joint bilobed. There is a small, black, polished tubercle on either 

 side of the scutellum. 



Length (rost. excl.), 2f; breadth, If lines. 



Mr. G. V. Hudson was kind enough to give me the specimen 

 that he found under pukatea bark at Karori, Wellington. 



Group-COSSONID^E. 



Pentarthrum. 



2188. P. fulvum, n.s. Fusiform, without distinct pubescence, 

 shining, pale-red, legs and elytra of a yellowish hue (fulvescent) , 

 tarsi yellow. 



Pentarthrum longirostre is the nearest ally. This differs in being 

 smaller ; the rostrum is a little shorter and thicker, and is quite 

 parallel-sided, shining, finely but not closely punctured, and with 

 some fulvous setae at the tip ; the antenna are inserted just before 

 the middle, they are fulvous, with the club ovate, opaque, fuscous, 

 and densely pubescent ; the thorax is rather flat above, is less 

 rounded laterally, and its punctuation is rather fine ; the elytra are 

 less fusiform, with less evident striae, the punctures are somewhat 

 finer and not so close to one another. 



$ . Length, If lines ; breadth, nearly f line. 



Paparoa, near Howick. One example. 



OBS. All my measurements of Cossonidae include the rostrum. 



2189. P. fultoni, n.s. Variegate, rostrum dark- red, head rufo- 

 piceous, thorax and legs chestnut-red, elytra rather paler but suffused 

 with a darker colour, antennae red ; body shining. 



There is no species like this except P. melano sternum, which, 

 however, is only slightly shining, being, in fact, subopaque. The 

 rostrum has a broad longitudinal channel, and is distinctly punctate ; 

 the head is broader, densely and minutely sculptured, and has some 

 distant, moderately fine punctures, it is constricted behind the eyes. 

 Antennas inserted almost before the middle ; scape short, thickened 

 apically ; second joint of funiculus distinctly longer than third ; club 

 ovate, pubescent. Thorax rather more narrowed but less constricted 

 in front, so that the apical margin is not so thick, the punctures are 

 a little finer and more distant. Scutellum polished. Elytra cylin- 

 drical, their apices not explanate, striate-punctate, second and third 

 striae well marked behind, their punctures not so coarse as in 

 No. 1548, interstices rugulose, with fine serial punctures. The 

 clothing is less conspicuous, being short and slender and not so 

 yellow. 



Fern. Rostrum slightly longer and thinner than in the same sex 

 of No. 1548, a little contracted behind the middle, cylindric, shining, 

 and finely punctate ; scape more slender. 



Length, If lines ; breadth, nearly f line. 



Taieri. One pair, sent by Mr. S. W. Fulton, whose name has 

 been applied to the species.
