antennae serrate, but the joints longer than broad, the third 

 hirgest ; the basal joints have a reddish-bi-own tint, caused by a 

 very short sericeous pubescence. The thorax has a broad recurved 

 lamellate lateral margin ; the anterior angles are acute and 

 pi'ominenfc, the apex emarginate on each side and roundly lobed in 

 the middle, from the acute anterior angles the foliated sides 

 extend outwards and upwards to an angle behind the middle, 

 whence they run straight to the posterior angles, which are 

 scarcely acute. Tlie base is biemarginate as usual, the disk is 

 black from the base to the central anterior areolets ; the 7 areolets 

 are less deeply and more rugosely marked than in the last 

 described species. The description of the elytra is the same.

33. Metriorhynchus hirtipes. 



This species differs very much from all the species of Metrio- 

 rhynchus I have seen. Black, excepting the elyti'a and the foliated 

 lateral margins of the thorax, which are red. Rostrum long, 

 nearly cylindrical, maxillary palpi swollen at the apex. Antennae 

 long, the 3rd joint much longer than the 4th ; from the 4tli to the 

 10th the inner ajjical angles are much produced. Thorax widely 

 foliated on the sides and in form an exaggerated resemblance to 

 M. foliatus, but with the apex of the anterior angles rounded ; the 

 anterior central areolets are rather confounded with the discal one, 

 which is large and deep. The scutellum is black. The elytra are 

 long and taper towards the apex ; the sculpturation like that of 

 the other species. The legs are clothed benetith with long fulvous 

 hair. The sides of the abdominal segments are whitish.

34. Xylobanus fumosus. 

 Entirely of a smoky brown. Antennae broadly serrate, com- 

 pressed, the third joint not longer than the fourth, the last joint 

 the longest. Thorax a little broader than long, distinctly 7- 

 areolate, the apex and anterior angles rounded, the sides almost
