288 THE CANADIAN ENTOMOLOGIST. 



has the spots that compose the white mesial band on hindwings reduced 

 to mere streaks of white on the nervules. No doubt this has received a 

 species name. But one of the Juarey examples is plainly Ardema, of 

 Reakert : " hindwings black, with an indistinct orange-brown shade across 

 the disk." 



Mr. Cockerell wrote 9th Sept.: "On the college farm, yesterday, I 

 found a batch of Synchloe eggs on the under side of a sunflower leaf. 

 They are like the eggs I sent before. They are like the eggs of Melitsea, 

 as figured by you in Butt. N. A. Synchloe seems to be practically a 

 Melitaea in its earlier stages. I send one example of larva, black with 

 numerous yellow-white dots, a sub-variety of the black type. I found 

 several such." 



During the season I had also received several batches of larva? of 

 Phyciodes Carlota, from Montana, and eggs of same from Colorado, and 

 the larva; from the Crocale eggs were reared at same time with the others, 

 so that I was able to compare the two species step by step. The eggs of 

 the two are in no way distinguishable, nor are the larva; in the first two 

 stages ; as regards shape and armature they are alike in the succeeding 

 stages, but differ in coloration. But the pupa of the Synchloe is not like 

 that of Car/ota, which is of the typical Phyciodes shape and appearance, 

 and like Tharos, but is closely like the pupa of Melita;a Baroni, as given 

 in Butt. N. A., Vol. Ill , pt. 3. The stages are described as follows : — 



Egg. — Similar to Phyciodes Tharos: obovoid, truncated at top, 

 rounded at bottom, the lower three-fifths, or about that, examples varying, 

 covered with irregular shallow indentations ; the upper part ribbed, about 

 twenty-four ribs, not much elevated, not sharp, the interspaces roundly 

 and shallowly excavated ; top slightly depressed ; colour when first laid 

 pale green, later changing to green-yellow. Laid in close clusters side by 

 side in several rows. In the cluster under view each complete row (4) 

 contained just nine eggs, and there were shorter rows on either side of 

 these; on the top was part of another layer, placed irregularly and more 

 or less on their sides. These eggs were believed to have been laid 8th 

 Sept., or on the day when found, and hatched on 15th, or after six days. 



Young Larva. — Length at one day from egg, .06 inch; cylindrical, 

 even, each segment well rounded ; furnished with many tapering black 

 hairs, or processes, of which those on segments 3 and 4 are in cross line 

 on the middle, four on either side above the spiracular line : on 2 is a 

 black oval chitinous paten on top of dorsum, on which are six shorter
