second, it is in the Madeiran insect scarcely half as 
long: and, also, that whilst the second joint of the an- 
tennal club is, in the obsewrwm, much smaller than those 
which are contiguous to it [as in the typical Anzsoto- 
mide], the species from Madeira has that articulation 
distinctly larger than the preceding one.* Hence, since 
it can be referred neither to the pusilium of Gyllenhal, 
nor yet to the obscurum of Sahlberg, and it clearly is not 
conspecific with either the nanwm of Mulsant, nor the 
brunneum of Brisout (the two other species hitherto ac- 
knowledged as European), Dr. Kraatz regards it as dis- 
tinct; and I may, therefore, cite its amended synonymy 
as follows :— 
Sacium madere. 
Clypeaster pusillus, Woll. [nec Gyll., 1810], Ins. Mad. 
A74, (1854); Id., Cat. Mad. Col. 140 (1857). Sacium 
pusillum, Id., Col. Atl. 91 (1865). Sacium madere, 
Kraatz, Berl. Ent. Zeitsch. xin. (1869). 
Hab.—Maderenses (Mad., Des.) ; in graminosis inter- 
mediis, passim. 
p. 91 (genus ARTHROLIPS). 
: rthrolups obscurus. 
(Sp. 264) Arthroliy b 
From the synonyms of this species the Cossyphus 
obscurus, Sahlb., must be erased,—Sahlberg’s insect, ac- 
cording to Kraatz, being (as above implied) a true 
Sacium, and not an Arthrolips. Hence, since the title of 
obscurus for this sect (assuming it to be identical with 
the south-Huropean one) rests on a mere catalogue (that of 
Dejean’s) it cannot be retained, and we are compelled to 
adopt (as, in point of fact, I did in my ‘ Ins. Mad’ and 
‘Cat. Mad. Col.?) Comolli’s name of piceus instead. And 
I will therefore cite the species afresh, thus:— 
* T called special attention to this fact at p. 90 of the ‘Col. Atl.,’ where, 
judging from the sole material to which I had access (namely, the exponents 
from Madeira), I stated that the only genera in the Corylophide in which 
that particular structure (namely, the reduced proportions of the second 
joint of the antennal club) is not indicated were Sactwm and Arthrolips.
