ON THE SPECIES OF EUROPEAN CItAMBI ALLIED TO 

 C. PINELLUS. 



BY GEOEGE T. BAKES. 



Judging from experience, it is not improbable that many collectors 

 in Switzerland pass over, by mistake, some of the Crambi allied to 

 pinellus. The following short description of those European species 

 which are brown or orange-brown, with a central white longitudinal 

 stripe once or twice transversely divided may, therefore, be useful. 

 (The transverse band excludes the margaritellus Sindt.furcatellus group, 

 which is reserved for another paper). 



Our group may be tabulated for convenience thus : — 



A. Longitudinal stripe divided once only. 



pauperellus, conchellus, pinellus, inytilellus. 



Hue of ground unicolorous, stripe dull cream-colour ... pauperellus. 



G-round colour more or less darkl}'^ shaded, stripe shining white... 



conchellus. 



Ground colour almost unicolorous, an oblique white curved line 

 beyond the longitudinal stripe mytilellus. 



Such curved line wanting pinellus. 



B. Longitudinal white stripe twice divided. 



myelins, speculalis, permutatellus, luctiferellus. 



Ground colour cinnamon, the two transverse bands oblique but 

 straight, with an orange shade myelins. 



With a brown shade speculalis. 



Hinder transverse band waved permutatellus. 



Ground colour dark olive-brown luctiferellus. 



PAUPERELLUS, Tr. (25 mm.). 



Fore-wings oclireous-brown, with a pale ochre or cream-coloured longitudinal 

 stripe, which is of a narrow wedge-shaped form, narrowest at the base, where it 

 starts from the centre of the wing and is continued nearly to the hind margin ; 

 beyond the middle it is divided by an oblique transverse band of the same hue as 

 the ground colour, in some specimens the hind margin of the posterior division is 

 shelved off so as to be nearly parallel with this band. The fringe is wliitish, with a 

 dark dividing line. The hind-wings are uniform brown-grey with whitish fringes, 

 having a dark dividing line as in the fore-wings. 



Head, palpi, and antennae pale ochre-brown. Thorax same colour as the upper 

 wings. Body as the hind wings. 



I have not taken this insect myself, but it is not uncommon in 

 the Jura range, and I have also had specimens sent me from Hungary.
