ments. Dorsum covered with a large number of very minute pores, 

 which show as transparent dots. There is a pair of setae on the 

 second abdominal segment and a pair cephalolaterad of the vasiform 

 orifice. Some of the pore-Uke spots on the other part of the dorsum 

 may also be the seats of minute setae, but if so we are unable to 

 observe them owing to the dark coloration of the case. The vasiform 

 orifice (fig. 10) is triangular in outline, with the cephahc margin 

 almost straight; the operculum is similar in shape and almost entirely 

 fills the orifice, obscuring all but the tip of the lingula. This last 

 is setose and armed with two spines. The caudal inner membrane 

 of the orifice is sculptured, and this sculpturing is visible below 

 the hngula; surrounding the vasiform orifice is a differentiated 

 area consisting of a rounded portion directly cephalad of the orifice, 

 from which two arms extend caudad, one on each side of the orifice, 

 forming a caudal channel (fig. 10). The legs (fig. 11) are dis- 

 tinctly visible on the under surface of the case. Each is short, 

 thick, and armed with a pad-like structure on the distal extremity. 

 The antemiae (fig. 13) are subcyhndric, composed apparently of three 

 segments, imbricated, and armed on the distal extremity with a nar- 

 row finger-hke process, and a distal spine. The margin of case (fig. 

 12) bears a series of fairly even crenulations. These are not prom- 

 inent, and the submarginal area is marked by a series of lines extend- 

 ing mesad, which gives it somewhat of a fluted appearance. On each 

 of these sections a fight spot may be observed near the margin, which 

 spot seems to be the opening of a pore beneath. Scattered over the 

 submarginal area there are a number of minute transparent spots 

 similar to those on the dorsal area and on some of these small setae 

 are located; on others, however, we are unable to find any. 



Adult female. — Length from vertex to tip of ovipositor about 0.960 

 mm.; color yellowish, shaded with dusky. Eyes dark brown, con- 

 stricted in the middle. Antennae (fig. 19) of seven segments; II 

 subpyriform, 0.045 mm. long, and usually armed with three stout 

 spines; III subcyhndric, 0.114 mm. long, imbricated, and armed with 

 a few faint transverse sensoria, and near the distal extremity there is 

 a circular fringed sensorium with a central process; IV subcylindric, 

 0.024 mm. long; V similar, 0.033 mm. long; VI similar, 0.036 mm. long; 

 VII subcyhndric, tapering distaUy, armed at about the distal third 

 with a number of minute circular fringed sensoria, and the distal 

 extremity tipped with a spine. Forewing (fig. 15) about 0.95 by 

 0.38 mm. : radial sector curved, cubitus long, and fairly distinct; wings 

 marked with rusty red, which forms two broken transverse bands, a 

 distal spot over the tip of the radial sector, and a broken proximal 

 one over the cubitus; margin beaded and bearing hairs. Hind wing 

 with only one faint red spot in about the middle, below the vein. 

 Vasiform orifice (fig. 16) broadly cordate, with the cephahc margin
