flanks of the thorax punctate, and the antenne slightly longer than those of the 
female. The dorsal plate of the supplementary internal segment is in the former 
sex infuscate at the tip and emarginate ; the female has this supplementary segment 
replaced by a very short, quadrate, transparent semimembranous ovipositor. The 
length attained is 15 to 18 m.m. 
I have several males of this species found at Auckland by Lawson, and two 
females from old collections, one of the latter accompanied by a male agreeing 
with the Auckland males. It is the only species known to me with the femora 
fuscescent at the tip ; and though it is apparently the common species in collections 
and is usually named Gimona hirta, Fab., yet I cannot consider it to be the Fabri- 
cian insect, as that author says, specially ‘‘ pedes grisei.” I therefore retain for 
the species the trivial name proposed by Newman. 
(mona villosa, n. sp.—The individuals of this are much larger than those of 
. hirta, and it is a broader insect, not attenuate behind ; the thorax is not in the 
least rounded at the sides, but is straight, or becomes just perceptibly broader 
behind ; it is very deeply furrowed transversely, and the femora are red, without 
infuscation ; the length is as much as 27 or 28 m.m. 
Ihave seen only two examples, one sent from Greymouth some time since, and 
then supposed to be a large example of the preceding species, and an old individual 
obtained from Murray’s collection. These accord with the size and form repre- 
sented by White as Isodera villosa; and there can, I think, be no harm in my 
retaining the trivial name, though it would only confuse the student if the older 
authors were cited as the authority for it. 
Notwithstanding the great discrepancy from the following, I have a suspicion 
this may be only the female thereof, in which case the trivial name will be 
abandoned altogether. 
(mona hirta, F'ab.—I have one male of this. Compared with C4. humilis, it is 
a larger and broader insect, with the elytra not attenuate behind, the femora and 
scape of the antenne entirely pallid. The sides of the thorax are a little rounded, 
the transverse furrows are not quite so deep, and the flanks are opaque, not shining 
as in C4. humilis, and more finely punctured than in that species. The abdominal 
structure is the same as in the corresponding sex of C4. humilis; the length is 
20 m.m. 
This example was sent me several years ago by Mr. Helms, and considered to 
be the common species; probably it may be so in the South island ; and it is pos- 
sible, as already remarked, that Ci. villosa may be its female. 
Sect 2. Prosternum punctate in the male sex, impunctate in the female.
