Habitat —Several hundred specimens of this variety have been exam- 
ined, all of which were collected in Mississippi by Prof. R. W. Harned or 
his assistants excepting the collections at Greenwood, which were made by 
Mr. J. M: Langston. The collection localities include Agricultural Col- 
lege, Kiln, Greenwood, Caesar, Ellisville, Forkville, and Starkville, Miss. ; 
the food plants of the beetle include poplar, elm, hickory, black oak, 
plum, apple, and pecan—the latter apparently preferred; and the dates 
of collection range from March 19 to June 4, April being the period 
of greatest abundance. 
PHYLLOPHAGA PEARLIAE, 0. Sp. 
This species belongs to the fusca group according to Horn’s synop- 
sis, but the genitalia are quite distinct from all recorded species. It has 
been designated in the writer’s determinations as new species “c”. 
The specimens before me are moderately shining, quite variable in 
color, ranging from reddish brown to almost piceous, the lighter colored 
specimens with the head and thorax darker. Clypeus densely, punctate, 
narrowly reflexed, moderately deeply and obtusely emarginate, front 
similarly punctate. Thorax moderately punctate, the punctures fairly 
uniform and distinct, noticeably narrowest at front, very slightly wider 
at base than at middle, margin plainly crenate but not conspicuously so. 
Elytra with punctures finer and more closely placed than on thorax, 
sutural coxae well marked, the others wanting or scarcely visible. Pygid- 
ium with punctures indistinct. Metasternum with hair moderately 
sparse and short. Claws arcuate, strongly and equally toothed at middle 
in both sexes. Length, 18 to 20 mm. 
Male.—Antenna 10-segmented, the antennal club as lowe as stem. 
Abdomen flattened at middle,\the penultimate segment depressed along 
the posterior border and with a slight but noticeable transverse ridge in 
front of the depression which is more abrupt at sides, the last segment 
concave in middle. Fixed spur of hind tibia short and stout, being 
alf, or less, the length of outer spur. The genitalia distinctive, claspers 
dissiniilar, the left being large, the right smaller and with a characteristic 
hook, as illusrated. (Pl. XLII, Fig. 12-15.) 
Female —Antennal club about half the length of the stem. Penul- 
timate ventral segment with a linear transverse impression near the 
posterior margin. The genitalia characteristic, and well illustrated in 
Figures 16 and 17, Plate XLII. 
This is a typical bottom-land species and was fairly common in the 
collections of Dr. Henry Fox in 1917 and of Fox and-Kisliuk in 1918 
in the Red River bottoms at Clarksville, Tenn. They collected it from 
April 29 to June 11 on elm (? American), winged elm, buttonwood, wil- 
low, and honey locust, by far the greater number being taken on honey 
locust. Mr. D. G. Tower collected a specimen of this species May 24, 
1915, under a log in a woods at Princeton, Ind., and the writer found a
