much multiplied by one or two authors ; the most important of these 
are Apoderus and Attelabus, which are represented in Hurope by two 
and four species respectively, and in Britain by single species; they 
differ from the Rhynchitina by having the tarsal claws connate and 
thickened at base, and by the formation of the mandibles and the in- 
termediate coxe; their life history is much the same as that of the 
Rhynchitina; the females lay their eggs sometimes under the epidermis 
of the leaves, and sometimes simply on the leaves, attaching them to 
their surface by a viscous substance, and then roll the leaves over them 
into cases, inside which the larve feed, the shape of the cases varying 
with the species, as in Rhynchites; inall cases the final transformations 
appear to take place underground.

This genus contains about a hundred species, which are widely dis- 
tributed in the Old World: the majority occur in Eastern Asia and 
the adjacent islands, but they range from Kamtschatka to Ceylon and 
Madagascar and the Cape of Good Hope, and representatives occur in 
Sumatra, Bornco, &.: outside of the tropics the species become less 
numerous, and Europe possesses no peculiar species; they are easily 
distinguished by the curious form of the head; in the males the head 
is evidently narrower and more contracted behind than in the females 
and less oval, and the anterior tibiz are more slender and less enlarged 
at apex: in the females, moreover, the anterior tibiz are furnished with 
a second terminal claw; Thomson (Skand. Col. vii. 27) says, ‘ Mas. : 
tibiis apice intus unco armatis ; Femina: tibiis unco nullo”: as, how- 
ever, I have taken the sexes together, I can confirm M. Bedel’s state- 
ment (l.c. p. 22): the females have two distinct terminal claws to the 
anterior tibia and the male one large one. SBedel remarks that the 
Swedish authors, usually so exact and accurate, have all through the 
Attelabide assigned the male characters to the females, and vice versa: 
although this does not seem to be always the case, yet it must be borne 
in mind by all students who are working the group with the help of 
Thomson’s “ Skandinaviens Coleoptera.” 
A. coryli, L. (avellane, Steph.). Black, almost glabrous, thorax and 
elytra, and more or less of femora, except base and apex, bright red ; 
head variable in the sexes as above stated, long, channelled, constricted 
into a neck behind, which is closely and distinctly punctured ; thorax
