investigation. It was found that the species has been repeatedly introdiiced 

 on European nursery stock, and that it was already established in nurseries and 

 parks in some twenty localities scattered over nine States. Two native pines, 

 Pinus strohus and P. resinosa, are known to serve as food-plants, but so far no 

 case of an attack out in the forests has been recorded. There ai-e several members 

 of the genus Evetria indigenous to the U.S.A. closely allied to E. buoliana, 

 and, like it, confined to pines, and some of these are already recognised as 

 capable of doing considerable damage, bv^t although they pass throiigh two 

 generations in a year, none of them is so destrvictive as the newly introduced 

 species. The European pine-seedlings are imported in the colder months when 

 the young larvae lie dormant within the buds, so that an infestation is easily 

 overlooked ; in consequence of this, it is recommended that it wovild be advisable 

 to prohibit all importation of 2-leaved pines, even as the o-needled are already 

 excluded, for fear of introducing the destriictive blister-fungus, Peridermium 

 stroll, which has rendered it impossible to grow Weymouth Pine in Europe. 

 However, such extreme measures h'ave not been decided on, though it is urged 

 that this unwelcome visitor be stamped out before it spreads to the forests, and 

 while its extermination remains possible. The Bulletin is illustrated by a number 

 of excellent photographs and drawings.— H. G. Champion, Washington, D.C. :

Cumberland Hemiptera-Hetero2)tera. — Having, dviring the past two years 

 paid some attention to this Order, I give a few notes on the more interesting 

 of my captures, many of Avhich have been identified by Mr. E. A. Butler. 

 Picromerus hidens L., not uncommon at Orton, along with Elasmostethus 

 griseus L. and Scolopostethus decoratus Hahn ; Drymus sylvaticns F., var. ryei 

 D. and S., by sweeping at Stainton ; Gerris lacustris L, abundant on the ponds 

 at Cvimmersdale ; Ploiaria culiciformis De G., a single specimen on the wall of 

 my house ; Nabis ericetorum Scholtz, found in numbers on heather at Ortonj 

 with others of the genus ; Salda littoralis L., plentiful along the margin of 

 Lake UUswater, in company with 8. scotica Curt, and 8. c-album Fieb. At 

 Grinsdale I captured 8. cincta H.-S. and Anthocoris gallaruni-ulmi De G., rare 

 at Orton : all three species of Miris were common. Megaloceraea psammaecolor 

 Reut., was swept on the sandhills at Silloth, with abundance of Macrotylus 

 paykulli Pall. ; Bryocoris pieridis Fall., was locally common, and the same may 

 be said of Calocoris sexguttatus F. Of the rare C. alpestris Mey., I swept three 

 specimens in Gelt Woods. C. bipunctatus F., was not uncommon on sallow at 

 Orton and Combe Crags ; Plesiocoris rugicollis Fall., also on sallow at Combe 

 Crags on the River Irthing ; Lygus kalmii L., at Orton and Durdar on Umbelli- 

 ferae ; Dicyphus stachydis Reut., at Gelt and Shawk Quarries ; Cyllocoris 

 histrionicus L., this fragile creature occurred very sparingly at Caldbeck and 

 Combe Crags ; C.flavonotatus Boh., was not uncommon at Gelt, where Mecomma 

 amhulayis Fall., was plentiful ; Harpocera thoracica Fall., Sceughmire ; Phylus 

 coryli L., rare. Gelt. Five species of Psallus were found, but none abundantly : 

 these were P. betuleti Fall., P. varians, H.-S., and P. roseus P., from Orton, 

 P. ambiguus Fall., and P. variabilis Fall., from Gelt. Plagiognathus chrysaii-
