116 . SERRICORNIA, [ Campylus. 
CAMPYLUS, Fischer. (Denticollis, Piller; Lepturoides, Herbst.) 
This genus is easily distinguished from all our other Elateride by having 
the eyes very prominent and entirely free, not touching the angles of 
the thorax, and the forehead with the anterior margin sharply raised and 
reflexed; the intermediate coxee are somewhat approximate ; the antennz 
are very long; the thorax is truncate at apex, and the posterior angles 
are not carinate; the genus contains about fifteen species, which are 
confined to Europe, the Black Sea region, Northern Asia, and North 
America ; our single British species stretches across Europe and Siberia ; 
it is very variable in colour, and superficially resembles certain species 
of Telephorus ; the larva is dark brown, slightly reddish; it bears a 
strong resemblance to the larve of certain species of Athous. 
C. linearis, L. (2 mesomelas, L.). Hlongate and parallel-sided, 
colour very variable; male with the head, except front, black, the 
thorax red, occasionally darker on disc, and the elytra testaceous, with 
or without dark suture, rarely black, female with the head and thorax 
as in male, elytra black with borders testaceous, or testaceous with the 
suture broadly black, or rarely testaceous; head strongly punctured, 
antennze long, with the second joint very short; thorax longer than 
broad, very coarsely punctured, with sides rounded and narrowed in 
front, posterior angles sharp, very projecting and divaricate; there is a 
deep longitudinal channel on disc, and two strong transverse impressions 
before base nearly meeting the ‘central channel; elytra with coarsely 
punctured strie, interstices punctured and transversely rugose ; under- 
side black, apex of abdomen testaceous; legs lighter or darker testaceous, 
more or less pitchy, with the femora usually dark, sometimes almost 
entirely pitchy. L. 9-12 mm. 
Male with the thorax narrower and less rounded in front, and the 
elytra narrower and more parallel-sided; female with the thorax broader 
and more rounded in front, and the elytra more ample, somewhat 
dilated behind middle. 
By beating and sweeping in woods, &c.; has also been bred from birch stumps ; 
somewhat local, but not uncommon and generally distributed throughout the greater 
part of England and Scotland, and probably Ireland. Dr. Sharp records it as local in 
Scotland in the Solway, Tweed, Tay, Dee, and Moray districts ; the female appears to 
be much scarcer than the male, as far as my own experience goes. 
DASCILLIDZ. 
This family connects the section Malacodermata or Malacodermi of 
various authors with the Cebrionide and Rhipiceride, neither of which 
families are represented in Britain; the genus Cebrio is rather closely 
connected with Campylus, with which it agrees in having the prosternum 
produced into a process behind ; in fact it is by some authors included 
under the Elateride; on the other hand it bears in many respects a 
strong affinity to Dasctllus, and also to Rhipicera and Callirhipis, which
