space above wliicli to near the costsil mari^iu wliich is lilaek at tlie liase, ami thence 

 rouud the bar to the inner margin is metallic blue ; beyond this crossing the cell 

 and extending from the costal to the inner margins is a broad white band ; the space 

 thence to the onter margin is black bordered on its inner edge by a metallic blue 

 line extending from the inner margin to the end of the cell, and crossed about its 

 middle by a broad band of metallic blue nearly straiglit on its onter edge, but 

 very irregular on its inner edge and widest in the middle, there is a rather broad 

 metallic blue band a little before tlie outer margin. 



Expanse of wings : liiuch. 



There is one specimen only of this very beautiful insect. 



190. Hypochrysops siren sp. nov. 



Male. — Uppersick : both wings brown black. Anterior wings with a patch 

 of iridescent bluish green below the cell, occupying the space between the lowest 

 median nervule at about half its length and the submedian nervure and thence 

 to the base with a streak of the same colour brlow the submedian nervure. 

 Posterior wings snlFused in certain lights with a patch of brilliant ]iur[ile which 

 extends over the cell, beyond it at its lower end halfway over the disc, and below 

 it nearly to the submedian nervure. 



Underside : anterior wings tawny brown ; the space in the cell is metallic 

 greenish gold with a broad ochreous baud running through it from the base and 

 extending beyond it above the upper discoidal nervule to a little distance from 

 the apex where it ceases, and is bordered outwardly with a narrow black line ; at 

 the eud of the cell the ochreous baud has a spur on each side forming an irregular 

 cross; the upper spur extends nearly to the costal margin which is broadly ochreous, 

 the lower spur crosses the end of the cell bordered on each side with black, below 

 which are two oclireous spots likewise bordered with l)lack and situate in the 

 angles between the median nervules at tlieir junction with the median nervure ; 

 there is a large patch of greenish gold at the onter side of the lower spur, above 

 the subcostal nervure is a broad streak of greenish gold followed by two greenish 

 gold spots above tlie nppcr discoidal nervule, the inner spot oblique, above these 

 spots are three smaller greenish gold spots situate between the third and fourth 

 subcostal nervules, on the disc about halfway between the discoidal and median 

 nervules are four contigaous ochreous lunules bordered on each side with black, the 

 outer margin is rather broadly pale ochreous, with five greenish gold spots on its inner 

 side crowned internally with black, and situate between the veins from near the ajjex 

 to the lowest median nervule. The jiosterior wings are crossed by four ochreous 

 bars bordered with black on each side, the space between the bars being greenish 

 gold, the lowest bar forms a loop commencing on the second subcostal nervule 

 where it touches the third bar, thence in a curve following the outline of the outer 

 margin to a little above the anal angle, the outer margin is ochreons with a row 

 of greenish gold sijots on its inner side, which are bordered on each side with 

 narrow black lines, a narrow black line between the two lowest median nervules, 

 which is situate inside the gold spot between those two veins ; there is a basal ochreous 

 streak on the costal margin. The outer margin is serrate, the tip of the veins black. 



Expanse of wings : 1 1 inch. 



Had. Gaui. 



One specimen only ; it is jirobably tlie most gorgeous of this beautiful genus.
