128 HOMOTYPHTJS. 



tubercles are observable medially, near the anterior margin, while 

 on either side of these, adjoining the anterior angles, is an indistinct 

 depression ; near the basal angles, also, are two other obsolete de- 

 pressions : the surface (when viewed under a high power) is very 

 sparingly clothed with pubescence, and coarsely granulated. Scutel- 

 Iwm small, triangular, rounded at the apex, impunctate, and fuscous. 

 Elytra much broader than the thorax, robust, punctate -striate, the 

 stria? being very indistinct, and near the suture obsolete, while the 

 punctures are very large and deep : the surface is clothed with a close 

 and very fine pubescence of a fulvo-ferrugineous colour, mottled 

 throughout irregularly with ashy grey, and at the sides and base 

 more distinctly fulvous. Antennae incrassated at the apex ; the first 

 joint being long and dilated ; the second much shorter and narrower ; 

 the third, fourth, and fifth of equal length, longer and slightly nar- 

 rower than the second ; the sixth to the eleventh shaft and dilated, 

 broader than the first and shorter than the second : in colour the first 

 to the fifth are flavous, the first being suffused with fuscous, and the 

 fourth and fifth and also the base of the sixth testaceous ; the seventh, 

 eighth, and the apex of the ninth darkly fuscous ; the tenth and 

 eleventh testaceous. Legs robust, fuscous throughout. 



This species may be distinguished from H. squalidus not only by 

 its more close and differently coloured pubescence, but by the obso- 

 lete striae on its elytra, which in the latter species are well-defined.

Long. corp. If lin., lat. f-1 lin. 



Ovate, broad, subdepressed, subpubescent, fulvo-ferrugineous. 

 Head short, abruptly transverse, hardly produced ; above the labrum 

 is a transverse, triangular, slightly elevated plane (black) ; above the 

 base of the antenna; (which are contiguous) is an obsolete fovea, in 

 the form of the letter Y : eyes situated at the base of the head, and 

 extending laterally as far as the anterior angles of the thorax : the 

 surface is finely granulated, pubescent, and flavo- rufous. Thorax 

 small when compared with the breadth of the elytra, transverse, 

 rectangular ; the sides slightly marginate and parallel ; at the base 

 are two broad subdepressions ; the surface is granulated, finely
