SYNCHITIDAE. 685 



interstices distinctly elevated at the base and behind, and with a pair of 

 smaller elevations near the extremity, fifth interstices similarly raised 

 behind. Tibiae finely setose ; basal tarsal joint but little longer than the next. 



Antennae short, thinly and finely pubescent, second joint stout, as long 

 as the exposed portion of the basal, fifth slightly longer than third or 

 fourth, the others moniliform ; club abruptly enlarged, basal joint a little 

 broader but not longer than the other. 



Underside, except the last four abdominal segments, distinctly but not 

 coarsely granulate. Mentum large, a little longer than broad. Process of 

 presternum broadly bisulcate. Metasternal process broadly triangular, its 

 oblique frontal margins somewhat raised and thickened. Basal ventral 

 segment subacuminate in front of the coxae. 



Nearly allied to G. nodosus (1936), but the body concolorous, the elytra 

 more distinctly and regularly granulate, &c. 



Length, 3 mm. ; breadth, 1| mm. 



Mount Dick, near Kingston. Captured by the late Mr. T. Hall, at an 

 elevation of 3,500 ft., on the 17th March, 1914. 



4282. Gathocles interruptus sp. nov. 



Oblong, moderately convex, opaque ; rufo-fuscous, antennae and tarsi 

 rufescent ; thinly clothed with suberect, slender yellowish setae. 



Thorax rather broader than long, deeply emarginate in front, its angles 

 prolonged to just beyond the distinctly facetted eyes, the sides finely 

 crenate, rounded and widest at the middle, somewhat sinuate towards the 

 slightly prominent hind angles, its base deeply sinuate near the sides ; disc 

 unevenly convex along the middle, with granular sculpture, its sides broadly 

 and deeply concave, the lateral margins, however, are elevated, though on a 

 lower plane than the disc. Elytra oblong, about a third longer than broad, 

 nearly vertical and evidently narrowed behind, with obtuse slightly promi- 

 nent shoulders, lateral margins finely crenulate but not expanded ; disc 

 closely and moderately coarsely seriate-punctate ; each elytron with a 

 feebly curved basal ridge just outside the second series of punctures, a 

 small nodosity on top of the posterior declivity, a still smaller a little in 

 advance, and another ridge extending from near the base to the top of the 

 hind declivity, which bears a pair of smaller nodules half-way down. 



Underside j^iceous, its margins reddish, with some fine flavescent hairs 

 and granular sculpture. Sides of prosternum deeply concave nearly to the 

 base, semicircularly emarginate in front. Intermediate coxae less distant 

 than the anterior, the frontal space broadly grooved. Metasternal process 

 subtriangular, with somewhat elevated margins. The interval between the 

 posterior coxae quadrangular, with slightly raised margins. 



Length, 3 mm. : breadth, 1| mm. 



Wellington. Found by Mr. A. C. O'Connor ; 24th April, 1916. 



Syncalus Sharp. Man. N.Z. Coleopt., p. 200. 



4283. Syncalus solidus sp. nov. 



Coiivex, compact, suboblong-oval, nitid ; fusco-piceous, the labrum, 

 legs, and basal joint of antennae fusco-rufous, remaining joints of these 

 last, the palpi, and tarsi of a paler red ; very irregularly clothed with 

 depressed, usually fulvescent, and erect similarly bright or fuscous setae, 

 in well-preserved examples suberect fulvescent setae form several crests 

 on the elytra ; on the tibiae the setae are inconspicuous and depressed.
