736 COLEOPTERA 



interstices punctulated. Legs pubescent, rather elongate ; the third tarsal 

 joint bilobed, but not much expanded. AniejincB long, inserted just 

 behind the middle of the beak ; scape long, rather slender, strongly 

 flexuose ; second joint of the funicle decidedly longer than the third. 

 Sternum plane, moderately punctured, dark red ; mesosternum almost 

 smooth ; metasternum with a short median groove behind. Ahdomen 

 black, the last four segments much more finely and closely punctured 

 than the first. 



Length, \\; breadth, \ line. 



My specimen, probably the female, was found at Wellington by Mr. 

 P. Stewart. The long flexuous scape implanted behind the middle of the 

 rostrum is distinctive. 



1307. P. castum, n.s. Body sub-depressed, dark red, elytra 

 suffused with a darker hue, legs and antennae red ; somewhat glossy, 

 clothed with yellow and greyish hairs, those of the former colour long and 

 slender on the thorax, but short on the elytra. 



Rostnim moderately long, narrowed behind, punctulate, the sculpture 

 coarser on the head ; neck rather short, not quite smooth ; eyes prominent. 

 Prothorax triangularly ovate, a little constricted and depressed in front, 

 with rounded hind angles, moderately closely and distinctly punctured. 

 Scuiellum smooth. Elytra sub-truncate at base, narrowed posteriorly, 

 punctate-striate, the punctures more obvious than the grooves, interstices 

 punctulated ; they appear rugulose and rather densely clothed, the yellow 

 hairs are easily seen, but the numerous rather long and very slender grey 

 ones can only be perceived on a careful examination. Legs stout ; third 

 joint of the feet sub-bilobed, but not dilated. Antennoe inserted almost 

 before the middle of the beak, rather elongate ; scape rather slender and 

 but little incrassated at the extremity ; funicle as long as the scape, the 

 second joint not perceptibly longer than the third ; club ovate, not short. 

 Under-side nearly plane, dark red, with minute semi-erect yellow hairs, 

 moderately punctured ; metasternum canaliculate. The two basal segments 

 of the abdo)?ien distantly punctured on the middle, the sutures of the other 

 three edged with coarser punctures. 



Distinguished from the depressed Pentarthra by its clothing, &c. ; the 

 anterior half of the rostrum is parallel, the posterior narrowing is not con- 

 tinuous, merely a broad incurvature behind the middle ; the thorax is not 

 short. 



Length, quite i^; breadth, nearly \ line. 



My specimen, obtained somewhere near Whangarei Harbour, I 

 believe to be a female. 



Macroscytalus. 



Nov. gen.

 Bostrum shorter than the thorax, not abbreviated, narrowed behind the 

 middle. Eyes moderate, not convex. Head exserted, curved laterally, 

 occiput smooth. Antenncc stout, rather long, inserted at or near the 

 middle ; scape incrassated, attaining the eye ; funiculus short, 5-articu-
