HYPSELONOTUS.—SPHICTYRTUS. 153 
Hab. Costa Rica, Irazu, Cache (Rogers). 
This species differs from H. concinnus by the black scutellum, absence of central 
levigate line to pronotum, colour of the legs, and black markings beneath, and appears 
to take the place of Mr. Dallas’s species in Costa Rica. 
8. Hypselonotus proxima, n. sp. 
Above black; head, a broad central longitudinal fascia to pronotum and scutellum, on pronotum joining a 
transverse fascia near anterior margin, which is abruptly deflexed on each side, and continued as a narrow 
submarginal fascia to near base, apical margins of clavus and corium luteous. Underside of body luteous, 
with a spot on each side of base of head, three longitudinal series of spots on each side of sternum (one at 
cox and two lateral), five longitudinal series to abdomen (one central and two lateral on each side), and 
two spots on abdominal margin at apices of third and fourth segments black. Femora luteous, strongly 
annulated with black; tibie and rostrum black, tarsi fuscous, with the two apical joints paler. Antenne 
black, with the first, second, and fourth joints subequal in length, third a little shorter. Pronotum and 
corium finely but sparsely punctate, scutellum finely transversely striate. 
Long. 12-13 millim. 
Hab. Costa Rica, Irazu, Cache (Rogers); Panama (Boucard).—Amazons, Pebas (coll. 
Dist.). 
This species is very closely allied to H. linea, Fabr., and in colour and markings 
above is inseparable. It is, however, at once distinguished by the spots to the body 
beneath, and by the much greater length of the basal joint of the antenne than exists 
in the Fabrician species. In a Panama specimen the longitudinal series of spots to the 
sternum have become confluent and linear, the extreme apex of the corium being black. 
SPHICTYRTUS. 
Sphictyrtus, Stal, Ofv. Vet.-Ak. Foérh. 1859, p. 462; ib. 1867, p. 548; Berg, Hem. Argent. p- 88 
(1879). 
This genus is Neotropical, and fairly represented in Central America. Its most 
striking characteristics are the acute posterior angles of the metasternum. The rostrum 
reaches or passes the posterior coxe, as defined by Stal, or the intermediate coxe only, 
as proposed by Berg.

Hab. Mexico !?, Jalapa (Hoge). 
This species is rendered very distinct by the luteous costal margin to the corium.
