REPORT OF THE STATE ENTOMOLOGIST IQI2 201 
to the South American Haplusia Karsch from which it is easily 
separated by the unidentate claws. 
Antennae with 14 segments, the cylindric fifth with a length 
about twice its diameter and a stem not longer than wide. Palpi 
quadriarticulate, the segments short. Wings long; the supernumer- 
ary vein extends beyond the middle of subcosta, which latter unites 
with costa at the middle of the wing. There appears to be a distinct 
crossvein, the third vein joining the margin beyond,the apex of the 
wing. Tarsi quinquearticulate; claws fuscous, toothed, the two 
portions nearly equal and strongly bent ; pulvilli wanting. Ovipositor 
not produced, with 2 gradually tapering lamellae, each about three 
times as long as broad. The larva is remarkable because of the 6 
small, triangular teeth internally on the diverging subtriangular 
major lobes of the breastbone; shaft well developed. Reared from

This genus was erected for several small forms apparently allied 
to Colpodia Winn. A closer study of the species, however, shows 
that circumfili are absent and compels us to refer this genus to the 
Heteropezinae. The short first tarsal segment, the antennal and 
alar structures indicate a relationship to Haplusia Karsch, from 
which it is easily separated by the simple fifth vein. This is a re- 
markable synthetic form, since the arrangement of the long setae 
on the antennal segments closely approximate that of the peculiar 
crenulate whorls in Campylomyza, while the venation alone would 
lead one 10 refer it at once to the Epidosariae. Type J. rubra 
Felt. 
This genus appears to be related to the Australian Chastomera 
Skuse, though the latter is remarkable because of the third vein 
being widely distant from subcosta.
