and forming a long triangular spot. The abdomen and middle of 

 the sterna are red, as he describes, and the species is certainly 

 distinct from P. apicalis, Westw. 1843 (= westermanni, Guer. 

 1844), the typical example of which I have before me. P. theorini 

 is found at the Gaboon and in the Cameroons district, whence I 

 have received examples. It is represented at Old Calabar by a 

 closely allied species with black abdomen'.

MoNOHAMMtrS ? 



A single imperfect example of a species allied to Af. nispator, Fabr. 



CoPTOPS FUSCA, Olivier. 



Many examples of this widely-distributed species. 



PiNACOSTEKNA NACHTIGALI, Harold. 



A species, so far as at present known, confined to the Congo and 

 Gaboon basins. 



QurMALANCA EEGALis, Fabr. 



This common West-African species was obtained in considerable 

 numbers by Mr. Bonny. 



Gelohaepta amckna, "Westw. 



This fine species is found also on the Ogowe and Gaboon. West- 

 wood records it from the Gold Coast ; his figure agrees exactly with 

 specimens from the Gaboon. 



Sternotomis vieescens, Westw. 

 Several examples. 



Steenotomis bifasciata, Fabr. Syst. Ent. p. 175 (1775). 



Lamia imperialis, Fabr. Syst. El. ii. p. 286 (1801). 



Many examples of the common form as found on the Guinea 

 coast. 



Sternotomis variabilis, Quedenfeldt, Berl. ent. Zeits. 1881, 

 p. 289, and 1882, p. 341. 



This very distinct species appears to be abundant on the Aruwimi,

Old Calabar. Two examples. I would have adopted the MS. name P. costata 

 for this species, had not Murray expressly withdrawn that name and stated that 

 his species was certainly P. apicalis, he having compared it with example* from 

 Sierra Leone.
