300 CALIFORNIA ACADEMY OF SCIENCES [Proc. 4th Ser. 



Other rather worn examples were seen flying briskly about the 

 summit, and one or two fresh specimens were observed in 

 late March, 1906, on Tagus Cove Mountain, at an altitude of 

 3500 feet. At this locality, was found a species of Gnaphaliiim 

 which was without doubt the larval food-plant of huntera. 



4. Pyrameis caryae Hubner, Samml. ex. Schmett., I, 1806. 

 One flown example taken at Wreck Bay, Chatham Island, 



January, 1906. Does not differ from Calif ornian specimens. 

 Several species of UrticacecB and Malvaceae occur in the Gala- 

 pagos, and on one or more of these the larva must feed. 



LYCAENIDAE 



5. Cupido parrhasioides Wallengren (Lye. par.). Wein. 

 Ent. Mon. IV, p. 37, No. 15, 1860. Eug. Resa. p. 355 (1861). 



This pretty "blue" was described from specimens taken on 

 the voyage of the Swedish frigate "Eugenie," in 1852. 



Wallengren's description is as follows^ (p. 355) 10. Ly- 

 caena parrhasioides : 



"Alis ecanudatis, infra canescentibus lineis albis duplicatis subundulatis, 

 posticarum irregularibus ; posticis ocellis 3-4 analibus, nigris coeruleo- 

 foetis; oculis hirtis. 



Mas: Alis supra violaceo-caerulescentibus, posticis punctis 2-3 analibus 

 nigris, sub-obsoletis. 



Femina: Alis supra fuscis, ad basin plus minus coerulea-pulverulenti- 

 bus ; anticis macula discoidali fusca, obsoleta ; posticis punctis 4 analibus 

 nigris, antice coeruleo-limbatis. 



Patria: Puna mense Martii. Insula St. Joseph mense Aprilis; ins. 

 Galapagos mense Maji. 



L. parrhasio, God. affinis videtur; L. optileti magnitudine sequalis, sed 

 interdum L. also baud major. %Mas: Alas supra violaceo-coeruleae, mar- 

 gine exteriore tenuissime infuscato ; posticse puncta 2-3 analia nigra gerunt. 

 Alse omnes infra canescentes ; anticae per discum lineas subundulatas, 

 transversas 6 albas, per paria sitas, quarum par externum postice abbre- 

 viatum, gerunt; alse posticae etiam lineas ejusmodi ostendunt, sed par 

 intermedium saepissime bis interruptum, et externum tantum inter costas 

 2-6 locum tenet, et cum pari intermedio ad finem tam antice tarn postice 

 cohasrit. Ad basin alarum posticarum linea albo unica se prsebit. Ad 

 marginem exteriorem alarum omnium circuli oblongi et intra illos anguli 

 confluentes albi locum tenet. Circuli 3-4 alarum posticarum anales sunt in 

 medio nigri caeruleo-foeti, ocelliformes. A basi alarum anticarum usque 

 ad medium, prope marginem anticum, striga fusca, postice albo-marginata, 

 locum tenet. Interstitia inter lineas transversa alarum anticarum fundo 

 obscuriora. iFemina mari infra similis, supra fusca, et ad finem cellulae 

 alarum anticarum maculam transversam, fuscam, obsoletam gerit. Alae 

 ejus omnes sunt supra ad basin cseruleo-pubverulentes et posticae puncta 

 analia 4 nigra, antice caeruleo-limbata, gerunt."
