordaire regards tlie Longicorns as forming one family, but thinks 

 that their primary groups ought to be elevated to the rank of subfamilies. 

 This rank of subfamily is here used for the first time. In the secondary 

 division the "Prionides vrais" and " Cerambycides vrais'' have no 

 "tribus,'^ but are simply divided into " groupes." The "Lamiides," 

 having no aberrant forms so called, are divided into four " tribus.'" This 

 explanation is necessary, as I consider these "ffroupcs,'^ taking them one 

 with another, fully equivalent to the ^'tribus" of the previous volumes, 

 and, like the latter, I treat them as subfamilies.
