New Species of Scale Insects. 391 



£ggs. — The eggs are purplish, elongate-oval in out- 

 line, about .22 mm. long and .15 mm. wide. 



Young.— The newly hatched larva (Plate XXXIV., Fig. 

 3) is .22 mm, long by .13 mm. wide, purplish, and of 

 the form shown in the illustration. Antennse prominent; 

 eyes blackish. The anal filaments are inconspicuous ex- 

 cept at base, and a little longer (.15 mm.) than the 

 body is wide. Segments more or less distinct, with a 

 row of dark spots along the lateral margin. 



Mature male. — There are two forms of males: a perfect 

 male with fully developed wings (Plate XXXIV,, Fig. 1) 

 and a pseudimago w-ith rudimentary wings (Plate 

 XXXIV., Fig. 2). In the former the wings are long, ex- 

 tending, when folded over the back, a little beyond 

 the tip of the style, and the poisers are well developed 

 (see Fig. 1); in the latter the wings are represented by 

 mere stubs, as shown in Fig. 2, and the poisers are 

 short and stout, lacking the terminal hook. Length 

 of body varies from .25 mm. to .35 mm. In other 

 respects the two forms present few characters that 

 differ, and are in agreement as follows : the color is red- 

 dish brown ; thoracic shield and band not distinct, 

 conforming in general color to that of the rest of the 

 body; the legs are stout and lighter in color than the 

 body; tarsi sparsely hairy (Fig. 1, c). Eyes prominent, 

 nearly black; antennae yellowish, sometimes pinkish, ten- 

 jointed, covered with stout transparent hairs (Fig. l.h). 

 Style about .20 mm. long, and of nearly the same color 

 as the legs. Segments of abdomen distinct. 



Mature female. —The body of the female is rough, 

 deeply lobed (Plate XXXIV., Fig. 4), reddish brown, with 

 the central portion somewhat purplish because of the 

 eggs within. The last segment is yellowish and presents 

 the following characters (Plate XXXIV., Fig. 5): 



There are five groups of spinnerets. The anterior 

 group contains 20 to 27; the anterior laterals, 18 to 

 28; and the posterior laterals, 20 to 25. There are
