Neva 
Dolerus sp. No. 1.—Full-grown larve of form (1) were found by Mr. 
Lugger June 18, 1886, near Baltimore cutting off the heads of wheat. 
Larve apparently identical wlth these, but too badly decomposed for 
positive identification, were received May 31, 1887, from Mr. H. A. New- 
land, of Middletown, Del.,with the report that they were very injurious 
to wheat in that locality. Additional specimens in good condition and 
apparently full-fed were received from the same party June 4, 1887, and 
on June 10 still others were forwarded by C. F. Kreider, of Lebanon, 
Pa., who reported their doing considerable damage to wheat. 
Mr. Newland writes of them that they are seldom so damaging to 
wheat as this year (1887) and last. He says that they cut off the stalk 
about four inches below the head. They do not work very rapidly, but 
take about fifteen minutes to cut off a single head. Last year they de- 
stroyed in many fields from three to probably five bushels to the acre. 
No adults wers obtained. 
Dolerus arvensis Say. No. 2.—The larvee (form 2) which have been re- 
ferred to this species are only so placed provisionally. The difficulty 
of properly separating the larve into lots, referable to distinct species 
before any material for comparison has been obtained, will be readily 
apparent. Larvee evidently of different species were very commonly 
associated on the wheat or grasses and were placed together in breed- 
ing cages, so that the reference of particular larvee to adults can not be 
made with certainty. 
Larve (form 2) taken on timothy were received from Mr. Webster, 
June 14, 1884. These specimens were full grown, and an unsuccessful 
attempt was made to breed one of them. Again on May 28 and 29 of 
the year following additional larve in various stages of growth were 
sent by Mr. Webster. A quantity of these were saved in alcohol and the 
others were placed on growing wheat. March 22 of the following year 
a Specimen of D. arvensis was obtained from this material. The only 
doubt as to the correctness of the reference of these larve to arvensis 
comes from the fact that one of the larve is recorded to have possessed 
the characteristic markings of form 4, and it may have been from this 
specimen that the adult came. 
A single larva (form 2) was received June 18, 1886, from G. H. Cook, 
New Brunswick, N. J., who found it feeding on a wheat stalk, the ear 
of which it had cut off. 
Larve received in 1883 from Mr. J. C. Hostetter, Minerva, Ohio, and 
mentioned in Bulletin No. 4 of the Division of Entomology, are in poor 
condition, but probably belong to this form. The attempt to rear these 
larve failed. The same larve were reported at about the same time 
by W.S. Chamberlain, secretary of the State Board of Agriculture, as 
occurring on wheat at Columbus, Ohio. Mr. Hostetter’s letters are in- 
teresting in this connection and may be quoted in full: 
I have as fine a field of wheat as I have seen this season. This morning, in look- 
ing over it, I find upon the heads quite a number of such worms as are here inclosed.
