Society, and of these skty-two species (a great portion of wliicli are Indian) many are known only by
solitary indi-idduals, wliereas the circumstances stated by Mr. Benson in his Notes on the Capture of
Paussi at the Cape of Good Hope (Trans. Ent. Soc. vol. 5, p. 30), sufficiently show that if the natural
habitats of these insects were examined, a rich harvest would be the reward of the Entomologist's
exertions; the more especially as the recent researches of continental Entomologists have shown that
very many curious species belonging to other families also take up their abode in ants' nests.

gradually broader and internally serrated ; mandibles inwardly obtusely dentate, cheeks dilated beneath, shutting
in the sides of the mouth ; maxillie with an elongated simple terminal lobe, and the inner lobe produced and setose ;
mentvmi transverse, labium larger, with the fore angles rounded and the middle deeply emarginated, palpi simple.
Elytra at the tips longitudinally channelled and keeled, legs short; spurs, especially of the fore legs, long ; tarsi
distinctly 5-jointed, simple.
Prionophora nigra nitida, apicibus elytrorum castaneo-nigris ; capite et prothorace punctatis, pmictis elongatis ;

receptione pedum anticorum ; metasterno canaU abbreviate impresso.
Prionophora black, shining, with the tips of the elytra chesnut-black ; the head and prothorax punctm-ed, the
punctures small, but elongated ; elytra striate-punctate ; the e.xti-emity of each impressed, the sutm-e, margin and
two carinas in the middle elevated and glossy ; presternum impressed on each side for the reception of the fore
legs ; metasternum with an abbreviated channel in the middle.
Length of the insect, 4 lines. Inhabits India. In the Collections of the British Museum and the Linncean Society.

Cerylon and Bitoma ; body subcyliudric and subelongated ; head small and triangular'; labrum semicircnlai-,
mandibles not porrected, subtriangular, armed with two small teeth below the tip, the middle of the inner margin
being membranaceous ; maxillce with two broad membranaceous ciliated lobes ; mentum quadrangular, somewhat
narrowed in front; labium small, rounded at the tip ; all the palpi shnple, with the tips somewhat acuminate ;
anteunK! short, 11-jointed, the three last joints forming a large laminated setose club, the first joint being very
small, and the last j oint very large and curved ; prothorax rugose, the anterior margin deflexed ; elytra costated ; legs
short,femora broad, spurs elongated (especially in the forelegs); tarsi distinctly 4-jointed, simple; pulviUi wanting.
