what at the base, where there is a short spine, gradually dilated 

 about the middle, and as gradually tapering toward the end, where 

 they terminate in two spine-like pomts, the outer the longest, the 

 iuner almost a continuation of the notch, between which would be the 

 suture ; the two points curiously rotundate-emarginate. Legs very 

 long and strong, particularly the femora, which are compressed. 

 Tarsi with small pulvillus on end of three first joints ; tarsi of female 

 broader and shorter than those of the malė. 



PSALIDOCOPTUS SCABER, n. S. (Fig. on p. 11.) 



Head between the eyes with a deep line, divided into two in front. 

 Thorax surface curiously undulated, and with the head scarcely 

 rough, although with small scattered warts ; the elytra scabrous, 

 with nunierons small warts ; each elytron with two parallel ridges 

 united behind the middle and a sutural ridge ; margiu of elytra 

 between warty and serrated. Jaws strong, punctured at the base, 

 incurved, sides parallel, inner side short and obliquely cut betweeu, 

 the eutting edge sharp ; a curious tuft of ferruginous hair on tro- 

 chanter ; legs serrated below on femora and tibia, legs more or less 

 scabrous. The whole insect is of a blackish-brown, with ferruginous 

 hairs bordering the inside of the tibiae of the first and second pairs of 

 legs ; thorax beneath, and other parts, liable to be chafed by niotion 

 of joints ciliated with ferruginous hairs. Abdomen somewhat squa- 

 moso-verrucose beneath, a pit behind each scale-like wart, with a 

 short hair proceeding from it. 



Note. The figures were drawn on wood by Miss E. Wing, and are 

 of the size of nature. 



Family Lamiad^. 



Among the Lamioid Longicorns there is a genus containing many 

 finely coloured African species. The genus Tragocephala, Dupont 

 (Dej. Cat. p. 638), vvas first briefly characterized by Laporte in his 

 'Animaux articulees,' tome ii. p. 472. 



Tragocephala nobilis. Lamia nobilis, Fabr. S. EI. ii. 297; 

 Oįiv. t. 11, f. 76; also described by Fabricius as Saperda leeta, 

 1. c. p. 318. Sierra Leone. (Coli. Brit. Mus.) 



Tragocephala formosa. Cerambyx formosus, Oliv. t. 20, 

 f. 153, is another well-marked species from S. Africa, abundant in 

 coUections. (Coli. Brit. Mus.) 



Tragocephala pulchella, Westw. Are. Ent. ii. t. 69, f. 4, is 

 another species from Sierra Leone. (Coli. Brit. Mus.) 



Tragocephala variegata, Bertolom., Aiin. Sc. Nat. 1845, 

 p. 423. S. Africa (luhambere). 



Tragocephala Galathea, Chevr., Rev. et Mag. de Zool. 1855, 

 p. 184, was procured by the Scottish missionaries at Benin, 01d 

 Calabar. 



The Tragocephala angolator^ and T. Lucia, described by 

 Olivier and Newman, belong likewise to this genus, biit are aberrant 

 fornis, as is the Tragocephala trifasciella, described and figured
