Introduction 
veins usually united beyond the middle, the common stem united 
to the commissural margin before the apex of the clavus or con- 
tinuing to the apex of the clavus. The tegmina vary greatly in texture, 
sometimes nearly opaque, with or without semitransparent areas, some- 
times entirely translucent or transparent. The venation of tegmina also 
varies greatly; typically radius, media, and cubitus with supernumerary 
veins, with usually a definite subapical line or two subapical lines of 
transverse veins. Costa arising from the base of the basal cell; radius, 
media, and first and second cubitus all arising from the apex of the basal 
cell. In other genera the venation is greatly reduced, sometimes with only 
a few crossveins on the costal border. The wings smaller than the tegmina, 
venation considerably reduced but cubitus with several branches; cross- 
veins relatively few. Legs simple with the front and middle legs small; 
hind femora large; hind tibiae elongate with one or more spines on the 
lateral margin and the apex with a crown of seven or more apical spines; 
first segment of hind tarsi usually shorter than second and third together 
without spines at the apex. 
The male genitalia have the genital styles elongate, sometimes longer 
than pygofer; when viewed laterally usually with an elongate dorsal tooth 
at or near the apex. Aedeagus usually short and stout with a complicated 
pattern of apical spines and processes. In the few genera that I have 
examined the female genitalia are incomplete; pygofer undeveloped with 
the three pairs of valvulae exposed, the third pair often greatly developed. 
HISTORICAL RESUME 
Twenty-six of the forty-one recorded genera were described by StftI, 
Melichar, and Distant, and these same authors together with Bergroth, 
Germar, Jacobi, Kirby, Kirkaldy, Lallemand, Schmidt, Signoret, and 
Walker are responsible for most of the species recognized in this catalogue. 
Melichar 1923a : 1 20 gives keys to and descriptions of the thirty-three genera 
that were known at that time and a detailed catalogue of the known species. 
GEOGRAPHIC DISTRIBUTION 
All the species in this family with the exception of two are from the 
Eastern Hemisphere. Twenty-four of the species in the present catalogue 
have a distribution covering two or more zoogeographic regions. The 
other species are recorded as follows: 15 from the Palearctic Region, 107 
from the Ethiopian Region, 32 from the Oriental Region, 68 from the 
Malaysian Region, 41 from the Austromalayan Region, 25 from the 
Australian Region, and 38 from the Oceanic Region. 
The known geographic distribution of each species is indicated by super- 
script figures at the end of the lines, which correspond to geographic regions
