244 HEMIPTERA -HETEROPTERA. 
Subfam. HARPACTORINE. 
This subfamily, the Reduviina of Stal, is the most numerous in species of any of the 
groups of the Reduviide, Lethierry and Severin enumerating 717 species and 137 
genera as belonging to it. Some of the species of Milyas, Zelus, Repipta, Ricolla, &c. 
are common insects within our limits, 
MILYAS.

This genus seems to have its head-quarters in Central America, whence ten species 
are now recorded, two only of the four described forms occurring apparently within 
our limits, the others inhabiting Brazil and the United States respectively. Some of 
them, like the Apiomeri, are very variable in size and colour, and these can only be 
satisfactorily separated by the form of the terminal genital segment of the males. In 
M. zebra and its allies this segment is produced in the centre at the apex and armed 
with a deeply sulcate process, which has the appearance of being formed of two connate, 
slender spines. In M. inermis, M. punctipes, and M. nigropictus the dentiform or 
spiniform process is simple. The outer and inner genital lobes of the males also vary 
in form according to the species. 
a. Femora speckled and annulated with black; posterior lobe of the pro- 
notum tuberculate or granulate. 
a’, Lateral angles of the pronotum with a long spine, the anterior lobe 
with eight long spines: form elongate, narrow . . . .« . . . punctipes, A.&S. 
b’. Lateral angles of the pronotum with a short, stout, backwardly-directed 
tooth: form rather short and broad. 
a’, Anterior lobe of the pronotum with twelve short spines; antennz 
with joints 2 and 3 subequal in length . . . . ... spinicollis, n. sp.

joint 8 longer than2.. . . 2. 2 6 2 6 ee ee ee e) Euberculatus, n. sp. 
4. Femora simply annulated with black. 
c’, Lateral angles of the pronotum tuberculate or nodose, the anterior 
angles with a short tooth, the base strongly bisinuate in the middle ; 
scutellum broadly foliaceous at the apex . . . : . inermis, 1. Sp. 
d’, Lateral and anterior angles of the pronotum each with a short tooth, 
the base feebly bisinuate or subtruncate in the middle; scutellum 
broadly foliaceous at the apex.

and armed with a long or moderately long sulcate spine, the 
genital lobes narrow ; the head with a pale spot between the ocelli. 
a’, Pronotum with the posterior lobe reddish or stramineous, or with 
spots of that colour, the tooth at the lateral angles black . . zebra, Stal.
