XyYLOTRUPES GIDEON, Linn. Syst. Nat. i. 2, p. 541. 
Half a dozen specimens, of both sexes; the males in different 
stages of development as regards the cephalic and thoracic horns ; 
compared with individuals from Flores, Penang, &c., I perceive no 
difference worthy of mention, although Philippine and Australian 
specimens differ very considerably. The typical X. gideon inhabits

PuH#XOcHROUS. 
A species not at present determinable, the single specimen agree-

Dr. Beccari at the Aru Islands. 
Fam. Lucanip&. 
CLADOGNATHUS BISON, Olivier, Entom. i. 1, p. 13, tab. 3. f. 6.

and, if Cl. einetus of Montrouzier is but aslight var., as Major Parry 
believes, also in New Guinea, Kei Is., Aru and Woodlark Island.

PassaALus. 
There is in the collection a species, of this or an allied genus, 
which cannot at present be determined. 
Fam. BupreEsTID2&. 
CYPHOGASTRA. 
A species of this genus, which I am informed is about to be de-
