COLEOPTERA 



joints 2-6 obconical and decreasing in length, 7-11 gradually dilated 

 and laxly articulated. 



Not at all like any other New Zealand species ; its almost parallel 

 outline is characteristic. In all our species the tarsal claws are 

 thickened at the base, but not quite dentate. 



Length, i line ; breadth, quite ^ line. 



My three specimens were mixed with other species taken some 

 years ago at Tairua (near Mercury Bay). 



Group-MELANDRYID^E. 



Allopterus. 



Nov. gen. 



This new name is made for two species which do not exactly 

 accord with Eedtenbacher's Ctenoplectron ; the type is A. reticulatus, 

 which differs from Ctenoplectron fasciatum in the elytral suture and 

 margins being simple instead of coarsely ciliated ; the joints of the 

 maxillary palpi are less acute, and the tibial spurs more slender. It 

 would have been preferable to eliminate all allusion to the elytral 

 margins in the original diagnosis, but, as the author is dead, and his 

 generic name has special reference to that peculiarity of the elytra, 

 no other course seems feasible. 



No. 707 must be added to this genus, so that it may be known 

 as Allopterus ornatus, in place of Ctenoplectron ornatum. 



1410. A. reticulatus, n.s. Variegate, dull brownish-black; 

 the apex, and sometimes most of the thorax, as well as the apices of 

 the elytra, more or less rufescent ; each elytron with two large ill- 

 defined testaceous spots, one near the base, the other behind ; legs 

 and two first joints of antennae infuscate ; body lanceolate. 



Head rather narrow, with linear impressions often intersecting one 

 another. Prothorax conical, convex, widely rounded laterally, base 

 a little sinuous, obliquely depressed near each hind angle and before 

 the scutellum ; so clothed and sculptured as to appear finely reticu- 

 late, with numerous small punctures on the intervals between the 

 linear marks ; the hairs near the base yellowish, the others cinereous. 

 Elytra elongate, attenuated posteriorly, without distinct costas, 

 their clothing and sculpture similar to those of the thorax. Antenna 

 slightly longer than head and thorax, filiform ; second joint short. 

 Legs normal, tibial spurs slender, pectinate. Maxillary palpi stout, 

 intermediate joints not acuminate. 



Length, 3f~4^ lines ; breadth, j-J. 



I found three specimens at Northeote, Waiternata Harbour. 



Group CEDEMERID.E. 



Thelyphassa (p. 4 22 )- 



1411. T. COnspicua, n.s. Elongate, depressed, pale-testa- 

 ceous, pubescent ; head and thorax nearly nude and glossy ; elytra 

 opaque.
