to second f ureal ; other mnculie at aj)ex and near center of wing; a little more 

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

 ginal cell very long; first cubital very siiort; second furcal not slinrply angulate 

 (listally: second cubital not strongly arcuate; second marginal cell broad; radius 

 long, straight, except distally; cubital petiole alwut as long as discuidal suln-osta. 



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

 very large; genital jjlate with a lateral, basal elevation on each side, nmcli smaller 

 caudad; claspers ratlier small, slender, with an abrutly and brieHy spatulate trans- 

 verse plate at apex, longcT anti-riorly tlian posteriorly; anal valve large; posterior 

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

 cence short, rather dense. 



Redescribed from two males from England , determined by Jjimes 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 ii. var. 

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



The principal structural ditferentiation between species and variety lies in the 

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

 smaller and less consjjicuous ; the clasjiers of the male are distinctly larger; trans- 

 verse plate almost as long as rest of claspcr, while in the sj)ecies it is but slighlty 

 more than half the lengtli of elasper. Wing less darkly maculated; apical band 

 not complete across wing. C"oloration 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. cpilobii. 



Note: The name Trioza at»imili» Crawf. is now rlianpcd to Trioza flori, since the former 

 name is ]>re<)eeuj)iecl l)y T. ossimilu Flor. 



In a paper just received from Dr. Kuwayaiiiii of Siipporo, .Inpnn, n pcnus in Triozinac 

 has Ih-cu named by him Kpitriaza. Since the paper was |)ul>li>lied in I909-IOIO this name 

 has the ri)rht of priority over the genus of the same name piihlishe<l in a previous niHnl>cr 

 of this Journal (Vol. Ill, No. I, 1911). The Inter name, therefore, may he chnnped now to 

 /i iiiroi/aiiiii Crawf. .Mso, a species of Trinzn, oeeurrinp in .Japan has In-en named by him 

 Trioza ini/rii. This also antedates the species of the same name descrilH-d by myself in the 

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

 nigrilla Crawf., instead of Trioza niijra Crawf. The name Xrntrioza Crawf. is, also, pre- 

 occupied by Xeotrioza nuirhili Kicffcr (1905). .Mv Seolrioza may be known as Xiotrioztlla 

 Crawf.
