tonj]^iie normal. The anterior leg of the male is stout, the femur some- 

 what widened in the male, and a little excavated inferiorly at the tip. 

 The tibia is stout and rather short, with the epiphysis as usual inserted 

 at about the middle. The har])es of the male are ('lon.i;<ited and rather 

 narrowed at the tip; the (*las])er is moderate in length, rather slight, 

 and not greatly curved.

Stage I. — Head scarcely bilobed, nearly white ; width, 0.05 mm. liody 

 white, rather opaiiue, the dorsum of Joints U, 4-5, 7-9, and lli broadly 

 pale ])urplish brown ; hairs black and white mixed. Warts with a 

 radiating crown and central hair, IV small with two setae, VI present, 

 elongate; several setae on the leg plate. 



Stage II. — Head white; width, 1 mm. Body as before or all white; 

 the warts large, the hair long and abundant, with a few stitt" black ones 

 the whole length, but more particularly on joints 5, 7, and 12. A few 

 secondary hairs. 



Stage Til. — Head creamy white, bilobed, with or without a vertical 

 line of spottings on the face of each lobe; width, 1.(5 mm. Body whit- 

 ish, scarcely touched with any brown marks, even in the most heavily 

 spotted examples of the previous stage. Warts large, concolorous, the 

 hairs long and soft, white, curving, some of them secondary. A black 

 pencil dorsally on joints 5, 7, and 12, or 5, 7, 8, and 12, or on 5, 7, 8, 9, 

 and 12. The larva sits in J-shape. The body is visible through the 

 hairs. 



Stage IV. — Head white or with a black mottled streak up each lobe, 

 full, rounded, scarcely bilobed; width, 2.6 mm. Body white, faintly 

 tinged with green.* Hairs very long, both jn-imary and secondary, tine,

 Another larva had a black pencil 5, 7, 8, and 12, with a black dot on 

 joint 9 to represent a fifth pencil. 



Stage V (interpolated). — In one instance this stage was observed; 

 in most larvae it was omitted. Structure and coloration as before.
