THE “SKIPJACKS” AND THEIR ALLIES. 171 
(which is not superficially unlike the Throscus with 
a similar trivial appellation) skipping about, on 
removing a stone on the shore of Loch Rannoch. 
The north of England seems to be more productive 
of tho larger species than the south ; where, indeed, 
but few of the Elateridce can bo said to abound. The 
malos of some of the metallic species ( Corymbites 
cvprcus and pectinicornis ) have the antenneo very 
strongly fiabellated ; and in Synaptus, Agriot.es .(the 
larva 1 of certain common species of which are known 
as the “ wire-worm ” above alluded to), Sericosomus, 
Dolopius, and Adrastus, the head is almost vertical 
instead of transverse. 
Tho Oampylina have the head exsorted, with the 
eyes very prominent and freed from the thorax; the 
labrum deflexed ; no chin-pieco to the prosternum ; 
tho metasternum .sharply narrowed in front, with the 
intermediate coxae approximated; the mandibles pro- 
jecting, straight at tho baso and curved at the apex ; 
tho last joint of tho maxillary palpi often oval or 
subcylindric ; and the tarsi not lamellated beneath. 
Our solitary species, Campylns linearis, is chiefly 
noticeable from the great variation in colour often 
seen in the female. 
Through this sub-family tho passage is easy to the 
next section, by means of the Cebrionidse, and other 
families not found in Britain. 
M. E. Candcize has monographed tho Elateridx of 
the world in four vols. (Lidge, 1857-G3) ; and his work 
is indispensablo to the student of tho family.
