dark patch, hump on the nth shaped hke the tooth of a saw,, 

 slanting forward, almost perpendicular behind, velvet black,, 

 cleft at the top. Beyond the 9th segment the body appears flat 

 and pointed and the anal prolegs extend back almost horizontally 

 when at rest spread like a <. To the naked eye the prevailing^ 

 color, olive mottled and striped in many shades. Above the line 

 of the stigmata the ornamentation is divided into seven broad 

 longitudinal stripes, the stripe down the middle of the back in 

 light shade, then on each side one darker, one lighter and the 

 lowest almost black. Between each stripe a line light line, almost 

 white in places. These markings all clearer and more pronounced 

 on the thoracic segments. Color below light with a black ventral 

 stripe broken into a spot on each segment. Under a 25 mm. 

 glass, piliferous spots almost entirely white, still with a single 

 black hair each. Stigmata dark and inconspicuous with no light 

 ring. The whole body appears mottled or marbled in purplish 

 brown and yellow and yellowish green, the dark longitudinal 

 stripes appearing where the dark colors prevail and the light 

 stripes vice versa. The skin wrinkled with a look like that of a 

 snake. No further development was observed and the foregoing 

 represents the mature larva. 



By July 4 all but one in the cage with the dirt had disappeared, 

 while those in the battery jar were grubbing in the sand and' 

 under leaves and refuse. These had shrunk to half their length.. 

 In the course of a few days these larvae pupated, some in slight 

 cocoons of f rass and sand and others bare upon the surface. Evi- 

 dently in nature pupation takes place underground. 



Pupa. — Length 23 mm. ; diameter 7 mm. Length of thorax 

 and wing cases 11 mm. Main cremaster short and thick with a 

 round hook almost closed. Two or three much smaller auxiliaries- 

 with ends wound up like watch springs. Color dull brown in 

 some cases inclining to mahogany. Stigmata visible with a 

 strong glass. On the whole the pupae looked singularly smalL 

 Larval period average 30 days. 



April 26, 1 91 7. Two moths emerged, making the pupal period 

 295 days, which was extended to May 14, when the last moth 

 appeared. From some 50 or 60 well-grown healthy-looking 

 larvae only 14 moths were obtained, 4 males and 10 females.
