230 HETEROMERA. 
8. Goniadera oculata. (Tab. X. fig. 12.) 
Reddish-brown, shining, clothed with widely scattered erect hairs. Head broadly and transversely excavate 
in front, very irregularly punctured (the concave portion closely and more finely, the rest very sparingly), 
the intraocular space with four or five impressions only in the middle, the eyes comparatively very 
large and coarsely faceted; antenna, the two basal joints excepted, closely punctured and dull; 
prothorax about as long as broad, rather flat, the sides expanded and broadly and subangularly 
extended before the middle, thence narrowing and sinuous to the base, the anterior angles very broad. 
and rounded and extending forwards, the hind angles distinct and obliquely truncate, the surface 
very sparingly and irregularly punctured, the punctures not very coarse and more numerous towards 
the base ; elytra broad, rather depressed on the disc, narrowly and regularly costate from the base to the 
apex, the sixth interstice well defined outwardly by a sharp ridge extending from the shoulder almost to 
the apex, the interstices each with two rows of moderately coarse impressions ; beneath shining, sparingly 
and finely punctured along the sides and anterior margins of the ventral segments. 
Length 18 millim. 
Hab. Nicaragua, Chontales (Belt). 
One example. The comparatively very large eyes, the closely punctured antenne, the 
short transverse excavation on the head, the dilated lateral margins of the thorax, and 
the regularly and narrowly costate elytra are characteristic of this insect. 
4. Goniadera nicaraguensis. (Tab. X. fig. 13.) 
Black, shining, clothed with widely scattered erect hairs. Head with numerous coarse scattered punctures, 
transversely excavate in front ; prothorax rather broader than long, comparatively narrow, the sides angu- 
larly extended before the middle, thence narrowing slightly to the base, the anterior angles very prominent 
and rather broadly extending forwards, the hind angles obtuse and obliquely truncate, the surface with 
scattered very coarse irregular punctures which are coarser than those upon the head; scutellum almost 
smooth ; elytra with numerous interrupted rows of short longitudinal smooth elevations (the elevations 
not clearly defined towards the suture, except posteriorly, and shorter, more numerous, and more conical in 
form outwardly); beneath shining, the metasternum and ventral surface with fine widely scattered shallow 
punctures, the ventral segments at the sides with scattered coarse shallow impressions. 
Length 134 millim. 
Hab. Nicaragua, Chontales (Janson). 
One example. This species will be identified by the very coarsely sculptured upper 
surface, the numerous interrupted rows of short longitudinal elevations on the elytra, 
and the comparatively narrow thorax. 
5. Goniadera pilosa. (Tab. X. fig. 14.) 
Goniadera pilosa, F, Bates in litt. 
Black, shining, the upper surface thickly, the under surface sparingly, clothed with long erect dark greyish- 
brown hairs. Head coarsely, irregularly, and somewhat closely punctured, transversely excavate in front; 
prothorax rather broader than long, the sides angularly extended before the middle, thence obliquely nar- 
rowing and sinuous to the base, the anterior angles broadly extending forwards and very prominent, the 
posterior angles very obtuse and obliquely truncate, the surface coarsely, irregularly and rather closely 
punctured ; elytra with traces of shallow longitudinal grooves, the surface irregularly, moderately coarsely, 
and not very closely punctured; beneath smoother and more shining, the metasternum and ventral surface 
with fine widely scattered punctures, the sides and anterior margins of the ventral segments with numerous 
coarse impressions ; legs and the basal half of the antenne also clothed with long erect hairs, 
Length 16-173 millim.
