McDunnough (1934) applied the name pulverosana to some speci- 

 mens from Canada, although with some doubts. The present author 

 has no objection to this application of the above name, because the 

 external characters of the specimens with the genitalia of McDunnough 

 conception of pulverosana correspond quite well to the type of this 

 species. AIcDunnough treated pulverosana as a separate species, but, 

 as he wrote himself, the genitalic distinction between it and hastiana 

 is minimal, and the females of the two species cannot be satisfac- 

 torily differentiated. The socii of the male genitaha pulverosana 

 are less distmct distally and more nearly circular in outline, the 

 aedoeagus is slightly longer and narrower, and the armature of the 

 vesica consists of three cornuti. In both pulverosana and hastiana, 

 a triangular piece of chitin is present in the armature of the vesica. 



The latter character seems to the present author to be of special 

 taxonomic significance when considering pulverosana and hastiana as 

 being conspecific. The number of cornuti varies in hastiana from 

 three to six (Obraztsov, 1949); even in some Canadian specimens of 

 hastiana, there are only three cornuti present, as in pulverosana. In 

 the European specmiens of hastiana, many of which were examined 

 by the present author, the cornuti vary in their thickness and length. 

 The shape of the socii is also inconstant in large series of hastiana, 

 and some European specimens have nearly circular socii. Inasmuch 

 as in Manitoba both pulverosana and hastiana are present, there is 

 no reason to suppose in pulverosana a geographical subspecies of 

 hastiana, and it should be treated as an individual form. Until a 

 revision of individual variation of hastiana in North America is done, 

 pulverosana becomes a synonym of hastiana. 



The present author examined some specimens which belong in aU 

 probability to hastiana but which have no cornuti. In a series from 

 WatsonviUe, Calif. (September 1919, D. Penny ; genitaha on sHdes 1-Obr., 

 2-Obr., and 3-Obr., Jan 5, 1959; in USNM), consisting of three males, 

 one specimen only has four minute dots of the vesica, which show the 

 places on which the cornuti were fixed. There is also a male specimen 

 Nvithout cornuti from Verdi, Nev. (June 20-30, A. H. Vachell; genitalia 

 on sHde 434-Obr.; AMNH).
