128 THE ENTOMOLOGIST. 



H. ScHOUTEDEN enumerates the root-inhabiting aphids of 

 Belgium and their relations with ants [10] . 



E. D. Ball describes the food-habits of some American 

 Aphrophora larvae [4] . The larvae of A. 4-notata are found on 

 various plants and shrubs ; those of A. parallela are recorded as 

 forming frothy masses (like the allied Cercopis [= Philanus] in 

 this and other countries) on the tips of pine twigs. The American 

 author notes that the larvae of A. jjermutata, a rocky mountain 

 species, were found, not on the twigs of pines, but down among 

 the roots, ten or fifteen in a clump, and supposes that the 

 "original pine-inhabiting species, finding themselves unable to 

 maintain their froth-masses in their exposed positions on pine- 

 branches in such a dry atmosphere, were compelled to seek 

 moister conditions, such as are afforded by the shade and con- 

 tact with the earth under these bushy plants." 



G. W. KiRKALDY has published [3] the part of his Rhynchotal 

 contribution to the ' Fauna Hawaiiensis ' dealing with Coccidae, 

 Cixiaria, and Heteroptera ; the Tetigoniidae, Asiracinae, and a 

 small portion of the Heteroptera being reserved for further study. 

 On p. 150 it is stated that the genus Alloeoeranum is represented 

 for the first time. In 1899, however, it was figured in the Biologia 

 Centr. Amer., Rhynch. Heter,, ii., pi. 12, f. 6; Kirkaldy's 

 doubtful admission of Cuba as a locality for A. bianmdipes 

 may now be confirmed, as Champion has taken it (p. 197) 

 in Panama, Bugaba, and records it from Dorei Island, New 

 Guinea, and Dr. Puton informs the present writer that it has 

 been taken in France. 



G. Breddin enumerates the Rhynchota and Siphunculata of 

 the Arctic Region [2] , including in this term the lands north of 

 ihe limits of the birch, fir, and larch trees. Among species of 

 wide distribution, and occurring also in Britain, may be men- 

 tioned Nysins thymi, Gerris odontogaster, Reduviolus Ihesigus 

 ( = Nobis jlavomarginatus) , Acanthia littoralis and saltatoria, Tera- 

 tocoris viridis, Agalliastes ivilkinsoni, &c. Lists are also given of 

 the Rhynchota of Iceland and the Faroes. In the former, 

 Breddin has overlooked the records by the writer of Corixa 

 carinata from Hagvelta, near Storvaldir, and of Acanthia littoralis 

 from Storvaldir (1899, Revue d'Entom., p. 95). 



E. P. Felt considers [8] the grapevine rootworm {Fidia 

 viticida, Walsh, a coleopteron of the Chrysomelidae) to be a much 

 more serious enemy of the vineyardist than the grapevine leaf- 

 hopper (Erythroneura vitis, Harris), for whilst the operations 

 of the latter are confined to the leaves, and the amount of damage 

 easily controlled, Fidia inflicts its most serious injuries under- 

 ground, and in a great many instances a vine is nearly ruined 

 before the trouble is noticed. "The secrecy of this insect's work, 

 and the fact that the grubs operate on the large roots, where a 

 small amount of girdling is fatal, constitute the most dangerous
