sometimes a dark apical streak. Hindwings grey, terminally

England to York, E. Ireland, uncommon ; C. and S. Europe, 

 C. and S. Asia, Africa, N. America; 7, 9-5. Larva rather 

 stout, greenish; incisions reddish or yellowish; dorsal and

 diamonds outlined with brown, including a black mark ; spira- 

 cular line blackish, interrupted : on Polygonvm, Agrimonia, 

 etc. ; 5, 6, 8. 



38. H. polygrammata, Bkh. (conjunctaria, Ld.) 22-24 mm. 

 Forewings pale greyish -ochreous, with straight dark fuscous 

 striae, sharply angulated near costa except posteriorly ; third 

 fascia suffused with fuscous except towards costa, fourth on 

 upper half, sixth except above an oblique apical streak ; a 

 black discal dot, often in a pale ring. Hindwings pale greyish- 

 ochreous, with straight rather dark fuscous striae, posteriorly 

 curved. 



Cambridge, Gloucester, very local (other records doubtful) ; 

 C. Europe ; 4, 8. Larva on Galium ? 



39. H. lapidata, Hb. 26-28 mm. Forewings somewhat 

 elongate, pale brownish, with ashy - fuscous striae ; edges 

 of median band darker, anterior curved, posterior twice 

 subsinuate, remotely followed by a similar darker stria; a 

 darker central twice sinuate stria ; a fuscous discal dot ; a

17. PBLURGA, Hb. 



Face with hardly projecting scales. Antennae in $ shortly 

 ciliated. Palpi rough -scaled. Thorax with horny rounded 

 anterior dorsal prominence. Forewings : areole double. Hind- 

 wings : 8 anastomosing with cell to beyond middle. 



The single species is probably correlated to early forms of 

 Hydriomena.
