Egg. Approximately circular in cross section, elongated, slightly 

 more pointed at one end, clear pale yellow in color, of smooth and 

 somewhat polished texture; length .22 mm.; cross diameter .11 mm.; 

 deposited in a strongly adherent irregular mass; examined and meas- 

 ured at 100 X. 



Lari'a. Slender, almost cylindrical ; smooth, pale, but darker than 

 knabi and of a decidedly brownish rather than yellow-white tone; head 

 darker, tending toward pale ferruginous ; eye-spots black, prominent, 

 sub-oval, not so obviously formed by the fusion of two spots as in 

 knabi; antennae inconspicuous, shorter than in knabi: mandibles and 

 labium dark brown, the former with five teeth proportioned as in knabi 

 (Knab's illustration), the latter with a single pair of small teeth 

 medially (not two pairs as in knabi) followed by a series of larger 

 ones ; claws of anterior and posterior prolegs yellowish-brown, in form 

 as in knabi; dorso-caudal papillae slightly darkened and much lower, 

 smaller, and less conspicuous than in knabi, in height about once their 

 diameter, and armed with fine black setae which are often appressed 

 into apparently one ; some of these setae are frequently broken at var- 

 ious lengths or entirely missing, and the normal full number is prob- 

 ably six; four retractile anal blood-gills on the twelfth segment; length 

 before pupation about 7 mm. 



Pupa. At first pale, soon darkening to dull brown and then to 

 almost black with the pigmentation of the enclosed imago ; of the usual 

 form, with enlarged thorax but without projecting respiratory tubes or 

 filaments ; caudal end broadened, paddle-like, partly cleft, the two 

 flattened lobes held in the same plane and rounded, each with three 

 fine black setae usually appressed and appearing as a single tapering 

 bristle on its exterior edge; the abdominal segments near their dorsal 

 posterior edge have a fringe of short stout downward-pointing spines, 

 amber-colored tipped with brown. The pupa is naked and quite active, 

 travelling over moist surfaces with considerable facility. The duration 

 of this stage is very short. 



$. Smoky brown to black; antennae 14-jointed, strongly plum, 

 with black hairs, the disc-like basal joint more densely colored 

 than the remaining somewhat translucent joints; eyes black; palpi four- 

 jointed, the first joint shortened and bulb-like, the remaining three of 

 approximately equal length, the first three joints bearing long hairs, 

 the last joint with a few very short fine ones. 



Thorax dark, concolorous, and with three lines of hairs springing 

 from minute polished black rounded granules, the median line poster- 

 iorly abbreviated at less than half the length of the mesonotum, the 

 lateral lines broadening and terminating only slightly in advance of the 

 scutellum ; a minute double pit medially, in line with the termination of
