 Holland, Butterfly Book 349, pi. xlvii, ff. 27, 28, 1898. 

 Colorado and Arizona, June and July. 



2. PAMPHILA LASUS 

 PampMla lasus Edw., Papilio rv, 54, 1884. 



Described from Arizona. I do not know the species. 



3. PAMPHILA LICINU8 



PampMla licinus Edw., Trans. Am. Ent. Soe. in, 275, 1871. 

 I do not know this species. 



4. PAMPHILA METE A 



Hesperia metea Scud., Proe. Ess. Inst, in, 177, 1862. 



Scudder, Butt. New Eng. ii, 1650, 1889. 



Holland, Butterfly Book 348, pi. xlvii, ff. 33, 34, 1898. 



New Jersey, New York, Massachusetts, New Hampshire and Rhode Isl- 

 and; May and June. This species is readily distinguished by its dark 

 color, vague, whitish maculation and the tendency of the macular band on 

 the Under surface of the secondaries to be produced along the veins. The 

 spots making up this band are neither separate nor very bright as in the 

 other dark colored species. 



5. PAMPHILA MORRISONI 



PampMla morrisoni Edw., Field and Forest in, 116, 1878. 

 Hesperia morissoni Plotz, Stett. ent. Zeit. XLiv, 215, 1883. 

 Biol. Cent.-Am., Rhop. ii, 478, pi. 93, ff. 9, 10, 1900. 



Colorado, May. 



This is a small, bright species which is readily recognised by the elonga- 

 tion of the white mark in the cell of the secondaries below. 



6. PAMPHILA COLVMBIA 



PampMla Columbia Scud., Syst. Rev. 56, (77), 1872. 



PamphUa sylvanoides Scud., (not Boisd.) Mem. Bost. Soe. Nat. Hist. li, 



(3), 351, pi. X, f. 22 (type), pi. xi, pp. 15, 17, 1874. 

 PampMla California Wright, Butt. W. Coast 241, pi. xxxi, 423, 1905. 

 Thymelicus erynnioides Dyar, Jn. N. Y. Ent. Soe. XV, 50, 1907. 



California, April and October. 



All of the specimens in the Barnes collection have the band very even, 

 as mentioned in the key; in Wright's figure it appears to be somewhat re- 

 duced toward the anal angle, but the color of the under surface of the 

 secondary is characteristic.
