Mr. J.S. Baly on the Classification of the EFumolpide. 435 
Scutellum small. Llytra closely soldered together along the suture, 
narrowed posteriorly, convex, often flattened along the back, irregu- 
larly punctured, usually furnished with longitudinal rows of tubercles. 
Legs subelongate, moderately robust ; thighs narrowed at the base, mo- 
derately thickened, each frequently armed beneath with a short tooth, 
the front pair rather thicker than the others; ¢bie often thickened at 
the apex ; this part in the anterior pair more or less incurved; wnguiculi 
appendiculated. Prosternum broad, separated on either side from its 
episterna by a deep groove; anterior episternum scapulariform. 
Type, Dictyneis (Myochrous) pulvinotus, Blanch. Chili. 
The apterous body and soldered elytra divide Dictyneis from 
Myochrous, with which genus in other characters it is closely allied ; 
the insects belonging to it are hitherto found only in Chili and the 
Argentine Republic. The present genus is (as far as our knowledge 
extends) the only apterous one in the whole family of Eumolpide ; 
the insects belonging to it have, from their gibbous and tuberculate 
elytra, a peculiar facies by which they are easily recognizable ; many 
of the species have been described by Blanchard in the Faun. Chil. : 
more recently several others have been characterized by Philippi in 
the Stettin. Ent. Zeit. The collection made in the Argentine Republic 
by M. Germaine, now in my possession, contains a fine series of 
species of the genus, including several new. 
Genus Myocurovs, Erichs. 
Consp. Ins. Col. Peruanz, p. 164. 
Winged. Body elongate, parallel, subcylindrical, more or less flattened 
above, non- or faintly metallic, clothed with adpressed scales or scale- 
like hairs. Head inserted in the thorax, perpendicular; antenne sub- 
filiform, moderately slender, rather longer than half the body, basal 
joint incrassate, second very short, third about equal to the first in 
length ; eyes entire or notched. Thorax above transversely convex, 
flattened in the middle of. the disk, the latter forming a distinct angle 
with the lateral portion; side margin distinct, frequently dilated, its 
outer edge armed with irregular teeth (in some species the anterior 
portion is obsolete); the apical margin sometimes anteriorly produced. 
Scutellum small, Elytra parallel, subcylindrical, more or less flattened 
along the back, not soldered at the suture, upper surface closely punc- 
tate-striate. Legs of normal length, moderately robust ; thighs slightly 
thickened (the anterior pair distinctly thicker than the rest), frequently 
furnished beneath with a short tooth; anterior éébie incurved, often 
armed on their inner surface with a short tooth ; wngwiculi appendicu- 
lated. Prosternum separated on each side from its episterna by a dis- 
tinct groove ; anterior episternum scapulariform. 
Type, Myochrous immundus, Erichs. Peru.
