thrips. The former species occurs in widely separated regions in 

 Europe and is probably generally present over the entire region. 



T. minutissima L., present in England, Germany and Bohemia, is 

 another general feeder like flava and has about the same distribu- 

 tion. Thrips sacchari Krueger with T. serrata Kobus attacks sugar 

 cane in Java. Stentothrips gramineum Uzel is injurious to barley 

 and other grains in Bohemia, while Drepanothrips reuteri Uzel is 

 injurious to grape foliage in Sicily, especially to certain American 

 varieties (Riparia) . Phloeothrips olece Costa is one of the important 

 olive pests in portions of Europe, injuring the fruit and foliage. 

 P. pallicornis injures sugar cane in Formosa. 



It is apparent that our knowledge of the injurious Thysanoptera 

 is confined mostly to Holarctic forms. It is quite certain that other 

 regions will furnish many species which, -in their present or new 

 environment, will be quite troublesome. 



HEMIPTERA. 



Species of the order Hemiptera are of especial interest to crop 

 producers, for the sum total of losses for which they are responsible, 

 would amount to no small part of that chargeable to insects as a 

 class. 



HETEROPTERA. 



Pentatomidce. 



Two species of the genus Eurydema, namely, ornatum L. and oler- 

 acea L. are pests of cruciferous plants in Europe, and much resemble in 

 habits and general appearance our harlequin bug. The former 

 species occurs over most of Europe, Asia Minor, parts of Russia, 

 Turkestan, etc. The latter is even more widely distributed and is 

 recorded from all of Europe, Western Russia, Turkestan and Siberia. 



Several species, assigned to this family, are important in Aus- 

 tralia, as Stilida indecora and Rhoecocoris sulciventris, which, both 

 in the immature and adult stages swarm over orange orchards, suck- 

 ing sap from branches, causing the fruit to fall. Biprorulus bibax 

 is also an orange pest and is known as the spined orange bug. 

 Philia basalts is one of the common fruit bugs of North Queens- 

 land, and the so-called cherry bug, Peltophora pedicillata ranges 

 from New South Wales to North Queensland. A similar species, 

 P. picta Germ, also punctures cherries, causing the fruit to fall. 

 In South Africa, Bagrada hilaris, the Bagrada bug, injures crucif- 

 erous plants like our Murgantia histrionica Hahn. This insect 

 occurs over central Africa, Algeria and the Arabian Desert. Bag- 

 rada picta Fabr. also infests cruciferous plants in India. Plantia 

 affinis Dallas infests growing rice in New South Wales.
