during the early spring months. It is about the size of C. tliapsus, but< 
unlike any of our other species, is uniformly set with greenish-grej 
hairs, with a black discal and smaller sub-apical spot on the suture oil 
the elytra. 
ToMicus ATJTOGEAPHTJS, Eatz., Eorst., i., 160, 7. My friend, Mr. T\ 
Wilkinson, of Scarborough, has sent this fine species to me to bei 
named. It was taken by Mr. Lawson, of the same place, about fivd 
weeks ago, in tolerable plenty, in some young larch trees in a fir planJ 
tation about a mile and a half from Scarborough, where, from the^ 
appearance of the trees, it must have been very abundant last year., 
It belongs to the sub-genus Dryocoetes, Eich., and is allied to villosus, 
being larger and especially broader than that common insect, with the 
hairs not so stout or long, the thorax broader and shorter, the sutural 
stria not so well defined, the apex of the elytra less abruptly retuse, &c.

Note 011 the hahits of Phlceophthorus rhododactylus and Hylastes olscurus.— In 
May, and earlier or later, according to the season, Phlceophthorxis rhododactylus 
makes the galleries in which its eggs are deposited, in the bark of Furze (Ulex 
curopcBus). That the furze be dying, or recently dead, seems the only requisite to 
its attack. I have found it in furze killed by being cut, and in that which appeared 
to have died of old age ; and, though preferring branches about or under an inch 
in diameter, it is found in all— from the largest to the smallest. As branches of 
old and sickly plants die from year to year it attacks them, and probably accelerates 
the death of the plant. It is equally abundant in Broom (Cytisus scoparius). The 
only apparently suitable materials in wliich I have not found it were a number of 
furze bushes smothered out of existence by the rapid growth of some fir trees, 
larch,''aud spruce. 
The gallery is formed directly upwards for nearly a quarter of an inch, and 
then divides into two branches, at first at right angles to each other, but, as they 
go upward, tending to become parallel. They are usually of unequal length, and 
one is sometimes absent. The longest I have seen was less than an inch in length, 
and half-an-inch would be a fair average. I always find in them a pair of beetles 
during their construction, and would note here the analogy with Hylesinus, where 
a two-branched burrow is also associated with the habit of both beetles being 
engaged in its construction. The entrance of the gallery is placed out of sight 
behind a loose scale of bark, or some slight projection. The ejected frass, which 
all appears to have been eaten, lies loosely agglutinated together outside, but no 
operculum covers the opening. I have several times met with an inverted gallery — 
that is, one going downwards instead of upwards from its entrance. The eggs are 
laid along both sides of the branches, twenty-five being a maximum for one side of 
0)10 branch, and the total rarely exceeding forty. The time occupied in their con-
