attached (fig. 12 b). The genitalia require much further study 
before we can place the family with any certainty. 
The frons is broad, generally broader than long, and the 
lateral margins angular. In some genera there is a costal area 
with cross-veins, in others it is absent. The claval vein runs to 
the apex of the clavus, which is generally roundly closed; the 
vein proceeds beyond the clavus and ends in the hind margin 
and is sometimes branched. The third claval vein (An3) 1s 
sometimes present as a free vein in the apical half of the clavus; 
Cu2 or claval suture continues beyond the clavus, branches and 
terminates in the apical margin. The anal area of the hind-wing 
is reticulate in a few species.

This is a very homogeneous family of about sixty genera. 
The chief characteristics of the family are the claval vein reach- 
ing the apex of clavus, which is closed; the hind margin pro- 
duced beyond the apex of clavus; the tegmina, when at rest, 
very slightly tectiform or nearly horizontal, and the areas 
beyond the clavus overlapping. In only a few genera is there 
any sign of a costal area, and then there are no cross-veins. 
The female has an incomplete ovipositor. In the male the 
pygofer is considerably flattened horizontally, there is generally 
a pair of processes on the medio-ventral margin; the genital 
styles are large and complex; the aedeagus in EHurynomeus 
granulatus (fig. 23) consists of a periandrium which is pro- 
duced into three pair of processes, and a penis which is a small 
tube with two long, flat processes (fig. 23 a). In a large Philip- 
pine Achilid at present undetermined (fig. 26) the periandrium 
and penis are fairly normal, but the apodeme forms a long, 
semi-chitinous tube, the nature of which I do not understand. 
A great deal more work must be done upon the family before 
its correct position in the superfamily can be demonstrated. 
Certain points place it near the Eurybrachidae and Fulgoridae, 
but there are others which separate it very decidedly.
