side. Second and third antennal segments subequal, first longer than 

 second or third. 



Epipharynx with protophoba bistichous on left and monostichous 

 on right; protophoba with 17-19 microsensillae. Tormae similar in 

 size and shape, both tormae produced cephalad and caudad. Crepide 

 irregular; epitorma asymmetrical, flattened apically, and little bent 

 towards laeophoba. 



Maxillary stridulatory area with an irregular row of 8-11 conical 

 teeth; none on palpifer. Galea ventrally with a long seta and a 

 longitudinal row of five short setae, dorsally with five setae. Lacinia 

 dorsally with a row of five long setae near the mesal edge and one 

 short seta posteriorly. 



Abdominal segments 1-5 each with three dorsal annulets; each 

 prescutum with six short setae, each scutum with two or three long 

 setae and three or four short setae on each side, and each scutellum 

 with 10 short setae. Each abdominal spiracle-bearing area with two 

 or three setae ventrally and one or two setae dorsally. 



Raster with teges of 34-47 setae arranged more or less in irregular 

 rows, with varying number of setae in each row; four minute setae 

 anterior to tegillar setae.

Material examined: Twelve third-stage larvae reared at Lexing- 

 ton, Ky., by Paul O. Ritcher (No. 44 7P(B)); 5 thu-d-stage larvae 

 reared at Lexington, Ky., June 20, 1945, by Paul O. Ritcher (No. 

 44-7P) (USNM). 



Description: Maximum width of head capsule of third-stage larva 

 0.89-0.96 mm. Cranium light yellow, surface smooth except for two 

 depressions on each side on the frons, two or three dorsoepicranial 

 setae and three or four microsensillae on each side. Third antennal 

 segment with a flattened sensory area apically. First antennal seg- 

 ment longer than second or third, second shorter than third. 



Epipharjmx with protophoba bistichous on left and monostichous 

 on right; protophoba with 16-18 microsensillae. Tormae similar in 

 size and shape, both tormae produced cephalad and caudad. Crepide 

 sub triangular ; epitorma asymmetrical and flattened apically. 



Maxillary stridulatory area with an irregular row of 7-9 conical 

 teeth; none on palpifer. Galea ventrally with a long seta and a 

 longitudinal row of seven or eight short setae, dorsally with five setae. 

 Lacinia dorsally with a row of five long setae near the mesal edge 

 and one short seta posteriorly. 



Dorsal annulets of abdominal segments 1-5 with setation as follows : 

 each prescutum with sLx short setae, each scutum with two or three
