84 Mr. F. P. Pascoe on the Colydiidee 
the eyes; prothorax with its two lobes not deeply divided, and only 
slightly separated behind from the rest of the prothorax, an irregular 
smooth cavity on each side anteriorly ; elytra seriate-granulate, setose ; 
body beneath and legs black, coarsely punctured, and with scattered stiff 
hairs; antenne black. Length 3 lines. 
Extremely like Distaphyla mammillaris, but with lobes less deeply 
separated from the prothorax, and scarcely any trace of the triangular 
space behind them, the sides of the prothorax anteriorly with a large 
smooth excavation which does not exist in the former species, al- 
though there is a sort of break in the much larger tubercles, accom- 
panied with correspondingly deeper intervals between them, as if 
Nature only just contemplated the step she afterwards takes. 
Distaphyla speculifera. 
D. subcylindrica, picea ; prothorace linea inter lobos et spatio triangulari 
postico leevissimis, nitidis.

Subcylindrical, pitchy, setosely tubercular; head with a deep trans- 
verse hollow between the eyes ; prothorax with its lobes separated from 
each other by a smooth shining line, which is also continued round to 
their sides and behind them, and a large but rather narrowly triangular 
very smooth and glossy space extending back to within a third of the 
total length of the prothorax, beneath this on each side a large trian- 
gular excavation nearly filled in with two irregular protuberances ; 
elytra seriate-granulate, setose ; body beneath rugosely punctate, covered 
with short stiff hairs; antennze dark brown. Length 3 lines, 
The remarkable triangular space behind the prothoracic lobes, 
smooth and glossy as a mirror, will at once distinguish this species. 
The lateral impression, of a triangular form with the base anterior, 
occupies nearly the whole length of the side, and is nearly filled in 
by two irregular protuberances, the anterior largest and glossy, the 
posterior opake.

TRenyTHA. 
Caput exsertum, subquadratum, convexum. Antenne basi tectie, clava 
triarticulata. Prothorax elongatus, subcylindricus, lateribus rectis sub- 
marginatis. Hlytra parallela, costata, apice declivia. Zbve subtrigo- 
natie, calcarate. Zarsi graciles, articulo basali subelongato. Corpus 
subcylindricum. 
My specimen being unique, I am unable, unfortunately, to say 
anything of the trophi of this genus. It appears to be very closely
