140 PANCHRESTUS. 



anterior angles depressed ; the sides marginate ; surface thickly 

 punctate, subpubescent. Scutellum triangular. Elytra broad, robust, 

 coarsely punctate-striate, more obsoletely towards the apex (the 

 stria? being broader and the punctures deeper than in P. pulcher), 

 subpubescent (but more distinctly pubescent than in pulcher) ; a slight 

 antemedial depression extends transversely behind the shoulders. 

 Antennas tolerably robust, short, dilated towards the extremity ; the 

 joints first to fifth pale testaceous, sixth to eleventh dark fuscous. 

 Legs testaceous throughout. 



This species closely resembles P. pulcher, appearing at first sight to 

 be merely a pale and small variety of that species ; it is, however, 

 distinctly separated (as well as by its smaller form and paler colour) 

 by the form of its head, which is less produced and more attenuated 

 towards the labrum ; by the punctuation on the elytra, which is more 

 distinct and deep ; by the general subpubescent (instead of glabrous) 

 character of its surface ; and by the disposition of colouring on the 

 antennas, the transition being abrupt from testaceous to fuscous, and 

 not suffused as in the case of P. pulcher.

3. Panchrestus inconspicuus. (Tab. V. fig. 5.) 



P. oblongo-ovalis, fusco-rufus, subpubescens ; capite (inter ocidos) 

 foveolato ; thorace crebre punctulato ; elytris robustis, leviter punc- 

 tato-striatis ; antennis ad medium dilatatis, art. 1-4 fcrruijineis, 

 5-8 dilatatis, niyris, 9 testaceo, 10 et 11 niyris ; pedibus fusco- 

 rufis. 



Long. corp. 2 lin., lat. 1 lin. 



Oblong-ovate, tolerably robust, fusco-rufous, subpubescent. Head 

 small, short, produced, attenuated near the mouth ; eyes large, pro- 

 minent, but not extending laterally as far as the angles of the thorax ; 

 immediately above the base of the antennae is a short medial fovea, 

 produced (when viewed from the front) in the form of an obsolete 

 carination to the base of the head ; at the inner margin of the eyes 

 is also an oblique depression, which (in conjunction with the medial 

 line) gives an appearance of elevation to the intermediate surface. 

 Thorax transverse, rectangular; the anterior angles slightly de- 

 pressed ; the sides marginate ; at the base is a slight dcjiression, ex- 

 tending obliquely upwards towards the anterior angles ; the surface 

 finely and thickly punctate, subpubescent, especially towards the 

 sides. Scutellum small, triangular. Elytra robust, finely punctatc- 

 striate (more obsoletely towards the apex), subpubescent, especially
