costa, between this and the inner transverse band. On the secondaries the two 

 outer rows remain the same, having, however, but one large black spot, surmounted 

 by a very large pale orange-yellow lunule ; rarely there are traces of another yellow 

 spot interior to this ; the inner band is formed very irregularly, and presents very 

 much the appearance of a W ; discoidal bars and basal spots as in monica. Hab. : 

 California. In Coll. Tryon Reakirt (Reakirt). 



Underside markings of EvEres argiades and the allied species. — 

 The underside of E. argiades is bluish- or greyish-white; all the wings 

 with a slender black discoidal lunule ; the forewings with a straight 

 subterminal transverse row of seven shorts streaks with white edges, 

 and faintly marked marginal lunules ; the hindwings with a curved 

 submarginal row of white-ringed dots, the inmost one of the four 

 round the discoidal far up, and almost touching the latter ; those of 

 the marginal series near the tail edged with orange crescents and 

 sometimes centred with metallic scales ; two small basal and two 

 costal white-ringed dots. The dots of the allied E. alcetas are much 

 rounder and less lineated, and in the subterminal row on the forewing 

 the dots form a bent rather than a straight series, being curved 

 beneath as the row passes the middle of the wing, and then continued 

 on to the inner margin. Chapman gives (in litt.) the following tabu- 

 lation of the underside markings of the Everids : — 



1. Spot between nervures 2 and 3 of the hindwings (the 4th of the row of 

 four round discal cell) close to the discal line — argiades, alcetas, Jischeri. 



(a) Tail short — fischeri. 



(b) Tail longer, slender — 



(x) No orange spots ; spot between nervures 2 and 3 of forewings 



advanced inwards — alcetas. 

 {y) Orange lunules above the marginal dots near tail of hindwing ; 



spots on forewing nearly in line — argiades. 



2. Same spot moderately close — minimus. 



3. Same spot remote — dipora, parrhasius. 



(a) Spots black — dipora. 



(b) Spots pale — parrhasius. 



As a comparison between the underside markings of art/iades and 

 alcetas the following appears to hold good : — 

 Argiades — 



f Orange spots present on underside. 

 * Long, slender tail. 

 ft Row of spots beneath forewing in fairly regular alignment. 

 ** Row of spots on hindwings with spot 4 (between nervures 2 and 3) 

 close to discal line. 

 *** Spots black, more often elongated than rounded. 



Of these characters, those marked "*," «**," tt***^" arG constant; 

 while those marked " f " and " ft " distinguish artjiades from alcetas. 

 A few aberrations of art/iades in the character marked " f " sometimes 

 approach alcetas. In the character marked " ft " alcetas may approach 

 artjiades more often than argiades approaches alcetas. In either a 

 fairly intermediate position is rarely passed. 



Egglaying. — Zeller observes (Stett. Ent. Ztt/., x., pp. 177 et seq.) 

 that the species is common at Glogau ; that, when egglaying, the $ 

 flies slowly about the plants of Lotus corniculatus, seeking out the 

 youngest flower-buds, crawling over the plant selected, and, when the 

 desired bad is found, bending the abdomen well beneath the bud, fixing 

 the egg thereto almost immediately ; more rarely the egg is laid on 

 the upperside of the bud, or between the petals of an already-open 

 flower, or on a leaf. He states that he more often discovered the eggs
