430 RHYNCHOPHORA. [Cryphalus. 
destroyed branch presents the same appearance in an exaggerated form ; 
the whole bark looks bloated and eracked, and is pierced by the exit 
holes of the beetles. A branch is often attacked in sufficient force to 
destroy it in one season, and I have already mentioned my belief that 
the destruction of a whole tree has been accomplished during the present 
season. The trunk is rarely attacked till most of the branches are dead, 
and its vitality is then so much reduced that no distortion occurs from 
their ravages, except of course that it becomes quite decayed.” 
In the ivy growing on these fallen aspen trees Dr. Chapman found 
Cissophagus hederce in numbers ; the occurrence of these two usually 
very rare beetles in abundance and in such close proximity is curious, 
as showing us that probably very few beetles are really rare if only we 
can get to understand something of their habits. 
The British species belonging to the genus may be divided as follows : 
one or two of them are, however, rather difficult to distinguish from 
descriptions :— 
I. Funiculus of antenne five-jointed; club rather elongate 
oval, acuminate at apex; thorax and elytra somewhat 
shiny ; scutellum distinct (Trypophleus, Fairm.; Glyp- 
toderes, Hich.). 
. Punctured striz of elytra not distinct near suture; 
size smaller; legs pitchy . . C. BINODULUS, Ratz. 
. Punctured striz of elytra distinct near suture ; size 
Mlaeet 3; legs in part yellow. . . . C. GRANULATUS, Ratz. 
Il. Funiculus of antennz four-jointed ; club rather short 
oval, rounded at apex ; scutellum very punctiform (Cry- 
phalus, i. sp.). 
i. Club of antenne with the sutures transverse, almost 
straight; body behind thorax only twice as long as 
broad, 
1. Eyes entire; thorax with four transverse rows of 
granules infront . . . . C. Tin, Panz. 
2. Eyes emarginate on their anterior border ; thorax 
confusedly granulate. 
A. Elytra with very short, scarcely visible, hairs ; 
rows of punctures on ely tra not very fine and 
placed in somewhat impressed stria. . . C. ABIETIS, Rafz. 
B. Elytra with long raised hairs; rows of punctures 
on elytra very fine. C. PicEm, Raiz. 
. Club of antenne with the sutures ‘strongly, curved ; 
aie behind thorax three times as long as broad; 
elytra without strie . . . . « »- « « © & » « C. Faal, Nord. 
C. binodulus, Ratz. (asperatus, var. Gyll., sg. Trypophlaus, 
Fairm.). Subcylindrical, black or fuscous black, rather shiny, scantily 
clothed with greyish scale-like hairs and other short hairs; antennae 
and legs pitchy testaceous, club of former often darker than funiculus ; 
thorax subtransverse, ae the sides slightly rounded, anterior margin 
with four prominences in the middle and with concentric rows of 
granules, united in places almost into sharp lines; elytra with feeble
