rior to lateral constrictions, two |)osterior t(j same, anil a short 

 one in the middle between the four, or more or less elongated be- 

 hind, between the posterior two. Legs 6-jointed, not including 

 the very small terminal subjoint ; each leg terminated by a jiair of 

 elongate, strongly hooked claws, borne on the subjiWnt. None of 

 the legs with suckers. The sixth joint of legs bears on outer side 

 before tip, a tubercular projection of the surface with hairs, the 

 joint being suddenly narrowed at this tubercular eminence. 'I'his 

 narrowed terminal portion of the sixth joint sometimes appears 

 like an extra joiiU. Length iS to .S.75 mm ; greatest anterior width 

 5 to 6 mm. 'I'hree alcoholic specimens. Color noted in life. 



Fourth stiiio^c. — Differs only in integument being more filled 

 out, lateral constrictions somewhat more pronounced, shape some- 

 what more elongate, oval excavation without raised edges, dorsal 

 dejiressions absent, faint, or shallow. S|)iracles same. Color nearl\' 

 same, slightly lighter bluish. Length, 6.25 106.75 mm.; greatest 

 anterior width, 4 to 4.25 mm. Three alcoholic sjiecimens. Color 

 noted in life. 



TItiiti s/(ii;<\ — Color bluish gray, more oval in shape, not 

 swollen, body narrowed i)osteriorly, spines of anterior half more 

 closely approximated both on dorsum and on venter, giving the 

 surface a more spinose and prickly appearance ; hairs of posterior 

 body thicker. Mouth parts same, but less sunken, the oval hollow 

 being less apparent, the palpi and rostrum more extended and 

 more plainly seen from above. Three short longitudinal impressed 

 lines on venter posterior to last pair of legs, the two outer lines 

 diverging posteriorly from the median one. Spiracular tubercle 

 hardly more jirominent. Length, 3 to 4.5 mm.; greatest anterior 

 width, 2.25 to 3 mm. Five alcoholic specimens. Color noted in 

 life. 



Stioiii/ Sfai^c. — Nearly shape of preceding stage, but smaller, 

 and wholly whitish. While the above stages are all more or less 

 coriaceous, the present one is almost fleshy. Mouth parts same, 

 but not sunken, the capitulum exposed, at least the mouth ring 

 visible, and palpi and rostrum entirely visible from above. Spines 

 of anterior half of body above and below whitish, concolorous with 

 body, posteriorly directed. On ventral surface, anterior to the 

 three longitudal lines and situated between the third pair of legs, 

 is a pair of oblong spots, each marked by an elongate circlet of 

 blackish dots, median posterior line being also defined by similar 

 dots. A pair of exactly similar spots, each marked by a circlet of 

 of dots, on dorsum ; and also a loiigitutlinal median line, marked
