3. Zatypota patellata, new species 



Figure 324,k 



Front wing of male 3.5 to 4.3 mm. long, of female 3.5 to 5.5 mm. 

 long; nervulus varying from opposite basal vein to distad of it by 

 about 0.25 its length; discoidella present or absent, usually absent 

 in smaller specimens, very weak in medium-sized specimens, and 

 rather weak but pigmented in larger specimens. Otherwise struc- 

 turally indistinguishable from Z. parva. 



Black. Rim of antennal socket and apex of clypeus light brown; 

 mouth parts, scape and pedicel except above, tegula, subtegular 

 ridge, hind corner of pronotum, propleurum of male, usually part of 

 propleurum of female, anteroventral part of male pronotum, often 

 some of anteroventral margin of female pronotum, much of hinder 

 part of pronotum of male, most of mesepimeron, most of prepectus 

 of male, and small indefinite mark on mesepisternum next to middle 

 coxa, white or whitish; flagellum blackish brown, its base whitish 

 below; mesothorax, often much or most of pronotum, postscutellum, 

 and metapleurum, fulvous; front and middle coxae and all trochanters 

 white; front and middle legs beyond trochanters whitish in male, 

 stramineous or pale fulvous in female; hind coxa of male whitish, 

 tinged with fulvous basally; hind coxa of female fulvous; hind femur 

 fulvous, its apex white; hind tibia white, its basal third usually tinged 

 with pale brown, especially below, its apical 0.3 fuscous, the fuscous 

 a little more extensive below and less extensive above; hind tarsus 

 brown, the apex of the segments darker and the basal 0.3 of the 

 basal segment almost white. 



The cocoon is elongate elliptic, yellowish white, and made of an 

 open mesh of rather regularly looped, coarse silk. 



This species is closely related to Z. parva and seems to be its western 

 counterpart.
