434 PHYCIODES. By J. Robbr. 



eremita. M. eremita Wright is usually much larger than leanira. appearing, like that species, superficially some- 



what lilve Araschnia prorsa, but having the spots on the upper surface much closer and brighter. Underneath 

 the forewmgs brick-red, especially in the median area very brillantly spotted, and on the hindwing the ivory- 

 yellow median band of spots very broad. California. 



torightii. M. wrightii Edir. (88 f) resembles exactly the preceding above, but tlie yellow-brown lilotches, particu- 



larly at the base of the fore\\ings, are larger. Underneath, however, the dark intermediate bands are almost 

 completely wantmg on the forewings, which thus represent an ivory-yellow space only interrupted by the 

 black veins and a dark macular band. California; closely allied to leanira. 



miniiia. M. rtiinuta Edu\ (88 e). Dyer formed of this .species, together witli the two following forms, the genus 



Schoenis Hhn., i. e. he only used this little group to preserve Hubner's name, for its oldest representative was 

 only discovered in 1861. mimUa is above uniformly brillant reddish-brown, marked with rows of spots, lunules 

 and .striae of a darker colour. Beneath it so exactly resemldes a small-sized, pale didyma, that it may be 

 considered to be the American representative of that group and cannot possibly be mistaken for any other American 



nrachne. butterfly. From the Rocky Mountains. — arachne Edir. (88 e) seems to be founded upon the low-land form; 

 from Texas; also Colorado. It does not differ very essentially from the main form, but both seem to gradually 

 pass into one another; our figure (a 9) was taken from Holland, who considers arachne as only synonymous. 

 nympha. — nympha Edir. (88 e) is at once distinguished from the preceding by having on the upper surface of both wings 

 a pale yellow band which gives it some similarity to certain phoebe-iormn of Europe. Also the upper surface is 

 more heavily marked with black. But underneath it so closely resembles certain specimens of minuta that its 

 specific rights can only be established by breeding it from the larva which at present is not known. From 

 Arizona. 



The following foims are in part rather scarce or represent species or subspecies founded on single speci- 

 mens, not found even ui the largest collections such as those of the Washmgton Museum. 8ome seem even 

 difficult to connect with the above described groups, and many are only known from the original descrip- 

 tions; the types bemg destroyed, they may not be identified with certainty; others again refer to mere aberra- 

 tions, only the types of which have become known. 



briicei. M. brucei Edw. is nothing more or less than a form of anicia Dhl. a. Hew., established by Edwards ui 



maria. 1888. but not referred to by him later on in his "Butterflies of N. America". Also maria Skinn. is closely allied 

 to anicia which it seems to replace in the central and Avestern States. From Utah. The same holds good of 

 gilettei Barn., described from Wyoming, but not mentioned by Holland in his Work on butterflies of the Uni- 

 hehia. ted States. — helvia Scudd. from Alaska appears closely related to taylori, the ty|3e of which was de- 

 stroyed in the great (.!hicago fire; but Holland assumes that specimens having the median band on the upper 

 surface of the hindwings less distinct, and the ground-colour paler, such as are known from White Horse and 

 sierope. Eagle City in Alaska, belong here. — sterope J^rf^r. seems to be closely related to the lost helvia: estabhshed 

 in 1870 by Edw.\rd,s. it was not mentioned in his later Work on American Diurna, no more than by Holland. 

 neiimoegeni. From Oregon. — iieunioegeni Skinn. seems, like maria Skinn.. to be a form of some other species, perhaps 

 beckeri. palla, changed by the peculiar geological conditions of its home, the District of Salt Lake in Utah. — beckeri 

 Godm. a. Salv. (88 h), from Northwestern Mexico, is possibly only a southern form of hoffinanni, which it al- 

 most exactly resembles above, but with the basal half and terminal borders darker; underneath the ivory-yellow 

 schausi. lunular spots are not separated from the border by a rufous terminal stripe. — schausi Godm. a. Salv. (88 h), 

 although allied to the preceding form, shows on both sides essential differences; especially the under surface of 

 the hindwmgs has the ferruginous bands much larger, and the dark lines traversmg the hindwings are approa- 

 approxi- chmg closely; from Paso de San Juan in Veracruz (Mexico). — approximata Streck. undoubtedly belongs, 

 *"" • like the former, to the same group as gabbii and hoffmanni, being possibly intermediate between these and bek- 

 albiplaga. keri. Described from Texas, but unknown to me. — albiplaga Char, is, hke approximata. not represented 

 in the collections of the National Museum in Washington; a dwarf species, resembling rather a Phyciodes. 

 closely allied to perse and chara, but not so monotonous in colouring. Texas. Holland does not mention this 

 form. 



4. Genus: I*liycio<les Hbn. 



This genus is distributed throughout South and Central America, with a few representatives in the 

 United States. The greater number of species are found in Central America and in the northern part of South 

 America. In accordance with Schatz and Kirby, we unite the Eresia species with Phyciodes, since no funda- 

 mental difference exists either in structure or in the shape of the larva and chrysalis, not even in the most 

 extreme forms. Indeed it cannot be sharply separated even from MeUtaea, which it completely resembles in the 

 shape of both caterpillar and chrysalis. The less well known forms nuxy be easily recognized as Phyciodes 

 by the open cell in the hindwings.
