totomicus; and he is further of opinion that it may possibly 
be, in reality, but a large local form of the C. duplicatus, 
Sahlb. (=rectangulus, Hichh., in litt.). 
p. 239 (genus APHANARTHRUM). 
In my definition of this genus (vide Ins. Mad. 292; 
1854) I stated, unreservedly, the funiculus to be 3-arti- 
culate; and it was not until seven years afterwards, when 
compiling a paper on the “ Huphorbia-infesting Coleop- 
tera of the Canary Islands,” for the ‘Trans. of the Ent. 
Soc. of London,’ that a re-examination of several of the 
antennee (carefully mounted in Canada Balsam) convinced 
me that in reality only two joints were distinctly appre- 
ciable,—although in one species (the Madeiran A. eu- 
phorbie, from which my original diagnosis was drawn out) 
I fancied that I could still trace a third, infinitesimal 
articulation between the second one and the club: and 
this led me to the conclusion that it would perhaps be 
safer to regard the funiculus of Aphanarthrum as only 
bi-articulate,—though, at the same time, adding the 
qualification ‘‘ that in one species, at all events, there are 
indications, beneath a high microscopic power, of what 
may possibly be an additional jomt at the base of the 
capitulum.” And I then remarked that “when thus 
emended, the diagnosis will better accord with what is 
likely to be observed ; whilst the fact of an extra joint 
being faintly indicated in one of the exponents will leave 
it an open question whether the funiculus may not in 
reality be triarticulate, even though but two joints are 
distinctly traceable in the various members of the group” 
[vide Trans. Ent. Soc. Lond., 3rd ser., i. 165; 1861]. 
Under these circumstances it is satisfactory to notice 
that Ferrari, in a paper published in the ‘Berliner Ent. 
. Zeitsch. in 1868, came to much the same conclusion,— 
remarking (p. 254) that the A. Jube, canariense, and 
euphorbicee appeared to him to have a 2-jointed funiculus, 
while in the luridus the funiculus seemed to be indis- 
tinctly triarticulate. 
Taking the above considerations into account, I cannot 
altogether endorse the suspicion of Leconte (Trans. Am. 
Ent. Soc. 11. 152) that the Hylastes pumilus of Manner- 
heim, from Alaska, which forms the type of Eichhoff’s 
genus Dolurgus (Berl. Ent. Zeitsch. 147 ; 1868), should
