RIIINOTMETUS. 



pale fulvous pubescence. Antennae robust, filiform, black. Legs 

 black, with slight griseous pubescence ; the claws bifid, or with an 

 inner tooth produced nearly as far as (and occasionally of the same 

 size as) the outer tooth. 



This brilliant species is in habits very active, using its wings in 

 the hot sunshine with as much readiness almost as a Lebia. The 

 species was tolerably abundant in the Organ Mountains in February 

 1857; it is represented in most cabinets. 



7. Khinotmetus assimilis. 



R. oblongo-ovatus, latus, robustus, antice attenuatus, punctato- 

 striatus, purpureo-cyaneus, nitidus ; capite elongato, longitudi- 

 naliter carinato, ad basin rugoso, nigro ; ihorace quadrato, sub- 

 elongato, antice constricto, ad basin punctato, nigro ; elytris latis, 

 ovatis, robustis, punctato-striatis, purpureo-cyaneis ; antennis 

 robustis, jiliformibus, nigro-fuscis ; pedibus fascis. 



Long. corp. 3 lin., lat. 1^ lin. 



Oblong-ovate, broad, robust, attenuated in front, punctate-striate, of 

 a deep purple colour, glabrous. Head transverse, produced in front : 

 from the angles of the labrum two obliquely transverse carinations 

 extend in the direction of the base of the antennae ; between these is 

 a medial longitudinal carination (hardly so abrupt as in R. eyaneus), 

 produced upwards between the basal joints of the antennas, thence 

 separating into two slightly diverging lines, is at last transversely 

 deflected towards the upper and inner margins of the eyes; this 

 marking is considerably less prominent than in It. eyaneus, and the 

 surface above it, at the base of the head (which is rugose), is con- 

 siderably broader : impubescent, black. Thorax quadrate (almost 

 elongate) ; the anterior angles are much constricted and depressed ; 

 the sides parallel and slightly marginate ; at the base (when viewed 

 laterally) is a transverse depression (more distinct than in R. assi- 

 milis and in R. depressus), terminating at the humeral angles in a 

 somewhat deeper fovea; the surface is subconvex and impunctate, 

 except at the base and sides, where it is distinctly punctate (thus 

 differing from R. eyaneus and R. depressus, which are impunctate 

 throughout); impubescent, black. Scutellum triangular, black. Elytra 

 broader than the thorax, ovate, robust, antemedially very slightly 

 depressed, deeply punctate-striate, the colour being a rich deep pur- 

 ple. Abdomen black, with griseous pubescence ; the segments are 

 broad, extending at tolerably equal distances along the abdomen 

 — not so much accumulated together as in R. eyaneus. Antennae 

 robust, filiform, of a fuscous-black colour. Legs robust, clothed more
