rected, the two horns of the pronotum much smaller, and the conical tubercle on each side 
scarcely evident, appearing as a slight carina.

Obs. M. Gory’s specimen, from which Count De Laporte drew his description, is now in 
Mr. Hope’s Collection before me, bearing a label, “ Bolboceras ferrugineus, Fabr., Ind. or.” 
Fabricius, however, described no Scarabeus under such a name, whilst the Scarabeus Jer- 
rugineus of Olivier (Ins. 1. Gen. 3. p. 148. pl. 28. fig. 202) does not belong even to the 
present genus, and is from Senegal. It is possible that it may prove to be the other sex 
of B. furcicollis, De Lap.
