150 HEMIPTERA-HETEROPTERA. 
2. Cebrenis robusta. (Tab. XIV. fig. 20.) 
Cebrenis robusta, Stal, En. Hem. i. p. 200. 5°. 
Hab. Mexico!; GuatEema.a, Capetillo, San Gerénimo (Champion). 
The figure is that of a Guatemalan specimen, which only differs from a typical Mexican 
one in the Stockholm Museum by the irregularly clouded base of the pronotum. 
8. Cebrenis modesta, n. sp. (Tab. XIV. fig. 21.) 
Pale ochraceous, coarsely punctate. Antenne with the second and third joints longest and subequal in length, 
fourth darkest and incrassated. Pronotum with the lateral margins and an obscure central longitudinal 
levigate impression, apex of scutellum, lateral margin of corium, underside of body, and legs luteous. 
Abdomen above red, with some fuscous spots about centre of disk. Rostrum concolorous, slightly passing 
intermediate coxe. 
Long. 9 millim. 
Hab. Guatemata, Capetillo, Guatemala city (Champion). 
This species is allied to C. robusta, but differs from that species by the narrower form 
of the body, the straighter and less sinuated margins of the pronotum, the different 
colour of the upper surface of the abdomen, &c. In some specimens the disk of the 
corium is paler in hue, somewhat indicating a transverse fascla—a varietal character 
exhibited in many allied genera. 
HYPSELONOTUS. 
Hypselonotus, Hahn, Wanz. Ins. i. p. 186 (1831) ; Amyot & Serville, Hist. des Hém. p. 241 (1848) ; 
Dallas, List Hem. ii. p. 450, 1852; Stal, Ofv. Vet.-Ak. Foérh. 1867, p. 548. 
Hypselonotus differs from Cebrenis in having the third and fourth joints of the antenne 
subequal in length, and the thorax provided with a distinct collar. 
This is another purely Neotropical genus; and most of the described species are found 
in Central America. In a systematic sense the genus is an unsatisfactory one, the 
differenti specifice being mostly of colour and markings, good structural differences 
being apparently absent; but if a broader view be taken, Hypselonotus is a genus still 
remaining in a plastic condition, its species exhibiting a constancy of character which 
is superficial rather than structural. 
The species described by Walker, Cat. Het. iv. p. 144. 23, under the name of 
Hypselonotus armatus is merely a Mexican specimen of the genus Nematopus, which 
has been previously figured in this work. 
1. Hypselonotus punctiventris. (Tab. XIV. fig. 23.) 
Hypselonotus punctiventris, Stal, Stett. ent. Zeit. xxiii. p. 297. 161*; En. Hem. i. p. 201. 2”, 
Hab. Mexico! ?,Valladolid, Yucatan (Gaumer); GuaTEMALA, San Gerénimo (Champion). 
The type in the collection of Dr. Signoret is here figured. This is a very variable 
species: in the Guatemalan specimens now before me the longitudinal black strie of
