UvAROV (B. p.). Rice Grasshoppers of the Genus HieroglypJms and 

 their nearest Alhes. — FUill. Ent. Res., London, xiii, pt. 2, August 

 1922, pp. 225-241, 3 figs. 



This paper presents a critical study of all the kuown species of the 

 genus Hieroglyphiis. These grasshoppers are weU known in India as 

 serious pests of rice, sugar-cane, Sorghum and other crops, H. banian, F., 

 in particular being implicated. Keys are given to the three genera 

 belonging to the group under revision, and to the species contained in 

 them. 



The new species described are Hicroglyphodes assaniensis, gen. et sp. n., 

 from Assam, HieroglypJms africanus from Kamerun and the Sudan, and 

 H. banian var. elongata, n., from Bengal. Species that appear to 

 be of particular economic importance are Parahieroglyphits bilineatus, 

 BoL, which has been found in small numbers associated with H. banian 

 in rice-fields in India ; Hieroglyphiis concolor, Wlk., recorded as a pest 

 of crops in India ; H. annulicornis, Shir., said to be a pest of sugar-cane 

 in Formosa, and also recorded as damaging Carina indica, but not 

 apparently observed as a pest in India ; H. nigrorepletus , BoL, recorded 

 at various times as a pest of hce, Andropogon sorghum, Setaria italica and 

 maize ; H. banian, which attacks rice, sugar-cane. Sorghum, maize and 

 Setaria, as well as grasses; and H. oryzivorus, Carl, destructive to rice 

 and some other crops. 



BucKELL (E. R.). Grasshopper Situation in Nicola Valley. — Agric. JL, 

 Victoria, B.C., vii, no. 6, August 1922, pp. 130-131 & 136, 2 figs. 

 The worst grasshopper outbreak in the history of British Columbia 

 took place in 1922 in the Nicola Valley, and severe damage was done 

 to the ranges, grain and hay crops. An account is given of previous 

 outbreaks and of the life-history and habits of Camnula pellucida, 

 Scudder (clear- winged locust), the most injurious species throughout 

 the diy interior regions of British Columbia. At the present time the 

 ranges over almost the whole area have been very seriously damaged, 

 and the majority of the low winter ranges are entirely destroyed, while 

 the grain and hay crops have been ruined. If the fungus, Empusa grylli, 

 and such natural enemies as the red mite, Eutrombidium [Trombidium) 

 locustarum, Walsh, do not attack the swarms, there will be a further bad 

 outbreak, in the summer of 1923, and at present climatic conditions 

 have not favoured these controlling factors. Blister beetles are the only 

 natural enemies that have sho^^^l a marked increase. Remedial 

 measures are irrigation ditches and poison baits. In a cattle country 

 dry cattle manure appears to be an excellent substitute for bran, the 

 poison and salt water being mixed with it. Grasshopper catchers may 

 be successfully used to supplement poison bait [R.A.E., A, ix, 489]. 



Harned (R. W.) & SiMiTH (M. R.). Argentine Ant Control Campaigns 



in Mississippi. — Jl. Econ. Ent.. Geneva. N.Y., xv, no. 4, August 



1922, pp. 261-264. 



The organisation of the campaigns against the Argentine ant 



[Iridomyrmex humilis, Mayr] in Mississippi, where successful results 



were obtained with the use of Barber's poison [R.A.E., A, viii, 285], 



is described. 



Experience shows that the erachcation of this pest is quite possible, 

 and it is hoped that it will soon receive attention from the Federal 

 authorities in a similar manner to that given to the European corn- 

 borer [Pyrausta nubilalis, Hb.] and other pests.
