Coleoptera of the Family Rutehide. 547 
(nearly rectilinear), very finely punctured, 4+ millimetres 
broad and 5 millimetres long. Elytra very delicately 
but distinctly and rather closely punctured ; the margin 
is incrassate below the shoulder only. Pygidium closely 
and rather strongly vermiculate-striolate. The sternal 
process is long and very thick, obliquely truncate at the 
apex (viewed laterally), curved on the side next the 
anterior coxe. The sides of the metasternum and the 
metathoracic epipleura are rather strongly, moderately 
closely, vermiculate-striolate. The sides of the abdomen 
are similarly sculptured, but not quite so strongly so. 
Hab. Ecuador (Buckley). 
Evidently very near Chlorota psittacina, Burm., but 
the punctuation is quite distinct; and although (by 
moving the insect about) four lines may be traced on 
each elytron, these lines are not punctured; the sternal 
process is not at all clavate. 
Chlorota euchloroides, Murray, is very close to this 
species, but differs in having the thorax less angular at 
the sides; the anterior angles are not so prominent nor 
so acute, and the elytra, besides the ordinary punctua- 
tion, has the whole surface closely marked with exces- 
sively small punctures, which in some lights look elon- 
gate; the tarsi are coppery. The sternal process is very 
similar, but the angle next the coxe is a little more 
acute. 
4. Thyridium scutellatum, 0. 8. 
Ovale, crassum, convexum, viride, subtiliter punctu- 
latum ; scutello subcordato. Long. 14 lin. 
Allied to Chlorota psittacina, Burm., but very distinct 
from all the species of this group known to me on account 
of the form of the scutellum. Punctuation on the front 
of the head very fine and moderately close, becoming 
closer and stronger up to the front margin. Thorax 
7 millimetres long in the middle, delicately and_mode- 
rately thickly punctured, the punctures more distinct 
towards the sides; gradually narrowed anteriorly from 
very near the base; when viewed from above it does not 
appear the least angular at the sides, but when seen 
laterally there is a very obtuse angle; the base in the 
middle is broadly but very slightly, arcuately emarginate, 
gently oblique on each side, and gently bisinuate. 
Scutellum 6 millimetres broad at the base, very gently
