 No. 18, pp. 283, 284, fiff'"^- 2).— A brief summary of information on injurious 

 carabid beetles.

Sweet potato root weevil (Cylas formicarius), W. Newell {Quart. Bui. 

 Plant Bd. Fla., 2 {1911), No. 1, pp. 81-100, figs. 2).— A summary of information

 far north as Daytona, Volusia County. 



Shot-hole borer of tea [Xyleborus fomicatus], E. R. Speyeb {Dept. Agr. 

 Ceylon Leaflet k {1917), pp. 4, pi. 1). — A popular summary of information. 



Biology of the Tephrosia weevil, P. van deb Goot {Meded. Proefstat. Midden- 

 Java, No. 26 {1917), pp. 36, pis. 2, figs. 2). — An extended account of studies of 

 the coffee bean weevil {Araeocerus fasciculatus) , its parasitic enemies, and 

 control measures. This weevil is an important enemy of Tephrosia Candida in 

 Java. 



The toxicity of molds to the honeybee and the cause of bee paralysis, 

 G. TxJEESsoN {Svensk Bot. Tidskr., 11 {1917), No. 1, pp. i6-S8).— Investigations 

 of the cause of bee paralysis by the author led to the conclusion that it is due 

 to molds which infest poorly constructed hives. This contention has been 

 proved through feeding cultures of fungi, two of which species {Penicillium 

 sp. and P. stoloniferum) were obtained from the intestines of dead bees and 

 the others obtained from honeycombs. 



"Penicillium sp., P. stoloniferum, and Cladosporium herbarum seem to have 

 about the same degree of toxicity to bees and were all inferior in virulence 

 to P. conditaneum and Mucor. . . . The climate has undoubtedly something 

 to do with the different degrees of virulence in the molds, those of warmer 

 climates being far more toxic than those of temperate climates. This would 

 also explain why bee paralysis is much more prevalent and virulent in warm 

 than in cold climates." 



The injury is probably a phenol intoxication. " The symptoms of poison- 

 ing are on the whole the same irrespective of the mold employed in the 

 feeding experiments." The action is at first a stimulating one, followed by 

 paralysis and the death of the bees. Bees fed with pure honey as control 

 confirmed the finding from the mold material. 



The wintering of bees in Ontario, M. Pettit {Ontario Dept. Agr. Bui. 256 

 {1917), pp. 24, figs. 14). — A popular discussion of the subject in which it is 

 shown that if properly handled bees may be wintered successfully in any part 

 of Ontario either in cellars or outdoors.

Notes on Bombidae and on the life history of Bombus auricomus, T. H. 

 Fbison {Ann. Ent. Soc. Amer., 10 {1917), No. S, pp. 277-286, pis. 2).— The 

 studies of the life history and bionomics of B. auricomus, here reported, were 

 made in central Illinois, where the species does not occur very commonly. 

 The observations of the bumblebees supplement those of Sladen, previously 

 noted (E. S. R., 28, p. 562). The parasitism of a worker {B. auricomus) by a 

 mora, Rapides Parish, La., Is recorded.

 Econ. Ent., 10 {1917), No. 6, p. 56i).— The occurrence of Atta texana at Glen- 

 mora, Rapids Parish, La., is recorded.
