8 CIRCULAR 3 3 4, U. S. DEPARTMENT OF AGRICULTURE 



Color of head : Dull yellow. 



Epipharynx (fig. 4) : Apex obtusely pointed, with margins sinuous. Marginal 

 striae long and distinct. An oblique row of five vague striae near each 

 side of sensory eminence. The eminence has 2 pale sclerotized plates, an 

 arcuate row of 6 large sensillae, and an irregular group of dark fixed 

 teeth. Between and below the tormae are many sensillae and sensory hairs. 



Raster (fig. 6) : Two long nearly parallel rows of small, short spines. Out- 

 side of these,, numerous much longer, brown, hooked spines merging into 

 still longer, fine yellow hairs at sides and apex. The small paramedian 

 spines are not closely placed, and the two rows converge slightly toward 

 the anal end. 



Anal slit: Broadly Y-shaped. 



Vestiture: A few scattered long pale hairs throughout. Dorsal convexities 

 of first six abdominal segments with fine, pale, inconspicuous, evenly spaced 

 spines. 



Habitat : Soil under turf in pastures, lawns, etc. 



Remarks: Of the numerous PhyUopJiaga species, this and tristis are the only 

 ones that have been reared at Moorestown, N. J. 



PHYLLOPHAGA TRISTIS (Fab.) 



Length 25 mm. Form medium. 



Width of head 3.5 mm. 



Surface of head : Opaque, smooth. Epicranial stem a fine dark line impressed 

 in anterior half. Arms not conspicuous. Front with a distinct subcircular 

 impression at each side of middle near clypeal suture and two small punc- 

 tures below middle of epicranial arm. 



Color of head: Light brownish yellow. 



Epipharynx (fig. 4) : Similar to that of P. ephilida, but without submarginal 

 striae, with only one sclerotized plate (right) in sensory eminence, and 

 fewer sensillae on epigusta. 



Raster (fig. 6) : Two well-separated, arcuate rows of short brown spines. Out- 

 side of these a few longer, scattered, hooked spines. Sides of terminal 

 segment with sparse, rather long brown hairs, those of apex somewhat 

 shorter. 



Anal slit: A broad Y. 



Yestiture : Practically as in epliilida. 



Habitat : Soil under turf of lawns, pastures, and open grassy spots in wood- 

 land. 



Remarks : The two paramedian rows of spines of the raster resemble paren- 

 theses. These are distinctive. While the epipharynges of most Phi/llo- 

 phac/a grubs have submarginal striae, no trace of these could be detected 

 in the several tristis specimens available. 



POLYPHYLLA VARIOLOSA (Hentz) 



Length 40 mm. Form medium. 



Width of head 6 mm. 



Surface of head : Opaque because of fine reticulation. Anterior part of front, 

 more distinctly roughened. Epicranial stem impressed, the anterior third 

 with raised margins. Epicranial arms scarcely apparent. Three seta- 

 bearing punctures on each side of front. Clypeus and labrum rough. 



Color of head : Yellowish brown with two vague, longitudinal, lighter bands. 



Epipharynx (fig. 5) : To the right of the group of fixed spines on the sensory 

 eminence are a dozen or more small articulated spines. The right side of 

 the median bare area is bordered with numerous fine hairs. There are no 

 submarginal striae. 



Raster (fig. 7) : Numerous short hooked spines, with a short, distinct, double 

 row of short straight spines medially. Each side densely clothed with 

 longer brown hairs. 



Anal slit : Transverse, clearly sinuate. 



Vestiture : First five abdominal segments dorsally clothed rather densely and 

 evenly with short brown setae. Sides glabrous, venter with numerous 

 rather long brown hairs.
