to second fiircal; otlier maculae at apex and near center of wing; a little more 

 broadly rounded at apex ; apex at or near termination of fourth f ureal ; first mar- 

 ginal cell very long; first cubital very short; second f ureal not sharply angulate 

 distally; second cubital not strongly arcuate; second marginal cell broad; radius 

 long, straight, except distally; cubital petiole about as long as discoidal subcosta. 



Male — Abdomen long, brown with light spots. Genital segment prominent, not 

 very large; genital plate with a lateral, basal elevation on each side, much smaller 

 caudad ; claspers rather small, slender, with an abrutly and briefly spatulate trans- 

 verse plate at apex, longer anteriorly than posteriorly; anal valve large; posterior 

 lobe conspicuously lanceolate and petiolate; axial epiphysis short, obtuse; pubes- 

 cence short, rather dense. 



Redeseribed from two males from England, determined by James Edwards. 

 This species, although it is European, is included in this paper because of the 

 fact that there is an American form extremely close to it. This has been de- 

 scribed as a variety of the European species. 



Aphalara nebulosa americana n. var. 

 (Figure 158, S; 159, R; 160, R) 



The principal structural differentiation between species and variety lies in the 

 labrum, male genitalia and forewing. The labrum in the variety is distinctly 

 smaller and less conspicuous ; the claspers of the male are distinctly larger ; trans- 

 verse plate almost as long as rest of clasper, while in the species it is but slighlty 

 more than half the length of clasper. Wing less darkly maculated; apical band 

 not complete across wing. Coloration is quite constant in species and variety. 



Described from one male in the C. F. Baker collection from Colorado. This 

 variety may be known in cabinets by the manuscript name of Aph. epilobii. 



Note: The name Trioza assimilis Crawf. is now changed to Trioza fori, since the former 

 name is preoccupied by T. assimilis Flor. 



In a p;iper just received from Dr. Kuwayama of Sapporo, Japan, a genus in Triozinae 

 has been named by him Epitrioza. Since the paper was pubhslied in 1909-1910 this name 

 has the right of priority over tlie genus of tlie same name published in a previous number 

 of tliis Journal (Vol. Ill, N'o. 1, 1911). The later name, therefore, may be changed now to 

 KuuHiyama Crawf. Also, a species of Trioza, occurring in Japan has been named by him 

 Trioza nigra. This also antedates the species of the same name described by myself in the 

 Journal of December, 1910. This species may be known hereafter by the name Trioza 

 nigrilla Crawf., instead of Trioza nigra Crawf. The name Neotrioza Crawf. is, also, pre- 

 occupied by Neotrioza machili Kieffer (1905). My Neotrioza may be known as Neotriozella 

 Crawf.
