HEMIPTERA-HETEROPTERA. 405 
SCYTHINUS, gen. nov. (To follow the genus Ceneus.) 
Body somewhat elongate, but moderately broad. Antenne with the basal joint very long, considerably passing 
the apex of the head; second joint almost as long as the first, a little longer than the third; second and 
third joints obscurely hirsute. Head a little longer than broad, distinctly exserted behind eyes, and with 
a small rounded protuberance on each side of inner margins of eyes. Pronotum with the base rather more 
than twice as broad as the anterior margin, constricted at middle, the posterior lobe punctate, the anterior 
margin coarsely punctate. Scutellum without a central carination; clavus and corium coarsely punctate. 
Anterior femora unarmed. Rostrum reaching the intermediate coxe, with the basal joint about as long 
as the head; second joint about as long as the first (imperfectly seen; carded specimen). 
It is somewhat difficult to define the exact position in the Neotropical ‘ Rhyparo- 
chromaria’ that this genus should occupy. By the exserted head it would seem to 
approach the Ozophora of Uhler, but differs from that genus by the unarmed anterior 
femora. 
1. Scythinus splendens, n. sp. (Tab. XX XV. fig. 17.) 
Head, pronotum, and scutellum reddish-ochraceous. Corium ochraceous, with the apex and a spot near centre 
of lateral margin purplish-black. Membrane ochraceous. Antenne with the basal joint reddish-ochra- 
ceous ; the second and third joints fuscous; the apical joint stramineous, with its buse and apex very 
narrowly fuscous. Body beneath reddish-ochraceous ; rostrum and legs ochraceous. 
Long. 3 millim.

CLIGENES, gen. nov. (To follow the genus Scythinus.) 
Head inserted to the posterior margin of the eyes; antenne with all the joints moderately incrassated, first 
joint just passing the apex of the head ; pronotum strongly constricted in the middle, the anterior lobe 
broader than the posterior lobe, the basal margin distinctly concave; scutellum moderately large and 
without a central carination ; clavus longitudinally punctate ; corium coarsely punctate, broadly truncate 
at its inner angles, and from thence somewhat convexly rounded to apices, 
The peculiar structure of the corium will serve to distinguish this genus, of which I 
am unable to describe the rostrum and under surface, owing to the typical specimen 
being carded. 
1. Cligenes distinctus, n. sp. (Sab. XXXV. fig. 18.) 
Ochraceous ; antennz, anterior lobe of pronotum, and scutellum castaneous ; head, lateral angles of pronotum, 
a spot near centre of lateral margins of corium, apex of corium, and membrane blackish; apex of 
scutellum ochraceous, preceded by a blackish spot; body beneath blackish or dark castaneous; the legs 
ochraceous. The posterior lobe of the pronotum is coarsely punctate, the lateral margins of the corium 
are impunctate; the antenne have the first and third and the second and fourth joints subequal in length. 
Long. 23 millim.
