372 REPORT OF STATE BOARD OP HORTICULTURE. 



irregular transparent spots noted in the case of the female. The greatest 

 diameter in both sexes is less than one-half a millimeter, and in the charac- 

 teristics of the terminal segment both agree, practically, with the adult 

 female. 



Male pny-piqja — With the second molt the male assumes a form foreshad- 

 owing the true pupa, which may be called the pi^o-pupa.* The form is elon- 

 gate oval ; length five-tenths of a millimeter. The color is very pale yellow, 

 with the antennae, limbs, and wingpad, and two or three terminal segments 

 of the abdomen, colorless. The legs and antenna?, as noted, have reap- 

 peared, and also prominent pads foreshadowing the wings of adult. The 

 eyes are dark purple and placed close together. The antenna? are very stout 

 and curved closely around the edge of the body as far as the anterior legs, 

 where they bend inward. The wingi^ads are stout and almost entirely cover 

 the abdomen. The terminal segment is still broad and flattened and bears 

 two short spines, but the other characters have disappeared. 



True pupa of male — The true pupa resembles the previous stage, except 

 that the members are longer and slenderer, and the ]5rominent anal style 

 has appeared. The pupa is pale yellow and purplish in color, darkest 

 about the base of the abdomen, the head, antenna?, legs, wing sheaths, and 

 style being almost colorless and transparent. The eye sjDOts are dark purple. 

 The antenna? extend nearly to the middle femora, and are not curved under 

 the body as formei'ly, but are applied close to the sides, with the apex free. 

 The anterior legs are held forwai'd, reaching slightly beyond the eyes. The 

 middle femora rests transversely to the body, projecting somewhat beyond 

 the margin of the abdomen, while their tibia^ form with them a right angle, 

 and reach nearly to the apex of the hind femora. The latter incline poste- 

 riorly, while the hind tibite are applied close to the sides of the body, ex- 

 cept toward the tip, and reach nearly to the base of the style. The style is 

 rather stout, conical, obtusely jwinted at tip. and about as long as posterior 

 tibise. Length, eight tenths of a millimeter, including style, which measures 

 about fifteen-hundredths of a millimeter. 



Mature miale — The general color is orange with a faint duskiness on the 

 prothorax. The head is somewhat darker than 'the rest of the body. The 

 eyes are dark purple, almost black. The antenna? are yellow, somewhat ob- 

 scure or smoky. The legs and style are dusky, the latter paler than the 

 former. The thoracic shield is regularly ovoid, compressed anteriorly, dusky 

 in color, with margin brown, more distinctly so anteriorly ; transverse band 

 narrow, brown. Antenna? ten-jointed, two basal joints shortest, second 

 nearly globular, inserted in the first ; joints four and five subequal, longer 

 than any of the others: joint six next in length, and joints three, seven, and 

 nine shorter and subequal : joint ten still shorter, conical. Antennae some- 

 what hairy and nearly as long as the body of the insect. Wings, faintly 

 dusky, iridescent with yellow and green. Length of body about six-tenths 

 of a millimeter; style twenty-five one-hundredths of a millimeter. 



*The existenc^e of a pro-pupa or a first pupal stage in the Coccidpe analogous to the 

 tirist pupal stage fif higher Heniiptera has also been affirmed by Dr. Fr. Loew [Weiticr 

 JEiitom. Zcit., .Ian. 18iS4, p. \o).
