26 HEMIPTERA-HETEROPTERA. 
Distinguished in all its variable forms from the preceding species by the rostrum, 
which reaches the centre of the abdomen. Prof. Uhler (Bull. U.S. Geol. & Geog. 
Surv.), “ List of Hemip. of the Region west of the Mississippi River, including those 
collected during the Hayden Explorations of 1873,” figures (in an outline drawing only) 
Augocoris seepunctatus (pl. 19. fig. 8), but does not include the name of the species in 
his enumeration. In the absence of any information, we may therefore conclude that 
it does not extend to the Nearctic Region.

Stal has described two varieties of this species from Surinam. It can always be 
distinguished by the length of the rostrum, which about reaches the apex of the 
abdomen. | 
Subfam. ASOPINA. 
This well-marked subfamily is well represented in the Neotropical Region; and if to 
this we add the Nearctic, to which very few genera are entirely confined, we have an 
area which possesses nearly half the known genera of the whole world; and of this 
portion nearly two thirds are also represented in Central America. But it is in the 
Neotropical Region that the Asopine reach their maximum in brilliancy of coloration ; 
nor are they inferior in size or structure to those of the more eastern regions, thus in 
these respects offering a complete contrast to the preceding subfamily Scutellerine, but 
affording agreement with that group in the fact of correlation in coloration between 
great brilliancy and excessive variation. 
STIRETRUS. 
Stiretrus, Laporte, Ess. Hém. p. 75 (1832) ; Dall. List Hem. i. p. 76. 3; Stal, Ofv. Vet. Ak. Forh. 
1867, p. 496. | 
Stiretrosoma, Spin. Ess. Hém. p. 356 (1837) ; Dall. List Hem. 1. p. 76. 2. 
This genus is distinguished by the long and broad scutellum, reaching nearly to the 
apex of the abdomen, which is armed with a spine at the base. The anterior tibiz are 
dilated in all the species here enumerated. The species found in Central America 
number only rather more than one fourth of those comprised in the genus, which is 
mostly represented in the Colombian and Amazonian Subregions. One species is 
common to Central America and the South Nearctic Region.
