Scape of antenne pale yellow beneath; the flagellum 
black, the apical half brownish beneath. Face, clypeus, and 
labrum smooth and shining, the middle sparsely and minutely 
punctured. Mandibles black towards the apex. Front and 
vertex smooth. Pro- and mesothorax smooth and shining ; 
the scutellum is yellow, except in the middle at the base. 
The base, upper part, and centre of the median segment 
smooth and shining, the rest rugosely punctured ;_ the posterior 
median area becomes gradually narrowed from the base to the 
apex and is keeled down the middle. Pro- and mesopleuree 
smooth and shining; the tubercles are large and pale yellow, 
and there is a yellow mark below them; the upper half of the 
metapleure is smooth, the rest closely and distinctly punc- 
tured. Legs coloured like the body, except that the four 
anterior are more or less pale yellow in front; the hinder 
tarsi are black towards the apex, as are also the hinder tibie.

LXVIII.—Rhynchotal Notes.—X. Heteroptera: 
Fam. Lygeide. By W. L. Distant. 
THE present contribution relates to the subfamily Lygein 
as contained in the collection of the British Museum, with 
a revision of Walker’s determinations in this group. All 
further study strengthens the opinion that when Walker’s 
types are obtainable his species (if valid) should stand; but 
his descriptions are often so imperfect—as they are especially 
in this family—that where the types are not to be found such 
descriptions should be considered as non-existent, a course 
not necessarily harsh when the vast synonymy already created 
is realized and the loose location of the species is remembered.
