300 ENTOMOLOGICAL NEWS. [Nov., '03 



flesh-color, with a slight grayish reflection on the dorsum ; head bright 

 shining yellow ; antennae distinctly seven-segmented ; the following areas 

 are shining black ocelli, antennae, a large spot covering the dorsum of 

 segment 2, a triangular spot below this on each side and another spot 

 still lower, a small crescentic spot at upper side of base of each leg, an 

 irregular line on each side between the head and prothoracic feet, a small 

 spot between the two anterior pairs of feet, linear spots on the venter as 

 in the previous instar, growing larger posteriorly, anal appendages, hinder 

 border, two spots on the side and the median depression with the spine 

 of the upper valve, together with a large quadrate spot notched anteriorly 

 on the lower valve of the cremaster ; sublateral fold distinctly yellow ; 

 tips of mandibles reddish brown. 



Third Larval Instar. Length, 13.1 mm. ; width of head, 1.12 mm. ; 

 same as in the second instar, with the following exceptions : distal por- 

 tions of antennal segments, legs and anal appendages more or less whitish ; 

 mandibles black at tips ; spot on dorsum of segment 2 more trapezoidal, 

 with its longest side posterior ; two black spots, instead of one, below the 

 triangular spot on the same segment, the anterior one much larger; a 

 black spot on segment 3 behind the posterior angles of the trapezoidal 

 spot and a trace of a spot lower down on the same segment ; in general 

 more nearly flesh-colored. 



Fourth Larval Instar. Length, 18 mm. ; width of head, 1.7 mm. ; 

 diameter of body, 2.75 mm. ; larva very fleshy ; pigment beneath skin 

 very pink, with steel-gray reflection on the dorsum ; head shining yellow, 

 clothed sparsely with white hairs ; ocelli black, showing under a lens a 

 white spot in the center; antennae 1.32 mm. long, tapering, basal seg- 

 ment large, short, second, third and hfth sub equal, fourth nearly one- 

 half the third in length, sixth and seventh together equal in length to the 

 third ; labrum, 1.02 wide ; maxillary palpi four-segmented, .26 mm. long ; 

 labial palpi three-segmented, .24 mm. long, short, stout, tapering evenly ; 

 segment 4 annulate ; the black markings on segments 2 and 3 have be- 

 come larger and seem to form a continuous chitinous shield over the 

 dorsum back of the head ; linear spots between the legs on the venter 

 interrupted by an indistinct whitish line which extends along the venter ; 

 a corresponding darker line extends along the dorsum, interrupted on 

 the second segment by the trapezoidal spot ; thoracic legs five-segmented, 

 1.34 mm. long, black, the distal portion of each segment whitish, as in 

 the preceding instar, and bearing a circlet of spines ; tubercles and sub- 

 ventral fold on segment 13 more pronounced, yellow ; anal appendages 

 now white in the middle, black at tip and base ; median black spot of 

 upper valve of cremaster absent, whole depression whitish ; the stout 

 spine rising from the center of this depression short and curved forwaid. 



After about six days in this instar, the larva begins to turn 

 greenish, becomes shorter, and finds its way to the ground, in
