Niponius foveicollis, sp. n. (PI. VIII. fig. 6.) 



Elongatus, cylindricus, niger, nitidus ; fronte in medio transverso 

 kevi; pronoto 4-foveolato ; ely tris striis suturali, apice abbreviate, 

 cseteris obsoletis ; propygidio 4-foveolato ; pygidio profunde bi- 

 foveolato. 



L. 5 mill. 



Elongate, cylindrical, black, and shining ; the head irregu- 

 larly punctured, points varying in size, on the vertex there is 

 a transverse smooth space which is marginate anteriorly and 

 narrows behind in the middle and then widens out irregularly 

 before the neck ; the thorax has large irregular punctures 

 and four foveas, two near the anterior angles, two behind the 

 middle of the disc; the elytra, the sutural stria, which is a 

 little shortened apically, is markedly continued along the 

 bases and turns backward before reaching the humeral angle, 

 and there apparently represents the first dorsal stria, the other 

 stria? are obsolete or consist of linear punctures ; the pygidia 

 are very smooth ; the propygidium has two small centre 

 fovea? and two larger ones near the edges ; the pygidium has 

 two large fovea? almost circular in outline ; the prosternum, 

 stria? strong and feebly joined posteriorly and markedly 

 terminating without joining anteriorly ; the mesosternum is 

 somewhat widely canaliculate ; the metasternum, the canalicu- 

 lation is narrower but more marked, and the surface punctua- 

 tion is extremely fine ; the anterior tibia? are bidentate.

Cylindricus, parum robustus, niger, nitidus, abdomine pedibusque 

 rufis ; elytris punctatis, unistriatis, basi marginatis ; propygidio 

 parum dense punctulatis, baud foveolato; pygidio utrinque 

 arcuatim sulcato. 



L. 5| mill. 



Cylindrical, rather robust, black, and shining, legs and 

 abdominal segments red ; the head somewhat rugosely punc- 

 tured, carina? on the cephalic armature well marked ; the 

 thorax, surface punctured more clearly than the head, with 

 two large fovea?, one on each side of the disc, and a transverse 

 impression on the edge behind the anterior angle ; the elytra 

 strongly margined along the bases, with one short stria near 

 t lie humeral angle, surface clearly but not densely punctu- 

 late (points smaller than those of the thorax) ; the pro- 

 pygidium is more finely and more closely punctulate, without
