distant spinules towards its apex (whereas in that genus the apex 
itself is internally armed with six, closely-set ones) ; and their lower 
lip is altogether somewhat longer,—the ligula, moreover, being wn- 
emarginated in front, and the central (divergent) laciniw narrow and 
acuminated. In common with the Caloderw, however, the bodies of 
the Chilopore are densely (though delicately) pubescent ; their tarsi 
are pentamerous, with the basal joint of the posterior pair con- 
siderably elongated ; and their paraglosse do not project beyond the 
anterior angles of their ligula.

C. black, very slightly shining, most minutely and closely punctu- 
lated all over, and densely clothed with a short, decumbent, cine- 
reous pubescence. Head oval, and a little narrower than the 
thorax, Prothorax subquadrate, and rather deeply channeled be- 
hind,—the channel becoming evanescent anteriorly. Antenne at 
base, palpi, and legs, testaceous: the femora, except at their 
extreme apex, more or less darkly picescent. Antenne at apex 
blackish-brown. 
The Madeiran specimens of the common C. longitarsis have their 
prothorax somewhat more evidently channeled than is usually the 
ease in the British ones. The species is abundant in most parts of 
Europe (being recorded in Germany, England, France, Austria, Italy 
and Sardinia), but is apparently very rare in Madeira, where I de- 
tected three examples of it, at the end of June 1855, towards the 
upper extremity of the Ribeira de S Luzia,—beneath stones at the 
edges of the stream.

It is possible that this genus may have, eventually, to be merged 
into Oxypoda; at least it is the opinion of Dr. Kraatz of Berlin 
that at any rate the Y. planzfrons (which alone I sent him for in- 
spection) is not very distinct therefrom. Since, however, the three
