 9 's we have seen from such localities are red and very similar to the 

 $ 's having generally however the median row of spots of a paler 



color than the other rows. 



M. ARACHNE Edw. 



There has been considerable confusion between this species and 

 minuta Edw. due to misidentifications by W. H. Edwards himself. 

 Arachne was described from a 9 from Colo, received from Reakirt 

 and the type, which we have examined, is in the Strecker Collection. 

 Minuta was described from a specimen from Texas in the collection 

 of J. W. Weidemeyer and Edwards states in his description of arachne 

 that the type is no longer in N. America and that he only has pre- 

 served a coarsely executed lithograph of it, a fact which is probably 

 responsible for the confusion; Mead in the Wheeler Report (PI. 

 XXXVI, Figs. 1, 2) figures as minuta what is really arachne, an error 

 which led Strecker to redescribe the true minuta as approximata; in 

 the Edwards' Collection at Pittsburg the species are reversed, $ and 

 9 specimens from Colorado being labelled 'minuta, type' and speci- 

 mens from S. Colo, bearing the label 'arachne, type' which in view of 

 the localities given in the original description clearly brands these 

 types as spurious. 



Pola Bdv. described from Sonora will take priority over arachne 

 Edw. the figure of the type being excellently depicted by M. Oberthur 

 in Et. de Lep. Comp. IX, 2, Fig. 2188; the species occurs with ap- 

 parently very little variation in Arizona, New Mexico and Colorado. 



Minuta Edw. {approximata Stkr.) is seemingly much more 

 restricted in its distribution ; we have only seen the typical species 

 from Kerrville, Texas but it is quite possible that nympha Edw. from 

 Arizona is merely a brighter and more varicolored race of minuta; 

 the maculation of the underside would certainly point to this. Hol- 

 land's figure (PI. XVIII, Fig. 11) is that of pola (arachne) ; we figure 

 upper and undersides of the true minuta (PI. X, Figs. 4, 7). 



M. callina Bdv. (PI. X, Fig. 11). 



After a careful study of the figure of the sole remaining type 

 from Mexico (Oberthur, Et. de Lep. Comp. IX, (2), Fig. 2185) we 

 have found that the species agreeing best with this figure is the Texan 

 one known heretofore as ulrica Edw. (imitata Stkr.) ; we had suspect- 

 ed from the localities that it would have been the Arizona species
