264 IMATIUM. 



This species may be recognized (as compared with /. tomentosum) 

 by its more pale flavous colouring (instead of ferrugineous), by the 

 form of, and transverse depression at the base of, the thorax, by 

 the less distinct dilatation of the antenna), by the character of the 

 punctuation on the elytra, and by the colouring of the antenna) and 

 anterior tarsi.

3. Imatium velutinum. (Front, fig. 8.) 



I. ovatum, latum, subtillter flavo-pnbescens ; ilxoraee transverso, 

 ad latera sinuato vel subrotundato, punctato ; elytris robustis, 

 brevibus, ante medium transverse depressis, punetato-striatis, 

 ad basin distincte pubescentibus ; antennis brevibus, art. 1-4 

 Jlavis, 5-9 dilatatis nigrisque, 10 et 11 Jlavo-testaceis ; pedibus 

 JJavis. 



Long. corp. 2 lin., hit. 1-i- lin. 



Ovate, broad, covered with a pale fulvo-fiavous pubescence, of a 

 flavous colour throughout. Head short, depressed, hardly produced ; 

 above the base of the antenna? and between the eyes is an obsoletely 

 transverse, and another longitudinal depression, crossing each other 

 at right angles ; the eyes are tolerably large, situated close to the 

 basal line ; the surface is thickly punctate. Thorax transverse 

 (almost quadrate), depressed ; the anterior angles are subacute; the 

 sides are marginate, and slightly constricted close to the anterior and 

 posterior angles, and medially rounded ; at the base is a slight trans- 

 verse depression ; the surface is slightly rotundate, thickly punctate, 

 and finely pubescent. Scutellum triangular, impunctate, flavous. 

 Elytra broad, robust, parallel, punctate-striate (the stria) being shallow, 

 and the punctures broad) ; a transverse antemedial depression ex- 

 tends obliquely and upwards towards the humeral angles, giving an 

 appearance of prominence to the surface adjoining the scutellum; the 

 sm-face is almost glabrous (except under a high power, when it is seen 

 to be finelj T pubescent), more distinctly pubescent at the apex. An- 

 tenna} robust, somewhat dilated towards the apex ; the joints first to 

 fourth flavous, fifth to ninth dilated, and in colour black, the tenth 

 and eleventh flavo-testaceous. Legs tolerably robust ; the terminal 

 joint of the posterior tarsi strongly bilobed ; the posterior robust aud 

 abbreviated ; the colour is flavous throughout. 



I feel some hesitation in placing this species in the same group as 

 /. tomentosum and /. rotundatum ; it is not quite so rotundate, the 

 elytra (though broad and robust) arc hardly hemispherical, and the 

 form is not so globular; inasmuch, however, as there is little, except
