A HISTORY OF HERTFORDSHIRE 



HYDRIOMENID./E (continued) 



Hydriomena miata, L. St. Albans and Harpen- 

 den (A. E. G.) ; Sandridge (Griffith) ; 

 Hitchin (Durrant) ; Haileybury (Bow- 

 yer) ; East Barnet (Gillum) ; Bricket 

 Wood (Cutts) ; Watford (Heaton, 

 Wigg) ; Wilstone (Elliman) ; Tring 

 (Goodson) ; Cheshunt (Boyd) 



In most of the districts this insect 

 is fairly common at ' light,' but Mr. 

 Boyd has only taken one specimen 

 in his locality 



sordidata, F. (elutata, Hb.). St, Albans 



and Bamville Wood Farm, Harpenden 

 Common (A. E. G.) ; Sandridge 

 (Griffith) ; Hitchin (Durrant) ; 

 Haileybury (Bowyer) ; East Barnet 

 (Gillum) ; Oxhey Wood and Bushey 

 (Cutts) ; Watford (Spencer, Heaton, 

 Wigg) ; Bushey Heath (Barraud) ; 

 Tring (Elliman) ; Cheshunt (Boyd) 



A fairly common and very variable 

 species 



trifasciata, Bkh. (impluviata, Hb. ; 



literata, Don. ; ruberata, Frr.). 

 Haileybury (Bowyer) ; Watford 

 (Heaton) 



A rare species. The Haileybury 

 School List records the capture of 

 one specimen of trifasciata and one 

 of ruberata 



truncata, Hufn. (russata, Bkh. ; im- 



manata, Hw.). St. Albans, Hedges 

 Farm, Bricket Wood, Welwyn and 

 Bamville Wood Farm, Harpenden 

 Common (A. E. G.) ; Sandridge

 Heath (Barraud) ; Oxhey (H. Row- 

 land-Brown) ; Tring (Elliman) ; 

 Cheshunt (Boyd) 



The two forms russata and im- 

 manata are regarded by many ento- 

 mologists as distinct species, and 

 most of the Hertfordshire observers 

 have treated them as such. In this 

 list no attempt has been made to 

 discriminate between them. Both 

 forms appear to be fairly well dis- 

 tributed through the county and 

 both are common 



silaceata, Hb. Sandridge (Griffith) ;

 (Spencer, Heaton, Wigg) 

 Not common 



corylata, Thnb. St. Albans (A. E. G.);
