3. Joppidluna arizonicum, new species 



Male: Frontwmg9.8 to 12.5 mm. long; mesopleurum of male with fine, 

 weak, moderately sparse punctures and traces of longitudinal wrinkling 

 that occupy about 10% of its surface; mesopleurum of female with 

 close oblique wrinlding on about 70% of its surface, the rest with 

 fine, rather weak punctures; metapleurum of male smooth, with 

 fine, weak punctures that are separated by about 2.0 their diameter; 

 metapleurum of female with fine, moderately strong punctures that 

 are separated by about 1.5 their diameter, these overlaid by moder- 

 ately close, oblique wrinkles on about 75% of the area; basal carina 

 of propodeum complete and sharp; propodeum beyond basal carina 

 in male with rather coarse transverse wrinkles on apical half, the 

 basal half smooth except for rather sparse, weak punctures; pro- 

 podeum beyond basal carina in female with sharp, regular, transverse 

 wrinldes all over. 



Ferruginous, the wings black. Flagellum of male light reddish 

 brown, with a yellowish band that occupies about four segments; 

 basal 3.4 flagellar segments of female reddish brown, the next 6.6 

 segments pale yellow, the rest black; front and middle tibiae and 

 tarsi yellow with a faint fulvous tinge, the tarsi fulvous apically; 

 hind tibia yellow, its basal 0.11 ± and apical 0.1S± fulvous; hind 

 tarsus yellow, the incisures and the apical two segments fulvous. 



Female: Unknown,

4. Joppidium densum, new species 



Front wing 11 to 14 mm. long; mesopleurum and metapleurum of 

 male with medium-sized, mostly weak punctures that are separated 

 by about their diameter, about 35% of their surfaces covered with 

 rather fine longitudinal wrmkles; mesopleurum and metapleurum 

 of female with moderately dense punctures that are in most places 

 obscured or obhterated by dense, rather fine, longitudinal wrinkles, 

 the wrinkles covering all of metapleurum and about 85% of meso- 

 pleurum ; basal carina of propodeum complete and sharp ; propodeum 

 beyond basal carina covered with transverse wrinkles that are denser, 

 finer, and more regular in female than in male. 



Ferruginous, the wings black. Flagellum of male blackish with a 

 yellowish band that occupies about four segments; flagellum of 

 female with first four segments reddish brown, the next 6± yellowish, 

 the rest black; more or less of deeper thoracic sutures and protected 

 areas on lower part of thorax, blackish; front and middle tibiae and
