end of the net. It was my first halesus, and by following pre- 

 cisely the same tactics I captured 46 specimens, almost all of 

 them fresh and perfect. 



The following year I went over the same ground, but did 

 not see one. In 1911 I was unfortunately just a week or so 

 too early for the flowering of graveolens and took only a few 

 scattered halesus. I believe that a little later I would have 

 found more of them. 



The larva of halesus is supposed to feed on mistletoe. I 

 noted a few clumps of it on some small oaks in the vicinity, 

 but none of the butterflies themselves were in close proximity 

 to these trees, 



Holland and Wright fail to bring out one point with refer- 

 ence to the sexes, namely, that the males have one small tail, 

 while the females have two one small, the other long, flat 

 and curled. The females are larger than the males and the 

 metallic green luster is confined more to the base of the wings 

 with more dead black on the outer areas. Denton's beauti- 

 fully illustrated book on butterflies mentions this difference 

 in the tail structure of the two sexes. 



T. leda. 



In October, 1911, I caught seven specimens at Silver Spring 

 below Goldroad at about 1500 feet elevation. I caught fre- 

 quent glimpses of these small, darting insects in the foliage of 

 the mesquite trees, but it was impossible to net them on ac- 

 count of the annoying thorns common on this tree. Finally I 

 found a clump of low flowering shrubs in a secluded corner 

 and had no difficulty in netting a small series while they were 

 feeding. 



A careful comparison of these specimens with an extensive 

 series of T. ines from Southern California, Southern Arizona 

 and Northern Mexico, in the possession of Mr. Fordyce Grin- 

 nel, Jr., and myself, show them to be exactly the same. As 

 Goldroad is only ninety miles west of Prescott, where the 

 types of leda were taken, this confirms us in the belief that 

 led a and incs are synonymous.
