 bug) has been seriously damaging Araucarias ; P. citri is reported 

 as breeding in considerable abundance on a carob tree, and Apion 

 cubicolle as feeding on olives. Adults of Scudderia furcifera and 

 Schistocerca sp., were common on 10th November, in the Feather 

 River Canyon.

In this paper, descriptions of the following parasitic Hymenoptera 

 are given : — Hyposoter interjedus (Ophioninae) on Prodenia orni- 

 thogalli, Mississippi and Florida ; Nepeira benevola (Ophioninae) 

 on Eurytmis eurytheme, Utah ; and Aphaereta sarcophagae (Alysiinae) 

 on Sarcophaga kellyi, Kansas. 



Liodontomerus perplexcus, gen. et. sp. n. (Monodontomerinae) 

 and Trimeromicrus maculatus, gen. et. sp. n. (Pteromalinae) both 

 from lucerne seed-pods infested with BruchopJiagus funebris, Arizona ; 

 Anastatus semiflavidiis (Eupelminae) from eggs of Hermleuca oliviae, 

 New Mexico ; Eupteromalus sarcophagae (Pteromalinae) on S. kellyi, 

 Kansas ; Habrocytus medicaginis (Pteromalinae) from lucerne 

 seed-pods infested with B. funebris, California ; Euplectrus insuetus 

 (Elachertinae) on Lorema accius, Florida ; Diaidinus insularis 

 (Eulophinae) on Agromyza inaequalis, Porto Rico ; Ceratoneura pre- 

 tiosa (Tetrastichinae) reared from galls on Mimosa, Texas ;

Gryllotalpa gryllofalpa {vulgaris) is spreading to a great extent in 

 the abundantly watered rice-growing districts in Italy, owing to 

 favourable conditions and the lack of control. On ground previously 

 planted with rice, wheat, oats, rye and maize have been severely 

 attacked, the maize having sometimes to be resown. If rice is sown 

 in dry soil, it may also suffer in the same manner, and during the 

 periods when the water is let out from the rice-fields, the insects 

 come down from the banks and injure the growing rice, the banks 

 themselves being mined by their galleries. Ploughing is usually 

 carried out in spring and autumn, whereas summer ploughing would 

 aid control by interfering with breeding. The plough should be 

 followed by workers on the look-out for nests, which should be destroyed. 

 The mole-crickets also infest rice-fields laid down to grass, which, 

 when afterwards sown with wheat or maize, help to spread infest- 

 ation ; frequent ploughing of such lands before sowing is advisable. 

 When water is admitted into the fields, the mole-crickets abandon 

 the submerged portions and may be killed while retreating. The 

 banks should be dug over and the nests destroyed. Carbon bisulphide
