 PTINUS ELEGANS, n. sp. 



Black, with the legs, the under side, the head, and the sides of the 

 prothorax covered with a cretaceous squamose indumentum which 

 on the elytra form three transverse bands hi-sinuate on each side, a 

 sub-basal, a post-median and an apical one, extending from side to 

 side, the two former unite sometimes in the median dorsal part, and 

 the inner part of the antennae is sprinkled with similar scales ; head 

 impunctate and having a fine longitudinal median sulcus ; antennae 

 robust, briefly setulose, basal joint somewhat thick, a little obliquely 

 truncate outwardly at tip, second set in the obliquely truncate part, 

 and a little smaller than the following which are gradually lengthen- 

 ing, the ninth however not being much longer than the third ; the 

 two apical ones are missing in my example ; prothorax short, trans- 

 versely impressed in the anterior part, with the anterior margin 

 raised and the transverse impression deeply and irregularly pitted ; 

 in the centre are two very high longitudinal ridges sloping in front, 

 truncate behind and reaching past the middle, the broad, smooth 

 sulcus walled by the vertical ridges is continued as a triangular 

 smooth space reaching the base, and edged on each side by two 

 slightly reddish carunculate tubercles, this basal part is constricted, 

 and the outer angle is sharp and projects outwardly ; the outer part 

 of the two ridges which are very briefly and sparingly setulose is 

 smooth, and the sides in front of the lateral tubercles have a few 

 granules ; scutellum squamose ; elytra elongate, nearly parallel, 

 rounded behind and with the humeral angles very distinctly raised, 

 they have deep striae filled with almost foveolate punctures divided 

 by tectiform very briefly setulose intervals. 



Length 3^ mm. ; width 2 mm.
