There is no complaint in this country of injury to roots of alfalfa or 
grasses by white grubs, yet the adults swarm in the summer and de- 
Stroy much fruit, and the ground is full of their grubs. 
Ten of the above grubs were placed in a jar of earth to breed. On 
July 24, 1891, two imagos of A. nittda were found in the jar on the sur- 
face of the earth. 
Mr. Alwood stated that he had bred a dipterous parasite from the 
adult of Allorhina nitida. 
Mr. Marlatt thought that this instance of Mr. Townsend’s was 
interesting, but that it proved no general habit. He considered that 
the ground was probably rich in vegetable matter so as to afford food 
for the white grubs. 
Mr. Smith thought that it would be interesting to know whet the 
other larva fed on. 
Mr. Popenoe expressed himself as surprised at the extreme south west- 
ern distribution of the species. 
Mr. Marlatt then read a third paper by Mr. Townsend : 
NOTES OF INTEREST. 
By C. H. TYLER TOWNSEND, Las Cruces, N. Mex. 
A specimen of the Colorado Potato-beetle (Doryphora 10-lineata) was 
taken July 12, 1891, on our common wild purple-flowered Solanwm here. 
It is the only pecomnce I have seen here. 
The Bean Epilachna is in full force on the college nin All stages, 
from eggs to adults, found lastof July. Some experiments in spraying 
with Paris green were tried. The results up to August 1 were nega- 
tive, neither the insects nor the plants being killed. The solutions were 
purposely made very weak. 
The latter part of July, 1891, the Bollworm (Heliothis Ale was 
found in nearly every ear of corn in a patch on the college farm. They 
were of all sizes and colors, and were accompanied almost invariably 
by large numbers of Coleopterous (Hlaterid ?) larve, which seemed to 
work entirely independently of the worms, and bored all through the 
ripening kernels, doing much destruction. 
A leaf-miner was found on the vine during pane 1891, but was not 
bred. It mines the substance from between the two ene of the leaf, 
and its gallery may be seen plainly, with its small grub at the terminus 
of it. 
On the 15th of June, 1891, I found a rather large number of adults 
of a Rose Chafer (Macrodactylus sp.) on the leaves of the vine in a vine- 
yard about a mile from this place. They had eaten the leaves very 
badly and were nearly all in coitu, but were found on only tox or three 
vines. They soon afterward all diese peancil
