HYPERA.—ISORRHINUS. 3 
1. Hypera ocellata, sp. n. (Tab. I. figg. 1, 2; 1a, profile of head; 14, meso- 
and metasternal side-pieces.) 
Oblong-ovate, black, shining ; thickly clothed above and beneath with small, narrow, grey scales, these becoming 
piliform on the head, rostrum, antenne, and legs, and on the terminal ventral segments, the upper surface 
also with scattered decumbent hairs; the elytra with eleven conspicuous black spots, each surrounded by 
a line of fulvous or ochreous scales—one on the humeral callus, one at the apex, and two on the dise 
of each elytron, and three on the suture (the anterior one of these being immediately behind the 
scutellum),—and a line of ochreous scales along the outer margin ; the head also with a line of similarly 
coloured scales extending round the eyes, except in front. Head densely, very finely punctate, foveate 
between the eyes; the latter transverse, somewhat coarsely facetted, and separated by a space about 
equalling their own length; rostrum stout, about as long as the prothorax, gradually widening outwards, 
densely punctate to near the tip, which is smooth ; joints 1 and 2 of the funiculus subequal in length, the 
scape reaching back to the anterior margin of the eye. Prothorax transverse, barely one-half the width 
of the elytra, narrowed and slightly constricted in front, the sides parallel from the middle to the base, the 
surface densely, very finely punctate. Elytra oblong-oval, truncate at the base, the humeri obliquely 
truncated and somewhat swollen, the disc flattened anteriorly ; finely punctate-striate, the interstices almost 
flat and minutely, rugulosely punctate. Beneath closely, very finely punctate. Ventral segments 1 and 2 
very broadly and feebly depressed down the middle in the ¢. 
Length * 94, breadth 44 millim. (¢ 2.) 
Hab. Muxico, Omilteme in Guerrero 8000 feet (H. H. Smith). 
Two specimens. In its essential characters this insect agrees very well with [/ypera, 
but the general coloration is very peculiar, the elytra having eleven irregularly shaped 
black spots, each surrounded by a ring of ochreous or fulvous scales. The eyes are 
somewhat widely separated. 
ISORRHINUS. 
Isorhinus, Capiomont, Ann. Soc. Ent. Fr. 1867, p. 443 ; Petri, Monogr. Hyperini, p. 5 (1901). 
Isorrhinus, Gemminger & Harold, Cat. Col. viii. p. 2389. 
A genus including a few Mexican species f, and differing from Phelypera in the very 
short rostrum. J. gibbus and J. undatus have the eyes larger and more rounded than 
in either of the forms described by Capiomont, J. gidbus also having the prothorax 
widened behind, the elytra gibbous towards the base, and the legs elongate. It is 
unnecessary, however, to treat either of these insects as generically distinct from 
Lsorrhinus.

I. fuscomaculatus and I. chevrolati are, no doubt, sexes of the same species, one of
