m. m., on tlie inner margin 3.5 m. m. — thus forming a broad triangle resting on 

 the inner margin. The seventh line formed of lunules and not quite touching 

 the costa, which from it to the Base is brown. The eighth line is reduced to 

 a long lunule parallel to the costa. The base and disc of the posterior wings 

 covered with brown spots and lines of various shapes ; a submarginal band of 

 united lunules, surmounting a marginal series of six spots, situated between 

 the nervules ; the two anal spots are deep black, each surrounded by a ring of 

 chrome yellow ; the second of these spots is the largest ; they both contain a 

 lunule of metallic blue nearest the outer margin, and have also detached 

 scales of the same color scattered over them. 



2 . — Anterior wings above, white, with a very broad black border extended 

 from the base along the costa to the apex, where it is much thickened, and 

 from the apex to the inner angle, as in L. neglecta 2 . The base of the wing 

 and three bands corresponding to the principal ones below, are suffused with a 

 metallic blue reflection; the middle band extends from the black costal border 

 across the disc to the inner margin ; the outer band is an arm from the sub- 

 marginal black border, and is only suffused with blue internally ; posterior 

 wings with a blue reflection at the base; a black border formed of the sub- 

 marginal lunules and spots, which are united at the costal angle, but separate 

 towards the anal angle ; the two black spots beneath, particularly the second, 

 are reproduced conspicuously above ; beneath the markings are the same as in 

 the male, except that they are lighter, and in the posterior wings the discal 

 bands are only represented by a few isolated spots. 



Hah., Key West, Florida. Taken from Feb. 1 to 10. Types in 

 collections of Edward Burgess and H. K. Morrison. 



This species is the representative in our fauna of the Central and 

 S. American cassius, and will perhaps ultimately be considered 

 distinct from it. But in the large series of specimens which I 

 examined from diflFerent localities, I was nnable to find any constant 

 specific characters separating the two, although the Florida form 

 could readily be recognized by its general appearance. 



Tliecla niodesta. 



Lycaena modesta, Maynard, Amer. Xat., Vol. 7, March, 1873, p. 177. 



This species is not a Lycaena but a Thecla, belonging to a group 

 which has not until now been found within the limits of the United 

 States. Modesta is extremely close to, if not identical with, an 

 undescribed species which I have from Jamaica and Cuba. 



The insect fauna of Key West is tro]Hcal in its character, and 

 intimately connected w^tli that of the West Indies, while it differs 

 entirely from that of Florida, the nearest main land.
