are readily separated in the male by several characters. 
M. mexicana has two rather slender pointed horns from 
between the bases of the antennae; the front of head (seen 
from side) is much sloping above; the others have the 
tip more vertical; in one ( hageni ) there are two small 
truncate, hairy plates between the antennae, and the an- 
terior lobe of head has a tuft of hair above ; in the other 
( colhuaca ) there is a small process, with a trilobed tip 
between the antennae, and the basal antennal joint has a 
large lobe at inner base, bilobed above, and in the fore 
wing most of the radial cross-veins are swollen in the 
middle. The female of hageni has two short reddish 
stripes on the middle of vertex; I am not sure of the fe- 
males of the two other species. 
Meleoma hageni sp. nov. 
Figures 12, 33 
Pale greenish; face with a black streak from eye to 
month; last joint of palpi largely dark, lower side of 
basal joint of antenna reddish; the median lobe of vertex 
with two short parallel reddish stripes, not near the eyes ; 
sides of pronotum slightly yellowish brown, a reddish 
brown mark on each side of anterior lobe of mesonotnm. 
Wings with greenish venation, the gradates and costals 
of fore wings wholly black, sectorals, cnbitals, and some 
other cross-veins dark at ends, branches from cubitus to 
hind margin remain green ; in the hind wings the gradates 
and costals dark, most other venation pale. 
Seen from the side the head of the male is short, the 
end blunt, on the part near to antennae there is an erect 
median hairy process ; the portion extending down from 
between the antennae ends in two short, broad flat pieces, 
the outer corner of each projecting more than the rest. 
Each basal joint of antennae is hollowed out in front, 
leaving a lobe at base and tip, this under surface is red- 
dish ; the median lobe of vertex is very broad. 
Pronotum somewhat broader behind than in front, and 
in front a little broader than long. 
The female has the same dark streak in cheeks, the 
palpi dark on outer side, the two short reddish lines on
