infuseated. Pronotum luteous, with a distinct, narrow, pale, levigate collar at anterior margin; the 
anterior transverse levigate callosities margined on each side by a row of closely arranged, small, dark 
punctures ; remaining surface coarsely punctate, with two large fuscous spots at base, near lateral angles, 
and the lateral margins very narrowly fuscous. Scutellum black, with the apex luteous, coarsely punctate, 
with two yellow levigate spots at base, and a broad central levigate fascia, which about reaches apex, 
but does not extend to base. Clavus luteous, with two rows of coarse punctures along its outer margin, 
and a single row of the same on apical portion only of its inner margin. Corium pale luteous and sub- 
hyaline, punctate along the radial suture, and thence along the apical margin to apex; apical margin 
fuscous, excepting about the centre, where it is luteous. Membrane very pale hyaline. Abdomen above 
luteous, with a broad central black fascia. Underside of body and legs luteous; sternum thickly covered 
and shaded with dark punctures. Rostrum pale luteous. 
Long. 33-4 millim.

This subfamily is divided from all others of the Lygeide by the character of its 
members having the anterior acetabula remote from the posterior borders of the 
prosternum. Three genera are found in America, two of which have only been 
received by us from Central America.

In this genus the femora are either wholly unarmed, or (more rarely) the anterior 
femora are obsoletely spinous; the apical margin of tbe corium is straight. These 
characters separate Ischnodemus from the two other American genera. 
Two species are here enumerated as found in Central America. Walker (Cat. Het. v. 
p. 127) described a Mexican species in this genus under the name of Jschnodemus 
longus. Neither type nor example of that species now exists in the British Museum ; 
and as Walker’s species can only be recognized in systematic entomology where types 
can be examined, as the genera in which his species are placed are so frequently erro- 
neous, this species of Ischnodemus(?) must be considered as non-existent.
