TOLANIA OBTUSA. 
(Plate LX. figs. 3, 3a, 3b.) 
Fowl. l.c. p. 166, PI. X. fig. 14. 
Head wide between the eyes, and finely striated. The suprahumerals, if visible, 
are suppressed or almost aborted. Colour concolorus brown. Posterior horn very short, 
much shorter than the abdomen. Tegmina fusco-hyaline, with the areas somewhat 
variable as to their shapes. Legs short and spotted. 
Size, 7x4 mm. 
Habitat .—Vera Paz, Guatemala, Panama. 
TOLANIA OPPONENT, Walker.

Canon Fowler notes that there are forty examples of this species in the B.C.A. 
collection, which generally show their inconstancy as to the amount of suppression of 
the suprahumerals. My figure shows this deficiency markedly. The legs are 
ciliated. 
Size, 6x3 mm. 
Habitat .—-Vera Paz, Panama. 
From the Fowler Collection. 
Before closing the diagnosis of species of this monograph, it may be noted that 
there is still an abundance of material which has yet to be worked over. There is 
a charm in the belief, and some truth in the idea of simplicity, and some will 
think that an error has been committed by the author in proposing so many new 
genera for this group of insects. But the above unworked material chiefly stands 
under the indefinite old genus Centrotus, and thus it requires restriction. There 
are a few species which do not seem to fall well under the genera here proposed, and 
these are figured as an addendum. Some examples which may be included in the 
genus Centrotus are diagnosed as such in their series, although their characters are 
drawn out of place on the last Plate LX. 
Genus : TAURIONA OBESUM, n.g. and n.s. 
(Plate LX. fig. 9.) 
Large, very robust in form. Metopidium high, and surmounted by strong, 
acute, and rather refiexed suprahumerals. Pronotum broad, and covering the 
scutellum. Head yellow. Posterior horn not narrowed suddenly, but thinning
