Wien, xiii, 1108 (1863), aud "Walker's L. turpis in Ins. Br. Dipt., iii, 

 300 (1856), but Walker described another L. turpis in Ins. Sauud., 

 434 (1856) ; which of Walker's species has priority I do not know, 

 the preface in Ins. Br. Dipt, being dated Febi'uary, 1856, while that 

 of Ins. Saund. is January ISth, 1856 ; under the doubt and careless- 

 ness I think both Walker's names had better cease. Prior to Eg:e:er's 

 again is Osten-JSacken's description of D. pubipennis, Pr. Ac. Nat. 

 Sc. Phil., 211 (1859), which I expect will prove to be the same species, 

 but I dare not adopt the name of an American species without close 

 comparison with European specimens ; after all I think Meigen's L. 

 fusca, Sys. Bes., I, 133, t. 4, f. 19 (1818), will prove to be this species, 

 and then there can be no doubt as to priority of nomenclature ; in the 

 mean time Egger's name "holds the field." The species seems to be 

 not very uncommon in the south of England, as I have taken it in 

 Kent, Sussex, Hampshire aud Devonshire during the last two years. 



D. modesta, Mg. : this species may be known at once by its verti- 

 cillate antennae with elongate joints ; I have not the least doubt that 

 I have the species intended by Meigen (Sys. Bes., I, 134), and Zetter- 

 stedt (Dipt. Skan.jX, 3863, whei*e the antennre are described in detail), 

 but I am very doubtful about Schiner and others, by whom the species 

 of Dicranomyia have been very insufficiently studied, and it is certainly 

 not the species so called by Osten-Sacken (Stet. Ent. Zeit., xv, 211). 

 They all require very close study of the male genitalia, and by help of 

 these characters I believe at least two more British species will be 

 distinguished, only the material at my disposal is unsatisfactory ; how- 

 ever, apart from the genitalia, the antennae will always distinguish D. 

 modesta from any other species I am acquainted with. I catch it 

 abundantly in August and September near Mildenhall and Exning in 

 Suffolk, also in June in the New Forest, and late in August in ex- 

 treme South Devon (Slapton). 



D. cliorea, Mg. : this is the commonest species of all the Tipulidce 

 and Limnoliadce, occurring in every gai-den or wood throughout Great 

 Britain, and yet it is still to me a most unsatisfactory species ; in its 

 commonest and most typical form it has a distinct reuiform stigma 

 and infuscated cross veins, in which state it is easy to distinguish, but 

 its markings fade off so much that specimens without the infuscated 

 cross vein are very puzzling. I hope, by further examination of the 

 male genitalia in a living state, to come to more definite conclusions. 

 The allied species in Britain are what I call D. stigmatica, lutea, mitis, 

 aud one or two more ; stigmatica I am not at all satisfied with ; by it
