sides towards apex, evenly pubescent; scutellum small, subtransverse ; 
elytra more than double as long as thorax, parallel-sided, with the suture 
thickly clothed with greyish-white pubescence, punctured striz regular, 
interstices furnished with short erect whitish sete; abdomen clothed 
with thick greyish pubescence, second segment about twice as long as 
third. L. 23-3 mm. 
Under fir-bark ; very rare; near Scarborough (R. Lawson) ; it does not appear to 
have been taken in any other British locality. 
This insect superficially resembles Hylastinus obscurus and more 
closely Polygraphus pubescens, from both of which it may be separated 
by its generic characters ; from C. hederw it may be known, apart from 
its 5-jointed funiculus and not bilobed third tarsal joint, by being 
usually darker, and by its more elongate form, and by having the elytra 
less abruptly rounded behind, with the punctured striw less clearly 
defined and the sete on the interstices not so stout orlong ; the anterior 
tibiz, moreover, are more triangularly dilated and have only two.or 
three teeth at the apex, and the antenne are stouter and shorter. 
The species has been placed in our British catalogues under the genus 
Carphoborus, Eichhoff, but Eichhoff includes under the latter only the two 
species C. minimus and C. pind, and adopts the genus Xylechinus for 
pilosus ; the characters of the two genera are as follows: 
Antenne with five-jointed funiculus and short oval nou-com- 
pressed club. Anterior cox placed apart. Hyes with 
outline almost entire in front. Third tarsal joint simple . XYLECHINUS, Chap. 
Antennz with five-jointed funiculus and narrow compressed 
club. Eyes reniform, deeply hollowed in front. First tar- 
sal joint very short, the third slightly cordiform. Thorax

Only four or five species have been described as belonging to this 
genus ; two occur in Hurope, one in North America and one in Madeira 
(the latter perhaps being synonymous with our species) ; the single 
British species is a very small pitchy-black insect with reddish tarsi; the 
club of the antenne is rather loose and consists of three joints, the 
funiculus being 5-jointed; the prosternum is very short before the 
anterior cox ; the abdomen is not raised towards apex ; the episterna 
of the metasternum are elongate and rather narrow, and the intermediate 
and anterior cox are rather broadly distant; the third joint of the 
tarsi is bilobed and scarcely broader than the preceding. 
The life history of P. rhododactylus has been most carefully worked 
out by Dr. Algernon Chapman and described by him in the Entomologist’s 
Monthly Magazine, vi. (1869), p. 6; his remarks on the species are here 
quoted at length :—‘‘In May, and earlier or later, according to the 
season, Phlaeophthorus rhododactylus makes the galleries in which its 
eggs are deposited in the bark of furze (Ulex Europeus). That the
