There is no complaint ia this country of injury to roots of alfalfa or 

 grasses by white grubs, yet the adults swarm in the summer ami 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. nitida 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 vegeteible matter so as to afford food 

 for the white grubs. 



Mr. Smith thought that it would be interesting to know what the 

 other larva fed on. 



Mr. Popenoe expressed himself as surprised at the extreme southwest- 

 ern distribution of the species. 



Mr. Marlatt then read a third paper by Mr. Townsend : 



NOTES OF INTEREST. 



By C. H. Tyler Townsknd, Las Critces, N. Mex. 



A specimen of the Colorado Potato beetle [Doryphora lOlineata) was 

 taken July 12, 1891, on our common wild purple-flowered Solarium here. 

 It is the only specimen I have seen here. 



The Beau Epilachna is in full force on the college farm. All stages, 

 from eggs to adults, found last of 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 {HeliotJtis armigera) 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 (Elaterid?) larv.ne, 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 June, 1891, but was not 

 bred. It mines the substance from between the two skins of the leaf, 

 and its gallery maybe 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 two or three 

 vines. They soon afterward all disappeared.
