LYCAENIDAE. 



177. Hypochrysops polycletus Linn. 



A pair from Biak, which are tinged with purple on the underside of the 

 posterior wingrs, but otherwise are without any distinguishing feature. 



1"^. Hypochrysops rex Boisd. 

 A long series of both sexes from Mausinam, Ron, and Humboldt Bay. 



170. Hypochrysops apelles I"ul>r. 

 One specimen only from Dory ; it is larger than any of this species I have 

 seen, though there is a specimen in my collection from British New Guinea, and 

 another from the Island of Dorey, captured by Mr. AVallace, nearly as large. 



180. Hypochiysops plotinus sj). no v. 



Maz.e.- —U/jperside : both wings brilliant purple blue. Anterior winffs with the 

 costal area from the base as far as the costal nervure, ape.\,and outer margin broadly 

 brownish black, the black outer marginal area gradually tapering to the outer ano-le. 

 Posterior wings with the space between the subcostal nervnre and upper subcostal 

 nervnle to the costal margin dusky brown, with a narrow blue streak above the 

 former ; outer margin narrowly brownisli black, 



Um/erside : anterior wings pale ochraceous, rather darker at the lower part of the 

 cell and towards the apex and outer margin, crossed towards the apes from the costa 

 to near the outer angle by an oblique broad rufous brown band edged on each side 

 with a row of gold spots ; there is a submarginal row of gold spots between the veins 

 jiarallel with the outer margin, the spot near the apex the largest, gradually de- 

 creasing in size ; the four uppermost spots with black dots on the inner side, a 

 rather large gold spot in the cell near its upper end, and three gold spots between 

 the end of the cell and the rufous band. Posterior wings, basal fourtli pale 

 ochraceous, the rest of the wings rather darker, a streak on the costa at the base, a 

 broad longitudinal irregular bar from the base to a little liefore the apex almost 

 intersected in the middle, and joined at its middle by another bar which crosses the 

 cell from the inner margin at about one-fourth the distance from the base, across 

 the disc between the subcostal nervulcs is a ipuidraugnlar spot which is confluent 

 with a triangular spot between the second subcostal and the discoidal nervnle, the 

 latter being contiguous with the outer end of the bar wliich crosses the cell ; 

 rather nearer the margin are three confluent spots, the middle spot the longest ; 

 beyond which to the inner margin is another spot ; all the spots are bright rufous 

 and edged on each side with gold ; a narrow submarginal gold line traverses an 

 outer marginal broad band which is pale rufous. 



FEMAL^. — U/jpersit/c: both wings pale ochraceous ; anterior wings, with the costa 

 at one-fourth from the base, and thence extending very broadly over the apical and 

 outer marginal area dark brown ; the inner edge of the dark area irregular and 

 curving to the inner margin at three-fourths from the base ; posterior wings with 

 the space between the costal margin and the snl)C0stal uervure and subcostal 

 nervules dark Ijrown, the median nervules and submedian uervure are tijipetl with 

 brown a little before the outer marjciu, the brown colour extending inwards a little
