 ii. 839), with 250ssibly one or two others, almost con)i)Iete the vcnational transi- 

 tions between Somatina and Prohlepsis to which I have already (Novitates 

 ZooLOGiCAE xxii. 328) called attention. 



B. ITEOTROFICAI.. 



SuBFAM. HEBIITHEINAE. 

 13, Oospila floiepicta ab. pulchiipicta ab. nov, 



(J, 34-35 mm. Smaller than typical florepicta Warr., the markings brighter 

 red, with less dark admixture (beneath almost pure pinkish- vinaceous), their 

 moss-green edgings, as well as the moss-green basal patch of forewing, obsolescent.
