(iii) The rare Lamiid Cylindrepomus laetus, Pasc., var. Figured 
by Mr. Shelford as Cylindrepomus? form of comis, Pasc. 
(pl. 2x, £33): 
“ Professor Poulton has attached some interesting remarks 
on the far-reaching mimetic effects of this Caloclytus-pattern, to 
Mr. Shelford’s account of the association (/.c., pp. 250-2). It 
is therefore pleasant to record the entry of a member of a 
totally distinct family of Coleoptera into this synaposematic 
combination, thus affording an instructive comparison with 
the first Clerid-Longicorn instance given above, in which the 
Clerid functioned as model instead of mimic. 
“2. Between Hispids and Longicorns. 
“On a recent collecting expedition up the Limbang River in 
Sarawak (April 1910), we were fortunate enough to capture a 
little Longicorn which bore a remarkable resemblance to the 
spinose Hispidae of the genus Dactylispa. Dr. Chr. Aurivillius 
has kindly examined it for me, and finding it new to science, 
he proposes to describe it (or has already described it) under 
the name of Plaxomicrus hispoides (Phytoeciinae).* I send 
with it for exhibition a specimen of the common Hispid, 
Dactylispa longicuspis, Gestro, which was taken in the same 
district and month (possibly on the same day). It should be 
noted that all the Sarawak Museum examples of this species 
of Dactylispa come from the region watered by the Limbang, 
Trusan and Lawas Rivers, all of which are adjacent and 
debouch into Brunei Bay. 
“The little tufts of hair on the elytra of the Longicorn, so 
formed as to resemble the spines on the Hispid, recall the 
instance of another Longicorn (Zelota spathomelina, Gahan), 
exhibiting a somewhat similar development (but bearing of 
course an entirely different pattern from that of the Hispid-like 
Longicorn), on this occasion in mimicry of the spined Endo- 
mychid, Spathomeles turritus, Gerst. Mr. Shelford figures and 
records this latter instance (/. ¢., p. 247, pl. xxiii, f. 56, 57). 
He also mentions the presence of the larger red and black 
Hispidae with mimetic Longicorns in his great Lycoid dis- 
tasteful association, but I believe that this is the first instance 
* Mr. C. J. Gahan considers that the species more probably belongs 
to the allied genus Chreonoma.—E. B. P.
