(fig. 5). The model may be a male or female, as in such small- 
sized specimens the male does not bear the long elytral processes 
characteristic of large or medium-sized varieties, the elytra are 
merely produced into short points ; these short points are mimicked 
by the Longicorn very exactly. 
Stegenus dactylon (Pase. ) of the subfamily Agniine is also a fair 
mimic of a large-sized Diurus sylvanus (compare figs. 8 & 4 on 
Plate XX.). As in Wgoprepis insignis, the body is blackish- 
brown streaked with a pale ochreous pubescence (fig. 8a); the 
basal two-thirds of the antenne are clothed with a dense black 
plumosity ; the remaining joints are ochreous and pale in colour. 
Elelea concinna (Pase.), one of the Mesosine, also mimics in the 
same manner a small Brenthid, Avrhenodes sp., as previously 
noted by Wallace, who remarks that it carried its antennze 
“ straight and close together, appearing like a Brenthid.” 
Another of the Mesosine—Zelota spathomelina (described by 
Mr. Gahan in Appendix I. to this memoir)—mimies an Endo- 
mychid, a species of Spathomeles near turritus (Gerst.) (compare 
figs. 57 & 56, Plate XXIII.). The model, which is not represented 
in the Baitish Museum collections, is pitchy-black with two 
reddish spots on each elytron; springing from each elytron is 
a stout spine directed somewhat forwards, forming a very 
efficient defence against the attacks of enemies. It is not 
improbable, moreover, that this beetle is still further protected 
by some distasteful properties, which, at any rate, are possessed 
by the species of the genus Mumorphus of the same family, 
an assemblage of black or purplish insects with conspicuous 
yellow spots. All of these possess a very pungent though not 
altogether disagreeable odour, whilst many exude a yellowish 
acid fluid when seized. The mimic of the Spathomeles is 
coloured in much the same way as its model: on each elytron 
there is a mamilliform prominence, from which springs a poimted 
tuft of delicate hairs, which is curved slightly forwards. ‘These 
tufts so closely resemble the formidable spines of the model that 
a near inspection with lens and finger is necessary to reveal the 
deception. Another Endomychid beetle, Amphisternus mucro- 
natus (Gerst.), is also a probable model of the same species of 
Longicorn. 
The aberrant Trachystola granulosa (Pasc.), which was placed 
provisionally in the subfamily Dorcadionine, with its deeply 
punctured and granulate elytra, presents the general appearance 
of a large black Cureulionid, such as Sipalus granulatus (Fab.), 
Ww ithout, however, exhibiting any very highly modified mimetic 
characteristics, as in the species previously discussed. 
Daphisia pulchella (Pasc.) is a highly conspicuous little beetle 
of the subfamily Phytectine, and is almost indistinguishable from 
two species of Clerid of the genus Callimerus (compare fig. 55 
with figs. 53 & 54 on Plate XXIIT.). 
|The resemblance of the Cleride as a group to widely different 
Coleoptera and to insects of other orders is well known. Looking
