Order Lepidoptera. Fam. Noctuidje. 



Type of the Genus, Noctua glyphica Lirm. 

 EucLiDiA Och., Huh., Curt. — Phytometra Haw. — Noctua Linn.,Goda. 

 Antennce inserted on the crown of the head, moderately long, 

 setaceous, clothed with long scales above, densely ciliated be- 

 neath in the male (1). 



MaxiUcB as long as the antennae, stout and spiral (3). 

 Labial palpi recurved as high as the crown of the head (4), 

 stout, attenuated, clothed with short scales, the apical joint 

 distinct ; triarticulate (4 a), basal joint stout elongated, nar- 

 rowed and curved at the base, 2nd scarcely twice as long, 

 curved at the base and sHghtly attenuated, 3rd slender and co- 

 nical, shorter than the 1st. 

 Head small, subtrigonate : eyes rather small and siibglohose : ocelli 

 distinct. Thorax not very stout and rather hairy, as well as the 

 Abdomen, tvhich is short obtuse and tufted at the apex in the male, 

 stout and conical in the female. Wings slightly defiexed and forming 

 a triangle in repose : superior rather short and irregularly trigonate : 

 inferior ovate-trigonate. Tibiae, anterior very short, ivith an internal 

 spine, intermediate furnished with several acute spines on the inside 

 (8 *) and terminated by a very long and a shorter spur ; hinder tibia 

 not much longer but stouter and hairy outside, with a very long and 

 a short spur at the apex and a similar pair a little above them (8 f) : 

 tarsi longer than the tibicE, especially the anterior, spiny, b-jointed,

The Caterpillars of this group form a beautiful connecting 

 link from the looping Noctuidas to the Geometridae. It will 

 be remembered that the larvse of Catocala and Brepha have 16 

 feet, whilst those of Euclidia have but 14, not 16 as stated by 

 Mr. Stephens. The structure of the intermediate tibife is dif- 

 ferent to any others that I have examined, and seems hitherto 

 to have passed unnoticed ; the outside is rough and the inside 

 is furnished with series of spines as represented at fig. 8#. 



The two pretty species of Eiiclidia inhabiting Britain prefer 

 chalky districts ; they fly in the sunshine during the middle of 

 the day.
