56 SOME INSECTS INJURIOUS TO TEUCK CROPS. 
tubercles rather large, low-conical, black; leg shields slightly smoky; tubercle 
vi present; a large red blotch around tubercles i and iv on joints 5 and 12; 
setae short, black, stiff; traces of a white dorsal line showing especially by the 
cut between the red blotches at tubercle i of joint 5 ; no other lines. 
Stage III. — Head rounded, the vertex just within joint 3, pale reddish over 
the lobes and sides, luteous on the face, shining, very small in proportion to the 
body; width, 0.6 mm . Body robust, slightly thickened at joint 5, more so at 
joint 12 ; feet normal ; pale green ; a straight dorsal and a subdorsal white 
line and traces of a broken lateral one ; subventral region slightly pale, without 
defined line; tubercles small, black; a large, vinous, somewhat elevated blotch 
on tubercles i and iv on joint 5 and on tubercle i on joint 12, more diffusely 
about the spiracle on joints 11—12 ; anal feet reddish ; cervical shield small, 
infuscated, cut by three white lines ; anal plate blackish ; thoracic feet blackish, 
abdominal ones greenish. 
Stage IV. — Head rounded, rather quadrate, not notched, the clypeus high, 
vertex even with joint 2; pale red, paler on the clypeus, ocelli and antennae 
dark; width 1.0 mm . Body robust, thickened at joints 5 and 12, feet equal; 
blackish olivaceous, dorsal and subdorsal lines straight, yellowish white, edged 
with vinous dottings ; traces of a lateral line ; subventral region paler below 
the spiracles, especially after joint 5 ; large blackish-red blotches at tubercles 
i and iv on joint 5 and on joint 12 and tubercle i and stigma tally on joints 11-12 ; 
white dotting in the ground color most conspicuous stigmatally ; thoracic feet 
black, abdominal ones pale, anal pair reddish. 
Stage V. — Head quadrate, rounded, slightly bilobed, shining light red-brown, 
the clypeus high; ocelli and setae black; width, 1.6 mm . Body thickened at 
joints 5 and 12, feet equal, normal, the abdominal ones pale, slightly infuscated, 
the thoracic ones black-ringed ; dark gray to black, strigose-dotted with white ; 
dorsal line narrow, subdorsal broader, straight, even, yellowish white, centered 
with reddish mottlings, cutting the sooty-black cervical shield, but not the anal 
plate; a quadrate black patch between the lines on joint 5, a small angular one 
next the subdorsal line on all the other segments, large on joint 12 and shaded 
across; a narrow white-dotted lateral line, scarcely different from the dots of 
the ground color ; subventral band straight, yellow-white, broad, broken at joint 
5, reddish-filled around the spiracles, black spots at tubercles iii with a distinct 
white dot below ; subventral region of thorax blackish, of abdomen paler, white- 
dotted. 
Stage VI. — Head rounded, quadrate, about as high as wide, slightly bilobed, 
the vertex level with joint 2; clypeus high and large; red-brown, darker 
reticulate, mouth parts concolorous, ocelli black ; width 2.1 to 2.4 mm . Body 
robust, cylindrical, tapering from joint 5 to joint 2, the head small ; joint 5 
slightly, joint 12 distinctly, enlarged and abruptly tapered to joint 13; black, 
strigose-dotted with white ; cervical shield deep black, white-dotted, cut by three 
white lines ; anal plate similar, small, cut by the dorsal line only ; dorsal line 
narrow, black-dotted and broken, yellowish white, reddish on the centers of the 
segments; subdorsal line broader, straight, yellow-white, reddish centered on 
the segments, with a median row of gray dots, but not incised on the margins ; 
a row of segmental black triangles above it, free of white dots, largest on joint 
5, the one on joint 12 now scarcely larger than that on joint 11 ; upper half of 
the lateral area grayer, with many white dots, lower half blacker, with few 
dots on joints 5 to 13, separated by a row of brighter dots representing the 
lateral line ; on joints 2 to 5 this distinction is weakly developed ; spiracles in a 
blacker shade with a white dot above tubercle iv ; substigmatal band broad, 
even, undulate, weak and broadly gray, centered on joints 2 to 5, fading out at
