Material examined: Six third-stage larvae collected from hard 

 surface soil in horse pasture June 8, 1944, at Lexington, Ky., by Paul 

 O. Ritcher, No. 44-7B (FOR); two third-stage larvae collected at San 

 Benito, Tex., by M. P. Jones (USNM); six third-stage larvae, asso- 

 ciated with adults, collected in soil under cow dung at airport, Cor- 

 vallis, Oreg., June 9, 1955, by Manohar Jerath; seven third-stage 

 larvae and cast skins of five third-stage larvae reared to the adult

 by K. E. Frick and S. G. Cole (reared adults determined by O. L. 

 Cartwright) . 



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

 1.42-1.68 mm. Cranium light yellow to yellowish brown, surface 

 smooth except for three depressions in a vertical line on the frons on 

 each side, three or four dorsoepicranial setae and four or five micro- 

 sensillae on each side. Second and third antennal segments subequal, 

 first segment somewhat longer than second or third. 



Epipharynx with protophoba tristichous or bistichous on left and 

 monostichous on right; protophoba with 18-21 microsensillae. Tor- 

 mae similar in size and shape, both tormae produced cephalad and 

 caudad. Crepide subcircular; epitorma asymmetrical and bent 

 towards laeophoba. 



Maxillary stridulatory area with an irregular row of 7-10 conical 

 teeth; palpifer with one or two teeth. Galea ventrally with a long 

 seta and a longitudinal row of sLx or seven short setae, dorsally with 

 five setae. Lacinia dorsally with a row of six 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 eight short setae, each scutum with 3-5 short 

 setae and 2-4 long setae on each side, and each scutellum with 1 1 or 

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

 setae dorsally and two setae ventrally. 



Raster on each side with three short, longitudinal palidia, sur- 

 rounded on the sides by 24-35 tegillar setae. Raster with 14-23 

 caudomesally directed, spine-like pali. Tegillar setae arranged in 

 more or less regular rows, with varying number of setae in each row. 

 Four minute setae anterior to the other setae.
