Mr. R. Suetrorp showed several insects from Sarawak, 
Borneo, including (i) a Lygeid bug which had been taken 
burrowing in decayed wood: the fore-limbs exhibited a 
remarkable adaptation for fossorial habits, comparable with 
the modified fore-limbs of the mole-cricket (Gryllotalpa), which 
insect in Borneo is frequently found in decayed wood; (ii) a 
Brenthid beetle, with a deep channel running along the dorsal 
part of the prothorax, the lips of which channel are nearly 
apposed, so that the channel communicates with the exterior 
merely by a narrow slit, and constitutes a nearly cylindrical 
chamber; this chamber is occupied by Acari; (iii) two Bren-

the preceding species: and (iv) an Anthribid beetle with a 
crescentic sulcus on the prothorax.

at the same time preparations of some of these perfumes which
