pone carinam verticalem ; prominentiis in parte anticä pronoti minis distinctis, lineáque longitudinali 
posticä obliterata ; capiteque corpori concolori.— Long. corp. lin. 73. 
Obs. Captain Parry possesses a rather smaller specimen, with the central impressed lon- 
gitudinal line of the prothorax less distinct, the lateral tubercles near its anterior angles 
not so large, but covered with minute punctures, as is also the front of the prothorax, and 
the front of the head has the angles more emarginate.

B. grandi valdé affinis at magis globosus, capite et pronoto magis granulato-punctatis. Caput latum, 
cariná recta transversä ad basin clypei alteráque abbreviatä recta inter partem anticam oculorum. 
Mandibulæ late, dextra ante apicem profundé incisa, lateribus tenuibus, recurvis, nigris. Pronotum 
versus marginem posticum parüm levius, carina curvatà medianá prope marginem anticum, tubercu-

profundä et sublevi in medio lateris utriusque. Elytra levia, gracillimè striato-punctata. Tibiæ 
anticæ late, dentibus 7 nigris obtusis. 
The insect which has served for the above description appears to be a female, and is 
closely allied to the preceding. I am unable, however, to surmise whether the male is 
one of those deseribed in the subsequent portion of this memoir, or is still unknown.

me Mr. Melly possesses a specimen exactly agreeing with the male in Mr. Hope's Col- 
on, figured above, which he received from Comercolly, in the East Indies. He also 
possesses a second specimen, from Thibet, very slightly smaller, having the cornuted pro- 
cesses on the prothorax very slightly smaller, the space between the two porrected points 
of the clypeus nearly straight, and not sinuated, agreeing in its colour with Mr. Hope’s 
es DO ORA : Cyclops, except that of the tips of the spines of the fore-legs and 
“CHERS v d ca whieh are black. A third specimen is also in Mr. Melly's 
d t, of an intermediate colour, exaetly agreeing with them in general 
characte and punctation, but having the anterior angles of the clypeus very slightly por-
