 vi present; a large red blotch around tubercles i aud 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. 



aS7(/£^c 111. — 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, O.G'"'". Body robust, slightly thickened at joint .5. more so at 

 joint 12; feet normal; pale green; a straight dorsal aud 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 aud 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 v,hite lines: anal plate blackish: thoracic feet blackish, 

 abdominal ones greenish. 



Htdf/r 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""". 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' tubei-cle 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. 



t^tage Y. — Head quadrate, rounded, slightly bilobed, shining light red-brown, 

 the clypeus high; ocelli and seta? black: width, 1.6 '""\ 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 .j, 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 

 M'hite dot below: subventral region of thorax blackish, of abdomen i)aler. white- 

 dotted. 



Stoffc VI. — Head roimded. qnadi'ate, 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 "'"'. Body 

 robust, cylindrical, tapering from joint .j to joint 2, the head small; joint .5 

 slightly, joint 12 distinctly, enlarged and abrujitly 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 

 n, the one on joint 12 uow scarcely larger than that on joint 11 ; upper half of 

 the lateral area grayer, with many white dots, lower half blacker, with few 

 dots ou 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 o, fading out at 

 6G — V
