point on each side; a transverse depression in the middle of same. 

 Anal opening small and located at the lowest fourth in the end 

 view. 



Length, 5.5 mm. ; diameter, 2.25 mm. 



30. FRONTINA ALETIAE Riley (RUeyeUa aletiae Riley). FRONTINA ARCmPPIVORA 

 Williston (Ypophaemyia malaeoaomae Townsend). 



The puparia of these two species are almost identical; small, 

 smooth, elliptical, dull, dark yellowish red. Spiracles slightly raised 

 above surface of pupa, reddish black, located slightly above longi- 

 tudinal axis, each having three serpentine slits. Button large, round, 

 and near center of spiracular plate. Anal opening directly on center. 



Length, 5.25 mm ; diameter, 2 mm. 



31. CLAUSICELLA TARSALIS CoqailleU (Phylacteropoda tarsalis Coqnillett). 



Very small; subshining, yellowish red. Caudal end decidedly 

 protuberant, smooth, dark red. On each side at the base of the 

 tubercle is a large, blackish tubercle; above are two smaller tuber- 

 cles, near the center ; spiracles located on the apex of this large pro- 

 tuberance widely separated. Each plate is blackish, somewhat leaf- 

 shaped, with five slits, each on a small ridge. Button large, round. 

 Protuberance below the longitudinal axis, the upper edge at the base 

 touching the axis line. Anal opening very small, some distance 

 below the tubercle. 



Length, 3 mm. ; diameter, 1.5 mm. 



32. TACHINOPHYTO TORTRICIS Coquillett (Tortriciophaga tortricis Coquillett). 



Small; yellowish red, decidedly tuberculate on the posterior end. 

 Spiracles very protuberant, nearly cylindrical, contiguous at the 

 base, widely divergent at apex, shining black, with a roughened, 

 granular band in the middle, located on top of a large tubercle the 

 height of which is about half its diameter. Spiracular plates on 

 top of the cylindrical protuberances. Each plate has five very 

 small, reddish slits, each on top of a faintly defined ridge. Button 

 large, round, fairly well defined, and near the center of the plate. 

 Anal opening very small, far below the spiracles. Spiracles lo- 

 cated far above the longitudinal axis. 



Length, 4 mm. ; diameter, 1.75 mm. 



33. STURMIA PILATEI Coquillett. 



Small; reddish yellow, subshining, and nearly straight on the 

 ventral surface. Just below the apex of the posterior end is a faint 

 depression, giving the posterior end a faint appearance of being a 

 large tubercle. Spiracles are subshining, black, and faintly reddish 

 in the center, widely separated, the space almost equal to the width 

 of one plate. Each plate has three yellow slits, each on a broad,
