2. N.E. — Scarborough (R. Lawsori). 



5. S.W. — Hebden Bridge Watercourse, 1831 {Sam. Gib- 

 sofi, February 23rd, 1832, in Loudon's Mag., 1832, v. 555). 

 Agabus guttatus Payk. Local. Inhabits clear running water. 

 I have found it dead on the South Sands at BridUngton 

 Quay in some numbers, in company with the next species. 

 No doubt the insects were brought down by the clear 

 streams, which enter the sea in that neighbourhood.

2. N.VV.— Studley {E. A. Wate /house). 

 Agabus didymus 01. Local and not plentiful.

 Agabus nebuiosus Forst. {■=bipunctatus F.). General, 

 though seldom very abundant. 



1. S.E. — Brough [E. B. Wrigglesworth) .

Agabus abbreviatus F. {=iindulatus Schr.). This elegant

 is abundant in May, and obtainable during most of the 

 year. It has also found its way into the neighbouring 

 brick-ponds on Hob Moor.

 Mag., 1831, iv. 165) ; ditto, 1856 ( W. Hey) ; (see also E. 

 M. M., May 1868, iv. 283). Hob Moor (WC.Lf.) 



Agabus unguicuiaris Thoms. Abundant in Askham Bog, 

 but not found elsewhere in Yorkshire.
