DESCRIPTIONS OF AND NOTES ON SOME NORTH 

 AMERICAN LEPIDOPTERA. 



By Willlam Beutenmuller. 



Thecla ilavia, sp. nov. 



]\Li!c : Upperside brown, with a large fulvous patch beyond the middle of the 

 fore wings and a similar, but smaller, patch on the hind wing towards the anal angle. 

 Fringes whitish. Underside uniform, rather pale clay brown, giving the wings a 

 faded appearance. Across the fore wing is a broken darker brown transverse line, 

 edged with whitish outwardly. A similar line crosses the hind wings, but somewhat 

 darker, and forming a broken W above the anal angle. At the anal angle is a blue 

 scaled lunule, preceded and followed by a small orange spot marked with black. 

 Female, same as the male. Expanse, male, 24 mm.; female, 24-26 mm. 



Habitat : Texas (2 males and 2 females). 



Closely allied to Thecla aiitolycus, but differs from this species by 

 having only a single transverse line on the underside of both wings. 

 In aiitolyciis there are two sharply defined transverse lines on each 

 wing. It also differs by being very much paler on the underside, and 

 as the whole has a decided faded appearance. 



Sesia marica, sp. nov. 



Head black, palpi bright orange ; collar black, edged in front with orange. An- 

 tennie black. Thorax black, with a conspicuous orange stripe on each side, on the 

 patagia, meeting a transverse band on the posterior edge. Thorax beneath, with a 

 large cange patch on each side. Abdomen brown-black, with an orange band on 

 the posterior edge of the second, fourth, sixth and seventh segments. Middle and 

 hind femora brown-black ; tibia and tarsi orange, the former with a black band near 

 the end ; anterior coxi^ and femora brow^n-black inside, orange outside ; tibiae and 

 tarsi orange. Anal tuft black above, orange beneath. Fore wings transparent, 

 costal margin black, fringes brown ; inner margin orange. Basal transparent area 

 long, with the median vein black, continued as a violet streak to the hind angle. 

 Transverse mark orange red. Outer transverse area rather large, rounded, veins 

 black, orange between them at the outer part of wing. Hind wings with the costa 

 narrowly orange, outer margin very narrowly brown-black, fringes concolorous. Fore 

 wings beneath, washed with golden orange along the costa and inner margin to the 

 transverse mark, otherwise similar to the above. Hind wings beneath, same as above. 

 Expanse, 25 mm. 



Habitat : Punta Gorda, Florida. 



Type, Coll. Am. Mus. Nat. Hist. 



This elegant species may be readily known by the conspicuous 

 orange stripes and transverse band on the thorax, the orange red 

 transverse mark on the fore wings, and by the orange rays between
