178 THE CANADIAN ENTOMOLOGIST. 



rest being under joint i, this white band reaching round the sides to the 

 elevation on joint 4, the lateral portion mottled with olive and brown. 

 The boundaries of the light spaces back of joint 4 varying slightly in 

 different specimens, but in all the anterior one reaches on the sides to the 

 first pro-leg. Each side of the dorsum on joints 8, 9, 10 is a dark brown 

 patch with a bright elliptical violet spot in the centre, the patch more or 

 less surrounded with mottlings of white, the last pair of patches nearly 

 surrounded and often partly absorbed by the light that covers the rest of 

 the body. Joints 2, 3, 4 have each four small dots of the same violet 

 hue, while on each side of joints 8, 9 is a cluster of fine blue points. 

 Each joint, except such as are light at this place, has a cluster of these 

 little points below the stigmata. The light space in the middle of the 

 body is more or less mottled with pale olive. Duration of this period 

 to the time it suspended in its loop to change to chrysalis, five days. 



Mature Larva — When full grown length 1.75 inches, \Wdth of widest 

 part, or joint 4, .56 inch, narrowest part, or joint 10, .25 inch, of joint 

 II, .31 inch. The anterior part of body much thickened, a prominent 

 ridge extending across joint i, along the sides and over the back part of 

 joint 4, tne latter being the highest part. Inside of this space is some- 

 what flattened. Back of joint 4 it tapers rather abruptly to the posterior 

 part of joint 5, after which the body is nearly cylindrical. The scent 

 organs about .50 inch, bright dark red. From the time of suspension to 

 casting the last larva skin one day, or more nearly thirty hours. 



Chrysalis — Length 1.50 inches, some a little shorter ; the ventral side 

 strongly arched, the dorsal incurved but not very strongly ; head case 

 long, depressed, the sides parallel, scarcely wider at base, ©cellar promin- 

 ences long, subpyramidal, not divergent, two teeth on the inner edge of 

 each, a dorsal tubercle at the base of each prominence ; mesonotum 

 rather low, edges slightly carinated, anterior elevation bilobed ; abdomen 

 with a subdorsal row of small tubercles. Surface granulated. Color 

 variable. One form gray marked with dark gray and brown, another form 

 pale green marked with gray and brown, the latter color mostly on the 

 head case and down the ventral part of the thorax. 



The pupal period varies. One of the two observed from which these 

 notes were taken produced the imago fourteen days after pupating, making 

 forty days from the time the butterfly was observed depositing the egg to 

 the imago. The other one is at writing still in chrysalis. Fourteen days
