244 MR. R. SHELFORD ON MIMETIC INSECTS AND [ Nov. 4, 
XXIII. fig. 40, no. 17 in Table I.), Lie its swollen pedunculate 
posterior femora and white-tipped wings, resembles very closely 
the common little Dammar-bee Moe vidua (Lepel.) (Plate 
XXIII. fig. 41); it is remarkably active on the wing and has 
doubtless often been passed over by collectors, the least important 
of its foes. FH. sarawakensis (18) Wallace found er awling on 
timber, and stated “that they were remarkably ant-like”; in 
this species the posterior femora are not swollen. 
Of the Tillomorphine, Clytellus westwoodi (20) and Halme 
cleriformis (19) are almost indistinguishable from ants. 
Noves on Taste II.—Longicorns mimicking other Coleoptera. 
Excluding, for reasons already mentioned, the subfamilies 
Mesosine and Apomecynine, it will be seen that the Saperdine 
and Astatheine are essentially the mimetic subfamilies in this 
section. Most of the species are extremely common and highly 
conspicuous, and I have little doubt but that all are distasteful, 
and therefore furnish examples of synaposematic coloration 
(Miillerian mimicry). All the species of the genus / ntelopes are 
mimetic. #. glauca (Gueér.), red with black spots (Plate XXIII. 
fig. 32), is quite Coccinellid in appearance (compare fig. 30), 
though more by virtue of its markings than of its shape. This 
association of red colour with black spots is so typically a warning 
coloration, as een by scores of species of Coccinellide, 
that it is impossible to regard the same pattern on a Longicorn 
as anything but pseudaposematic or synaposematic. Entelopes 
n. sp. near wallacei (Pasc.), an entirely reddish-fulvous species, 
has as its model similarly coloured species of the family Galeru- 
cide, Metrioidea apicalis (compare figs. 13 & 14, Plate XX.), 
which, as will be seen, serves also as model for two species of the 
Astatheine. Hntelopes ioptera (Pasc.), with its yellow prothorax 
ane blue elytra, and Hntelopes amena (Plate 0-4 fig. 26), with 
re ldish prothor ‘ax and blue elytra, also find parallels amongst che 
distasteful Galerucide (see the accompanying Table, pp. 249, 243 
also Plate XX. fig. 25). Serixia modesta (Pasc.) and S, pceaiee 
(Pasce.) are unlike any distasteful species with which I am ac- 
quainted; the closely-allied S. prolata (Plate XX. fig. 12) and 
S. aurulenta (Pase.) mimic a small reddish-fulvous "Galerucid, 
Enidia sp. (Plate XX. fig. 11). The genus .Yyaste is interesting 
as it mimics beetles of quite a different nature—the Lycide, 
whose distastefulness I have proved by repeated trials with various 
small mammals and birds. Yyaste is generically separated from 
Serivia by the thickened and pilose basal joints of the antenne ; 
the remaining joints, being of exceeding fineness, are more or 
less inconspicuous; and it is by this means that the thickened, 
flabellate, and short antenne of the Lycide are simulated, whilst 
Ephies dilaticornis (Plate XXIII. fig. 18) and Hrythrus apicu- 
latus var. (Plate XXITT. fig. 8), also mimetic of Ly cide, have the 
antenne shortened and dilated in almost the same manneras their
