E. Tue Tacutnip Fry BENGALIA ATTACKING 
TERMITES. 
[See Proc. Ent. Soc., 1919, p. lii-lviii and references 
quoted, for evidence that Bengalia seeks Termites because 
it is unable to penetrate any but very thin-skinned insects 
or those which have been bitten by ants. See also Trans. 
Ent. Soc., 1906, pp. 394-396 and references, for the habits 
of the allied Oriental Ochromyia jejuna F.| 
Agege. 
Oct. 18, 1917.—One little incident of the great maculatus- 
Lycaenid find [p. 392] I might just add while I remember it. 
When the Termitary was broken up the white ants were 
of course scattered over the ground, and, in no time, I 
am sure there were not less than a dozen Bengalias hawking 
around, to whom the feeble Termites fell an easy prey. 
At Ibadan some time ago I got one of these enterprising 
flies in the act of attacking, successfully, a de-alate Termes 
bellicosus the morning after a nuptial flight, and I have 
even seen them tackle a fair-sized Noctuid larva. 
VI. HEMIPTERA. 
The Procryptic Appearance and Altitude of certain Hemi- 
ptera on an “* Ant-tree.” 
| Unfortunately no specimens were sent and the species 
cannot be identified. Dr. G. A. K. Marshall thinks it is 
fairly certain that the species was a Pentatomid, for this 
family includes several W. African species that frequent 
tree-trunks and are more or less lichen-like. Alelocera is 
perhaps the most likely genus. | 
March 20, 1915.—I found some very curious bugs the 
other day on a tree here. Perhaps Lamborn sent you 
them before. The nymphs were resting on the lichen- 
covered bark of a large tree and looked greatly like a large 
scale insect; they rested on the surface absolutely motion- 
less, and were so like the lichen that I failed to notice 
them during a considerable interval during which I was 
looking at some ants which nest in that particular tree. 
The ants did not seem to mind them. So perfectly quiet 
were they that I thought they were large scale insects. 
Concealed in deep cracks on the bark I found some of the 
mature bugs, not so well protected as the nymphs by 
their colour. This protection, in virtue of their power of 
flight, and their odour when disturbed, the adults would 
not require, though they were by no means conspicuous. 
They rested in groups of three or four together.
