The type is figured, contained in the collection of the British Museum. | 
Subfam. PENTATOMINA. 
Pentatomina, Stal, En. Hem. ii. p. 12 (1872); v. p. 28 (1876). 
This subfamily is universally distributed, but reaches its maximum in number, size, 
and coloration in the tropical parts of the Old World. Central America in this group is 
moderately rich, and contains both identical and representative species of the Nearctic 
fauna, which in this subfamily has a strongly marked Palearctic facies, and also possesses 
most of the striking and more beautiful forms of the Neotropical Region: ‘Taking the 
Nearctic and Neotropical faunas together, and comparing them with those of the 
Ethiopian, Oriental, Australian, and extra-European portion of the Palearctic Regions, 
we find that the American Pentatomine compare in a proportion of about one third 
the number of genera, and rather more than three fourths of the total enumeration of 
species. 
MACROPYGIUM. 
Macropygium, Spinola, Ess. Hém. p. 287 (1837); Dall. List Hem. i. p. 150 (1851); Stal, Ofv. 
Vet.-Ak. Forh. 1867, p. 523, En. Hem. ii. p. 12 (1872). 
Oxyrhinus, A. & S. Hist. des Hém. p. 113 (1843). 
This genus contains two species, both peculiar to the Neotropical Region, and both 
found in Central America. The head is armed with a spine near the eyes, and the 
lateral margins from these to the apex sinuated, the lateral lobes of the head longer 
than the central ; the second joint of the antenne shorter than or subequal in length 
to the first.
