APHALAROIDA SPINIFERA, new species. 

 Fig. 399. 



Length of body 1.7 mm.; length of forewing 2. General color 

 brown, with orange markmgs, sometimes more uniformly orange 

 to yellowish (probably immature forms) ; vertex orange on lateral half 

 of each lobe; pronotum and prsescutum orange on posterior portion; 

 scutum orange on median dorsal line and around wing bases, and a 

 narrow arcuate line halfway between these; venter dark; forewings 

 whitish, with irregular brown maculae, usually as represented in 

 figure, sometimes less maculated; some forms are lighter with only 

 a few small scattered maculas on the wings. 



Head, thorax, wings, legs, and abdomen (to a less extent) densely, 

 often very densely, covered with long white hairs which are usually 

 clavate because of the excretions on them; sometimes the hairs are 

 fewer or even almost wanting in rare instances. Head distinctly nar- 

 rower than thorax, deflexed somewhat, similar in general to type 

 species; antennae one and a half times as long as width of head. 

 Thorax long, rather broad. Wings over two and a haK times as 

 long as broad, coriaceous, maculated, rhomboidal, apex at termina- 

 tion of radial sector; first marginal cell larger than second. 



Genitalia. — Male. — Resemble type species; forceps stout, about 

 twice as long as broad, oval; anal valve nearly twice as long as forceps, 

 converging a little toward apex. Female. — Genital segment stout, 

 shorter than rest of abdomen, subacute at apex. 



Described from 30 males and females from Tucson, Arizona 

 (H. G. Hubbard), on Prosopis julijlor, in December and January; 7 

 from Palm Springs, California (Hubbard), on Phoradendron, growing 

 on Acacia gregii; 16 from Argus and Panamint Mountains, California 

 (Koebele), April. All in the collection of the United States National 

 Museum. The Arizona specimens bear the label Rhinocola sjnnifera, a 

 manuscript name; the California forms are labeled Rhinocola rauca, 

 but are apparently the same species.

APHALAROIDA PROSOPIS, new species. 



Fig. ■104. 



Length of body 1.7 mm.; length of forewing 1.5. General color 

 dark brown to black uniformly; forewings maculated with dark 

 brown, as in figure. Body small. Glandular hairs dense, but short, 

 on head, thorax, and wings and sometimes the legs. 



Head narrower than thorax, deflexed; antennae a little longer than 

 width of head. Eyes small. Thorax arched somewhat; pronotum 

 moderately long; meso-episternum prominently bulging between 

 fore and middle coxae. Forewings small, coriaceous, rhomboidal 

 slightly, with apex between radial sector and medial branch, less
