OF NEW ZEALAND. 397 



Intercoxal process not extending beyond the hind coxae, rounded in 

 front. 



Allied to Tanychilus; the space between the front and intermediate 

 coxae much less depressed, and the coxae themselves not so far apart ; the 

 form of the prothorax quite different. 



700. X. SUbstriata, n.s. Head short, rounded, vertex rather 

 convex, forehead depressed ; labrum with the sides rounded, the apex 

 scarcely truncate ; its surface is punctate, the punctation of the front 

 part rather closer than on the vertex ; eyes rather large. Antenna. 

 ferruginous, pilose, the third joint scarcely longer than the fourth. 

 The thorax is about as long as it is broad, somewhat convex, very finely 

 and indistinctly margined \ the sides are considerably rounded in front 

 of the middle, but behind they are almost parallel, with obtuse posterior 

 angles ; the base is slightly bisinuated. the apex sub-truncate ; its surface 

 bears many shallow punctures, and an elongate frontal depression. 

 Elytra sub-oblong, finely margined, broader than the thorax, somewhat 

 convex, with obtuse shoulders, slightly incurved sides and individually 

 rounded apices ; they are rather feebly striated, but the lines of punc- 

 tures are distinct. Tibia moderately arcuated. Palpi securiform. The 

 head and thorax are piceous, the elytra and femora fuscous, the 

 antennae, tibiae, and tarsi rufo-testaceous. 



Length, 3^ lines. 



I took two specimens at Tairua in different years, both out of the 

 decaying portion of a standing tree. 



701. X. tibialis, n.s. This species is precisely similar in form to 

 the preceding. The body is moderately shining, the thorax is piceous, 

 the head and elytra fuscous, the antennae, palpi, and legs dark rufous. 

 The head is distinctly and somewhat remotely punctured, and constricted 

 behind. The thorax is impressed with small shallow punctures, two 

 much larger yet less distinct ones near the middle, an elongate depres- 

 sion near the scutellum, and a less distinct one on each side between it 

 and the hind angle. Scutellum triangular. The elytra are striated, 

 their punctures larger than in the preceding species, and the interstices 

 slightly convex, the sculpture, however, presents a rather interrupted 

 aspect towards the apex. The anterior femur, near its base, has a 

 distinct almost protuberant process, and the tibia on the inside, near 

 the middle, is a little excised ; the other two pairs of tibiae are slightly 

 arcuated ; claws inwardly serrated. Terminal joint of palpi cultriform. 



Length, 4 lines. 



Tairua, where I found only one example of the species. 3%e- gonus- 

 -ef-both of thooc opccieg seems doubtful. 



FAMILY PYTHIDES. 



Mentum transversal. Ligula somewhat prominent. Maxilla bilobed, 

 lamelliform, and ciliated. Mandibles often toothed inwardly. Head not 

 contracted at its base, prominent, horizontal or slightly bent. Eyes 

 lateral, entire. Antenna eleven-jointed, moderate, inserted at the front
