the sun, they quickly seek cover from its hot rays and hide themselves 

 away under clods, in crevices in the ground or about the bases of the 

 plants, showing no inclination to take flight, but running rapidly. 



On June yth, a female was dissected, and eggs found in the ovaries. 

 These eggs were yellow in color, cylindrical, and estimated to be 

 about I mm. in length and about one-fifth as broad as long, with the 

 ends roundingly truncated. It has not yet been possible to observe 

 where the eggs are deposited, nor have I been able to learn where the 

 insect passes the larval and pupal stages. As it belongs to a group of 

 beetles which includes Paria, Fidia, Colaspis, Heteraspis and several 

 other genera, species of which are known to feed upon the roots of 

 plants, in the larval stage, it is fair to presume that the larvae of this 

 species are of subterranean habits also. 



On July 2ist, Mr. Newell again visited the same locality and found 

 a few beetles still feeding upon the corn plants, usually inside of the 

 unfolding leaves or on the tassels. The effects of their attacks upon 

 the corn plant is shown in Plate VII, Fig. 3, while the general effect 

 is illustrated in Plate VIII, Fig. i, from a photograph taken by Mr. 

 Newell on July 23d, showing the condition of a field at that date, the 

 standing corn being that from a second planting. In a corner of this 

 field was a small space where the second planting had not been at- 

 tacked, and this is illustrated in Plate VIII, Fig. 2, showing what the 

 condition of the entire field should have been, even after the first 

 planting had been destroyed by the Myochroi/s. Both in the fields 

 and in our breeding cages the beetles fed freely on corn, timothy and 

 crabgrass, Panicum pubescens, but very sparingly on bluegrass and 

 redtop, and it is doubtful if the beetles can survive on the latter two. 



October 24, 1900, I found a few beetles about asters and feeding 

 on young belated broom corn. April 12, 1901, Mr. Newell found 

 one adult among asters, showing that at least some of the insects win- 

 ter over in that stage. No material damage has been done in the lo- 

 cality the present year, up to July 15th. 



A species of larvae were found in great abundance about the roots 

 of two species of Aster, A. pilosus var. platyphyllus and A. hirsuti- 

 collis, (?) upon the roots of which they evidently subsist. Owing to 

 the fact these larvae were swept off in myriads by the ravages of Sporo- 

 trichum globulifcnim, I was only able to rear a single adult, which 

 Prof. C. H. Fernald thinks may prove to belong to a new species of 

 Tortricidfe. Early in November, 1900, I visited the locality and
