The Magnolia Soft Scale 



Neolecanium comuparvum (Thro.) 



Plate 19, Fig. 13; Plate 20, Fig. 6 



Leca/nium comuparvum Thro, Bui. 209, Cornell Exp. Sta., p. 216 (1903). 



This large flat scale has been erroneously determined and discussed 

 by a few writers under the name L. magnoliarum, and has existed 

 scientifically undescribed until 1903, although not an uncommon 

 insect. It occurs on various species of Magnolias, including the 

 deciduous M. acuminata of the Northern States. The pink color of 

 the growing female scale is somewhat hidden by the covering of fine 

 powdered wax, which also fills the spiracular grooves on the ventral 

 surface and remains as four distinct white lines after the removal 

 of the scale from its host. 



The adult females average 8 — 10 mm. long and 5 — 8 mm. broad. 

 When cleared and mounted the derm is seen to be crowded with large 

 pores, and the very short reduced antennae and legs are scarcely 

 noticeable. 



It has been reported from New York, Ohio, Pennsylvania, Maryland, 

 Virginia and Louisiana. 



A NEW ENEMY OF THE FLORIDA ORANGE 



By E. A. Back, Orlando, Fla. 



The purpose of this notice is merely to call the attention of 

 Entomologists to the discovery for the first time in this country of 

 another pest of the citrus tree. In view of the widespread havoc 

 played among the orange groves of Florida by the Citrus white fly, 

 A. citri Riley and Howard, and the Spotted- wing, A. nubifera Berger, 

 the discovery of another Aleyrodid which already has demonstrated 

 itself to be of economic importance is interesting. 



While recently examining orange trees along several streets in the 

 business section of Tampa in connection with the white fly investi- 

 gations being carried on in Florida by the Bureau of Entomology, the 

 attention of the writer was attracted to dense white or grayish wooUy 

 secretions concealing the under surfaces of many leaves. At first this 

 was supposed to be a heavy infestation of the usually scarce Paraley- 

 rodes persece Quaintance, but on closer examination proved to be 

 Aleyrodes hoivardi Quaintance, which until the present time has been 

 known only to infest the orange trees of the West Indian Islands. In
