LARVAE OF APHODIINAE — JERATH 61 



Epipharynx with protophoba tristichous on left and bistichous on 

 right; protophoba with 18-22 microsensillae ; dexiophoba bistichous. 

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

 caudad. Crepide sub triangular; epitorma asymmetrical and elon- 

 gated. 



Maxillary stridulatory area with a row of 5-7 conical teeth; palpifer 

 with one or two teeth. Galea ventrally with a long seta and a longi- 

 tudinal row of 8-10 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 eight short setae, each scutum with three or four 

 long setae and five or six short setae on each side, and each scutellum 

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

 setae ventrally and one seta dorsally. 



Raster with teges of 41-60 setae curved at their distal ends, setae 

 scattered irregularly on the venter of 10th abdominal segment. 



Aphodius neotomae Fall 



Material examined: Six third-stage larvae reared by Paul O. 

 Ritcher (No. 46-lOD). 



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

 0.86-0.92 mm. Cranium fight yellow to light yeUowish brown, 

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

 the frons, three or four dorsoepicranial setae and three microsensillae 

 on each side. First and third antennal segments subequal, second 

 shorter than first or third. 



Epipharynx with protophoba monostichous, three or four small 

 processes on inside between dexiophoba and protophoba; protophoba 

 with 11-14 microsensillae. Tormae similar in size and shape, both 

 tormae produced cephalad and caudad. Crepide small and subcircu- 

 lar; epitorma asymmetrical and flattened apically. 



Maxillary stridulatory area with an irregular row of 6-10 conical 

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

 seta and a longitudinal row of nine short setae, dorsally with five 

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

 edge and a short seta posteriorly. 



Dorsal 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 long setae on each side, and each scutellum 

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

 setae ventrally and one seta dorsally. 



Raster with teges of 35-46 short setae scattered irregularly on the 

 venter of 10th abdominal segment. Lower anal lobe swollen into 

 two lobes, but not definitely divided.
