NO. 3 NEOTROPICAL FLIES, TABANIDAE — FAIRCHILD I9 



treat as Catachlorops. Specimen in B. M. det. immaculata by Krober agrees 

 with type of *Catachlorops juscipcnnis Macq. The type of immaculata is very 

 close to flavus Wied. and vespertina Beq. and will go into Amphichlorops. 

 (N.S.) 



♦immaculata Krob, 1930, Stett. Ent. Zeitg., 91(2) : 148. (Rhinotriclista) B. M. 

 = Scione, Krober (1934). 



*imponens Wlk. 1857, Trans. Ent. Soc. London, 4: 122. (Tabanus) B. M.(H) 

 i=z Tabanus olivaceiventris Macq. 1847 (N.S.) = *Atylotus pulverulenius 

 Big. 1892. Krober (1929a) as (Lophotabanns) with pulverulentits as syn. 

 Bequaert (1926). 



*importiinus Macq. 1847, Dipt. Exot., Suppl. 2: 18. (Tabanus) B. M. = (Neo- 

 tabanus), Krober 1933. Not T. importunus Wied. 1828. Type very dirty and 

 denuded, apparently a member of lineola complex. 



*incertiis Macq. 1838, Dipt. Exot., 1(1) : 151. (Tabanus) M. P.(H) = Tabanus 

 nebulosus de Geer 1776 = *T. ferrifer Wlk. 1850. Not 7". palpalis var. 

 inccrtus Szil. 1926, East Indies. Blanchard's (1852) reference of specimens 

 from Chile repeated by Krober (1934) is certainly an error. (N.S.) 



♦incipiens Wlk. i860, Trans. Ent. Soc. London, 5:275. (Tabanus) B. M. = 

 Stenotabanus, Krober (i93oh, 1934). Type headless, subepaulets bare. Near 

 St. macidijrons Hine, but probably now indeterminable with any certainty. 



♦incisa Macq. 1845, Dipt. Exot., Suppl. 1:177. (Chrysops) B. M.(H) = 

 *Chrysops brasiliensis Ric. 1901 = C. fiilviceps, Krober 1925, Bequaert 1940. 

 = ? C. julviceps Wlk. 1845. =C aurofasciata Krob. 1926. (N.S.) Not 

 C. julviceps Lutz 1909. Not C. incisa Fairchild 1942. There are 3 $ cotypes; 

 the one bearing Macquart's hand label has been selected and labeled as lecto- 

 type. The others are different species. 



Hncisuralis Macq. 1847, Dipt. Exot., Suppl. 2: 12. (Pangonia) B. M. = ? Fi- 

 dena opaca (Brethes) 1910 =: Fidena albibarba End. 1925, p. 293, not 

 Melpia atiribarba var. albibarba End. 1925, p. 276 = Fidena abominata Philip 

 1941 = ?? Tanyglossa hirsuta Thunberg (1827, Nova Acta R. Soc. Sci. 

 Upsala, 9:67, Brasilia). Not Pangonia incisuralis Say 1823. Enderlein 

 (1925) as syn. of hirsuta Thunb. and says incisuralis Lutz (1909) = albi- 

 barba End. Krober (1933b, 1934) lists as a valid species of Fidena and saw 

 type. Castro (1945) identifies incisuralis of Lutz (1909) with longipalpis 

 End. 1925. All specimens seen by Lutz, Enderlein, Brethes, Castro, and my- 

 self are from southern Brazil and Argentina. The eyes are practically bare 

 and frons with a pair of low bosses at base. The correct name for this 

 species must await examination of Brethes and Thunberg's types, if still in 

 existence. 

 incompleta Macq. 1845, Dipt. Exot., Suppl. 1:27. c? $; 1850, op. cit. Suppl. 

 4:25. (Pangonia) M. P. Only a female remains in Paris and its labeling 

 indicates it may not be the ? studied in 1845. The description was mainly 

 based on the male, which seems to have been a different species, as noted by 

 Schiner (1868) and Szilady (1926). Krober (1930J) as Scione, but his 

 description indicates a different species. Schiner (1868) as genotype of 

 Diclisa. The specimen in Mus. Paris is very close to *Sc. minor Macq. (q.v.), 

 but with frons a little wider, palps, subcallus, and legs uniformly brown, no 

 median black patches on abdomen. It would seem that the validity of the 

 name must rest on the description of the <? rather than the specimen in Paris.
