NEWSTEADIA FLOCCOSA. 243 



the first three only have this character, the fourth 

 being longer and curved outwards, the remainder 

 narrower and straight, adhering to and not separable 

 from the elongate canaliculation of the marsupium ; of 

 the dorsal segments, that next the frontal node has an 

 erect angulated lamina, the next three or four have 

 each a broad, delicate, suberect, forwardly directed 

 lamina, which is deeply cleft, almost divided, in the 

 middle, so that each side appears with a greatly 

 rounded projecting edge ; the other segments straight, 

 with, at most, only a slight trace of lamination; at the 

 anal orifice is a short lamina either lying flat or slightly 

 elevated ; the marsupium varies much in length, some- 

 times being only half that of the rest of the insect, and 

 sometimes, but more rarely, as long as the other por- 

 tion of the insect ; the upper surface canaliculate, the 

 under surface very convex, the end much recurved " 

 (Douglas, 1. c.). Female, after treatment with potash 

 (fig. 4), short, ovate, or subcircular. Antennae (fig. 5) 

 spinose, more or less geniculate, of six joints; first 

 joint longest and broadest ; second and sixth joints 

 nearly equal in length, each about three-fourths the 

 length of the first ; the third joint, which is equal in 

 length to the fourth and fifth together, has a central 

 constriction closely simulating a joint; formula 1 (2, 6), 

 3 (4, 5) ; apical spine slender, pointed. Eyes close to 

 the antennae (fig. 5), tuberculate, and much dilated at 

 the base. Legs long and rather stout, strongly 

 spinose ; tibio-tarsal joint (fig. 6) either straight or 

 faintly curved ; claw short, with a pair of slender 

 basal spines. Mentum (fig. 7) Inarticulate, stout, in 

 prepared specimens often porrected ; apical joint more 

 than twice the length of the first. Anal orifice dorsal, 

 near the margin, with six short spine-like hairs ; ring 

 broadly punctate. Grland-tracts broad, approximate 

 at the margins, but rather widely separated on the 

 dorsum ; marsupial tract (fig. 4 a) more or less cor- 

 date ; glandiferous spines (figs. 8, 8 a, and 8 b) rather 

 long, bluntly pointed, straight or more or less curved.
