closely matches Lutz’ description and figure of uruguayen- 
sis. Three other specimens recently received also match 
Lutz’ species. These were collected by Juan Foerster on 
February 15, 1953 at Isla Berna in the delta of the Paraiul 
River near Tigre, Province of Buenos Aires, Argentina. 
C. Patricia is easily separated from Uruguay ensis Lutz by 
the hyaline apical portion of the fourth posterior cell, uni- 
formly narrow apical spot united for almost its full width 
with the crossband (apical spot expanded apically and 
just barely united with the crossband in uruguayensis) and 
by the outer margin of the crossband which is relatively 
straight below the third longitudinal vein and somewhat 
irregular in uruguayensis. 
Krober thought what he considered to be uruguayensis 
might be the same as bonariensis Brethes but on a basis of 
Hack’s recent paper (1951) they must be quite different. 
The species redescribed by Hack, who had access to Brethes’ 
type, is either the same or closely related to C. frifaria 
Macquart. 
Some of the specimens of C. patricia received from the 
Museum of Comparative Zoology, through the cooperation 
of Dr. J. C. Bequaert, were labeled paraguayensis Brethes. 
Dr. Hack kindly sent a redescription of the type of C. Para- 
guay ensis to the writer and this indicates that this species 
lacks an apical spot and the crossband is straight from the 
costa to the posterior margin of the wing. C. paraguayensis 
evidently is closely related to C. formosa Krober and may 
be the same although the known range of the two forms is 
rather widely separated.
