The experience of Comstock and Sifasetinnt was to the same gen: > 
eral effect, except that preparations for pupation did not begin with 
them until the latter part of May or the first of June. Adults had — 
emerged, however, from their pupal cells by June 27, in about six weeks 
after “the larve had been placed in their ‘breeding cages. With us, it 
will be noticed, preparations for pupation began April 20, the first 
pupx were found May 15 and 16, and the beetles appeared as early as 
May 25. The pupal stage was of ‘about three weeks duration. 
Description. Larva. (Plate VII, Fig. 3 and 4.)—‘Subcylindri- 
cal in form; considerably flattened; dorsum slightly more convex; and 
lateral fold prominent. Length, when full grown, 20 mm. to 25 mm. ~ 
Color dark waxy yellow; mandibles and cephalic margin of head black 
shading gradually into the dark brown color of the head. Head flatten- 
ed, and with long brown hairs arising from the pits on the sides. The 
cly peus with the “caudal portion fusiform, the cephalic part of this por- 
tion narrower than the caudal part: cephalic margin of clypeus with a 
large, prominent, three-toothed lobe on median line; the mesal tooth of 
this lobe is larger and longer than the others: on some specimens these 
teeth are more or less worn off. Labrum apparently wanting, being en- 
tirely within the cavity of the mouth. The mandibles are large, arcuate, 
and bear a short curved median tooth on the mesal side. The maxille 
have the cardo strongly bilobed; the stipes very slightly diminish in 
width toward the proximal end, which is truncate. The sides of the 
gula are nearly parallel, this part being but slightly narrowed towards 
its base; the base is rounded, with one long hair arising from a deep 
excavation near each lateral angle. Prothoracic segment subquadrate 
and nearly as long as the other two thoracic segments. The remaining 
segments of the body of nearly uniform length, slightly constricted at 
the sutures, and almost twice as wide as long. The caudal segment is 
considerably flattened, and has a large oval caudal notch formed by 
two rather long flattened projections, each of which curves slightly dor-_ 
sad and terminates in two short, blunt, horny diverging tubercles; the 
two inner tubercles project dorso-mesad, with a small hair-bearing 
tubercle arising from the lateral aspect; the outer tubercles project 
nearly directly ‘dorsad. The dorsum of the segment is bounded by a nar- 
row ridge which on the sides of the-segment bears four short, distinct, 
blunt, horny tubercles, the more caudal one being considerably larger. 
The area bounded by this ridge is convex cephalad, slightly roughened, 
bears no hairs, and is marked by a deep, roughened, linear depression 
on each side and a short mesal linear impression extending from the 
middle of the area to the caudal notch; ventral portion of the seg- 
ment slightly wrinkled; the semicircular fold around the anal proleg 
extends upon the base of the leg in the form of a thin finely striated 
margin; the distal margins of the joints of the leg are similarly striated — 
The prosternum is triangular, and acutely wedge-shaped caudad. The 
thoracic legs are short and stout.; each joint armed with short brown 
spines. Spiracles large, elongate oval, brown: there is a single thoracic 
pair situated on the second thoracic segment on the inflexed portion just 
in front of the coxe; there are eight abdominal pairs, each situated near 
the cephalic border of the segment. Surface of the body shining,
