* This name never really referred to this species at all, but belongs to a North 

 American Strymonid. It was originally described by Fabricius, Ent. Syst., iii., 

 pt. i., p. 297, as follows : — 



" H. K. alis integerrimis fuscis immaculatis ; posticis subtus ocellatis 

 strigaque postica maculari fulva. 



Papilio Titus. Jon. fig. pict. 6. Tab. 44, fig. 2. 

 Habitat in Anglia, Dom. Drury. 



The same size as the preceding [Artaxerxes, &c] . All wings fuscous above, 

 without spots. Beneath also fuscous, the upper with a marginal streak of small 

 black and white lines, the lower with a small median line, and a streak of black 

 dots surrounded by white. Towards the margin red spots marked with a black 

 dot." 



Haworth (Brit. Lep., p. 47) observes that it had never been found in England, 

 Fabricius having made this statement through erroneous information. Westwood, 

 in his letterpress to Humphreys' British Butterflies, &c, p. 117, states that 

 Haworth was well acquainted with Mr. Jones, whose drawing was the authority for 

 the description given by Fabricius, from information supplied by Mr. Drury, in 

 whose collection the specimen existed. Stephens (Cat. Diurn. Lep., p. 191), under 

 the heading Strymon titus, says : " The specimen of P. titus in the National Col- 

 lection bears an old label, on which is written l Titus 130,' evidently a reference to 

 the description by Fabricius. It is quite possible that this is the type from Drury's 

 coll., received through Mr. Milne, as it answers in every particular to the descrip- 

 tion and has altogether the appearance of a very old specimen ; its true habitat 

 appears to be New England." The specimen is still (May, 1912) in the Brit. Mns. 

 coll., and is labelled " Milne coll. from Drury coll., probably the type." Stephens 

 in his Illustrations i., p. 5, 1828, and i-n his first Catalogue, 1850, had given it as 

 a species of Polyommatus. Westwood and Hewitson (Gen. Diurn. Lep., ii., p. 494) 

 give it as a Lycaena, but refer to Strymon mopsus as a synonym. Godart (Ency. 

 Meth., ix., p. 688) also gives it as a species of Polyommatus. Duponchel (Pap. de 

 France, suppl. i., p. 58, note) observes that it was not found in any collection in 

 Paris, but was reported by Fabricius to occur in Scotland. De Villiers and Guenee 

 (Tab. Syn., p. 20) give it under " Agestis," of which they take it to be a casual 

 aberration. They add that Curtis and other British entomologists had assured 

 Lefebvre that it was neither taken in England or Scotland. By modern American 

 authors (Fernald, French, Scudder, &c) it is always given in its proper place, as 

 Strymon (or Thecla) titus. I should not have introduced the name here but for a 

 note in Tutt's writing, " titus is astrai'die^' leaving me, as he often did, to work 

 out its history. — (G. W.) 



f Lewin's idas much more nearly resembles argus (aegon) ? on the underside, 

 but as he figures this species on the same plate, and says of his idas : " This is a 

 common butterfly with us, and to be taken in almost every dry pasture field and in 

 the open parts of woods," and moreover states definitely that his figure of idas 

 represents the j , there can be no doubt that his idas is medon. His nomenclature 

 was followed by most English writers before Stephens.
