the pale area towards the base is much more restricted aud less distinct, and the dark 

 marginal area is much narrower towards the anal angle. 



Underside: on the anterior wings the blue liand extends along the outer margin 

 nearly to the outer angle, the space beyond it being dull blackish grey, and the white 

 area on the disc is much more restricted. t)n the posterior wings the white band 

 across the wings is narrower. The blue band which crosses the disc is narrower, 

 and is broken u[) into conical spots, divided by the nervures, and centred with lilack 

 si)ot8, which are less elongate than in T. tvallacel; the colour of this band is deeper 

 and somewhat violaceous blue. 



Female. — Upper»lde: both wings more rounded than in T. ■W(dlacei , s\m] the 

 pale spaces much browner and more restricted ; tiie ciliae less conspicuously white. 



IJndm-side : resembles the male and differs from the female of T. wcdlacei in a 

 similar way, the white ai'ea on both wings being ver\' much more restricted. 



Expanse of wings, both sexes : 1^ inch. 



Ilab. One nude from Wandesi, and a long series from Humboldt Bay. 



The specimen from Wandesi is small, and on the underside of the anterior wings 

 the dark costal and outer-marginal band is narrower than in the other specimens. 



Ii23. Thysonotis celius Feld. 

 A good series of both sexes from iiiak and Humljohlt Bay. 



224. Thysonotis caesius sj). nov. 



Male. — Ujiperslde: both wings blue, as in T. cepheis Druce, but differs from 

 that species in being larger, the wings broader and itunuler, and the outer margins 

 more broadly black. 



Underside also resembles T. cepheis, but tlie metallic colouring is more golden 

 and extended. 



Expanse of wings : li inch. 



One specimen only. I have lately received both sexes of this species from 

 Stephausort. 'Yhe female is blacker than that sex of T. cepheis, and the pale area on 

 the anterior wings is narrower, and does not extend so far towards the outer margin. 



225. Thysonotis sperchius I'cld. 



8ix specimens, three of each sex. 



226. Lampides euchylas Hiilm. 



\ good series of both sexes from Korrido an<l liumlioldt Bay. 



227. Lampides allectus sp. nov. 



Male. — Uppcrside: both wings very bright azure blue, crossed from a little 

 below the cell of the anterior wings and before the middle of the posterior wings 

 to the inner margin by a pure white baud ; outer margins of anterior wings narrowly 

 and of posterior wings rather more broadly black, the latter rather irregularly black 

 on the inner edge. 



Underside: anterior wings blacker than in L. aleuas Feld., with the white 

 area more restricted, and the blue subinarginal spots and lines lirighter and more 

 developed. Posterior wings with the outer half from the middle of the costal to
