Psyche 
[December 
strongly capitate, never slender or smooth, rarely spicu- 
lately branched; longest hairs less than 0.15 mm. long; 
spiracles of abdominal segments II and in very far laterad, 
touching margin of tergal plates, sparsely surrounded by 
hairs and by papillae, the latter most numerous caudad of 
spiracle; three well-separated groups of hooklets near end 
of abdomen ventrally : - — a median ventro-caudal clump of 
about 30 hooklets on extreme end of last dorsal plate (terga 
IX-X?) and a pair of ventro-lateral clumps of about 23 
hooklets each, on anterior edge of last ventral plate (sterna 
VIII-X?). 
The combination of characters given above distinguishes 
the pupa of H. isolus from all Lycaenidae known to me. 
The pupa was held firmly to its substratum by a strong 
girdle.
