200 THE entomologist's KECORD. 



Cupido pheres, Bdv. — Typical p/ieres is readily recognisable by its 

 peculiar shade of blue at base of wings in the J and the single row of 

 white round spots on underside of secondaries; the outer margin of 

 secondaries in t? is at times slightly suffused with pale grey- blue as 

 is usual in the 2 . 



There is a tendency for the white spots of the underside to become 

 quite distinctly pupilled with black, and 3- specimens of this form are 

 very hard to separate from those forms of icarioideA where the black 

 spots tend to obsolescence. A fairly safe means of separation seems to 

 be found on the upperside of hindwings, which in 3 icaii<ddes (at least 

 in Californian specimens) shows a more or less distinct row of marginal 

 black spots lacking in pJwrea, for the most part entirely, or only very 

 faintly visible. 



Eviiis, Bdv., at present listed as a variety of pheres, I should be 

 inclined to remove from this association and place closer to icariaides : 

 if M. Oberthiir's figure of the $ be correct (I have no note on this), 

 then it probably will prove a good species ; the S very closely 

 resembles a small icarioidea ; the species was described from the 

 southern portion of California, and 1 have nothing before me that I 

 could definitely associate with this name. 



N<i)iiiade!> xercei^, Bdv. — Readily recognizable by the large white 

 nnpupilled spots on underside of both wings ; of late years Californian 

 collectors are disposed to regard this as merely a form of what has 

 generally gone by the name of antiacia, Bdv. (cf. Williams, Fhit. News, 

 xix., 476; Huguenin, Eut. Ncas, xxv., 826). I think this is correct, 

 only the name autiach must be changed to jiidi/p/ieiiiifs, Bdv., which 

 can best be characterised as .cerces with prominent black pupils to the 

 white spots of underside ; as Williams has stated, all kinds of inter- 

 grades between the two forms occur; )iiertila, Edw., is an aberration 

 of pol!/phe)nus in which on underside of forewings the discal dash is 

 joined to the base of wing by a v.'hite streak. Regarding antiacis, my 

 own opinion, from an examination of the type alongside the type of 

 polyphenuis, was that it was an aberrational form of this species, but in 

 spite of much material before me I fail to match M. Oberthiir's figure 

 exactly ; for the present therefore the name must remain doubtful. 



Concerning be/iri, Edw., Mr. Williams regards this as a good species 

 {loc. cit., p. 482) ; I have specimens of what is evidently Mr. Williams' 

 behri heiore me from San Fiancisco and concur with him that it is distinct 

 from polyii/u'iniis and more closely related to oro, Scudder, than any- 

 thing else ; there is, however, some doubt as to just what behri, Edw., 

 is ; the type specimens were received from Dr. Behr and may have been 

 returned to him ; my notes on the specimens at Pittsburg made several 

 years ago are as follows : " In Edwards' Coll. two <? s and two 9 s from 

 California labelled behrii in Edwards' handwriting. The ^s differ 

 from each other in depth of blue and breadth of marginal border ; the 

 underside shows traces of submarginal spots which would preclude 

 association with antiacis : the $ s look like the black-spotted form of 

 ocerces." 



A form of Mr. Williams' behri from Southern California with much 

 reduced spots on underside of hindwings has been commonly knovv^n as 

 pulijphetiuis by various Californian collectors ; this is an error as a 

 reference to M. Oberthiir's excellent figure at once shows.
