much damage in this way. Prof. Bruner writes that it does not quite 

 agree with Thomas's description. 

 Acridiuni shoshone, Thos. 



For a week or two during the first part of July, I noticed the mesquite 

 (F. jtiliflora) to be greatly infested with this large greenish locust, which 

 was so numerous as to almost defoliate some bushes. On July 14 many 

 nearly leafless bushes were seen, from which, on one's approach, would 

 fly swarms of these locusts. 

 Melanophis, sp. 



A number of specimens of our ordinary species of Melanoplus were 

 put in a breeding cage with earth June 28 and 29. On July 24 the cage 

 was full of young locusts. The old ones had been transferred to another 

 cage a couple of weeks before. No eggs were taken up with the earth 

 put in the cage, since this was dry sand which had been carefully looked 

 over. 

 Bootettix argentattis, Bruner. 



This locust was found in large numbers on Larrea mexicana July 17, 

 1 89 1, and on no other plant. It is of a beautiful rich green, variegated 

 with velvet-brown, black and silvery-white, and apparently lives only on 

 the Larrea on the mesas. Its colour assimilates well with the peculiar 

 green of the Larrea leaves. On May 13, 1892, I foimd on Larrea some 

 very small locusts of a general greenish colour, which I am quite sure 

 are the larvae of this species. The creosote bush is in all probability the 

 food-plant of this locust. Determined by Professor Bruner. 



Lepidoptera, 

 Synchloe crocaie, Edw. 



The red and black, more or less spiny caterpillars of this butterfly 

 were found, about June 5, on Helianthus, sp. They live in colonies. 

 The last of June they were not to be found. Again, on July 28, a good 

 number were found and transferred to a breeding-cage, in which they 

 pupated July 30, suspending themselves from the top of the cage inside 

 as chrysalides. A half dozen imagoes issued August 3. This butterfly 

 is, therefore, two-brooded, and very likely three-brooded. Determined 

 by Mr. W. H. Edwards. 

 Triptogon modest a, var. occidentalism H. Edw. 



A large, light green sphingid larva was found, August 29, on the 

 Cottonwood ( Fopulus /remontii). On being placed in jar it immediately 

 went into the earth. The imago of this species issued March 25 follow- 

 ing. Determined by Dr. J. B. Smith.
