N0.1362. A LEY ROD IDS OF (ALIFOIINIA—BEMIS. 513 



half length of orifice and wider than long, with a pair of short .spines 

 on the latero-ccphalic angles; lingiila as long as the orifice, spatulate, 

 the distal part with thro(^ pairs of lateral lol)es and a terminal lol)e; 

 the entire organ densely setose and with two pairs of long hairs — a 

 pair from the angles between the distal-lateral and the terminal lobes 

 projecting caiidad l)eyond the orifice, and a pair on the lateral margin. 

 On the ventral surface the reduced legs are distinct, l)ut only faint 

 outlines of the antennje can be made out. 



Piijxi-cnse. — Average size, 1 by 0.6 nun.; elliptical, narrowed cepha- 

 iad, caudal end truncate; dorsal secretion usuall}' a confused mass of 

 white wax; under a lens it is seen to be made up of numerous long, 

 delicate, asbestos-like wax filaments, which ai'e from two to four times 

 the width of case and matted together, forming the ver}- characteristic 

 CO veering of this species. This secretion can be easily brushed off and 

 quickly dissolves in alcohol. When the case is removed from the h^af 

 there is left a short, vertical fringe. Color of case a dull amber-yellow 

 to dark l^rown. The latter color is probably due to parasitization; 

 dorsum convex and covered with papilhv and pores of various sizes; 

 near the margin they are more numerous and closer together. On 

 the central region they are not so evident, but each segment has a 

 transverse row; scattered among- the papilhe are many small pores. 

 On the abdomen, each side of the dorsi-meson, there is a longitudinal 

 row of large, semitransparent spaces. The thoracic and abdominal 

 segments are distinct, the posterior abdominal sutures strongh' reflexed 

 caudad, the thoraco-abdominal suture sinuate and extending to margin 

 of case; the longitudinal cephalo-thoracic suture is also evident; cepha- 

 lad of the vasiform orifice are two strongly chitinized thickenings in 

 tergum which arc darker and broader than usual, and within the abdo- 

 men are seen two large, orange-yellow visceral glands. There is a 

 pair of short, delicate hairs on the cephalic margin of case, a pair of 

 somewhat stouter ones laterad of the anterior margin of the vasiform 

 orifice, and the usual caudal and latero-caudal seta^, the former reduced 

 to minute hairs. Vasiform orifice subcordate, anterior margin straight. 

 On the inner lateral and caudal margins there are corrugations or 

 folds, which extend downward and inward; operculum not as broad 

 as the orifice and more than half its length, i-ounded on the anterior- 

 lateral angles. Near the lateral margins of the free, distal end i;* a 

 long, stout spine, which projects beyond the margin of the orifice; 

 lingula spatulate, as long as orifice, distal part enlarged and with three 

 lateral and two terminal lobes, apex bearing a pair of long hairs. 

 Eye-spots large, constricted, and dark red; legs reduced, unsegmented; 

 antenna^ short, stout, unsegmented and tapering to a slender point. 



Adult female. — Bred from segregated pupa cases. Length of body, 

 1.6 mm,; wings, too crumpled to measure; hind tarsus. 0.28 mm. 

 Color of abdomen, pale yellow; head and thorax darker, frons brown-
