1894.] Entomology. 87 
Prof. J. B. Smith describes ‘the new genus Tristyla with one spe- 
cies, and seven other new species of Noctuids collected by the Death 
Valley expedition. 
In reporting on a collection of ants from Lower California and 
Sonora, Mexico, M. Theo Pergande describes’ two new species of 
Camponotus and one each of Atta and Aphzenogoster, as well asa new 
variety of Pogonomyrex badius Ltr. 
Mr. Lawrence Bruner furnishes as his report as Entomologist to the 
Nebraska State Board of Agriculture a valuable discussion, covering 
more than one hundred pages, of the Insect Enemies of the Small 
Grains. The list includes 143 species distributed among the orders 
thus: Diptera, 24; Hymenoptera, 11; Lepidoptera, 22; Coleoptera, 
33; Hemiptera, 28; Thysanoptera, 2; Orthoptera, 18; Thysanura, 
3; Acarina, 2. 
The peculiar pocket like abdominal appendages of female moths of 
the family Acræidæ are believed by A. F. Rogenhofer to be used in 
copulation.® 
From recent studies of the pup of moths Dr. G. A. Chapman con- 
cludes’ that the Pterophoride are not closely related to the Pyralide 
or Alucitide. 
The discussion concerning the “ highest” order of insects has been 
recently continued in Science by Packard, Smith and Riley, all of 
whom favor the placing of the Hymenoptera above the Diptera. 
From recent anatomical studies, Krasilstschik concludes” that 
Phylloxera and Chermes should form the family Phylloxeride and 
should be regarded as more primitive than the Aphidide or Coccide. 
Dr. C. V. Riley’s report as entomologist to the U. S. Department of 
Agriculture for 1892 discusses recent international exchanges of bene- 
ficial insects, the importation of two dangerous insects—the potato 
tuber worm (Lita solanella Boisd.) and the Olive Pollinia (Pollinia 
coste Targ,)—the spread of the horn fly, the ox bot, the rose sawflies, 
the strawberry weevil, the elm leaf beetle and experiments with the 
European white grub fungus. In addition to these discussions there 
is a brief review of the work of the field agents of the division, and 
summarized accounts of the pea and bean weevils, the sugar-beet web 
worm (Loxostege sticticalis L.), the sugar-cane pin borer (Xyleborus 
perforans Woll.),and the new insectary of the department. .
