juneip. i9i6 Aleyrodidae 465 



is dentate, the teeth large and bluntly rounded (fig. 2, D). The inner spaces are not 

 acute, but often squarely truncate. A space of 0.1 mm. is occupied by six or seven 

 teeth. On this feature alone the case is easily separable from those of the other species. 

 At the base of the teeth, forming a ring around the case, is a series of minute, clear, 

 porelike areas. On the leaf the case is jet black with the dorsum somewhat arched 

 and the abdominal segments marked, but not distinctly separated. On the margin 

 all around is a narrow cottony lateral wax fringe. This sometimes extends mesad, 

 irregularly covering the submarginal area, but dorsal secretion is usually absent. 



Adult female. — Length from vertex to tip of ovipositor, 1.12 mm.; color brovm, 

 under the microscope a deep wine color with darker shadings on head, thorax, and 

 tip of abdomen. The specimens at hand are somewhat imperfect and it is difficult 

 to make out the structure. The vertex seems to be rounded and possessed of a slight 

 median ridge. The eyes are very dark brown. The antennae are absent from the 

 specimens at hand. Labium yellowish, tipped with black. Legs yellowish, shaded 

 on femora with dusky. The femora and tibise of the hind legs are considerably darker 

 than the others; length of hind femora 0.288 mm.; hind tibiae 0.432 mm. The tarsi 

 have the proximal segment o.i mm. and the distal 0.06 mm. The proximal segment 

 is armed on its distal extremity with one large spine and several smaller ones; the 

 foot is normal, with the paronychium straight and hairy. Theforewings (figs. 2, F, G) 

 are 1.268 mm. long and 0.76 mm. wide at the widest part. The radial sector is heavy, 

 yellowish brown in color, and much curved. The cubitus is very fine, long and 

 slightly ciu^ed, that portion of the wing below it forming a more or less distinct lobe. 

 In color the wing is a deep smoky, excepting as follows: A line following the cubitus, 

 and a rather large spot near its distal extremity are colorless. A line following the 

 radial sector from its distal extremity to almost its median curve, and another crossing 

 it almost at right angles are colorless. This gives the appearance of a white cross on 

 a dark backgrotind. In some wings the marking is not so evident, but there is one 

 curved colorless line angling across the wing a short distance above and parallel with 

 the radial sector. The border of this white line seems more heavily shaded than the 

 remainder of the wing. The margin of the wing (fig. 2, //) is armed with a series of 

 rather prominent teeth directed toward the distal extremity of the wing. Each one 

 of these is armed with one prominent spine and usually three smaller ones. The 

 margin formed by these teeth and a line along their bases is bright wine red. The 

 hind wing is uniform smoky, with the vein yellowish brown. 



Adult male. — Much smaller than the female, measioring only about 0.79 mm. 

 from vertex to tip of claspers. The specimens are in poor condition, the antennae 

 are absent, and it is impossible to make out the structure with certainty. The color 

 is a yellowish or a reddish brown. The hind femora, 0.24 mm. and the hind tibia, 0.4 

 mm. in length. They are marked as in the female. The claspers (fig. 2, J) are 0.126 

 mm. long. Near their distal ends there are a number of jagged teeth and they are armed 

 with a number of long slightly ciu-ved hairs, those near the tip being the longest. 

 The penis is as long as the claspers, yellowish, and almost straight. 



Described from females, males, and pupa cases in balsam mounts and pupa cases 

 and eggs on the leaves.
