some go upward a considerable distance also. The infested stalks are 
easily known by the tassel, and most of the top being entirely withered 
and white or yellow. Some stalks showed the work of more than one 
borer evidently, unless the same one had eaten out and then eaten in 
ip other places. in several stalks the live chrysalids of the borer were 
found near the bottom of their burrows, in the root, about even with 
the surface of the ground. [From these pup two of the moths were 
bred, issuing July 12. Sorghum grown near the infested corn on the 
college grounds could not be found infested by the borer. The same 
borers were sent to the college from Eddy, New Mexico, with report of 
much damage to corn. In many cases on the college farm the chrysa- 
lids were found dead and decaying in the burrows in the stalks. A dead 
larva was also found some distance above ground in a stalk. More 
dead pup than live ones were found, and probably this is the result 
of irrigation which makes it too damp for the pupz lodged in the roots 
and engenders disease. 
In discussing the paper Mr. Weed said that this insect damaged corn 
to some slight extent in Mississippi and considerably more so in Loui- 
siana. 
Mr. Howard said that this species is spreading northward rapidly 
through the Southern States and has reached the southern border of 
Maryland, but that it is not a pest to be feared with the methods of care- 
ful cultivation in vogue at the north. 
Another paper by Mr. Townsend was read by Mr. Marlatt: 
A NOTE ON THE WHITE GRUB OF ALLORAINA. 
By C. H. TYLER TOWNSEND, Las Cruces, N. Mex. 
On the 30th of April, 1891, I had a spot of ground on Judge Wood’s 
place, near Mesilla, dug into for white grubs. The particular spot dug 
into was selected because white grubs had been found in it before, al- 
though I was assured by Judge Wood that not a particle of vegetation, 
not even a weed, had grown on it for at least three years, and probably 
four. It was a bare spotin the back yard, and by digging over a square 
foot or two of ground 16 grubs were secured, at from 6 to 10 inches be- 
low the surface. These grubs were all about the same size, and appar- 
ently nearly full grown. The ground contained no roots of any kind, 
but their food habits in this barren soil were explained in this manner: 
They were left over night in a tin can in earth in which was also placed 
an elongate white larva about an inch and a half long that had been 
found in the earth at the same time with the grubs. The next morning 
nothing but the caudal extremity of this larva could be found; the 
white grubs had devoured it. If this carnivorous habit is known of 
Allorhina I am not aware of it. I know that some other Scarabaeid 
larva have been found occasionally carnivorous. But Allorhina I had 
‘supposed lived only on roots of grass or other plants.
