Stollia lewisi, n. s. (PL XIX., fig. 6). 



Luteous, coarsely and darkly punctate. Head shining 

 purplish-black, rugosely punctate ; antennae luteous, the 

 5th joint, excluding base, and apical half or two-thirds of 

 the 4th, black. Pronotum with the lateral angles very 

 prominent, subacute and black, their apices somewhat 

 recurved and their bases obtusely notched behind, the 

 lateral and anterior margins luteous and glabrous, the 

 whole surface coarsely covered with black punctures, 

 and with two foveate black spots near anterior margin. 

 Scutellum not reaching the apex of corium, covered with 

 coarse black punctures, the basal angles blackish and 

 containing a large glabrous, raised, luteous spot, the 

 apex with a central and two lateral small black spots. 

 Corium coarsely black-punctate ; membrane fuscous, the 

 apical margin paler. Body beneath as above, the disk 

 of the abdomen blackish, and its lateral margins nar- 

 rowly luteous and glabrous, broken with black at the 

 segmental incisures. Legs luteous, faintly spotted with 

 black, the femora more distinctly spotted, apices of the 

 tarsi black. Long. 6 mm. ; exp. pronot. angl. 5 mm. 



Hab. Awomori, Urasa and Seki, Niigata. 



The acutely produced lateral angles of the pronotum 

 give this species anything but a congeneric appearance, 

 compared with other species of the genus Stollia, and 

 rather superficially allies it with Carbula, from which 

 the broad scutellum will at once separate it. 



Alcimus borealis, n. s. 



Luteous, thickly covered with coarse dark brown or 

 blackish punctures. Head greenish black, coarsely 

 punctate, with a small central spot near base, an oblique 

 spot at inner margin of each eye, and two frontal longi- 

 tudinal fascia? on inner margin of lateral lobes, luteous. 

 Antennae black, the 1st joint testaceous, 3rd joint slightly 

 longest. Pronotum with the anterior margin, a cruciform 

 spot behind centre of same, and the anterior portion of 

 lateral margins in front of pronotal processes, luteous 

 and levigate ; the anterior space between the luteous 

 margins and the apices of the pronotal angular processes 

 greenish black, the last being notched above, and then 

 acutely produced and slightly directed backwards. Scu- 

 tellum with a somewhat large levigate luteous spot near
