their length, tibia about the length of the femur ; tarsus about two- 

 thirds the length of the tibia. The tarsal claw is stout, quite 

 strongly curved, and the tai'sal digitules are slender, slightly more 

 than one-half the length of the tarsus and with oblique knobs 

 at the tip. The digitules of the claw extend beyond the tip of the 

 claw, the knob of one being set very obliquely, that of the other 

 straight. There is a long hair at the apex of the coxa ; a long sen- 

 sory hair at apex of trochanter and another shorter one near the 

 base.. The femur bears three or more short hairs and the tibia 

 three. 



The mouth structure is as follows: The mentuiu is raonomerous, 

 almost semi-circular in outline, and bears eight short hairs, only 

 discernible under a high power. The rostral tilaments are very 

 long, the loop when entirely withdrawn reaching well into the 

 abdomen. (See fig. 13.) 



The anogeuital structure (see fig. 11) presents quite a degree of 

 complexity. The ring itself is difl&cult to see as such, as its plane 

 is vertical in position, so that most preparations, as the one figured 

 show only its edge. Tne ring bears eight tapering haii'S, which 

 are not analogous to the ordinary clothing or sensory hairs found 

 elsewhere, but seem rather to be the chitinous stiflTenings to a sort 

 of membranous tube arising fromithe anogenital ring and extending 

 to the middle, nearly, of the dorsal lobes. Putnam (Proc. Daven- 

 port Acad. Sci , Vol. II. p. 293 on) claims that this tube is waxy ? 

 but if so would it have withstood the treatment of boiling in pot- 

 ash and glycerine, which the specimen underwent during prepara- 

 tion? Every other bit of waxy secretion disappeared entirely 

 during the proce^ss. His idea that the tube functions as an egg 

 guide is undoubtedly correct. The dorsal lobes are triangular, the 

 lateral angles forming almost a right angle, and each dorsal lobe 

 bears about nine hairs of the sensory variety, as shown in the figure. 

 A feature which I have never seen mentioned, though possibly oc- 

 curring in other species, is the presence of four large haii's on the 

 abdomen (see figs. 3 and 11), two on either side, a little in front of the 

 anogenital appai-atus. The two anterior ones are farther apart 

 than the two posterior. 



The marginal spines under very high power show, on the part of 

 some at least, a peculiar branched condition at the tip (see fig 14). 

 Those at the stigmatal depressions are in threes, one long, flanked by 

 two short hairs. S The stigmata themselves are situated some 

 distance in trom the margin of the scale, near the coxa of the fore 

 and middle legs, with a sort of groove leading outward to the 

 beforementioned spines This group is filled with a conspicuous 

 line of dense, white cottony wax secreted by glands whose open- 

 ings lie scattered in an irregular row beneath it (see fig 12). 



The ovisac is white, elongated, 8mm. long by 25mm. broad, with 



. sides nearly parallel , conspicuously fluted and with slight tran verse 



markings, apparently impressions of the hinder end of the body.
