90. ZENILUA PROSPERINA Brauer and Bergenstamm 



Sisyropa proserpina Brauer and Bergenstamm, Denk. Wien. Akad. Wiss., 

 vol. 58, 1891, p. 347. 



One male, " Brasilien," with Brauer and Bergenstamm label. The 

 undoubted type. The species has been described by Brauer and 

 Bergenstamm and shows few noteworthy additional characters. It 

 is a large robust form, which would readily go in Exorista of authors 

 {Zenillia as used by Aldrich and Webber). Palpi dark yellow, 

 covered with dense black hairs; dorsocentral 3, 4; presutural 2; 

 sternopleural 2, 1; scutellum with 3 lateral, 1 apical decussate and 

 depressed; pteropleural minute. No cliscals on second and third 

 abdominal segments, on which the dark pattern takes the form of 

 a broad median stripe and a lateral triangle, which is contiguous 

 and does not reach the front edge. The third tergite has no cluster 

 of hairs below. Middle tibia with one bristle on outer front side; 

 ])ind tibia ciliate; tarsi with long claws and pulvilli. 



The species is not in the National Museum. 



91. WINTHEMIA XANTHOCERA Wiedemann 



Tachina wanthocera Wiedemann, Auss. Zweifl., vol. 2, 1830, p. 329. 

 Masipoda wanthocera Bratjee and Bergenstamm, Denk. Wien. Akad. Wiss., 

 vol. 56, 1889, p. 163 ; vol. 58, 1891, p. 402 ; vol. 60, 1893, p. 123. 



One female, " Brasilien " ; an old folded label reads " xanthocera 

 Wied. Coll. Winthem." Agrees with description except that the 

 front is cinereous pollinose with dark red stripe, and the antennae 

 are more reddish -brown than reddish -yellow. I believe it is one 

 of the type series, of which Wiedemann had at least two. It is 

 a true Winthemia (syn. Masipoda)^ in spite of the fact that even 

 under a high power it shows not a single parafacial hair. Other- 

 wise it has the characteristic structure of the genus throughout, in- 

 cluding the tubular ovipositor. The second abdominal segment has 

 a single large pair of marginals ; the middle tibia has a single bristle 

 on the outer front side near middle ; there are only two sternopleurals. 



One female in the National Museum, collected at Bartica, British 

 Guiana, June 7, 1901, agrees remarkably throughout except that 

 under a high power it shows two or three pale slender hairs on the 

 parafacial. Provisionally I regard this as the same species. Only 

 the discovery of the male can clear the species up any further. 



92, URAMYIA PRODUCTA Robinean-Desvoidy 



IJramyia producta Robineau-Desvoidy, Myodaires, 1830, p. 204. — Bratjek 

 and Bergenstamm, Denk. Wien. Akad. Wiss., vol. 58, 1891, p. 130; vol. 60, 

 1893, p. 135. 



Two males ; one labeled " Schott Brasilien," the other " Bahia 

 Coll. Winthem."
