structure, and, excepting the density of alar infumescence, the 
colours are very constant; I have seen examples varying from : 
body 14 and terebra 35 mm. in length, to others with body, 
19 mm. and terebra fully 60 mm. in length. The National 
Collection is somewhat rich in this South American species :— 
Chili (Bartlett Calvert; in 1856 by T. Edmonds; and in 1875 
by Edwyn C. Reed); Valdivia, Corral or Conal in 1898 (Cameron) ; 
South Chili, Maquehue, Temuco, January, 1906 (R. M. Middle- 
ton); Santiago in 1869 (Reed); Patagonia, Volcan del Lago 
Xanco, two in 1908 (Chubut) ; Terra del Fuego, Rio McClelland 
on December 30th, 1904, and Nose Peak on January 15th and 
18th, 1905 (R. Crawshay); and Haliday’s type, labelled ‘‘ Cryptus 
bellicosus”’ by him, presented by the Linnean Society in 1863.

I have not seen this Californian species. 
NOTES ON EUROPEAN HESPERIDS. 
By W. G. Sueupon, F.E.S. 
A year or two ago, until the researches of Dr. Reverdin 
threw a flood of light on certain species in this group, those of 
us who were interested in the genus labelled our specimens with 
doubt and trembling, and described them, if we said anything 
about them in print, as examples of species which they almost 
invariably had no pretence to belong to. Consequently, reliable 
data for these species are at present non-existent, except those 
contained in Dr. Reverdin’s papers on the subject in the Bulletin 
of the Geneva Society. 
My friend Mr. A. L. Rayward has most kindly, recently, 
made preparations of all the doubtful specimens of the alveus 
group which I have met with in my various wanderings in 
different parts of Kurope during the past twelve years, and as 
the species those specimens belong to can now be with certainty 
determined, I append a list of localities in which they were 
found, in the case of each species, and the actual dates on which 
the specimens were taken :— 
Hesperia alveus.—I have specimens from Simplon Kulm, 
July 24th and 25th, 1908. Berisal, July 22nd and 23rd, 1903. 
The Laquinthal, July 26th, 1903. 
H. serratule.—Buda Pest, May 22nd, 1910. Berisal, July 
7th, 1902. Albarracin, June 18th and 19th, 1913. 
H. onopordi.—Albarracin, May 26th to June 6th, 1913. 
Ronda, April 19th, 1908. Hyeres, April 11th, 1904, and May 
13th, 1905. Digne, July 13th, 1904.
