doing considerable damage to wheat at Wellington, Kans. These 
Jarve attack the wheat in a very unique manner for wireworms. 
They do not seem to attack the roots, but bore into the cavity of the 
wheat stem and feed on its inner wall. In some fields as many 
as one-eighth of 1 per cent of the wheat stems were infested. A 
large number of these larve were placed in a rearing cage on 
May 6, 1910, and on June 24 four adults were found in the cage. 
Mr. Kelly found the adult beetles of this species numerous on corn 
plants in the field from July 3 to August 23. Early in March, 1910, 
an adult of this species was found in a clump of grass (Andropogon 
scoparius). In 1911 Mr. Kelly succeeded in rearing an adult from 
a pupa collected among the roots of corn. This adult emerged on 
July 19. Mr. T. H. Parks, at that time with this office, found the 
beetles very numerous on young corn at Winfield, Kans., and Okla- 
homa City, Okla., in 
June, 1910, and Mr. 
R. A. Vickery, also of 
this office, found the 
beetles very numerous 
on corn at Browns- 
ville, Tex., in’ Jume.

Owing to the superficial resemblance of the larva of Drasterius 
to those of Cryptohypnus, the notes in the files of the Bureau of 
Entomology relative to these two genera are very unrelable. Web-

Middle Atlantic States and has also been collected in New England 
and the Mississippi Valley. All of the beetles in this genus are
