3157. Synorthus mandibularis sp. nov. 



Glossy, aeneo-niger. legs and 1st antcnnal joint nifons. rcmaininii joints 

 infuscate. tarsi testaceous. 



Head with some slender greyish hairs, lather large, the forehead rounded, 

 not margined ; it is finely! distinctly, and closely punctured, but nearly 

 smooth behind. Thorax with acute and slightly prominent anterior angles, 

 its apex with slender margins near the angles only ; its pmictation liner than 

 that of the head, and apparently absent on some parts. Eh/tra with ir- 

 regular, rather shallow, and not close punetures, and appearing slightly 

 coriaceous. 



Tibiae with fine flavescent setae, the anterior nearly straight, the others 

 moderately arched e.xternally ; tarsal appendages well developed. Eyes 

 onlv slightly prominent, rotundate behind, truncate in front. Mandibles 

 tliick. curvate. and acute at the extremity as examined from above : when 

 <-arefully examined from the front they are seen to be minutely tridentate, 

 though appearing nearly truncate, at the apex. Antennae with the last 

 5 joints enlarged, 9th and lOth transverse, 3rd nearly the length of the 

 following 3 taken together ; these^ 3, though longer than broad, are not 

 <Mongate. 



Underside shining, piceous, with numerous slender pale brassy setae. 

 Metasternum distinctly but not closely punctured, the ventral segments 

 more finely and closely, the 5th even more closely. Maxillary /talpi with 

 l)roadlv ovate terminal joints, truncate at the apex. 



Differentiated by the small size and glossy In'onzed surface. S. nn'xlus 

 •can be distinguished by its pecuUar palpi.

3158. Synorthus laevigatas sp. nov. 



Glabrous, verv glossv. black, apex of thorax and exti'cmity ol elytra

 taceous, the basal joint of these last rufous. 



Head moderately convex, the forehead broadly rounded and rather 

 sharply defined, Init not margined except near the anteimae ; there are a 

 few fine indistinct punctures near the sides. Thorax with some scattered 

 fine punctures, anterior angles acutely rectangular, its sides not perfectly 

 .straight, yet hardly perceptibly curved. Ehjlra very slightly depressed 

 and pointed just at the apical margin, their punctation distant and obsolete. 



Eyes only slightly prominent. Maxillary falfi with broad terminal 

 articulations, obtuse or subtruncate at the extremity, and somewhat con- 

 cave or flattened. Tibiae with slender greyish setae, the anterior nearly 

 straight, gradually narrowed towards the extremity, without tarsal fur- 

 rows. Antennae rather short, the club 5-articulate ; joints 8-10 evidently 

 transverse, 7th sulxpiadrate, rather smaller than 8th but broader than 

 the moniliform 6th, 4th and 5th loimer than broad but not elongate, 3rd
