SERICOSTOMIB.E. — NOTtDOBlA. 185 



followed Mr. Haliday in naming this species after Latreille ; but the following 

 note* will show that his name must fallj it having been described long 

 since in Kirby and Spence. 



Found in the New Forest, about Brockenhurst, in June and July ; 

 also in the west of England, in South Wales, near Carlisle, in 

 Scotland^, &g. 



Genus XX.— NOTIDOBIAf mihi. 



Antennw much shorter than the wings, very robust, especially in the males, 

 in which sex they are somewhat serrated within; the basal joint very 

 slightly elongate, but robust and a little pilose : maxillary palpi short, 

 somewhat divaricating and pilose in the males; longer and more slenderj 

 less pilose in the females, with the terminal joint elongate- ovate ; labial 

 slender : head small, pilose : eyes large, subglobose : thorax stoutish : wings 

 rather narrow, short, anterior narrowed at the base, rounded at the apex ; 

 all with a small ovate-triangular areolet towards the hinder margin, 

 adjoining to which is a waved series of transverse nervures : abdomen short, 

 robust and obtuse : legs short, stoutish; tibice all armed with a longish pair 

 of spurs at the tip, the intermediate and posterior each with a second pair 

 below the middle, lowest in the latter. 



The short incrassated basal joint of the antennae of this genus, 



* " But the animal distinguished by the most remarkable cheeks is a species 

 of Phryganea, L. {Phryganea personata, Spence); for from this point projects 

 a spoon-shaped process, which curves upwards, and uniting with that of the 

 other cheek, forms an ample mask before the face, the anterior and upper 

 margins of v^hich, in the insect's natural state, are closely united ; and the 

 posterior part, being applied to the anterior part of the eye, causes the face to 

 appear much swoln. It looks as if it was a single piece ; but, upon pressing 

 the thorax, it opens, both above and in front, into two parts, each convex 

 without and hollow within, and each having attached to its inside a yellow 

 tuft of hair resembling a feather." 



To this account the following note is appended : — 



" This insect was taken both at Matlock and Exmouth. The body and 

 thighs are of a light brown, wings testaceous, legs pale ; antennae between 

 setaceous and filiform, two-thirds the length of the body ; first joint not much 

 thicker than the rest.'' — Kirby and Sp. Int. in. p. 489. (1826.) 



In the 2nd edition of this vol. p. 488 (published in 1830) the insect bears the 

 name Prosoponia Spencii, as above given; the generic name being adopted 

 from my Catalogue, which appeared in July 1829.
