The Female Larva— First Stage (Figure 13). — The newly hatched female larva (and 

 probably the male is identical with it at this stage of growth, since we have not been able 

 to separate them into males and females) is red in color, inclining somewhat to brown. 

 The body is ovoid in outline, being flatttened beneath and convex above. The antennae are 

 long and" six-jointed. Joint one is short and stout, and as broad as long; joints two, three, 

 four, and five, subcylindrical and subequal, much more slender than joint one, and twice 

 as long as broad ; joint six is as long as four and five together, and forms a long club, at 

 base equaling joint five in diameter, but broadening out to twice its width at tip. The 

 basal portion of the club is sometimes distinctly sejiarate from the rest, forming an addi- 

 tional joint. All joints have a few sparse hairs, and the club, in addition to several short 

 ones, bears near its tip four very long ones, each of which is considerably longer than the 

 whole antenna. The legs are thin and brown in color. The coxae and femora are moder- 

 ately large, while the tibiae and tarsi are long and thin, the terminal jciints of the latter

bearing several long hairs. The upper digitules are represented by simple hairs, but the 

 lower ones are present and are bent near the base. The eyes are prominent and are each 

 mounted on a short tubercle. The mentum is broad and apparently two-jointed. The 

 rostrum is broad at base and the rostral setae are not very long. At the tip of the rounded
