brown, the stripes dull yellow, arranged as in the next stage, the 

 subventral ones interrupted at the bases of the legs and correspond- 

 ingly on the legless segments. Cervical shield, anal plate, thoracic 

 and anal feet and the abdominal feet outwardly, black. A few short 

 pale hairs. 



Fourth Stage. — Head higher than wide, rounded, quite flat 

 in front, depressed a little at the sutures at the top of the triangular 

 plate and furnished with a few hairs. Color black, or blackish red 

 to light mahogany-red, or even orange tinted in different e.xamples 

 of the same brood, the eyes and jaws black, labium and antennae 

 yellowish, the latter black ringed. Body black, becoming brownish, 

 four lateral stripes, a subventral and ventral one pale yellow, the 

 lateral ones becoming almost white in some examples, all nearly as 

 wide as the intervening spaces. They run nearly to the anterior 

 edge of joint 2, except the first and second lateral, which stop at the 

 cervical shield and end before reaching the anal plate, except the 

 third lateral and the ventral. The subventral line is interrupted by 

 the light reddish bases of the legs and by reddish spots on the leg- 

 less segments, except on joint 13. Cervical shield, anal plates, 

 thoracic feet and the abdominal outwardly, shiny black; the anal 

 plates punctured and narrowly bordered withocher yellow. In 

 some examples with red heads this border is broader, and the cervical 

 shield is partly ochreolis-orange. Hair whitish, thin and short, 

 growing from minute black tubercles. 



Fifth Stage. — Head as high as wide, 'rounded, a little flattened 

 at the extreme front, depressed at the sutures at the top of the tri-

 color of a cherry stone. Labium and antennae paler, the latter with 

 two black rings; jaws black; eyes blackish. Body black, the stripes 

 pale yellow, the lateral ones in some examples becoming white and 

 in a few canary-yellow, narrower than the intervening spaces, con- 

 tinuous from cervical shield and the anterior edge of joint 2, except 

 the subventral, somewhat interrupted and irregular on joints 12 and 

 13, and barely reaching the anal plate, except the third lateral. 

 Cervical shield, anal plate and abdominal feet, except an outward 

 blackish band on the latter, concolorous with the head. Bases of 

 all the legs (except the anal) and corresponding spots on the legless 

 segments darker red. Thoracic and anal feet black. Hair thin, 

 about 5 mm. long, with some short, more numerous, fine black 

 hairs seen with a lens. At maturity the head is more of a brownish 

 red. Length about 50 mm.
