HYPANTHERUS. 101 



Obloug-ovate, subrobust, parallel, subpubescent, flavous. Head 

 short, slightly produced ; between the eyes and above the base of the 

 antennas is an obsolete fovea in the form of the letter T ; the surface 

 is finely pubescent and thickly punctate. Thorax transverse (almost 

 quadrate) ; the anterior angles depressed and somewhat rounded ; 

 the sides marginate ; near the base are two broad postmedial de- 

 pressions, while from the head to the scutellum extends an obsolete 

 (almost imperceptible) longitudinal impression. Scutellum small, 

 triangular. Elytra broad, parallel, punctate-striate (the punctures 

 being broad and the striae shallow) ; clothed throughout with a fine 

 flavous pubescence, which can only be traced by a high magnifying 

 power, except at the apex, where it is more distinctly apparent. 

 Antenna} filiform, tolerably robust. Legs : the posterior short ; the 

 apex of the tibiae (which does not extend beyond the elytra) being 

 produced beyond the insertion of the tarsi; the globular inflation 

 above the posterior claw bright red. 



This species differs considerably in detail from H. rufo-testaceus, 

 which in general facies it resembles ; it is narrower in form, the an- 

 terior angles of the thorax are less acute, the striation on the elytra 

 is more distinct, the pubescence on the surface is closer, and on the 

 elytra there is hardly any trace of a transverse antemedial depression.

6. Hypantherus rufo-testaceus. 



H. oblongo-ovatus, robustus, subpubescens, rufo-testaceus; capite 

 inter ocidos tricarinato ; thorace quadrato, ad apicem coarctato, 

 ad basin transverse depresso, punctata ; elytris robustis, striato- 

 punctatis, ad basin Jlavo-pubescentibus ; pedibus subpubescentibus, 

 rufo-jiavis, femoribus (et tibiis ad basin) posticis fusco suffusis. 



Long. corp. 2-A- lin., lat. 1^ lin. 



Oblong-ovate, robust, sparingly pubescent, rufo-tcstaceous. Head 

 short, somewhat produced ; between the insertion of the antennae is a 

 longitudinal carination, which extends on either side obliquely in the 

 direction of the upper margin of the eyes ; within this V-shaped ridge 

 is another medial longitudinal carination, which extends to the line 

 of the base ; the surface thickly punctate. Thorax quadrate ; the 

 anterior angles slightly truncate ; sides anteriorly slightly coarctate, 

 marginate, the margination shortly and abruptly contracted imme- 

 diately behind the anterior angle ; surface at the base transversely 

 subdepressed, punctate. Scutellum small, triangular, rufo-fuscous. 

 Elytra broad, robust, with punctures arranged in the form of striae : 

 a transverse antemedial depression extends obliquely upwards to-
