220 PACHYTERIA AP1CALIS. 



hand the extreme tip of the last ochraceous joint slightly 

 infuscate. The scape is rather deeply punctured above, 

 almost smooth below ; the 3 rd joint is not quite as long 

 as the two next following joints together, this joint as 

 well as the 4 th is provided with a sparse fringe of fulvous 

 hairs along the underside. 



Prothorax very broad and relatively short, strongly 

 transversely sulcated and narrowed anteriorly in a neck- 

 like manner and abruptly depressed and constricted pos- 

 teriorly. The posterior margin slightly turned upwards; 

 the sides distinctly but not sharply toothed and obliquely 

 narrowing in nearly straight lines from the spines to the 

 constricted front part. Both , the constricted anterior and 

 posterior portion , metallic purplish black , thickly covered 

 with short stiff black hairs , the rest ochraceous and clo- 

 thed in the middle with a short somewhat silvery shining 

 pile. The disc shows a broad but shallow impression in the 

 centre and on each side there is an other broad shallow 

 groove, originating near the lateral spine and obliquely 

 turning upwards. Between these lateral grooves the disc 

 is strongly rugosely punctured , whilst the parts outside 

 of the grooves are very thickly and finely punctate, and, 

 being moreover destitute of the silvery pile , they have 

 consequently a much more opaque appearance. The black 

 parts are also finely but not so closely punctured. 



Scutellum purplish black, elo ngate- triangular , sharply 

 pointed and delicately punctured. 



Elytra ochraceous with the greater apical third bluish 

 black, brighter towards the apex; entirely clothed with a' 

 dense short brilliant silvery pubescence. From the base 

 towards the top the elytra are gradually narrowed , their 

 apices conjointly rounded; strongly and thickly punctured 

 all over , the sculpture but very slightly decreasing towards 

 the apex, moreover each wing-case presents two faintly 

 elevated longitudinal lines. 



Underneath bluish black, with the sides and the middle 

 of the prosternum ochraceous and a small ill-defined ful-
