NEOCATTARUS. 213 
ledge of the Order, I have here failed to interpret his meaning sufficiently to prevent 
confusion. 
As defined by Stal, the “ Rhyparochromaria,” in his restricted sense, is separable from 
the preceding division here enumerated by the absence of the distinct collar at the 
anterior margin of the pronotum, of which the lateral margins are generally more or 
less carinate, but not ampliated. The “ Beosaria” are distinguished by these lateral 
pronotal margins being more or less laminated and ampliated, and having the antenne 
nude, or sometimes slightly pubescent, which in the “ Gonianotaria” have the three 
basal joints rigidly hirsute or setose. The “ Lethearia,” with which Stal himself incor- 
porated his division ‘ Drymaria,” are stated by him to be differentiated from all the 
preceding divisions by the following character :—“ Lateribus segmenti quarti ventralis 
maculis opacis duabus, a margine postico segmenti longe remotis, interdum quoque 
posterius macula opaca tertia instructis.” After a prolonged study with all these divi- 
sions, and especially with the last-named, I have found Central-American forms which 
did not rigidly appertain, so that it was possible, by wrong divisional differentiation, to 
add confusion to the study of the whole group. I have, however, without using these 
divisional names, endeavoured to group the species in accordance with Stal’s views, not 
so much (in my opinion) for their special classificatory value, but rather for the aid 
thus afforded to the study of faunistic affinities and distribution, as Stal has in this way 
enumerated the different extra-European species with which he was acquainted. 
NEOCATTARUS, n. gen. 
Head, including outer margin of eyes, a little broader than anterior margin of pronotum. Eyes prominent. 
Ocelli situate at base of head, and separated from each other by about twice the distance that separates 
them from the eyes. Antennz with the basal joint more or less passing the apex of the head, second 
joint about or a little more than twice the length of the first. Rostrum about reaching intermediate 
cox, first joint subequal in length to that of head. Pronotum strongly and transversely constricted, the 
anterior lobe narrower but a little longer than posterior lobe. Costal margin of corium concavely 
sinuated. Anterior femora incrassated and spined beneath. 
This genus appears to be allied to Cattarus, Stal, and Pamphantus, Stal, from both 
of which it. differs by the length of the second joint of the antennz and of the 
first joint of the rostrum, and the relative proportions of the pronotal lobes. From 
Cattarus it also differs by the position of the ocelli, and from Pamphantus by the 
sinuated costal margin of the corium. 
1. Neocattarus firmus, n. sp. (Tab. XIX. fig. 19.) 
Head and pronotum dull opaque black ; posterior lobe of pronotum somewhat paler, and with the lateral and 
basal margins narrowly dull ochraceous ; head and anterior lobe of pronotum indistinctly rugulose, poste- 
rior pronotal lobe sparingly but distinctly punctate. Antenne ochraceous, the apical joint somewhat 
infuscated ; second joint longest, third and fourth a little shorter than second, and subequal in length. 
Scutellum dull opaque black, the disk gibbous and sparingly punctate; apical half, excepting central 
carinate line, very coarsely and thickly punctate. Clavus piceous, with a large black apical spot. Corium
