very prominent. In some the maxillary palpi are single and scaled, in 
others bilobed at the end, and furnished with long pencils of hair. 
Among the species are some with the antennz of the male very strongly 
pectinated, in others there are tufted-pubescent. In some, the antennal 
process is long, covered with long hairs and scales, in others the process 
is hardly indicated. In some, there are 12 veins in the fore wings, in 
others 11 ; in some, the male and female agree in venation, in others 
they are very widely different. In some the fore wings of the male have 
a costal fold and a vitreous spot beneath, others have neither. Sometimes 
vein 1 of the fore wings is furcate at base, sometimes it is not so. Some 
have the cell of the hind wing very short, others of the usual length ; 
some species have ocelli, one at least has none. Some have the hind 
tibiz with two pairs of spurs, one has the end pair only. Some have the 
tarsi spinulated the whole length, others have them weakly spined at the 
end. Some have both wings tufted, some the fore wings only. In some 
the male uncus is hooked, sharp, slender, forked at base, in one species 
at least, obtuse, scutelliform. Altogether the subfamily covering about 
two score species gives a pretty wide range of variation, which makes 
the family a rather difficult one to limit, except by the presence of the 
unique antennal process. 
The first American species known were described by Prof. Zeller in 
Isis, 1848, and for the two species named by him he erected the genus 
Tetralopha. Afterwards species were described by Clemens, Zeller, 
Grote, and myself. Mr. Grote first attempted a systematic synopsis of 
the species, and in the Bulletin of the U. S. Geological Survey, Vol. IV, 
gave the name Lpipfaschie to the group, determined new genera, and 
gave figures of venation of the genera, which, corrected, were published 
in the N. A. Entomologist. Mr. Meyrick has given a synopsis of the 
species of Australia and New Zealand, and described in that synopsis a 
number of genera. 
Those who have endeavored to classify the insects have seemed to 
differ quite widely as to their affinities, and as a consequence have 
catalogued them in widely separated positions. Guenée places his g. nus 
Glossina in the Pyrahdine between Aglossa and Asopia. But Guenée 
knew the female only. Lederer keeps the genus in the same place 
calling it S/ericfa, as Glossina was preoccupied, but says he does not 
know the insects described by Guenée. He, however, has one other 
species of the Lpipaschiine and describing it as Deulerolyla conspicurlis 
places it near and above Bots, undoubtedly looking upon it as belonging 
to the Pyralidine. Mr. Meyrick in his works upon the Microlepidoptera 
of New Zealand and Australia, discusses the group, calling it ** pz 
paschiade,” and concludes it should be catalogued at the head of the
