 nens ; capite brevi, ad basin sparsim punctato ; thorace transverso, 

 impunctato, ad basin transverse foveolato, ferrugineo, ad latera et 

 ad medium longitudinaliter fusco ; elytris latis, punctato-striatis, 

 ad medium transverse et juxta humeros longitudinaliter fusco- 

 notatis, marginatione etiam et sutura antemediis fuscis ; antennis 

 jiliformibus, jlavis ; pedibus flavis, femoribus posticis ferrugineo 

 sujftisis.

Oblong-ovate, sufficiently robust, depressed, impubascent, glabrous, 

 of a brigbt rufo-ferrugineous colour. Head transverse, considerably 

 depressed, not produced in front ; above the labrum is an obsolete 

 triangular depression ; the surface of the base is levigate and sparingly 

 punctate; the eyes are large and globose, in form oval. Thorax 

 transverse, rectangular ; the lateral margins are parallel (slightly 

 subsinuatc towards the apex) ; the surface is smooth and impunctate ; 

 parallel to the basal line is a minute transverse thread-like fovea, 

 corresponding in form to the thoracic depression in the genus Mono- 

 platus ; in colour the thorax is rufo-ferrugineous, being broadly 

 margined at the anterior angles with fuscous, a suffused medial 

 longitudinal band is also fuscous. Scutelhm triangular, impunctate, 

 fuscous. Elytra distinctly broader than the thorax, finely punctate- 

 striate, in colour rufo-ferrugineous; a suffused medial transverse 

 fuscous marking extends from the suture to the margination, and 

 thence upwards to the humeral angles ; near the scutellum (between 

 the fourth and sixth stria?) is a short suffused longitudinal marking 

 of fuscous ; the suture also is antemectially fuscous. Antenna} fili- 

 form, in colour flavous. Legs fiavous, the posterior femora being 

 suffused with ferrugineous. 



P. Allardi is separated from its congeners by the form of its 

 thoracic basal fovea ; it is also readily distinguished by the broader 

 and depressed form of its elytra, and by the transverse medial and 

 scutellary longitudinal marking. 



Taken by Mr. Fry in the neighbourhood of Rio Janeiro. 



I name this species after my friend M. Allard of Paris, the excellent 

 monographer of the Halticida) of Europe.
