PHYMATA. 53 
One example. Differs from all the other Central-American species of the genus in 
the strongly trisinuate sides of the pronotum, the four teeth thus formed being about 
equally prominent. In the annulate legs it approaches P. annulipes and P. noualhieri, 
but differs from both in the much less widened connexivum. The insect is unknown 
to Herr Handlirsch, after whom I have much pleasure in naming it.

Numerous examples of this species have been found in Chiriqui, two only in Tabasco, 
these latter having the frontal process more obtuse at the tip. Lasily distinguishable 
from the other Central-American species by the long head, the acute lateral angles of 
the pronotum, the strongly and acutely dilated abdomen, the fourth segment of which 
is produced laterally into a long, acute tooth, and comparatively small size. ‘The 
eighteen specimens obtained show very little variation in colour. I have not seen 
it from Guatemala. An example from Bugaba is figured.

Hab. Mexico (coll. Signoret 173, in Mus. Vind. Ces.: ¢ ). 
Easily distinguishable from the allied forms with the abdomen parallel at the base 
by the exceedingly elongate apical joint of- the antenne in the male. The head has 
two prominent conical tubercles on the disc and a bilobed frontal process. The 
anterior tooth of the lateral angles of the pronotum is subvertical and conical in shape. 
The connexivum is broadly and abruptly dilated beyond the middle, and obliquely 
narrowed thence to the apex; the segments 1-3 have each a conspicuous tuberculiform 
prominence at the outer apical angle (a character not mentioned by Stal), the first 
segment being also thickened and dilated at the outer anterior angle; the fourth 
segment is strongly foliaceous, with two prominent teeth, the outer apical angle also 
being produced into a tooth; the fifth segment is dilated at each outer angle. The
