Insects in Great Britain. 
249 
CARYOPHYLLACEAE : 33. Lychnis diurna Sibth. [Class F, 
Lit. 1, 2, 4, 9, 11, 14, 117 b, 288 b.] Common in the district, 
but its flowering season was getting over. 
Visitors. Hymenoptera. Aculeata : Acutilingues : ( 1 ) Bombus ter- 
restris L., s. h. freq. 31 . 8 to 13 . 9 . 94 . Diptera. Syrphidae : ( 2 ) 
Platychirus albimanus F., f. p. Cl. 31 . 8 . 94 , and so only going to 
male flowers. 
As the above observations are all made at one period and 
place, and cover the important flowers of the local flora, it 
will be best to sum them up independently of those which 
follow. 
Summing up first of all the total number of visits received 
by each class of flower, we get the following table : —

Next, adopting the percentage method, and using as a refer- 
ence line the percentage number of visits of all insects to each 
class of flower (see 341 b), we get this table : —
