stated that the femora were sometimes toothed and sometimes 

 simple. The toothed femora are now known to be a generic 

 character, which I believe does not occur in any American species 

 of Callichroma and its immediate allies.

A forma typica differt thorace supra viridi-aurato, parte antico 

 cum occlpite, antennis pedibusque jjurpttreo-cupreis. 



As E. stranrjidahis is known to vary in colour {conf. Quedenfeldt, 

 Berl. eat. Zeits. 1883, p. 144), the present may be one of its 

 varieties. In the sculpture and colour of the elytra it offers no 

 difference, tt seems, however, judging from the scanty material 

 before me, to be a narrower form with stronger anterior strangu- 

 lation of the thorax, and the scape of the antennae is confusedly 

 scabrous rather than transversely rugose as in the typical form. 



Phrostne brevicornis, Fabr. 



A species widely distributed along the West-African coast, from 

 Sierra Leone to Angola.

Suhgen. Mecometopo proxime a^nis ; frons subelonc/ata, fere

 Long. 10 millim. 



One example. The species seems referable to a section or sub- 

 genus of CJlytus near Alecometopiis. The forehead is rather long and 

 subverticali plane-, with widely open autenual cavities, which leave 

 only a narrow space between ; of antenniferous tubercles no trace. 

 The antenna are about two thirds the length of the body, the joints 

 withoht spines, from the fouirth to the ninth shortened dnd thickened, 

 tenth and eleventh rapidly narrowing. The thorax is subglobular, 

 slightly narrowed anteriorly; very convex and wider than the elytra ; 

 it is free from crests and markings, the long tawny-silky pile laid 

 and convergent. The elytra are parallel, flexuoso-truncate at the 

 apfex, the oiiter angle produ(^:ed in a lohgish spine. The hind lisgs 

 are only moderately elongated, the femora not thicker than the 

 others, armed at the apex with two very short spines.
