HYDNOCERA. 169 
3. Hydnocera subulata. (Tab. IX. fig. 4.) 
Elongata, nigra, nitida, postice attenuata; dense fortius punctata; ore, antennis pedibusque flavis, illis clava 
fusca. Long. 54-7 millim. - 
Mas. Oculis magis distantibus. 
Femina. Oculis antice approximatis. 
Hab. Guatemata, Sabo, Senahu, Sinanja valley; Panama, Volcan de Chiriqui, 
Bugaba (Champion). 
Head wide; eyes large, especially in the female, nearly smooth; antenne yellow, 
excepting their terminal joint. Thorax with scattered deep punctures and an impressed 
central line; the sides swollen below the anterior constriction. Elytra deeply and 
rather closely punctate; their apex truncate, sutural angle mucronate, entirely black. 
Legs quite yellow. 
4. Hydnocera testacea. 
Elongata, testacea, nitida; elytris sparsim haud profunde punctulatis; capite linea occipitali, prothorace 
lateribus lineaque discoidali, elytrisque puncto apicali fuscis. Long. 43-6 millim. ¢ 9. 
Mas. Oculis distantibus. 
Femina, Capite angustiore, oculis haud prominentibus. . 
Hab. Mexico, Playa Vicente (Hége); Guarmmata, Cerro Zunil, Quiche Mountains 
(Champion); Panama, Volcan de Chiriqui, alt. 8000 ped., Bugaba (Champion). 
Head smooth, with a fuscous vitta or only two or three dots in the middle ; antenne 
with their last joint touched with a darker cloud. Thorax with a dark line on each 
side, and one or more upon the disk, sometimes obsolete, occasionally black, with the 
front and hind margins pale. The pleure and (in the Bugaba specimen) sometimes 
the breast dark pitchy black. Apex of the elytra rounded, with a dark spot. In the 
Chiriqui examples the suture is often black. The Mexican specimen has none of the 
dark markings, and, I think, may pertain to a different species. 
5. Hydnocera lateralis. 
Nigra, nitida; ore, antennis (apice excepto), palpis, elytrorum margine laterali pedibusque testaceis; capite 
subtilissime coriaceo ; prothorace oblongo parce punctulato ; elytris crebre fortiter punctatis. Long. 5-54 
millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
The head in this species is wide, and the eyes prominent. The thorax is longer than 
wide at any part; it is swollen at the sides below the anterior constriction, but not 
strongly, and is, with the head and body, usually entirely black, but in some specimens 
is yellow in front and on the disk. The elytra are scarcely as wide as the head at their 
base; the marginal pale vitta commences from the humeral callus, which it covers, and 
is continued of nearly the same width to near the apex, where it ceases; the apex itself 
has a few projecting points. The elytra are attenuated and gaping at the apex; their 
sides are not very much narrowed. Eleven specimens.
