458 COLEOPTERA. 



it before the middle, giadually depressed and attenuate posteriorly ; they 

 are rather finely subseriate-punctate behind the middle, indistinctly so 

 near the base. 



Antennae stout, quite immaculate, extending to beyond the posterior 

 femora ; their 3rd joint reaches the base of the thorax and is nearly twice 

 the length of the 4th, which is slightly longer than the 5th. Legs stout, 

 tibiae finely setose beh)W the middle. 



In general outline this approaches *S. flavidorsis, but the elytra before 

 the middle are rather broader than the smaller thorax, the scutellum is 

 larger, and the sculpture and coloration, as well as the antennal structure, 

 are essentially different.

Heaven's Gate, near Mount Earnslaw. Another of Mr. T. Hall's 

 uniques, obtained from decayed leaves at an elevation of 1,200 ft. on the 

 6th February, 1914. 



3949. Somatidia femoralis sp. nov. 



Body moderately elongate and convex, a little shining and uneven ; 

 castaneous, dark fuscous along the sides and on the posterior slope, but 

 with the sides of the latter light chestnut ; the middle and hind thighs 

 testaceous, the former with an infuscate median mark, the front pair 

 castaneous and stouter than the others ; the tarsi and lower part of the tibiae 

 testaceous, the latter with the usual dark marks ; pubescence distinct, de- 

 pressed, tawny grey, not forming definite spots ; there are no erect setae. 



Head broadly depressed between the antennae, dark fuscous, distantly 

 punctate in front. Thorax as long as broad, its sides gently rounded ; 

 distinctly but not closely and irregularly punctured, slightly uneven, with 

 a small, very obtuse, sometimes greyish tubercle near each side behind the 

 middle. Elytra moderately elongate-oval, double the length of thorax, 

 a third broader than it is in the middle ; moderately coarsely subseriate- 

 punctate nearly to the extremity ; each elytron with a small crest nearly 

 in line with both the middle and hind thighs, and just outside and below 

 the posterior one a slight obtuse plica extends nearly to the apex. 



Antennae only slightly longer than the body, with slender greyish setae 

 and pubescence, they are chestnut-red, with fuscous apices from the 

 4th joint onwards, the 3rd is more spotted and extends beyond the base 

 of the thorax, 4th rather shorter than the preceding but longer than the 

 following one. 



No other recorded species is exactly like this. It may be distinguished 

 from others of equal size by the quadricristate hind-body and obtuse 

 subapical costae.

Moa Basin, Canterbury. The specimen was found on the 3rd December, 

 1913, by Mr. T. Hall, amongst dead leaves. 



Obs. — In a second example from Unknown Land, beyond Moa Basin, 

 the hind part and sides of the elytra right to the base form a continuous 

 blackish mark, but the subapical costae are obsolete. This, I think, is 

 merely a varietal form of the type.

Subnitid, rather stout, slightly convex, a little uneven ; light castaneous, 

 with a fuscous mark on each elytron just behind the posterior femur, this
