244 NEWSTEADIA FLOCCOSA. 



Long, 3-5 mm. 



Male * (fig. 9) strongly farinose, more especially so 

 at the margins of the abdominal segments. Colour 

 brownish-yellow ; margins of the chitinised portions of 

 the thorax and legs dark brown ; eyes black. Caudal 

 tuft consisting of about sixteen individual filaments, 

 the latter being shortest at the sides. Antennae very 

 long, strongly setose, the hairs in life appearing white, 

 of ten joints ; the first and second joint shortest, 

 normal ; the third to the eighth inclusive much the 

 longest, subequal, the eighth being about two-thirds 

 the length of the third; ninth and tenth joints 

 together equalling the length of the eighth ; formula 

 3, 4, 5, 6, 7, 8 (9, 10), 1, 2. Legs (fig. 10) strongly 

 setose ; tarsus about half the length of the tibia. 

 AYings comparatively large, faintly hyaline, slightly 

 farinose, and by transmitted light finely reticulated. 

 Head, thorax, and abdomen setose ; the hairs on the 

 abdomen arranged in single transverse rows. Geni- 

 talia (fig. 11) large; the outer valves somewhat cheli- 

 form and finely spinose at the apex ; penis-sheath 

 porrected, with a dorsal, subapical dilation, and the 

 apex deeply cleft. 



Larva, after treatment with potash (fig. 12), short 

 ovate, more or less attenuated posteriorly. Gland- 

 tracts forming transverse bands, widest on the cephalic 

 and thoracic areas, narrowest on the abdominal 

 segments. Glandiferous spines resembling those of 

 the adult female. Mentum (see fig. 12) very large, 

 biarticulate, apex reaching from beyond the insertion 

 of the posterior legs ; apical joint nearly as long 

 again as the first. Antennae (fig. 14) geniculate, long, 

 stout, sparsely spinose, and composed of four joints ; 

 the first is much the broadest ; the second either equal 

 to or a little longer than the first ; the third much the 

 shortest, and much narrowed at its articulation with 



* My description of the male is made from examples obtained from an 

 isolated colony of females, so that there can be no doubt as to the identity 

 of the species.
