132 Mr. R. M‘Lachlan’s Monograph of the 
et Spec. Trichop. pt. 2, p. 223, 3 (1859)?; T. flavipes, 
Hag. (*) Stett. Zeit. 1860, p. 282, 1. 
Antenne yellowish, closely annulated with fuscous. Head and 
mesothorax clothed with golden-yellow hairs. Palpi fuscous. 
Anterior wings greyish, subhyaline, clothed with very short yel- 
lowish pubescence; fringes greyish-yellow ; neuration distinct, 
fuscous. Posterior wings paler, with longer yellowish-grey 
fringes. Legs yellowish. Abdomen conspicuously ochreous when 
alive, brown after death. In the male there is a short fleshy lobe 
from the middle of the upper margin of the last segment; on each 
side of this lobe are the needle-shaped testaceous app. intermed. ; 
app. sup. long, finger-shaped, curved and hairy, yellow; app. inf. 
bisarticulate, the basal joint large, ovate, with a sharp spine on 
the upper margin, apical joint smaller, deeply bifid, the two di- 
visions acute at the apex; in dead examples the spine on the first 
and the two forks of the apical joint are seldom visible, the 
latter being usually pressed closely together and apparently inse- 
parable. In the female the abdomen terminates in a short trian- 
gular ovipositor. 
Expanse of fore-wings 7—9 lines. 
Common in summer and early autumn about streams. 
I cannot separate the various species named by Stephens, and 
consider them all to belong to one. 7. annulicornis, given by Dr. 
Hagen as distinct, seems to be only a small female of this. 
The species of this genus shew the necessity of making careful 
examinations of living specimens, as the parts of the appendices 
are far less distinguishable after death. 
2. Tinodes pusilla, M‘Lachlan. (PI. XIII. fig. 15, app.) 
Tinodes pusillus, Curt. (*) Phil. Mag. p. 216, 4 (1834, not de- 
scribed) ; M‘Lach. Ent. Ann. 1862, p. 37. 
Antenne fuscous, indistinctly annulated with yellow. Head 
thickly clothed with yellow hairs. Palpi fuscous. Mesothorax 
dark fuscous, with a few brownish-yellow hairs. Anterior wings 
broader at the apex than in the last species; hairy clothing much 
denser, greyish-yellow, with concolorous fringes ; neuration very 
indistinct. Posterior wings subhyaline, iridescent, with yellowish 
fringes. Legs greyish-yellow. Abdomen brown (in dead ex- 
amples). In the male there is a long fleshy lobe from the middle 
of the upper margin of the last segment, beneath which lie the 
needle-shaped app. intermed., the points only being visible; app. 
sup. very long, finger-shaped, slightly dilated at the base, very
