at thorax; widest at 2nd abdominal segment, and subacute at anal extremity; tle- 
clivous at 5th or Gth abdominal segment. 
Head the same, more rounded posteriorly, black, nearly as wide as the thorax, 
bearing scattered minute tubercles from each of which arise single, moderately long 
setae; head hispid, surface subscabrous. ( )celli inconspicuous; antennae the 
same, imserted below the center of the face, the finst joint pale, the third joint pale 
at apex, the appendix pale; antennae retractile. IMandibles the same, relatively 
broader, darker, subtriangular, the outer margin subsinuate and more straight, the 
inner emarginate, the teeth stronger, the outer one slightly shorter, the inner or 4th 
more obtuse, nearly truncate. Maxillary pal[)i with basal joint pale. Clypeus 
broad and narrow. 
Thorax narrower than in instar I, in proportion to body; the same. Legs the 
same, stouter, the claw fuscous. 
Abdomen convex, oval, naked, ambulatorial, but with a single pair of prolegs 
situate at anal extremity; segmentation more or less distinct, ventral surface eon- 
cave; ninth segment ])rehensile. Anus terminal. Cerci alxsent. 
Body marked as follows — Head, cervical shield, some of the tubercle areae, 
legs, and anal shield, black, the latter rather dusky; cervieal shield paler, subochre- 
ous near cephalic margin; remainder of the body ochreous. The prominent 
black tubercles and spiracles are arranged as follows: — 
Segment I — The oval, dusky spiracle is on lateral aspect, contiguous to the 
base of the leg. 
II — 2 areae on lateral aspect in a line cephalo-caudad, the more dor- 
sal one larger; 4 on the dorsum in a square; 2 linear areae on 
each side of the meson. 
Ill — The same; the two lateral areae in a line ventro-dorsad, the 
dorsal one much larger. 
IV-XI — I^ateral aspect, two large rounded areae in a line ventro-dorsail, 
snlietpial, forming a double line of dots along the side of abdo- 
men; the dorsal ones are s]iiraeles. On segments IX, X, and 
XI, paler, 1 )rownish, the dorsal areae much smaller (minute 
on XI and near anal shield), but more black. 
Remaining areae very minute, but a longitudinal line on sides of ventum of 
abdomen are inclined to be conspicuous (segments IV-X). Anal shield (piadrate, 
including segments XI and XII, forming a rectangle on each segment. A nunlian 
line of black, fading caudad.
