and of the dorsal vein extends far into it. On the upper side of the 

 secondaries the orange forms on the dark ground very broad macular 

 bands. (4). The discal stigma of the male is longer than in Comma, pro- 

 portionately narrow, its upper end pointed and distinctly bent, not so 

 straight as in Comma and in the other American species. (5). In the 

 female, two dark-brown spots, separated by the second nervule, stand out 

 very prominently on the bright ground in the disk of the primaries, and 

 between them and the dark margin is a broad space of clear orange. In 

 Comma % the two spots are also present, but mostly united, and cohering 

 with the dark spot below the apex of the wings ; but the two spots are not 

 so dark nor so sharply defined and prominent as in Ji/lm, and they are 

 separated from the dark margin, not by a broad bright space, but usually 

 only by a narrow macular band. The under side of the secondaries is in 

 Jului as strongly sprinkled with fuscous as the variety Cate?ia, and has 

 also equally large, bright, white checkered spots. In one female (from 

 California), the arrangement of these spots corresponds with Comma 

 (Catena); in the other three, the row of spots is more irregular and 

 broken, while the spot between the 4th and 6th nervules is quite separated 

 from the 6th cell, and is placed nearer to the margin. In two specimens 

 (male and female) the spots are united. Evidence is thus afforded that 

 the form and order of these spots, even in specimens undoubtedly closely 

 related, are subject to great variation. 



Juba is in a/iy case a very iuell-)narked local form of Comma. If a 

 comparison of a sufficiently large nnmber of specimens should prove tJte 

 above mentioned differences, or even a part of them, to be constant, then 

 Juba mii:;ht even claim to rank as a species. It is probable however that 

 transitions will yet be found. 



I'he few specimens of Nevada, Colorado and Manitoba which 1 am 

 able to compare (2 of Nevada, 7 of Colorado and 2 of Manitoba) of 

 course justify no positive decision as to Mr. Scudder's assumjjtion that 

 they are true species. / can only say that their differences are not clear 

 to me, and that the exanples sent to me, as well as Mr. Scudder's figures, 

 give me the impression rather of varieties than of specifically distinct 

 forms. Henceforth I will class them together in order to compare them, 

 as a whole, with Comma. 



In the size, shape, color and markings of the upper side of the wings, 

 as well as in the form of the discal stigma, I find no variation from 

 Comma ; but in one particular none of the conpared American insects
