H. pomatia, L. Birdlip Wood ; Witcombe ; Miserdine ; 

 Colesbourne ; Rendcomb (Jones) ; Chedworth ; Longfords. 



H. nemoralis, L. Hedgerows and gardens — common. 



H. nemoralis, var. conica, Pascal. Slad Road, Stroud. 



H. nemoralis, var. compressa, Terver. Slad Road, Stroud 



H. nemoralis, var. bimarginata, Moquin-Tandon. Generally 

 found with the type in Stroud district, and almost equally 

 abundant. 



H. nemoralis, var. rubella, Moquin-Tandon. 



H. nemoralis, var. libellula, Risso. 



These two so-called varieties commonly occur with the 

 type, that is, the five-banded form. They are also frequently 

 found in colonies on the shady banks of disused quarries on the 

 Hills where the type very rarely occurs. 



H. nemoralis, var. castanea, Moquin-Tandon. Most com- 

 monly found in gardens. 



H. hortensis, Miiller. [H. nemoralis vars hortensis and 

 hyhrida] . Hedgerows and clumps of brambles and rank weeds 

 in disused quarries — generally distributed. Jones states that 

 this form, which he considered a variety of H. nemoralis, — was 

 abundant with that species. This, however, does not agree 

 with my observations. Occasionally they occur in association, 

 but it is the exception rather than the rule. 



H. hortensis, var. roseolabiata, Taylor. Found occasionally 

 with the type. 



H. hortensis, var. fuscolabiata. Von Martens. This variety 

 is that which is referred to in Jones' paper as ' H. nemoralis var. 

 hybrida.' Abundant at Tortworth (Jones) ; Thrupp, near 

 Stroud — very scarce. 



H. hortensis, var. luteolabiata, L. E. Adams. Frocester Hill. 

 Not common. 



H. hortensis, var. albina, Moquin-Tandon. A rather local 

 variety but common by the roadside from Salmons-Spring 

 Brewery to Rock Mill, Stroud. 



H. hortensis, var. lutea, Moquin-Tandon. Common with 

 the type. 



H. hortensis, var. arenicola, Macgillivray. With the var. 

 albina, as above, and occasionally wherever the type is 

 found.
