below entrance of ductus bursae; seventh sternum with short upraised 

 ridge in middle below ostium bursae and with a single long shallow 

 pouch along anterior margin. 



Comparative remarks. — This genus is not so closely related to Cincia, 

 Amplicincia, and Paracincia as those genera are to one another. 

 Parvicincia differs greatly from these genera in the filiform anteima of 

 the male, in the lack of the juxta of anellus, and in the nearly straight 

 aedeagus with bulbus ejaculatorius from near the anterior end. In 

 the females, Parvicincia differs from the other genera m the lack of 

 internal circlet of spines in the bursa copulatrix and in the presence of 

 two signa, one hmular in shape. Also, the females have no cupules, 

 having instead a single long shallow pouch along the anterior margin. 



A single new species, Parvicincia belli, is included here. 



PARVICINCIA BELLI, new species 



Male. — Palpus dark brown, sometimes nearly black. Antenna and 

 head ochraceous-white, sometimes darker and often with a few dark 

 scales in middle of vertex. Thorax ochraceous-white or darker, with 

 a pair of small black spots on posterior margin of mesoscutellum. 

 Foreleg with apex of tibia, apex of first tarsal segment, and all of 

 second through fifth tarsal segments dark brown, nearly black. 

 Dark-brown spots in middle of midtibia and at apex of first midtarsal 

 segment. Hind legs and remainder of fore and mid legs unicolorous 

 ochraceous-white. Abdomen ochraceous-white below, slightly darker 

 above. Forewing above grayish white, sometimes more fuscous, ir- 

 rorated with black scales and with numerous small dark brown or 

 black spots as follows: A small basal spot in middle of wing; an oblique 

 subbasal series of three spots ; an antemedial series of four spots bent 

 inward to costa and outward above inner margin; medial spots on 

 costa, and between cell and base of vein 2 ; a spot at upper angle and 

 one at lower angle of cell and one on costa above these and below 

 middle of vein 2; several subapical spots at costa and below veins 6 

 and 5; five or six marginal spots between veins at outer margin. 

 Fringe concolorous with ground color of wing. Forewing fuscous 

 below, paler dirty white along lower margin and through middle of 

 costa, which has a series of two or three black spots. Hind wings 

 above and below fuscous with slightly paler fringes and slightly paler 

 base underneath. An indefinite oblong patch of modified scales 

 above cell of hind wing and usually covered by fore wing. These 

 scales concolorous with rest of wing or sometimes ochraceous, slightly 

 thicker, longer and narrower than the normal scales. 



Length of forewing, 7.5-8.5 mm.
