 thorax black, the third segment of the antennae and the femur of each leg 

 dusky, the remaining segments of the antennae and the other parts of the 

 legs are greenish-yellow. Antennse about one-third the length of the body 

 and not on antennal tubercles. Spur very short. Third segment as long 

 as the fourth, fifth and sixth together, and with nine to ten transverse 

 rudimentary sensoria or elevations along the outer side. Fourth with four 

 to six, and the fifth with three to five toward the distal end. Forehead 

 slightly dished, body elongate, wings hyaline, with veins slender and 

 dusky. Fore wing with venation as in Schizoneura^ hind wing with one 

 oblique vein, which is sometimes forked. Nectaries are but pores, with a 

 slightly thickened edge. Cauda triangular and short. Body with a row

Measurements. — Length of body, 1.85 mm.; width, .94 mm.; length 

 of wing. 2.4 mm.; width, 1.88 mm.; total expansion, 4.6 mm.; antennal 

 segments, I, .056 mm.; II, .056 mm.; Ill, .-^i mm.; IV, .11 mm.; V, .084 

 mm.; VI, .07 mm.; spur, .014 mm. 



The pseudo-gall formed by this species is made on one edge of the

From a variation series of ten males and ten females which were 

 selected from more than twice this number of specimens, I feel confident

 of Thecla chrysalus. In many specimens the orange markings of the 

 upper side are completely wanting, and the ground colour of the under
