species is "somewhat rare." Van der Wulp (Diptera Neerlandica, 

 Eerste Deel, 1877, p. 325) also says that it " appears to be rare," 

 adding that the ? has been taken in August at Brummen, near Zutphen, 

 and in the dunes near Vogelenzang, not far from Haarlem.

NOTES ON COCCIDS FROM KENT. 

 BY E. ERNEST GKEEN, F.E.S. 



DiASPis Eos^, Bouche. 

 In a note on this insect, published in the Ent. Mo. Mag., June, 

 1887, it is intimated that the species is somewhat rare in England. 

 In reply to a query on the subject, Mr. J. AV. Douglas informs me 

 that he has had no notice of its occurrence since the date of that 

 article. I have, however, received specimens from Mr. R. Newstead, 

 taken at Chester in 1892. Its appearance this year in the Maidstone 

 district may be worthy of notice. I find a large colony of the insects 

 located on the stems of a wild rose tree in a garden at Bearsted, and 

 another colony on a cultivated rose (^Gloire de Dijon) trained against 

 a wall in the same garden. In each case 

 the scales are principally confined to the old 

 stems. The ? scales contained, in July and 

 August, adult insects of the normal form 

 (fig. 1) and numerous eggs. In the speci- 

 mens under examination the median pair of 

 pygidial lobes only are conspicuous, the 

 others being almost completely concealed 

 within the margin of the body. 1 find the 

 ^"^ *' number of orifices in the grouped glands to 



vary considerably in different specimens ; nor are they generally 

 symmetrical. The formulae for six specimens examined are as 

 follows, viz. : — 



(.% 30) (l8 22) (3.5 40) (32 29) (24 25) (27 29) 



\40 27/ \14 2C/ \3fi 35/ \29 29/ \25 26/ \25 28/ 



Other six specimens from Chester give the following numbers : — 



(24 17) (24 22) (21 27) (24 25) (.34 30 ) (23 26) 



\28 24/ \26 2"/ \27 24/ \30 30/ VSO 20/ \26 24' 



The lateral groups are almost continuous ; but the divisions can 

 be determined by following the contour lines that enclose each group.
