XYLINADES ROELOPSI. 191 



broad ellipse , is strongly set-off and compressed ; the pu- 

 bescence of' the two last joints is pale colored and sericeous. 



The thorax is a little longer than broad at the middle; 

 its sides are strongly convex; the sharp transverse keel 

 before the basal edge is entire, curved backwards, and 

 meets the lateral keels, which are continued nearly to the 

 front margin of the thorax , under a very obtuse angle. 

 The disk , with the exception of a rather broad streak 

 before the front margin, is covered with shining warts or 

 granules which are confluent in a transverse direction and 

 form on the middle irregular transverse ridges. The rusty- 

 red pubescence forms on the disk three not very distinct 

 nor regular longitudinal lines or stripes. The scutellum 

 is very small, punctiform. 



The elytra are about twice as long as broad at the 

 shoulders; the basal margin is nearly straight, the sides 

 are parallel , the apices conjointly rounded , inconspicuously 

 sinuated by the side of the suture. They are provided 

 with punctate striae Avhich are alternately separated by 

 somewhat narrower and broader interstices ; the striae are 

 moreover provided with rows of shining granules which 

 gradually decrease in size towards the end and sides ; none 

 of these rows extends to the apex and they become still 

 shorter towards the outer margin of the elytra ; a short 

 stria provided with four granules is present at the base , 

 close to the suture. The pubescence of the elytra is of a 

 rusty-red color variegated with numerous more or less 

 squarish black dots and irregular black spots. Each ely- 

 tron has (perhaps constantly) one of these spots at the 

 basal margin at some distance from the suture , three at 

 the lateral margin (two about the middle and one at some 

 distance from the apex) , and one at the suture a little 

 before the apex , whereas a nearly circular spot common 

 to both is present just at the apex of the elytra. The 

 pygidium is semi-elliptical, covered with a rusty-red pu- 

 bescence and ])rovi(lod with large , deep punctures and a 

 sharp longitudinal keel ; the margins also are sharply raised.
