PHYCITIDA-l—RHODOPH.KA. 13 



I tliinif that we have uo definite knowledge of the larva or 

 pupa. Sorhageu says that the larva feeds along with that 

 of A. roiuiocidla, in a silken tube on oak leaves ; and similar 

 statements are made by others ; but it is not clear that this 

 species was intended. Certainly more full information is 

 desirable. 



An excessively rare species here ; nearly all the references 

 belonging to the previous. I have a specimen in fine con- 

 dition, which was taken in a salt-marsh near Portsmouth, 

 Hants, many years ago, by Mr. Henry MoncreafF, and which 

 agrees most accurately with German specimens ; two more 

 were taken in Suffolk by Dr. Wheeler, but these I have not 

 seen recently, and am not absolutely certain that they repre- 

 sent the present species. This is the extent of the present 

 knowledge of the species in these Islands— further observa- 

 tions are most desirable ! Abroad it is a well known and 

 widely distributed species, in Central and Southern Europe. 



Genus 1 ] . RHODOPHiEA. 



Antenna} of the male simple, without basal thickening or 

 tuft, but bent back ; palpi small, very slender, up-curved, the 

 maxillary filiform but hardly perceptible ; fore wings elon- 

 gated, moderately broad, the cell rather narrow from arching 

 of the median nervure ; hind wings ample, the cell small 

 and pointed ; veins 7 and 8 coalescing. 



We have three species, rather similar. 



A. First line of fore wings perpendicular, white. 



R. marmorea. 

 A'. First line rather oblique, branched, enclosing a red 



dorsal triangle. e. advcnella. 



A?. First line more oblique, single, the wing clouded with 



silvery grey. ^. mavella. 



1. R. advenella, Z^.— Expanse f to | inch (18-22 

 mm.). Fore wings elongated but rather broad, shining
