Aphodius erraticus (Linnaeus) 



Figures 3, 29, 41, 85 



Material examined: Eight third-stage larvae collected in soil 

 beneath cow dung at College Park, Md., May 28, 1939, by W. H. 

 Anderson (reared adults determined by E. A. Chapin) (USNM). 



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

 2.27-2.40 mm. Cranium yellowish brown, surface smooth except for 

 three depressions in a line on each side on the frons. Clypeus with 

 a transverse broad protuberance in middle of anterior margin of its 

 sclerotized part, anterior angles of the latter raised into a tubercle. 

 Second and third antennal segments subequal, first longer than second 

 or third. 



Epipharynx tristichous on left and monostichous on right; proto- 

 phoba with 19-21 microsensillae. Tormae similar in size and shape, 

 both tormae produced cephalad and caudad. Crepide subquadrangu- 

 lar; epitorma asymmetrical. 



Maxillary stridulatory area with a row of 9-13 conical teeth; none 

 on palpifer. Galea, ventrally with a long seta and a longitudinal row 

 of eight or nine short setae, dorsally with six or seven setae. Lacinia 

 dorsally with a row of seven or eight long setae near the mesal edge 

 and two or three short setae posteriorly. 



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

 each prescutum with 10 short setae, each scutum with 4-6 long setae 

 and 11-15 short setae on each side, and each scutellum with 16 short 

 setae. Each abdominal spiracle-bearing area with two or three setae 

 dorsally and 4-6 setae ventralh^. Claw rather short, practically 

 cylindrical in basal half, spinules strong. 



Raster with teges of 52-75 short setae arranged in more or less 

 regular rows, with varying number of setae in each row. Four 

 minute setae anterior to the other setae. Lower anal lobe marked 

 into four sublobes, upper anal lobe horse-shoe-shaped.

Material examined: Six third-stage larvae obtained by confining 

 the adults with horse manure during May 1944, at Lexington, Ky., 

 by Paul O. Ritcher (No. 44-7D) ; two third-stage larvae obtained by 

 confining the adults with horse manure during April 1945, at Lexington, 

 Ky., by Paul O. Ritcher (No. 45-3A). 



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

 1.41-1.70 mm. Cranium light yellowish brown to yellowish brown, 

 surface smooth except for three depressions in a line on each side on 

 the frons, four dorsoepicranial setae and two microsensillae on each
