APPENDIX. 483 



Roths, and Jord., siehei, Piingeler, centralasiae, Bienert, robertsi, Butl., 

 nervosa, Roth?, and Jord., costata, Nordm. The three recognised 

 local forms are paralias, Nick., rubescens, Garb., grentzenbergi, Staud. 

 The aberrations noted are helioscopiae, Selys-Longch., lafitolii, Thierry- 

 Mieg, esulae, Bdv. (nigrescens, Roths, and Jord.) and restricta, Roths, 

 and Jordan. We have in our account of H. euphorbiae (anted, pp. 

 202 et seq.) entirely excluded dahlii, tithymalu maitreianica, robertsi 

 and costata as being separate species ; conspicua, Roths, and Jord., 

 comprises part of our var. lathyrus, Walk, (see p. 210); siehei, Pung., 

 has been described since this part of our work was printed ; 

 centralasiae, we have treated as a variety of euphorbiae ; nei-vosa was 

 unknown to us. We are inclined to think that conspicna, siehei and 

 centralasiae are eastern forms (i.e., varieties or local races) of H. 

 euphorbiae, but we still believe that, in the ordinary sense, dahlii, 

 tithymali, mauretanica, robertsi, nervosa and costata are entitled to 

 specific rank. The following notes, therefore, are explanatory of, or 

 supplementary to, those already published in our account of the 

 species (anted pp. 202 et seq.): 



[Page 206, to follow ab. lafitolii, Thierry-Mieg.] Styles ab. 

 restrirta, Roths, and Jordan, " Revision of the Sphing.," p. 720, pi. viii. , 

 fig. 11, <$ .— A $ in the Tring Museum has the forewing entirely tawny- 

 olive above, except a small spot at end of cell, and a series of small elongate 

 hastate or linear spots on the disc upon the veins ; fringe of hinder margin 

 buffish- white, that of distal margin clay colour; marginal band deeper brown. 

 Disc of hindwing above yellowish-red, far less bright than in ordinary euphorbiae. 

 Underside of body and wings much shaded and speckled with brown, especially the 

 wings ; forewing with very little red, hindwing yellow-red on disc. Caught on the drill 

 ground at Bamberg. Received from A. Heyne (Rothschild and Jordan).

 Staud., " Hor. Soc. Ent. Ross.," xiv., p. 297 from paralias, Nick., to 

 conspicua, Rothschild and Jordan, " Revision of Sphingidae," p. 720. 



[Page 208.] Hyles var. (an ab.) esulae, Bdv. — The name of this 

 form is changed to nigrescens, by Rothschild and Jordan (Revision of 

 the Sphingidae, p. 720). 



4. [Page 210.] Hyles var. (an spec.) lathyrus, Walk. — Roths- 

 child and Jordan {Revision of Sphingidae, pp. 720 and 727) separate the 

 synonymy that we quote, into two sections, viz. (1) that relating to 

 the Syrian, and (2) that relating to the Indian, form. The lathyrus 

 of Staudinger's Catalog, 3rd ed., p. 103, so far as it relates to the 

 Syrian form (=paralias, " Hor. Soc. Ent. Ross.," xiv., p. 297), is re- 

 named conspicua by these authors, and is treated as a form of euphorbiae, 

 whilst the Indian form [the lathyrus of Walker, Butler, and ourselves 

 {anted, p. 210) and the euphorbiae of Hampson] is treated as a variety 

 of Hyles nicaea. Rothschild and Jordan's imaginal material, on which 

 this separation is based, appears to be somewhat slight (3 $ s of 

 conspicua and 2 $ s of lathyrus), but these authors are very decided in 

 the opinion as to the accuracy of their conclusion. Even if the separation 

 be accurate we should treat conspicua as a species separate from 

 euphorbiae, as, indeed, we consider almost all Rothschild and Jordan's 

 so-called subspecies of euphorbiae, Linn., to be. Their description of 

 conspicua is as follows :
