22 INSECTS INJURIOUS TO SUBTROPICAL FRUITS. 



THE SECOND-STAGE OR MATURE LARVA. 



(PI. V, fig. 2.) 



Length 1.0117 mm.; width of mesothorax 0.2718 mm. Body long and cylindrical, 

 the head and thorax considerably narrowed, and the abdomen gradually converging 

 to the end. Color of thorax and abdomen translucent white to orange-yellowish. 

 Contents of the alimentary tract showing through as a greenish mass extending from 

 the mesothorax to the fifth abdominal segment; the posterior half of segment 1 and all 

 of segments 2 and 3 of the abdomen bright red ; last segment of the abdomen also bright 

 red. Surface of the body covered with minute granules and with numerous short 

 setae which are black in color and swollen at the tips. Head 0.0906 mm. in length, 

 0.1559 mm. in width, front rounded and sides bulging considerably, constricted behind 

 the eyes to a distinct neck. Eyes made up of a few large facets, red, no ocelli present. 

 Antennae seven-segmented, about 0.3473 mm. long; segments 3 and 4 long, slender, 

 spindle-shaped, and annulated; 5 short, cylindrical; 6 longer than 5, slender, cylindri- 

 cal; 7 slightly longer than 6, very slender; near the distal end of each segment are a 

 number of setse. Pro thorax with the anterior margin considerably narrower than the 

 posterior, sides rounded, a pair of setse on each side, a pair on dorsum near anterior 

 margin, and another pair near posterior margin. Mesothorax and meta thorax with a 

 number of setae near sides and a pair of spiracles on the anterior mesothoracic angles. 

 Legs translucent white. Abdomen 0.6795 mm. in length, 0.3473 mm. in width, fusi- 

 form, no evidence of ovipositor in female larva, a pair of spiracles on the sides of seg- 

 ments 2 and 9; segments 9 and 10 about equal in length, 10 with four long, stout setae, 

 0.2265 mm. in length. Segments of abdomen bearing longitudinal rows of setae at 

 eides, just within outline, and two incomplete rows on the dorsum. 



THE YOUNG NYMPH OR PREPUPA. 



(PI. V. fig. 3.) 



Length 1.087 mm. ; width of mesothorax 0.2567 mm. Shape fusiform, similar to that 

 of the adult. Head length 0.1057 mm. ; width at the eyes 0.1812 mm. Head rounded 

 in front and on angles so that the sides bulge strongly, sides strongly converging to 

 posterior margin. Head translucent white, more or less blotched with orange; eyes 

 red or orange, not large; ocelli absent; a pair of setae behind the eyes, another pair 

 between the eyes, and a third pair back of pair 2 more widely separated. Antennae 

 7-8egmented, translucent white, except segment 1, which is orange, extending forward 

 about twice the length of the head; segment 1 cylindrical, broader than long; segment 2 

 -cylindrical, narrowed at distal end, about twice as long as 1 and not so broad; 3 about as 

 long as 2, more slender, base constricted; 4 shorter than 3, somewhat rounded and con- 

 stricted at the base; 5 as long as 3 and 4 together, slender cylindrical; 6 short cylindrical 

 and not as stout as 5; 7 cylindrical, longer than 6, and tapering at the tip; a few setae 

 present on the segments. Prothorax more than twice as wide as long; sides rounded, 

 with the posterior margin the widest; translucent white, marked with orange; three 

 ■setae on each side, that at posterior angle longest, and four setae in a transverse row 

 ■on the dorsum near the anterior margin. Mesothorax with prominent angles, trans- 

 lucent white, with some orange on the dorsum. Wing cases translucent white, dis- 

 tinct from each other; those of the fore-wing extending to the posterior edge of segment 

 2 of the abdomen, and those of the hind wings extending to beyond anterior edge of 

 ■segment 3. Legs translucent white to faint yellow, strong, with a number of white 

 ■setae. Al)domen fusiform like that of the adult, translucent white to yellowish orange, 

 with a bright red band on posterior half of segment 1 and on all of segments 2 and 3 

 (in some examples, dashes of red on side of 2 or segments following), last segment also 

 bright red. Abdomen with about six longitudinal rows of white setae increasing in 

 length toward the posterior end of the body. Length of the abdomen 0.6644 mm.; 

 width 0.2869 mm.
