Capside. 307 
BYRSOPTERA, Spin. 
Quite distinct from any of the allied genera, and more 
closely resembling Mecomma, from which, however, the 
hook-like nerve of the wing-cell will distinguish it at once, 
6 macropterous; ?, as far as I know, always bracypterous. 
6 in form ike a narrow Mecomma; head nearly as wide 
as the base of the pronotum, antennze slender, rostrum 
reaching to the posterior cox; pronotum with the sides 
and base sinuate ; elytra elongate, parallel-sided. 9 with 
the pronotum somewhat cylindrical, its sides rounded in 
front and only slightly divergent posteriorly ; elytra in one 
piece, very convex, widest posteriorly, their hind margin 
rounded; tibiz in both sexes with very fine spines. 
B. rufifrons, Mall.—Black-brown, clothed with very 
fine pale hairs, elytra paler in the ¢, head red in the 9. 
Antenne with the first and second joints black in the 3, 
the apex of the former sometimes paler, second in the 
female pale, with the extreme base and apex widely black, 
third and fourth joints very slender and pale in both sexes ; 
& with the cuneus of the elytra pale, elytra in the ? not 
quite covering the very shining abdomen, three times the 
width of the pronotum in their widest part ; legs very pale 
testaceous in both sexes. 
L. 44 mm. ¢, 34 mm. 9. 
By sweeping, generally distributed in the South of 
England. 
PHYLUS, Hahn. 
Macropterous in both sexes, rather flat and parallel-sided, 
eyes large, head not nearly so wide as the base of the pro- 
notum, second joint of the antennze subequal to the third 
and fourth together ; pronotum trapezoidal, sides straight, 
base slightly sinuate ; elytra elongate, more than three times 
as long as wide; legs slender, tibize with fine spines. 
We have three British species of the five that occur in 
Europe, ete.
