 type ? gave all types. In 1910, (a) type x type gave 66.G 7o ^^^ 33.3 7o ^^i'- 

 nigra; (6) nigra x nigrra gave 92 "/^ nij/ra and 8 °/q type ; and (c) nigra x nigra 

 gave 96 7^ nigra and 4 "/^ type ; while in 1911, (a) type x type gave all type ; 

 (6) nigra, g x type 9 gave all /lif/ra ; (ej nigra x ?n(;ra gave 95.7 °/c nigra and 

 4.3 °/q type ; and (d) a second experiment of the same gave 70.5 °\^ nigra and 

 29.5 7o type. In 1910, moths from the broods (a.) and (c) were used for the cross

NOTES ON THE BRITISH SPECIES OF L0NGITARSU8, Late. 



(A GENUS OF COLEOPTERA)

Food plants. — The food plant of this species is practically 

 unknown, although Bedel gives " Lithospermum officinale d'apres 

 H. Brisout." One of us has swept it from herbage in which Go7i- 

 volvulus arvensis was the most abundant plant, near Malvern. 



Its range in this country is quite uncertain. It undoubtedly 

 occurs, but apparently very rarely, in the London district, but other 

 records, although fairly numerous, are entirely uni*eliable, and it is 

 probably often cast away as one of the commoner species which 

 it resembles. 



Var. — ruhenticollis. All. (Mon. p. 392), is simply a form with a 

 reddish thorax, and bears precisely the same relation to the type as 

 V. fuscicolKs, Steph., does to L. suturellus, Duft.

In form and coloration very similar to L. suturalis, but much smaller. 

 Head shining black. Antennse : black with first four joints testaceous. Thorax 

 slightly transverse, bordered, black, with a faint brassy reflection, distinctly
