Niger, undique granosus, elytris basi albis, femorum posticorum basi sanguineâ. (Long. Corp. 1 unc.) SYN. Cimex Purcis, _Drury_, _App. vol._ 3. _Brown Ill._ _tab._ 70. _f._ 2. Reduvius Nychthemerus, _Illig. Burm._ _vol._ 2. 236. 1. (Hammatocerus n.) Hammacerus conspicillaris var. _Laporte Hem._ 79. HABITAT: Virginia (_Drury_). Georgia (_Burmeister_). Head, eyes, and thorax black; the latter rough. Antennæ setaceous, consisting of innumerable articulations. Scutellum triangular and black. Corium white, terminal membrane black. Wings white and transparent. Abdomen black, the edges marked with scarlet and black spots. Rostrum black and short, not reaching to the fore legs. Legs black, the hinder thighs next the body scarlet. CERBUS SANCTUS. Plate XLV. fig. 5. ORDER: Hemiptera. SUBORDER: Heteroptera. SECTION: Geocorisa. FAMILY: Coreidæ, _Leach_. GENUS. CERBUS, _Hahn._ Anisoscelis, _Latr._ Lygæus, _Fabr._ CERBUS SANCTUS. Fuscus, thorace maculâque cruciatâ elytrorum fulvis, thorace inermi, pedibus nigris femoribus posticis maximis, tibiis mediocribus. (Long. Corp. fere 1 unc.) SYN. Cimex Sanctus, _Drury_, _App. vol._ 3. HABITAT: Sierra Leone. Head dark brown. Antennæ almost as long as the insect. Thorax orange brown, having a black streak on it next the head. Scutellum triangular and black. Corium orange brown, apical membrane black. Rostrum small and slender, not reaching to the fore legs. Legs black. Hinder thighs strong and thick, having a strong spine on the under part, and another longer, near the tip of the tibiæ. Fabricius has applied the specific name of Sanctus to one of the species of thick-legged Coreidæ, from Brazil, which is placed by Burmeister in the Genus Crinocerus. Drury quoted the Fabrician description as belonging to his species, but the diversity in their locality would alone be sufficient to prove them to be distinct. RAPHIGASTER VALIDUS. Plate XLV. fig. 6. For the description of this species, and a representation of an individual with expanded wings, see Vol. II. plate XXXVIII. fig. 4. The following are the only material variations noticed in the descriptions of this specimen as compared with that referred to above, and which can only be regarded as indicating slight variety.
