Genus PLATYLECANIUM Cockerell and Robinson 
Platylecanium asymmetricum sp. nov. Plate 1, fig. 7. 
Adult female.—Occurring on the under surface of the leaves 
of the host; length, 4 to 4.5 millimeters ; width, 1.5 to 2; elongate, 
narrowed at each end, flat, dark reddish brown, sometimes almost 
blackish in the dried specimens, with more or less black mottling, 
probably due to the drying of the internal organs; eye spots 
Pale, surrounded by a blackish area; all specimens prominently 
Symmetrical, with either the left or the right margin nearly 
Straight and the opposite side broadly rounded ; with slight inci- 
Sions opposite the spifacles; fading out to yellow or reddish 
brown when boiled in caustic potash, the discal area darker; 
Cleared derm showing numerous faint areolations, especially 
in the caudal region and dorsally pores of two sizes, the larger 
of these scattered over the surface, particularly near the margins 
and in about six irregular rows extending across the body be- 
tween the eyespots and the anal plates, the smaller pores occur- 
ring mostly in irregular groups on each side and cephalad of the
