Genus Thecla 



It is very common in Central America and Mexico; is not 

 scarce in the hot parts of the Gulf States; and is even reported as 

 having been captured in southern Illinois. It also occurs in Ari- 

 zona and southern California. 



(4) Thecla m-album, Boisduval and Leconte, Plate XXIX, 

 Fig. 10, $ (The White-M Hair-streak). 



Butterfly.— Smaller than the preceding species; on the upper 

 side somewhat like it; but the iridescent color at the base of the 

 wings is blue, and not so green as in balesus. On the under 

 side the wings are quite differently marked. The fore wing is 

 crossed by a submarginal and a median line of white, shaded 

 with brown, the median line most distinct. This line is contin- 

 ued upon the hind wings, and near the anal angle is zigzagged, so as 

 to present the appearance of an inverted M. Near the outer angle 

 of the M-spot is a rounded crimson patch. The anal angle is deep 

 black, glossed with iridescent blue. Expanse, 1. 35-1. 45 inch. 



Early Stages.— All we know of this pretty species is based 

 upon the account and drawings of Abbot made in the last century. 

 We need better information. According to Abbot, the caterpillar 

 feeds on astragalus and different oaks. 



This species has been taken as far north as Jersey City and 

 Wisconsin, and ranges southward as far as Venezuela. Its cita- 

 del is found in the live-oak hummocks of the Gulf States and the 

 oak forests on the highlands cf Mexico and more southern 

 countries.

 9, under side (The Martial Hair-streak). 



Butterfly.— The insect figured in the plate, which may easily 

 be recognized by its under side, has been determined by Dr. 

 Skinner to be the above species. My specimens coming from 

 the Edwards collection are labeled Thecla acts, $ . They were 

 taken at Key West. A comparison with the under side of T. 

 acts (see Plate XXIX, Fig. 38) will reveal the great difference. 

 Expanse, 1.00 inch. 



Early Stages. — Unknown. 



Habitat, southern Florida and Cuba. 



(6) Thecla favonius, Abbot and Smith, Plate XXIX, Fig. 22,

Butterfly.— The wings are dusky-brown above, with a small 

 pale oval sex-mark in the male near the upper edge of the cell in
