place where your specimen has been captured. One ought to let 

 them live, to see if they will multiply. It is a useful insect, de- 

 stroying the bed plant-insects and not at all noxious to vegetation. 



' ' The same sort of transport was effected from North Australia 

 to the hot-houses of Kew, England. The Cylindrodes, sort of 

 Gryllotalpa, was found in those hot-houses making great ravages 

 in the large herbaceous plants in which it makes canals and holes. 



' ' I received also from Java our Gryllotalpa vulgaris, certainly 

 transported to Java in the earth of some pots of plants. 



"In the Hymenoptera those transports are frequent only by 

 the ships, e.g., in 1854 our large Vespa crabro was caught for 

 the first time in North America, and now several of our wasps 

 have invaded the United States; they were not known at the time 

 of Say who first gave a good account of the United States 

 Hymenoptera. 



" I shall have your photographs placed in our museum with a 

 notice explaining what they are. 



" If you occupy yourself with Orthoptera I should be indebted 

 to you if you could send me a numerous set of the small Gryl- 

 lidae called Tridactylus or Xya, of which I could not well make 

 out the American species."

A NEW SCALE-INSECT OF THE GENUS LECANIUM. 



By T. D. A. Cockerell, Mesilla, N. Mex. 



Lecanium magnoliarum n. sp. ?.— Scale, 8 mm. long, 4^ wide, 2^ 

 high, elongate-oval, dark brown, the subdorsal area irregularly marked 

 with black or blackish ; dorsum bluntly keeled ; surface granular, little 

 shiny, with low wart-like protuberances at intervals, reminding one of the 

 skin of certain slugs of the genus Veronicella ; marginal area obscurely 

 radiate by darker lines, but not plicate. Removed from the twig the 

 scale leaves a white oval mark, the secretion abundant in the middle, and 

 forming a very distinct outline where the margin of the scale was, but not 

 indicating the place of the stigmatal incisions; 9 antennae 8-jointed, long 

 and slender. Formula 3 (451) (28) 67; 4 about }£ length of 3, 2 hardly 

 over half as long as 3, 6 very much shorter than 5, 2 with a pair of long 

 bristles near the end, 5 with a long bristle not far from the end, 8 with 

 several bristles; another example has 4 not over % length of 3, 8 short, 

 decidedly shorter than 2, 5 not quite so long as 4; formula 3 (41) 52 (86) 7. 

 Legs long and unusually slender, coxae and trochanter each with a bristle
