SEinCOSTOMlD.E. NOTIDOEIA. 185 



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



note* will show that his name must fall, 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, &c. 



Genus XX,— NOTIDOBIAf mihu 



AnienncB 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 slender, 

 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 ; tibiw 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 

 K)f Phryganea, L. {Fhryganea 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 which, 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 ; antennje between 

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

 thicker than the rest."— Kirby and Sp. Inf. iii. p. 489. (1826.) 



In the 2iid 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.
