HESPERIA. 57!) 
Hesperia obertliuri. (riate XLI. fig. 5, 6 .) 
Stjr'ichthus oberthiln, Leech, Entomologist, xxiv., Suppl. p. 59 (June 1891). 
Syrichthus delavayi, Obertliiir, Etud. d'Entoni. xv. p. 20 (July nee June, 1891). 
Closel)' allied to Hesperia maculafa, Brem., with which it agrees almost exactly in colour and 
ornamentation of upper surface, hut the outer macular hand is less augulated. The under 
surface of secoiuhiries is olive-green or grey, with white basal and central bands formed of 
connected sjjots, which in the central series are of various shapes — one of these below costa 
is bar-shaped : between the bands the costa is white, with a round spot below of the same 
colour ; the submarginal line is also white, waved, and interrupted. 
Expanse 33-35 millim. 
" En effet ses caracteres distinctifs consistent dans I'acoentuation des taches blanches en dessus, 
dans un seul changement, quant a la disposition generale de ces taches qui sont en serie plus 
droite et-moins echelonnee ; et en dessons dans I'accentuation egalement plus grande de tous 
les dessins et taches qui sont plus nets, avec des contours tres arretes et comme circonscrits 
par un trait noinUre extremement fin. La couleur generale des taches en dessous est 
grisatre, sans tendance au rougeatre, comme cela se remarque dans le bieti du Yunnan." 
(Oherth'ur, I.e.) 
A good series from Wa-ssu-kow, taken at an elevation of 5000 feet in ^lay 
and June. 
M. Oberthiir considers this to be a local form of *S'. lieti, but both species 
occur together at Wa-ssu-kow. Obertliuri may be distinguished from bieti 
by its brown rather than black coloration, and by the more complete, curved, 
and more angulated bauds of secondaries ; the under surface also exiiibits 
important differences. 
Hesperia alveus. 
Papilio alveus, Hiibner, Eur. Schmett. i. figs. 461— 1G3 (1798-1803). 
Hesperia alveus, Rambur, Faun. And. pi. viii. fig. Ill (1839). 
Syrichthus alveus, Lang, Butt. Eur. p. 311, pi. Ixxix. fig. ] (1881). 
" Expands from 1 to 1-10 in. Brown. Fore wings with a white discal spot and a submarginal 
row ; there is a small white dot near the centre of the inner margin and the usual tripartite 
costal spot. Hind wings as in cartlutmi, but even less distinctly marked; fringes brown and 
white. Underside : fore wings grey with white spots, as above, but suffused ; hind margin 
brownish or greenish. Hind wing white, with central and submarginal greenish hands, 
irregular in shape ; there is a basal spot of the same colour as the bands." {Lanrj, I.e.) 
This appears to be a scarce species in China. I received three specimens 
from How-kow, where they were taken at an elevation of 10,000 feet. 
M. Grum-Grshimailo sent me a specimen from Koko-noor which agrees 
exactly with these examples, and I have individuals in my European series
