(1. c. PL XV, 132) is again quite erroneous and should be referred 

 to hydaspe Bdv. as far as we can judge. 



A. juba Bdv. 



Judging by the figure of the type published by M. Oberthur (1. 

 c. PI. 262, Fig. 2197) and our knowledge of the type of laura Edw. 

 the latter name will fall as a synonym of juba. The two other speci- 

 mens figured as juba (Figs. 2198 and 2199) are however not this 

 species but probably the Sierran race of snydcri, to which we have 

 already referred. Juba occurs in both silvered and unsilvered forms 

 as is shown by a small series before us from Placer Co., Calif, and 

 this latter form bears such very close resemblance to rupestris that we 

 should not be surprised to find that these two so-called species were in 

 reality forms of one species. Inornata Edw. belongs also without 

 doubt in this group and is possibly the unsilvered form of juba or 

 merely a large rupestris, but our material is too limited to have exact- 

 ly matched the type with any specimen in our series and we must leave 

 the matter undecided for the present. Edwards' figure (1. c. II, Arg. 

 PI. V) gives the impression of a rather larger species than juba but 

 this size of course may be merely individual. All three forms were 

 described from the same general locality, viz. the Central Sierras. 



A. macaria Edw. 



This is placed in Dr. Dyar's list as a synonym of curynome Edw. 

 which is entirely erroneous. The species was described from ma- 

 terial taken at Havilah, Kern Co., Calif, and the types are in the 

 Edwards' Collection ; it is very closely related to laura Edw. and the 

 two are possibly northern and southern races of one species ; we have 

 long series from both Havilah and Tehachapi before us ; Wright's fig- 

 ures of laura and macaria (PI. XV, 133, 135) both refer to this spe- 

 cies, his laurina being the unsilvered form which is quite commonly 

 met with. The true laura, which is a synonym of juba Bdv., as we 

 have already pointed out, is a darker, more heavily marked insect than 

 macaria, although the marking of the underside would point to the two 

 being but forms of one species bearing to each other a relationship 

 similar to that existing in our opinion between montivaga and oweni. 



A. coronis Behr. 



In the Strecker Collection is a pair purporting to be the types of 

 this species and regarding these and other Argynnis types of Behr's 

 describing Strecker states (Lep. Rhop. Het. Suppl. 3, p. 22) that they
