SUGARCANE 
SUGARCANE BORER ( Diatraea sacrharalis Fab . ) 
Louisiana w. E. Hinds (June 24): The sugarcane "borer is just beginning 
the second generation at about the raiddle of June. This species 
is unusually scarce in both corn and cane this season, and a 
year of exceptional^ light infestation is anticipated. 
Trie hog ramma minutum Riley is not yet attacking the eggs. 
FOREST AND SHADE-TREE INSECTS 
PERIODICAL CICADA (Tibicina septemdecim L.) 
West 
Middle F. M. Wadley (June 17): Brood IV of the periodical cicada 
appeared this year in most woodlands throughout the eastern 
third of Kansas, in western Missouri, in some counties in 
southwestern Iowa, and in southeastern Nebraska, and in more 
localized areas in northeastern, central, and south-central 
Oklahoma, ani in extreme northern Texas. Scattering emergence 
occurred in southern and eastern Kansas beginning May 10; 
emergence was general May 20-30; and the adults were still 
active, ' ' though diminishing in numbers, June 17. A few 
complaints of oviposition in orchards were received from 
northeastern Kansas, but on the whole very 'little injury 
occurred. Nearly all the cicadas were of the dwarf form 
cassini . though some of the larger typical form occurred in 
places. 
SPRING- CANKER WORM ( Paleacrita vernata Peck) 
Pennsylvania T. L. Guyton (June 6): The presence of P. vernata was 
* noted in Erie, Crawford, and Mercer Counties. The caterpillars 
were quite small at that time (May 27). (June 27): P. vernata 
is quite numerous on soft maple trees in the mountainous 
districts of southern Sullivan County. 
Wisconsin E. L. Chambers (June 24): P. vernata is defoliating fruit 
and shade trees this summer over a large area extending from 
Madison to Green Bay and many trees are being killed in this 
area because of. repeated defoliation for the past ten years. 
North Dakota J. A. Munro (June 20): P. ve rnata has been very abundant 
over a large portion of the Red River Valley of the eastern 
part of the State and at Minot, Ward County. Observations 
indicated that upwards of 30 per cent of the worms were spring 
cankerworms and the remainder were mostly the lime tree spanworm, 
Erannis t iliaria Hr-rr. Most of the trees attacked have already 
been defoliated. Of the various trees attacked oaks appeared 
to be thu leest palatable to the worms.
