small knob bearing a pair of stout diverging spines. The dorsum is 
moderately rugose and sparsely punctate on the thorax and the first 
three abdominal segments ; the remaining segments are smooth and 
more shiny. Segments 4 — 7 have at their anterior margin, above, 
a row of large punctures, becoming blackish and very large and deep 
toward the median line. Segment 6 is sparsely punctate laterally; 
the anterior half of segment 7 laterally and segment 9 laterally and 
dorsally are moderately punctate; segment 7 ventrally and on the 
anterior half and segment 8 thruout are finely and rather densely 
punctulate; and 5 and 6 are grooved on the median ventral line, 
flattened below and angulated each side of this at the location of the 
false feet. 
Xylina antennata Walk. 
Our larv?e of this species taken on apple leaves were collected 
May 12 and 2^, except one which was found as late as July 7. One 
larva matured and entered the earth May 22, and another July 14. 
Unlike the preceding species, pupation does not usually take place 
in a few days after the larva enters the ground, but seems to occur 
irregularly thruout a considerable period, and is usually delayed 
until fall. Of five individuals found July 25 in cells in the ground 
under apple trees, four were still in the lar\'al stage, and one was a 
pupa. In our breeding-cages pupation took place August 19, 20 and 
31, and September 3 and 10. The pupal period averaged about 32 
days. The adults emerged August 17 (from a pupa found August 
i), September 16 and 19, and October 7 and 8. Another series of 
larvae, taken in a different year, gave 15 adults, emerging Septem- 
ber 16, 28, 29 and 30, October 9, 10, 14, 15 and 16; two appeared 
October 9, and four on the loth. None of this lot hibernated as 
pupae. Slingerland's dates of emergence of this species ranged from 
September 13 to October 6. The adults winter over, and may be 
captured in winter and early spring; very likely some may not 
emerge till spring. Tv^o of our pupae which did not transform at 
all were apparently alive and healthy in the early part of the winter, 
and probably adults would have emerged in spring if under normal 
conditions. Our dates of capture of adults are September 29, Oc- 
tober 31, December 14 and 18 (in fallen leaves), February 24, 
March 17, 21, 22, and April i. Slingerland lists dates from August 
4 to April 20, with two records for May without exact date. 
The pupa (Fig. 14) differs from that of Tccniocaiupa alia in the 
following minor details. It is impunctate and shining, and without 
any ventral grooves or angulations on segments 5 and 6 of the ab- 
domen, tho the anterior margin of each abdominal segment bears a 
narrow band of rather dense, fine punctures; the terminal knob is 
longitudinally wrinkled above, and bears two large spinous filaments
