Takahashi (R.). On some Species of the Genus Nipponaphis, Pergande 

 (Aphididae, Hemiptera). — Bull. Brooklyn Entom. Soc, Brooklyn, 

 N.Y., XV, no. 4, October 1920, pp. 115-116. 



The second generation (migrant) of Nipponaphis distyfoliae, sp. n., 

 from Japan is here described. This Aphid produces very prominent 

 galls on the leaves of its winter host, Distylium racemosnm, which start 

 about April and reach full development in May. The stem-mother is 

 wingless, but the females of the second generation are winged, and 

 migrate to Quercus glandulifera or some closely allied tree in June. 

 The succeeding generations are wingless and non-migrato;y, the 

 winged sexnparae appearing in October and November. 



The genus Nipponaphis, of which ScJiizoneiiraphis is regarded as a 

 synonym, has been recorded only from Japan and Java. From the 

 former country three other species are known, A'^. yanonis, Mats., 

 N. distylii, Perg., and N. cuspidatae, Essig & Kuw., the latter being 

 the only one with a single food-plant and not producing galls.

 gossvpiclla, S.) — Texas State Dept. A^ric., Austin, Bull. i:>5, March- 

 Apnl 1919, 459 pp., 74 figs. [Received 10th November 1920.] 



The prevention of a general invasion of the cotton bc>lt of the United 

 States by Platyedra {Pectinophora) gossypiella (pink bollworm of cotton) 

 and the extermination of k)cal outbreaks is probably the greatest 

 entomological problem of the southern United States.
