Apterous Viviparous Female 



Bright pea green, larger than the akite form ; antennae and distal two thirds 

 of cornicles black; body more than half as broad as long (excluding cauda) ; 

 eyes red ; antennae reaching just beyond tip of cauda, black, except joints I, 

 II and base of III very similar to that of the winged female ; legs pale green ; 

 apices of tibiae and tarsi dark brown ; cornicles not quite reaching tip of 

 cauda ; cauda green, tapering, about one half the length of cornicles ; beak 

 short, barely reaching second coxfe, the tip black. 



The young are very pale, with large red eyes and the distal antennal joint 

 dusky. Found sparingly among the flower spikes of Orthocarpus purpura- 

 scens in April. 



Scientific Notes 



stable Fly. In the Bulletin de la Societe Nationale d'Acclimatation de 

 France, March, 1909, Lucien Iches has published a very interesting article on 

 Stomoxys calcitraus and Argentine cattle, giving the results of a brief in- 

 vestigation made by him last year in the province of Santa Fe, Argentina. 

 Stomoxys calcitrans swarmed on a large estate in almost incredible numbers. 

 The cattle were nearly driven crazy by them. Certain valuable Durham bulls 

 which were observed were covered with flies, had lost their hair in large spots, 

 and the skin was cracking. Monsieur Iches naturally sought at once for the 

 principal breeding places of the flies, and found them to be in the stacks of 

 debris from the threshing of wheat and flax. Larvse and puparia were found 

 by the millions in the lower portions of these piles of straw, where some 

 fermentation had already begun. The sensible measure which he recom- 

 mended was to have this debris burned within forty-eight hours after the 

 completion of the threshing, the ashes being used for fertilizing purposes. It 

 seems that there exists in the province of Santa Fe an old provincial law or- 

 dering the burning of the debris after threshing, but that it has not been en- 

 forced of late years. L. O. H. 



Insects on Imported Nursery Stock. The discovery of the nests of the 

 brown-tail moth on foreign importations of seedlings into the State of New 

 York has prompted a very close inspection of nursery plantations this 

 summer for caterpillars of this species, which might possibly have escaped 

 treatment at the time of the planting of the stock in the nurseries. With 

 this close supervision of nurseries, there have been found on foreign seed- 

 lings eggs of the Rusty Tussock Moth (Notolophtis antiqua Linn.) and sev- 

 eral colonies of the larv:e of the Little Ermine Moth (^Hyponomeuta padella 

 Linn.) which were feeding on cherries. These were collected and brought 

 into our laboratory for identiflcation by Messrs. Fred Wiley and John Maney 

 respectively, who are official nursery inspectors. 



According to Judeich and Nitsche, H. padella thrives on the service tree, 

 wild plum, hawthorn, medlar and on various species of Pyrus. Theobald 

 says that in England this species feeds normally on hawthorn, often quite 

 defoliating hedgerows, and also attacks cherry and plum. In France it is 

 said to subsist on cherry and plum and in Italy on plum.
