Zouus (noy. gen. Zolinorum). 
The insect for which this generic name is proposed has peculiar characters, so 
that its position and affinities cannot be determined with precision at present, and 
must be a subject for fnture discussion; meanwhile it may be treated as forming 
a distinct group, which perhaps will be best placed near the Zabrini, and will be 
ealled Zolini. 
The size is rather small, and the appearance somewhat that of the smaller Pter- 
ostichi, such as Haptoderus or Argutor; the base of the thorax is very closely 
adapted to the base of the elytra, which it overlaps. The basal joint of the front 
tarsus in the male is large, and its front side is produced so as to form an angle 
and make the jot unsymmetrical in form ; the second joint is much smaller than 
the first, but is similarly formed; the third and fourth joints being small and sym- 
metrical in form. The undersurface of the two dilated joints bears fine elongate 
hairs, and the anterior side (7.e. the side most produced) bears also papery-like 
squamze; the middle tarsi are simple, as also are the claws. There is only one 
orbital seta. The mentum and ligula are of ordinary Pterostichoid form, the 
former with a strong tooth in the middle, the latter slightly acuminate in the 
middle, with small paraglossa projecting beyond it on each side. The second joint 
of the labial palpus is very feebly bisetose, the terminal joint about as long as the 
second; rather slender acuminate. The maxillary lobes are not very long, and are 
of very ordinary form; the corresponding palpi are not stout ; the second and third 
joints subequal in length; the third broadest at its apex, where it is rather closely 
connected with the terminal joint, which is slender and acuminate, scarcely so 
long as the third joint. The mandibles are short, and the right one is very ob- 
soletely armed with a single tooth in the middle, and there is a feeble external 
seta. The labrum is transverse, with straight front margin, bearing six sete. 
The thorax is well margined at the sides, and is destitute of tactile sete. The 
scutellum is visible, and its broad short extremity penetrates between the basal 
margins of the wing-cases. The elytra have no erect sete, and no larger lateral 
punctures, except that near the base there are close to the side margin three or 
four feeble punctures bearing very feeble sete. The elytra are not in the least 
truncate, only feebly sinuate near the extremity, and at the point of sinuation 
the thin edge is traversed by an oblique groove. There are no wings, but the 
elytra are not soldered. The prosternal process is short and bent upwards. The 
mesosternal epimera are quite slender, ‘well separated from the coxal cavities ; the 
metasternum small, with short broad episterna; the hind coxe contiguous; the 
-ambulatorial setae of the ventral segments feeble. ; 
It will be seen from the above characters that this imsect departs from the 
Pterostichini by the important characters of the form and condition of the male
