Genus Euchloe, Hiibuer. 



Euchloe Coliagenes, sp. nov. PI. IV. figs. 4 & 5. 



5 . Alae supra sulphureo-fulvae : anticse margine apicali late brun- 

 nescente, a maculis fulvis interrupto ; basi cellse discoidalis pallida 

 grisescente ; puncto cellam termiuante uigro ; costa minime flavo- 

 ocliracea : posticse margine exteruo maculari fusco : corpus tho- 

 race ciuereo, pilis fulvis, capite colloque oclireo-flavescentibus ; 

 abdomine fulvo. 



Alae subtus fulvee : anticse pallidiores, fascia antemarginali lunulata ; 

 margine apicali ochreo tincto ; puncto cellulari velut supra nigro : 

 posticse ochracese, fascia tenui discali subobliqua angulari, apud

Hab. White Nile. B.M. 



This species is chiefly noticeable from its great resemblance 

 to the Hyale type of the genus Colias : it seems to belong to 

 the lone group of Euchloe. It would be very interesting if we 

 could get the male, to see whether it would have the violet tips 

 to the front wings, so characteristic of the lone type. 



Genus Taygetis, Hiibner. 

 Taygetis albinotata, sp. nov. PI. IV. figs. 6 & 7. 



c? • Alae supra olivaceo-fuscee : anticse integrae, maculis sex submar- 

 ginalibus pallidioribus : posticae margine externo sinuate, nigres- 

 cente; maculis quatuor punctoque subanali niveis : corpus fuscum. 



Alae subtus basi pallidiores ; fasciis tribus ocbreis pallidis ; interna 

 et media posticarum ad angulum ani coeuntibus, media latissima ; 

 externa nigro marginata, posticarum extus sinuata ; linea marginali 

 et margine ipso nigro-fuscis : antiose ocello uno subapicali niger- 

 rimo, albo pupillato et minime pallido ciucto : posticae ocellis sex 

 ochreo cinctis, primo et ultimo minoribus ; tertio et quarto sub- 

 reniformibus roseo-cinereis, lunulis albidis pupillatis ; aliis niger- 

 rimis puncto albo pupillatis ; ciliis niveis fusco variis : corpus 

 fuscum. 



Exp. alar. unc. 3g. 



Hab. Bolivia. B.M. 



This species is totally distinct from all the other species of the 

 genus ; and I have often been asked why I did not describe it. 

 I should have done so long since, but that I was anxious to give 

 a fisrure of the insect.
