between this Hue aud apex a narrow, evenly curved, ill-defined white baud 

 extending from side to side.

1 9. Lygrus bicinctus spec. nov. 



(J. Very pale bnii-yellow, glossy ; head and prothora.K deeper in tint, tip of 

 mandibles black ; antenna brown, last two segments cream-colour; two broad bauds 

 across the elytra brown, the first median, eonve.x in front, joined along outer margin 

 to second, which stands at apical fifth and is produced laterally to tip of elytra. 

 Occiput very densely punctured behiu<l. Scape of antenuc, lensely rugate-punctate ; 

 segment 3 more than twice the length of the scape and a very little shorter than 4 ; 

 segments to 10 gradually shortened, 11 a little longer than 10, less than half the 

 length of 3. Prothorax half as long again as broad in middle, subcylindrical, 

 slightly uneven, feebly rounded at sides, dispersedly punctured, scarcely any 

 punctures in mesial line. Elytra very densely and coarsely punctured, the punctures 

 especially large and close together in middle ; a feeble mesial carina, abbreviated 

 in front and behind. 



Length, 8 mm.

One c?. 



The eye is sinuate, having a distinct but rather short upper lobe. 



Idiocalla gen. nov. 



c? ? . Head broad, interspace between upper lobes of eyes about half the width 

 of the thorax aud twice the height of the frons ; the latter more than twice as 

 broad as high ; antennal tubercles widely separate ; a mesial sulcus between them. 

 Antenna a Tittle longer (cJ) or shorter (?) than the body, filiform, segments 3 to 7 

 almost the same length ; scape with subapical, transverse, carved carina, the half- 

 moon-shaped space (cicatrix) encircled by it with another carina. Prothorax broader 

 in middle than long, irregular above, sides obtusely nodose, not dentate. Scutellum 

 longer than broad, rounded at end and minutely incised. Elytra broader than 

 thorax, truncate-sinuate at base, the rounded shoulders projecting a little, fiat (as 

 in Callidium), sides jiarallel, apex of each rounded. Prosternal process narrow, 

 reaching beyond coxae, coxal cavity ojien ; mesosternal process triangular, obtuse. 

 Femora club-shaped. First abdominal segment of c? three times, of ? four times, 

 the length of the second ; a large cavity on third to fifth in ? , fringed with hairs. 



Type : LliocaUafi'.rragineus (180-t) Jord., described as a St-manotus. 



A cicatrix-like structure occurs also in some of the species allied to Fsebium, 

 with which Idiocalla has much in common, though the body is not long-hairy and 

 the elytra are not abbreviated. 



20. Idiocalla postica spec. nov. 

 ?. Similar to G. fevrughims (180-ij Jord., deeper ferruginous; femora with 

 red ring; elytra black at apex, the black area about 2 mm. wide ; prothorax more 

 strongly dilated laterally in middle and less obviously nodose above, and elytra 

 wider at base, than in ferruyineus.
