Broun. — New Genera and Species of Coleoptera. 417 



10th transverse, shorter and broader than 9th; terminal largest, sub- 

 rotund ate. 



Body winged. Pygidium covered. Tarsi seemingly only 4-jointed, 

 but I think they are pentainerous, with the true basal articulation small 

 and indistinctly marked off; the basal three joints of the front pairs 

 are slightly dilated. 



The large scutellum and oblique posterior portion of the elytra dis- 

 tinguish it from 2757, the typical species. 



Length, 1| mm. ; breadth, 1 mm. 



Greymouth. A single individual, from Mr. ,T. H. Lewis, October. 

 1909. 



Group COLYDIIDAE. 



3220. Syncalus explanatus sp. nov. Syncalus Sharp, Man. N.Z. Coleopt., 



p. 200. 



Convex, oblong-oval, subopaque; fusco-piceous, the front and sides 

 of thorax, as well as the legs, obscurely rufescent; tarsi and antennae 

 of a paler red; the setae yellowish, rather fine, erect along the sides, on 

 the after part of the body, and on the tibiae; on the elytra, near the 

 suture, they are depressed and fine, but beyond are irregularly concen- 

 trated, without, however, forming distinct tufts. 



Head with subgranular sculpture, resembling short rugae behind. 

 Thorax nearly twice as broad as long, disc transversely convex, the sides 

 explanate or flattened, slightly rounded and more narrowed in front 

 than behind; the anterior angles extend as far as the front of the eyes, 

 the posterior are nearly rectangular ; disc a little uneven, with irregular 

 sculpture consisting of an admixture of small flattened granules and 

 short rugae. Elytra of the same width as thorax at the base, twice 

 its length; their sculpture somewhat ill-defined; when examined from 

 behind it seems to consist of series of moderately coarse punctures, which, 

 when scrutinized sideways, appear as if they were transformed into 

 granules, a peculiarity which is also apparent in some species of Coxelus. 



Antennae sparsely pubescent, the exposed part of the 1st joint not 

 longer than the 2nd, 3rd twice as long as broad, 4th slightly longer 

 than 5th, 8th small and transverse. Club oblong, abruptly enlarged, 

 unsymmetrical, being attached to the 8th joint outside the middle, its 

 basal joint almost as broad as the intermediate, the terminal large and 

 rotund ate. 



It may be distinguished from the other recorded species by the 

 flattened sides of the thorax and peculiar sculpture. The setae on the 

 tibiae are rather fine. 



Length, 6 mm. ; breadth, 3^ mm. 



Akatarawa, near Wellington. My specimen was found by Mr. A. 

 O'Connor. 



3221. Tarphiomimus tuberculatus sp. nov. Tarphiomimus Wollaston. 



Man. N.Z. Coleopt., p. 182. 



Elongate, very uneven, opaque; fuscous; antennae and tarsi piceo- 

 rufous; sparingly clothed with inconspicuous, elongate, yellowish-grey 

 squamae. 



Head granulate, antennary orbits only moderately developed. Thorax 

 in its widest part, near the front, about a half broader than long, very 

 much narrowed towards the base; its sides bilobed, the anterior lobe 

 14— Trans.
