OF THE TABANID.E OF THE UNITED STATES. 473 



Wiedemann. 



T. annulatus Sny. (Auss. Z\v., I, p. 185). Certainly not among tlie species of which I have specimens. 

 T. gracilis (Auss. Zw., I, p. 156, 71, Georgia) unknown; see T. tener O. S. No. 11. 

 T. nif/ri2)cs (Ibid., p. 142, 50) ; see No. 13, T. coffeatiis Macq. 

 Macquaet. 



■ T. bultimor(nsis (Dipt. Exot., 5' Suppl., p. 34 ; Baltimore). Perhaps T. costalis Wied.? 



T'. i*Vt//or (Ibid., 2" Su]ipl., p. 21 ; South Carolina). Perhaps T. glganteus DeGeer, fem.ale ? Compare 



tliis species (No. 37). 

 T. cCBA'io/asci'a^ws (Ibid., 5'' Suppl., p. 32 ; Baltimore). Perhaps 7'. 5(/^aHte;«s DeGeer, male ? See this 



species (No. 37). 

 T. carolinensis (Ibid., I, 1, p. 145; Carolina) ; belongs in the group of T. socius, or perhaps of T. micro- 



cephalus, asttcttis, etc. ? 

 T. cingulatus (Ibid., I, 1, y. 144, 46; Philadelphia). I do not recognize this species. 

 T. dorsonotatiis (Ibid., 2" SuiipL, p. 22; Carolina; a male). May be the male of T. riifiis Pal. No. 34, 



which I have not seen? 

 T. /(csconervosus (Ibid., I, 1, p. 147, 42; no locality; Walker, List, etc., I, p. 149, has it from Florida). 



May be T. turhidus Wied. No. 1. 

 T. hirtiocidatiis (Ibid., S' Suppl., p. 33, 128 ; Baltimore; a male). Ei/es pubescent. I do not know this 



species. The words "antennes .... a dent un peu allongee," may betray the male of my T. ceras- 

 tes No. 42. 

 T. ?zcm!/s (Ibid., 1" Suppl., p. 42, 88; Texas); see my T. psammopldlus No. 18; the name is preoccu- 



jiied by Wiedemann. 

 T. JSFovce Scotice (2= Suppl., p. 24, 110). Unrecognizable. 

 I". inmcUixnuis (2" Su|)pl., p. 23, 108 ; Philadelphia). Agrees exactly with T. lasiophthahnus No. 47, 



except that the pubescence of the eyes is not mentioned. In any case the name must be given up, 



.as there is an earlier T. jnmctipcmiis by Macquart himself; Dipt. Exot., I, 2, ]i. 185. 

 T. vicimis (Ibid., I, 1, p. 143, 44; Carolin.a) ; of the group of my T. socius No. 49. 

 T. unicolor (Ibid., 2' Suppl., p. 22, 107 ; Carolina). I no not know this species. There is a much earlier 



T. unicolor Wied. 



RONDANI. 



T. chelioptenis. I transcribe the rather inaccessible descrijition. (Female.) Ocidi nudi. Anlennce 

 superne in dentem non extensa;, fulvaj. J'alpi fulvescentes. Frons rufa. Fades sordide albicans. 

 Thorax dorso fulvo-rubescente, pleuris pauio grisescentibus. Scutdliim fulvo-rubescens, margine 

 paulo griseo. Abdomen fidvo-rufescens, segmentis penultinio et piiccedente in medio paulo fuscis ; 

 omnibus lineola margiuali postica, parum manifesta, sublutesccnte. Sqtiamcn et halteres fulvescentes. 

 Fedcs fulvo-rufi, tarsis vix obscurioribus, et geniculis angustissime lutescentibus. Aloi jiaulo infus- 

 catiE, circa venas aliquantnlum I'lisco lutescentes, ad venarum conjunctioiies fusco-nigricantis {sic) 

 maculataj. Stigmata et costa anguste fusco-lutea. Longit., millim. 18. Carolina. (Nuovi Annali 

 di Sc. Nat. di Bologna, Sept.-Oct., 1850.) 

 I do not know this sjiecies. 

 Walker. 



T. comes (List, etc., I, p. 172. T. inscitus; changed into T. comes, Ibid., V, p. 173; Hudson's Bay Terr. ; 

 Nova Scotia). The author describes a specimen without head. I find in my notes that when, in 

 1859, I visited the British Museum, T. comes was represented in it by five specimens, belonging to 

 three different species, all of them of the difficult groups of T. marffincdis Wied., or T. iUotus O. S. 



T. confusus (List, etc., I, ji. 147; Georgia). 



T. imituns (List, etc., I, p. 140; Geoi-gia). 

 Both of the group of T. abdomincdis ; peiliaps this very species. 



T. conterminus (Dipt. Saunders., p. 24 ; United States). The descri[iti()n of the abdomen suggests T. 

 costalis ; but the thorax is said to be gray, with hoary hairs. 



T. (briviitus (List, etc., I, p. 151 ; Nortli America). Walker says he describes a male; in the British 

 Museum I saw a single female specimen, whicli, at that time, I did not recognize. The description 

 Buc'gests nothing to me now, and is rather unmeaning. Tliere is some confusion in the Latin diag- 

 nosis, where in the third line, nigris must, I suppose, be read instead oi fulois.
