subapically. Female. — Genital segment large, longer than rest of 

 abdomen, dorsal valve a little longer than ventral. 



Described from several males and females from American Forks, 

 Utah (Hubbard and Schwarz), June 24; Colorado (no data); one 

 male from Pernitz, Austria (determined by Franz Loew). Edward's 

 artemisise ('96:232) is a totally different species, named by Oshanin 

 ('07:344) piZosa. 



Closely related to this species is a long series of forms which show 

 more or less pronounced differences and many close similarities. 

 Some of these, though not all, have been separated off and assigned 

 to distinct species.

Figs. 162, 378, 502, 503. 



A. artemisise angustipennis Crawford 'llb:499. — Patch '12b:218. 



Similar to artemisise, differing as f oUows : Size usually larger, some- 

 times much larger; length to tip of folded wings varying from 2.3 

 to 3.5 mm. Color flavous; scutellum with several more or less dis- 

 tinct whitish stripes; antennae black at tip. Wings relatively nar- 

 rower and longer, usually nearly three times as long as broad, more 

 densely covered with similar brown spots which are often crowded 

 together so closely that they run together and form more extensive 

 maculae. Genitalia similar, but larger. 



Described from numerous specimens from many localities: Clare- 

 mont and Berkeley, California (Crawford), on Artemisia calif ornica, 

 June to September; Los Angeles, California (Coquillett), no data; 

 Hood River, Oregon (A. Koebele), May 21; Easton, Washington 

 (Koebele); Wasatch Mountains, Utah (Hubbard and Schwarz), June 

 20, 1885; Colorado (Gillette), no data; Black Hills, South Dakota 

 (J. L. Webb), July 11; Oakland, Maryland (Hubbard and Schwarz), 

 July 10. Some of these bear the manuscript name of .Aplialara 

 angustipennis Riley, and others A. utahensis Riley, but some of the 

 latter seem to belong to artemisise, as described above. 



Type-specimen in author's collection. 



APHALARA VIRIDIS, new species. 



Color greenish or greenish yellow thi"oughout; wings rather 

 sparsely covered with small, round, brown spots, as in artemisise, 

 membrane thick and whitish. Female genital segment distinctly 

 shorter than in artemisise, and with long hairs on dorsal side of dorsal 

 valve caudad, instead of the short pubescence characteristic of the 

 related species. Male genitalia similar to artemisise. 



More closely related to artemisise than to angustipennis, being 

 similar in size and general proportions to the former.
