48 RHINOTMETUS. 



basales leviter depresso, et ad medium longitudinaliter striato, 

 rufo ; elytris subattenuatis, parallelis, striato -punctatis, ante 

 medium oblique depressis, nigro-cyaneis ; antennis robustis, Jili- 

 formibus,fuscis ; pedibus fuscis, femoribus posticis rufo suffusis. 

 Long. corp. 2 lin., lat. 1 lin. 



Oblong-ovate, narrower than the preceding species, subparallel, 

 finely punctate, black, shining. Head produced in front ; from the 

 angles of the labrum an oblique carination extends to the base of the 

 antennae, between which is a third, longitudinal and more obsolete : 

 immediately above the base of the antennae two minute tubercular 

 elevations are apparent when viewed laterally ; between these is a 

 longitudinal fovea terminating in another, transverse, which meets 

 the upper and inner margins of the eyes, thus forming together the 

 character of the letter T : the surface is thickly punctate and rufous ; 

 the eyes are tolerably large, and situated at some distance from the 

 base of the head. Thorax subelongate, constricted and rounded in 

 front; the anterior angles much depressed and obsolete, the sides 

 broadly marginate (more broadly than in the allied species) : near 

 the basal angles is an obsolete depression; while, medially, from 

 the anterior margin to the base is a distinct longitudinal stria : the 

 surface impunctate, rufous. Scutellum triangular, impunctate, fus- 

 cous. Elytra broader than the thorax (more attenuated than in 

 the adjoining species), parallel, with punctures arranged through- 

 out in the form of striae ; these punctures are minute, on a smooth 

 and glabrous surface, resembling more closely than the others 

 those of R. cyanipennis ; an antemedial transverse depression ex- 

 tends obliquely upwards towards the humeral angles, giving an 

 appearance of prominence to the surface near the scutellum; of 

 a deep dark-blue colour. Abdomen ferrugineous. Antennce robust, 

 filiform, fuscous. Legs fuscous, the posterior femora being suffused 

 with rufous. 



Distinguished from all others by its more attenuated form ; it differs 

 also from all, except E. cyanipennis, in the minute punctures of the 

 elytra, while from this latter insect it may be separated (inter alia) 

 also by its thoracic longitudinal fovea. 



From the Island of St. Paul's (on the coast of Brazil).
