22 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. I3I 



♦lugubris Macq. 1838, Dipt. Exot., 1(1): 108. (Pangonia) M. P. = Esen- 

 beckia, Lutz (1909). Krober (i934)- 



♦lutzi Sure. 1921, Gen. Inseet., Taban. p. 54; 1923, Ann. Ent. Soc. France, 

 91(3) : 242. (Stigmatophthalmus) M. P. = Dasychela. Close to *D. riveti 

 Sure. Krober (1940) as Dicladocera (Stigmatophthalmus ) . St. altivagus 

 Lutz, the genotype, is quite different. Not listed by Krober (i934)- 



*macroceratus Big. 1892, 5:687. (Tabanus) B. M.(H) = *Pseudacanthocera 

 sylveirii (Macq.) 1838. Krober (1934)- 



*macrodonta Macq. 1839, Dipt. Exot., 1(2): 183. (Tabaniis) M. P.(H) = 

 Psalidia furcata (Wied.) 1828, Lutz (1907)- 



♦macula Macq. 1845, Dipt. Exot., Suppl. i : 43- (Tabanus) B. M.(H) = 

 ♦Dasychela aiiribarbis Macq. 1847. Krober (1940) as Dicladocera, with 

 auribarbis, argyrophorns Schin. 1868 and scutellatus Macq. 1839 as syno- 

 nyms. Bequaert and Renjifo (1946) as Dasychela with auribarbis Macq., 

 argyrophortis Schin. and submacula Wlk. 1850. The type of scutellatus Macq. 

 could not be found, but I doubt its identity with mactda. The type of *sub- 

 tnacida Wlk. is somewhat different though closely related. 



*maculifrons Krob. 1931, Stett. Ent. Zeitg., 92:277. (Agelanins {Archiplatius)) 

 B. M.(H) = *Dasybasis maculiceps (Krob.) 1934, nom. nov. Not Tabanus 

 maculifrons Hine 1907. 



♦maculinevris Macq. 1855, Dipt. Exot., Suppl. 5:31- (Tabanus) B. M. Krober 

 (1930a, 1934) as Stypommisa. Near *fidviventris Macq. (q.v.). 



*macnlipcnms Krob. 1929, Zool. Anz., 83(1-4): 52. (Stypommia) ; op. cit, 

 (5-8): 117. (Stypommisa) B. M.(H) = *Stenotabanus venosus Big. 

 1892. Not Tabanus maculipennis Wied. 1828, Brulle 1832, Macquart 1834, or 

 Macquart 1846. 



♦maculiventris Macq. 1850, Dipt. Exot., Suppl. 4:33- (Tabanus) M. P.(H) 

 = Dasybasis. Krober (1934) as Tabanus, with rubromaculatus Blanch. 1852 

 as synonym. The type is labeled "rubromarginatus Gay Chili," probably a 

 lapsus for rubromacidatus, as well as with its published name, so that all three 

 names refer to same specimens. 



♦maletectus Big. 1892, 5:664. (Atylotus) B. M. Krober (1934) as Tabanus. 

 The subepaulets are bare, labella fleshy, eyes bare, antenrtae missing. Frons 

 broad with large black callus filling lower third of frons. Perhaps best in 

 Dasybasis, but I do not recognize the species. 



♦mallophoroides Wlk. 1857, Trans. Ent. Soc. London, IV, 5:123. (Tabanus) 

 B. M. = *Stibasoma dyridophorum Knab 1913, Bequaert (i944)- Lutz 

 (1915) as Stibasoma. Krober (1934) as Stibasoma. Dyridophorum has less 

 yellow on dorsum of abdomen but otherwise same. It is possible that jestivum 

 Wied. and panamcnse Curr. are but races or color forms of the same species. 



*mamjcstus Wlk. 1850, Dipt. Saund., i : 41. (Tabanus) B. M. = Tabanus quin- 



quevittatus Wied. 1821, fide Philip in litt. 

 ♦marginata Macq. 1847, Dipt. Exot., Suppl. 2: 14. (Dichelacera) B. M.(H) = 



♦Dichelacera hinnulus Wlk. 1850, Ricardo (1904)- Lutz (1915)- 

 *marginatus Macq. 1848, Dipt. E.xot., Suppl. 3:172. (Tabanus) B. M. = 

 Tabanus. Not Tabanus margituitus Wlk. 1848 (November) Australia. 

 Ricardo's (1901) transference of Walker's species to Silvius makes it also 

 a homonym of marginatus Macq. 1838. Krober (i934) confused with Sihnus 

 marginatus Macq. 1838. The type is fragmentary and probably unidentifiable 

 with certainty.
