APPENDIX. 283 



Pago 81. — Add, after Physimerus trivialis, 

 14 a. Physimerus rusticus. 



P. oblongo-ovatus, latus, sat robustus, brevis, flavus et flavo-pubes- 

 cens; capite brevi, Y-foveolato, ad basin punctato ; thorace trans- 

 verso, lateribus subsinuatis; elytris depresses, latis, ante medium 

 transverse depressis, flavis, juxta scutettum macula suffusa tri- 

 angulari communi, et ad medium macula eirculari minuta fuscis ; 

 antennis jiUformibus {ad apicem sidxlilatatis), rufo-flavis, art. 

 7 et 8 fusco suffusis ; pedibus flavis. 



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



Oblong-ovate, broad, sufficiently robust, short, of a flavous colour, 

 and clothed throughout with a fine flavous pubescence. Head trans- 

 verse, hardly produced in front; above the labrum is an oblique 

 (nearly transverse) carination ; above the base of the antennae is a 

 short longitudinal channel, which is terminated by another, trans- 

 versely oblique, extending between the inner margins of the eyes, the 

 two together forming the character of the letter Y ; the surface at 

 the base is finely punctate ; the eyes are sufficiently globose, circular, 

 lateral, and situated at the base of the head. Thorax transverse ; 

 the anterior angles are depressed ; the sides are marginate and sub- 

 sinuate ; near the basal line is a well-defined transverse depression, 

 which gives a slightly gibbous form to the antemedial disk. Scutettum 

 small, triangular, of a fuscous colour. Elytra broad, robust, and 

 depressed ; when viewed laterally, a shallow antemedial transverse 

 depression gives an appearance of prominence to the surface near the 

 scutellary angles ; the colour is flavous, a suffused triangidar marking, 

 common to both elytra, near the scutellum, and a minute circular 

 medial spot between the sixth and the eighth stria? being fuscous. 

 Antennae filiform, long, with a tendency to dilatation towards the 

 apex; in colour rufo-flavous, the seventh and eighth joints being 

 suffused with fuscous. Legs flavous, the posterior tibiae being suffused 

 with rufous. 



P. rusticus is a very distinct species ; it is broad, and antemedially 

 transversely depressed ; its fuscous markings on the elytra also 

 readily distinguish it. 



A single specimen was taken by Mr. Fry, in the neighbourhood of 

 Rio Janeiro.
