beetles, Crioceris asparagi Linn., and C. 12-punctata Linn., the 

 strawberry leaf-roller, Ancylis comptana Frohl., and the imported 

 cabbage worm, Pontia rapcB Linn., are all of European origin. 



The alfalfa weevil, Phytonomus murinus Fab,, is a native of 

 Europe, western Asia and northern Africa; the Mexican cotton 

 boll weevil, Anthonomus grandis, came from Central America and 

 Mexico, the sugar beet web-worm, Loxostege sticticalis Linn, from 

 Europe and northern Asia, the harlequin cabbage bug, Murgantia 

 histrionica Hahn., from Mexico and Central America, the Angumois 

 grain moth, Sitotroga cerealella Oliv. from Europe and the Argentine 

 ant, which has recently become such a pest in the Southern States, 

 from Argentina. 



Various other pests have also come to us from abroad, among 

 which are the elm leaf-beetle, GaleruceUa luteola Mull., the wood 

 leopard moth, Zeuzera pyrina Linn., the Hessian fly, Mayetiola 

 destructor Say., the hop plant-louse, Phorodon huntuli Schrank, the 

 willow and poplar curculio, Cryptorhynchus lapathi Linn., the apple 

 aphis, Aphis malt Fabr., the elm bark louse, Gossyparia ulmi Geoff., 

 the bed-bug, Acanthia lectularia Linn., the Buffalo carpet-beetle, 

 Anthrenus scrophularice Linn., the larder beetle, Dermestes lardarius 

 Linn., and the rice weevils, Calandra granaria Linn., and oryza Linn. 



The above list, while not by any means complete, will serve 

 to show the importance of introduced species. The injuries caused 

 by these imported pests are, of course, perfectly enormous, and, 

 running as they do irito millions of dollars, are beyond reasonable 

 calculation. 



While inspection service is doing considerable to prevent the 

 establishment of foreign insects, it is not by any means complete, 

 and, as has been suggested before, a federal law prohibiting the 

 importation of all nursery stock would be the nearest approach to 



perfection. 



A NEW MIDGE FROM GUATEMALA. 



BY T. D. A. COCKERELL, BOULDER, COLORADO. 



Hardly anything is known of the Chironomid fauna of the 

 highlands of Central America, but it cannot be doubted that these 

 regions are rich in species still awaiting discovery and descript'on. 

 When Mrs. Cockerell was in Guatemala City, although not specially 

 concerned with Diptera she obtained a couple of specimens of a 

 new form which is described herewith. 



October, 1915.
