LARVAE OF APHODIINAE — JERATH 65 



Epipharynx with protophoba bistichous on left and monostichous 

 on right; protophoba with 13-15 microsensillae. Tormae similar in 

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

 irregular; epitorma asymmetrical and flattened apically. 



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

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

 gitudinal row of 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. 



Annulets of abdominal segments 1-5 with setation as follows: each 

 prescutum with six short setae, each scutum with three or four short 

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

 with 10 short setae. Each abdominal spu-acle-bearing area with two 

 setae ventrally and one seta dorsally. Tenth abdominal segment 

 narrows considerably. 



Raster with teges of 26-32 hamate setae curved at theu- distal ends, 

 setae arranged more or less in rows with varying number of setae in 

 each row.

Material examined: Twelve thhd-stage larvae collected in cow 

 dung at Hyannis, Mass., June 27, 1939, by Wm. H. Anderson 

 (USNM) ; 35 third-stage larvae obtained by confining the adults with 

 fresh cow manure from Apr. 27 to May 26, 1944, at Lexington, Ky., 

 by Paul O. Ritcher (Nos. 44-70(1), 44-70(2), 44-70(3)). 



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

 1.22-1.45 mm. Oranium light yellow to light yellowish brown, sur- 

 face smooth except for two depressions on the frons on each side, two 

 or three dorsoepicranial setae and three or four microsensillae on 

 each side. First and second antennal segments subequal, third 

 shorter than first or second. 



Epipharynx with protophoba polystichous on left and monostichous 

 on right; protophoba with 15-17 microsensillae. Tormae similar in 

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

 small and irregular; epitorma asymmetrical. 



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

 teeth, none on palpifer. Galea ventrally with a long seta and a lon- 

 gitudinal row of 8-10 short setae, dorsally with five or six 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 prescutmn with six short setae, each scutum with two or three 

 long setae and three or four short setae on each side, and each scutel- 

 lum with eight short setae. Each abdominal spiracle-bearing area
