WALKER, WITH NOTES. 



BY G. H. FRENCH, CARBONDALE, ILL. 



Three days before the last moult, the larva is 1.30 inches ; after the 

 last moult and three days before pupating, 1 inches. Nearly cyiindrical, 

 tapering from the middle to both ends, the under side a little flattened, a 

 slight fold above the legs but no fringe on the sides. The markings in 

 the two last stages are the same, except that the orange is a little heavier 

 in the last stage. The ground colour of dorsum, sides, except below 

 stigmata, and venter sordid white, below stigmata clear white ; striped 

 transversely over the back as low as the stigmata, thus leaving a clear 

 white substigmatal stripe, eight of these stripes and these somewhat 

 double, some broken and others partly continuous ; a subdorsal and 

 substigmatal row of orange patches, two of each row on each joint, the 

 lower on each side of the stigma on the anterior part of the body, but on 

 the posterior part these patches connect above the stigma, gradually pass- 

 ing from one form to the other ; on joint two, instead of two patches, the 

 anterior half of the joint is orange with a row of black spots ; joints three 

 and four with an irregular row of orange across near the middle of the 

 joint. The fold above the legs black, with an orange spot on each joint ; 

 the true legs orange with black tips, each with an obscure white stripe at 

 the base ; the prolegs black and orange, with a white stripe at the base, 

 anal legs orange ; anal plate orange with an anterior row of black spots ; 

 the joint preceding this contains a somewhat zigzag transverse irregular 

 orange stripe with black mottlings. Head olive, with four black longi- 

 tudinal stripes to a side and one in the middle. Venter dull sordid white, 

 rather dark ; the anterior joints, two to four, unspotted but striped trans- 

 versely between the joints with black, the black and white lines going round 

 the base of the legs ; joints five and six striped as above, even with the 

 orange patches, but these paltr than above ; joints seven to ten black be- 

 tween the legs and striped transversely between the joints with black and 

 white ; joints eleven and twelve irregularly marked with black, as though 

 the transverse black lines were broken into dots and dashes, an orange 

 patch containing a black spot on each side of each joint, the orange con- 

 nected with the orange on the lateral fold ; joint thirteen dull blackish ; 

 each of the last three joints with blackish centres. 



The chrysalis is i inch long, subcylindrical, slightly indented on the 

 dorsum of the first abdominal joints, tongue and wing cases extendincr
