CHS attaclced by a fungus disease were observed September 25, 1909, on the 

 blossoms of a Eupatorium (probably perfoUatum) at Diamond Springs, Va. 



"The fungus seemed to attack first the abdomen of the adult, distending it 

 abnormally, and producing white, gi'eenish, or grayish rings of dense mycelial 

 growth on the thin membranous body-wall between the segments. Often 6 or 

 more beetles had attached themselves in their death struggle to a single small 

 head of flowers." 



There is said to be little doubt but that the fungus responsible for the death 

 of these beetles is identical with that described by R. Thaxter as Empusa 

 (Entomophthora) tampyridarum from diseased adults of C. pennsylvamcus 

 observed by him at Collowhee, N. C. " In June of the previous year a similar 

 epidemic of fungus among the related C. marginntus was observed, first by 

 the senior author, and afterwards independently by F. H. Chittenden, on the 

 experiment station farm at Norfolk, Ya." 



Attention is called to the fact that in the larval stage the food of the various 

 species of Chaulioguathus is composed of various small, soft-bodied insects, 

 largely aphids and other forms living near the ground. Since the usual great 

 abundance of these beetles no doubt acts as a check to the increase of several 

 species of injurious aphids, such as the pea aphis ( Macrosiphum pis/), the 2 

 species of Chaulioguathus mentioned are thought to be of distinct economic 

 value. 



The potato stalk borer, W. F. SIcSparran (Y. Y. Tribune Farmer, 10 {Wld), 

 No. 516, p. 18). — It is stated that in the potato district of Pennsj-lvania about 

 I'urniss injury by the potato stalk borer in 1911 amounted to thousands of dollars.

The orange-yellow coffee borer, Nitocris usambicus, H. Morstatt (Pflanser, 

 7 (1911), No. 5, j)p. 271-276, jil. 1, fig. i).— The author finds that in addition 

 to the white coffee borer, Anthores levconotvs, which is widely distributed in 

 South Africa and has for years been known to be a source of injury, a second 

 borer (N. usamMcus) is implicated in the injury to coffee trees. This paper 

 gives descriptions of its stages and accounts of its injury, life history so far 

 as known, and remedial measures.

 21, p. 247) includes descriptions of 15 species new to science.

 the influence of temperature, humidity, texture of food, etc, on the develop-
