TORTRICINA. 93 



GENUS XL HALONOTA, STEPHENS. 



Palpi slightly longer than the head. Middle joint densely clothed 

 with scales, partly enveloping the apical one. Basal joint drooping, 

 stout, pyriform, truncate ; apical slender, subcylindric, much longer 

 than the basal ; middle ascending, moderately stout, curved, thickest 

 beyond the centre ; twice as long as the apical joint. Maxillae 

 longer than the palpi. Thorax robust, ovate, sometimes crested. 

 Anterior wings : the length equals twice the width. Costa slightly 

 arched beyond the fold in the tf , and regularly so in the $ . Apex 

 obtuse. Apical margin concave ; dorsal margin slightly rounded. 

 The costal vein does not extend beyond the fold. The discoidal cell 

 proceeds two-thirds along the wing ; subcostal nervures equidistant. 

 Posterior wings : ample, acute at the apex ; apical margin concave ; 

 dorsal margin entire. Abdomen in the $ slender, and tufted at the 

 apex ; stouter and obtuse in the $ . 



Formerly a genus of much larger extent than at present, 

 owing to the structural details not being sufficiently observed, 

 although still containing many species, forming a very natural 

 group. Their dimensions are very varied, are mostly of dark 

 colours, and for the most part having a pale blotch (sometimes 

 more than one) on the dorsal margin. The larvae are chiefly, if 

 not wholly, internal feeders, living in the stems and roots of 

 herbaceous plants; they are sluggish, stout, and of various 

 colours. 



The British species are nine in number, and are thus tabu- 

 lated : 



A. Anterior wings with two distinct pale or white 



Hatches on the dorsal margin Species 1 



B. Anterior wings with one distinct pale or white 



blotch on the dorsal margin Species 2 



a. With the blotch irregularly quadrangular . . Species 2-6 



6. With the blotch slender, produced, and. angulated Species 9 



C. Anterior wings with the blotch scarcely different 



from the ground-colour of the wings .... Species 7-8 



1. bimaculana, Donovan. Alis anticis runs brunneo-strigatis ; 

 maculis duabus rotundatis stramineis (Fcem. albis) pallide fusco- 

 strigatis, quarum posticam format speculum angulo anali ; posticis 

 fusco-griseis. ^ Exp. al. 8-10 lin. 



Head and face deep umber. Eyes black. Palpi : above deep 

 umber ; at the sides rather paler, except at the apex ; beneath and 

 between obscure ochreous. Antennae deep fuscous. Thorax and 

 patagia deep umber ; the latter with the apices cream-colour. An- 

 terior wings dull; umber mixed with shades of brown, and two 

 cream-coloured blotches on the dorsal margin. The dark portion of
