. One specimen. Allied to the two preceding, but stouter and broader, unicolorous 
black, dull, and very closely, rugosely sculptured, with the head red, very large and 
porrect, with the front margin broadly reflexed and concave ; the species is very distinct 
and ought, perhaps, to be referred to a separate genus, but it has nothing to do with 
Tragopa, and in facies is certainly a Parmula.

The members of this genus, according to St&l, are characterized by the fact that the 
corium has three discoidal areas, and that the apical area is transverse and stylate and 
subtruncate at the apex, and that the thorax is moderately elevated, and the dorsum, if 
viewed from the side, is rounded, acute, and compressed; this definition, however, 
necessitates the removal of several of the species which have been placed under 
Amastris to a fresh genus, as below described.

This is a small unicolorous green species, with the tegmina entirely hyaline, with 
testaceous veins; the pronotum, if viewed from the side, is almost semicircular. 
A. simillima is a closely allied species, but is more or less sinuate and depressed in 
front, if viewed sideways, and not nearly so evenly rounded. Stal has left the genus 
in considerable confusion, for he characterizes five new species as forming a distinct 
group in his synopsis“, without attempting to name or "further characterize them. A 
specimen from Atoyac is figured. 
HYPAMASTRIS, gen. nov. 
Genus precedenti affine, sed dorso depresso haud compresso-carinato, tegminibus plus minusve infuscatis, venis 
crassioribus, apiceque pronoti obtusiori apice tegminum distincte breviori, distinguendus. 
Allied to Amastris, but with the dorsum depressed and not compresso-carinate, and in some cases almost flat, 
and with the tegmina more or less infuscate, and apparently almost coriaceous in parts, with the veins 
very thick and coloured as the prothorax ; the areas of the tegmina appear more irregular, and the apical 
area is nearly semicircular, and occupies the whole apex of the tegmina, the style bisecting the base of the 
segment formed by it. 
The species belonging to this genus are al] small, varying from about 3-5 millim. in 
length ; they are allied to Aygris, Stal, but in the latter genus the corium has only 
two discoidal areas.
