ANOMALA ORIENTALIS WATERH. 

 (Introduced) 



Length 25 mm. Form medium. 



Width of head 3 mm. 



Surface of head: Shining, shallowly reticulated and with several brown setae. 

 Epicranial stem in anterior half a fine impressed line with raised edges. 

 Epicranial arms barely apparent. Front with two paramedian setose 

 punctures near clypeal suture. Two transversely placed setose punctures 

 below middle curve of epicranial arm. 



Color of head : Brownish yellow vaguely clouded with brown. 



Epipharynx (fig. 2) : A vague sclerotized plate on the right below apex of 

 labrum. Sensory eminence with a distinct, wide, arcuate, transverse, 

 sclerotized plate. In the curve of this, several sensillae and 3 or 4 large 

 fixed teeth. 



Raster (fig. 6) : Subanal convexity with scattered, coarse, rather long, hooked 

 spines. Below this two paramedian rows of very short stout spines, about 

 14 in each ; these rows parallel or slightly divergent at anal end. Outside 

 of these, on each side, two sparse irregular rows of hooked spines smaller 

 than those of subanal convexity. Sides and apex of terminal segment with 

 numerous, rather long, brown hairs. 



Anal slit : Transverse, slightly arcuate. 



Vestiture : Generally as in Popillia japonica, but short dorsal spines slightly 

 more conspicuous. 



Habitat : Soil of certain nurseries, lawns, and golf courses. 



Remarks: In Popillia japonica, Anomala* orientalis, A. binotata, Pachystethus 

 lucicola, and Strigodenna arbori-cola the epipharyngeal structures are simi- 

 lar ; the slight differences in the sensory eminence, tormae, and sensillae 

 shown in the drawings should be carefully noted. 



ANOMALA BINOTATA GYLL. 



Length 23 mm. Form as in Popillia japonica. 



Width of head 3.5 mm. 



Surface of head: As in A. orientalis, but distinctly and finely reticulate and 



frontal punctures less apparent. 

 Color of head : Pale dull yellow vaguely clouded with darker. 

 Epipharynx (fig. 2) : Apparently without sclerotized plate near apex of 



labrum. The transverse arcuate plate partly encircling the sensillae and 



four fixed teeth is very narrow. 

 Raster (fig. 6) : Similar to that of A. orientals, but the two paramedian rows 



of short spines always clearly divergent at anal end. 

 Anal slit: Transverse, arcuate. 

 "Vestiture : Generally as in Popillia japonica, but short dorsal spines slightly 



finer and closer. 

 Habitat : Sandy fields and lawns. 

 Remarks : The reticulate head capsule, the finer frontal punctures, and the 



definitely divergent lines of spines of the raster characterize this species. 



STRIGODERMA ARBORICOLA (Fab.) 



Length 23 mm. Form as in Popillia japonica. 



Width of head 3 mm. 



Surface of head : Shining, feebly and finely granulate. Epicranial stem very 

 feebly impressed. Frontal punctures 3 or 4 between clypeal suture and 

 curve of epicranial arm. Front without median impression. 



Color of head : Pale dull yellow. 



Epipharynx (fig. 2) : Generally similar to that of Anomala orlentalis, but 

 sclerotized plate on right of sensory eminence distinct and smaller. The 

 darkened area including the sensillae of sensory eminence less broad. 

 Apex of left tor ma longer. 



Raster (fig. 6) : Similar to that of Popillia japonica, but the two paramedian 

 rows of short spines more irregular, longer, and nearly parallel. 



Anal slit : Transverse, arcuate. 



Vestiture : In general as in Popillia japonica.
