V. Harold, 1. c. p. 53, mentions the existence in Mniszech’s collection, 
among less than 50 specimens of Goliathus, of 5 examples intermediate 
between reyius and cacicus, having the decidedly yellowish-brown thoracic 
matting of the latter, and the humeral spots of the elytra connected with the 
apical elevations as in the former. He asks whether these are to be referred 
to an intermediate form, corroborating Melly’s opinion that the two insects 
named are not specifically distinct, or considered a good species; and in- 
clines for the present to the latter opinion. Referring to the possibility of 
hybridism in connexion with this point, Harold remarks that, although 
MdolontJia hippocastani and vidyaris, closely allied but distinct species, abound 
at the same time, and on the same plants, his closest attention for some years 
has failed to detect a single example affording the suspicion of transition from 
one to the other; and he infers that if hybridism under suck favourable con- 
ditions does not occur, or is so rare as to escape notice, in these great numbers 
of the Mdolontha, it is extremely improbable that out of less than 60 of the 
Goliathns no less than 6 should be hybrids, [This instance, however, would 
not seem in any way to corroborate his expressed opinion as to G. reyius and 
cacicus being specifically distinct ; for, if it were possible to prove beyond 
doubt that the 5 examples above mentioned did not result from a crossing of 
those two insects, considered as distinct, the more reasonable view would 
still remain (if anj'^ thing, strengthened by that proof) that they were simply 
the intermediate form of a species of which reyius and cacicus are the two 
extremes.] 
V. Harold (1. c. p. IIG) remarks that the Blcesia lansheryii of Gemm. & v. 
Har. Cat. p. 1287, has only a remote resemblance to the genus in which it 
is placed, and that a new genus must be formed for its reception.
