Plectroscapus himaculatus, n. 8. (PL IX., fig. 5). 

 Fuscus, pube breve fulvo-brunnea obtectus ; capitis prothora- 

 cisqiie lateribus et articulis basalibus antennariim siibtus, cinereis ; 

 elytris sparsim punctatis, singulis macula nigro-vehxtina longe 

 pone medium. Long. 26 mm. ; lat. 9^ mm. 



Hah. Old Calabar. 



Dark brown, with a short fulvous pubescence which, on the 

 elytra, is mixed in places with grey. "With the first three joints of 

 the antennae underneath, the pro- and mesosterna, and the sides 

 of the head and prothorax ashy-grey. Elytra sparsely punctured ; 

 each with a distinct velvety black spot placed on a slight promi- 

 nence at abov;t the posterior fourth. Each of the first four abdo- 

 minal segments with a small white pubescent spot on each side ; 

 the last segment feebly sinuately emarginate at the apex. 



The unique specimen of this interesting species is 

 probably a male ; and the curious spur on the scape of 

 the antennse may, perhaps, be a sexual character. 



Thylactus insignis, n. s. (PI. IX., fig. 6). 



Fulvo-brunneo dense pubescens ; capite supra macula spatulata 

 nigro-velutina ; elytris punctatis, dense brunneo-pubescentibus,

Hah. Bathurst (W. Coast of Africa). 



Clothed with a thick fulvous brown pubescence, somewhat 

 paler in parts. Head with a distinct velvety black spatulate spot 

 above. Prothorax armed on each side with a strong and sliarp 

 tubei'cle, in front of which is an indistinct pale fulvous and slightly 

 oblique vitta. Elytra, through the thick brownish pubescence, 

 appearing finely and sparsely punctured ; with a paler pubescence 

 forming on each three oblique lines, of which one from behind and 

 below the shoulder curves upwards and backwards on to the disk, 

 the remaining two, straight and almost directly transverse, placed 

 one behind the other on the posterior fourth ; with a triangular 

 velvety black plaga at the margin on the middle of each side ; 

 apices somewhat truncate near the suture, externally broadly 

 rounded, slightly dilated and fringed with short black hairs.
