It has only been found in Ireland; common, according 
to Haliday, in dry sea-weed on the coast.

Alysia fuscipes, Hal., Ent. Mag., v., 217, 2 (not of 
Nees).

@. Palpi shorter than in the preceding, as also are the antenne 
and the general form. Legs blackish. Abdomen suborbicular, 
depressed. Terebra hardly visible. g unknown. Length, 2

No more is said of this species, except that it resembles 
fucicola, with which it was taken rarely ; found also once 
in the London district by Walker. The synonymy given 
by Haliday in the Ent. Mag. is erroneous ; Alysia fuscipes, 
Nees, belongs to Genus x1. Aphereta. To avoid confusion, 
Forster changed the name of the present insect to 
Halidaii, and also founded upon it his uncharacterised 
genus Phexnolyta. 
iv. Tracayusa, Ruthe. 
Ruthe, Stett. Zeit. 1854, p. 352. 
Palpi of ordinary length, maxillary with 6, labial with 4 joints. 
Two first joints of the flagellum of nearly equal length. Meta- 
thorax not carinated. Radial areolet cultriform, narrow, reaching 
the tip of the wing; radial nervure straight ; 2nd abscissa shorter 
than the 1st intercubital nervure ; 2nd cubital areolet twice as 
broad as its length, measured along the cubital nervure ; anal 
nervure not interstitial ; stigma large, oblong, obtuse at both ends, 
emitting the radial nervure from its outer half. Second abdo- 
minal segment punctulate, dull, with a transverse impression in the 
middle. .'lerebra hardly exserted. 
The elegant species which forms this genus seems 
rightly separated from all others; its form is more 
elongate, and resembles, as Haliday has remarked, that 
of the Cyclostomous genus Colastes; his observation 
refers, no doubt, to Xenarcha lustrator (Ent. Tr., 1885, 
p- 50). The name Trachyusa appeared to Forster too
