1902.] SPIDERS FROM BORNEO AND SINGAPORE, 
VI. RHYNCHOTA AS MIMICS. 
a. Rhynchota Hemiptera. 
Mimic. A eduviid, sp. 
Model. Bracon, sp. 
The bug has the elytra, wings, and dorsal surface of the body 
reddish ochraceous as in certain common Braconide ; the abdomen 
beneath is white; the apex of the coriaceous part of the elytra 
is black, thus resembling the black stigma on the fore wing of 
the model; while both elytr a and wings are suffused with fuscous 
as in the model. So perfect is the resemblance between the two 
species that the bug was placed in a cabinet together with several 
other Hymenoptera, and the mistake was only discovered quite 
recently whilst attempting to arrange the museum collection of 
Braconidee. 
Another species, probably of the same genus of bug, mimics 
another similarly coloured species of Bracon in the same manner 
as above described.

(. Rhynchota Homoptera. 
Mimic. /ssus bruchoides (W1k.). Plate XIX. fig. 10. 
Model. Alcides, sp. (Curculionidee.) Plate XIX. fig. 9. 
This remarkable little Homopteron, one example only of which 
is in the British Museum from Sumatra, occurs not uncommonly 
at Kuching on fallen logs or on living wood, whilst the Weevil 
is frequently found beneath the bark of fallen logs, sometimes in 
the very logs on the surface of which is found the mimic. 
The whole appearance of the mimic with its hard convex elytra 
and deceptively powerful legs is very weevil-like, and the resem- 
blance was evidently noted by the describer. The fore legs are 
much flattened and in side-view correspond closely in appearance 
to the powerful fore legs of the Alcides (compare figs. 9 & 10, 
Plate XTX.). 
VII. SPIDERS’ AS MIMICS. 
Mimic. Cyrtarachne conica (O. Pickard-Cambridge), 
Model. 4 mollusc. 
The abdomen of this Spider is many times Jarger than the 
cephalothorax and is dorsally produced into a cone, which appears 
as if tilted backwards. The colour of the inet is creamy or 
yellowish white, marked with fine black and greenish lines ‘and 
mottlings, ari ranged in a somewhat concentric manner so as to 
1 The Spiders here noted were described in P. Z.S. 1901, i. p. 11 ef seq. pl. v. 
Cyrtarachne conica Was W rongly recorded HS occurring in Singapore.
