Metobeiubi {Ohriinie), u.g. 

 Head large, broad between the eyes, attenuated posteriorly, 

 concave between the antennal tubercles ; with the eyes prominent, 

 coarsely facetted, feebly emarginate in front, widely separated 

 above. Antennae more than half as long again as the body, with 

 the third and fourth joints short, subequal, together scarcely 

 longer than the scape ; with the fifth and following joints com- 

 pressed, each longer than the third and fourth combined. Pro- 

 thorax twice as long as broad, horizontal for a short distance at the 

 base, tlience inclined upwards and anteriorly bent forwards so as to 

 form with the head a sub-semicircular curve ; the middle of each 

 side with an obtuse tubercle or angle, in front of and behind 

 which the prothorax is slightly constricted. Elytra linear, a little 

 retracted and triincate at the apex, with the lateral margins sinuate 

 in the middle. First segment of the abdomen as long as the three 

 following united. Prosternal process subhorizontal posteriorly, and 

 jiroduced a short distance behind the cotyloid cavities ; the latter 

 completely closed in behind. Intermediate cotyloid cavities open 

 on the outside. 



Type : — Mctohrinm clcqans, Fairm., Ann. Soc. Ent. de 

 France, 1887, p. 334, pi.' 3, fig. 9. 



A figure of this species and a very full description 

 have been given by M. Fairmaire, but he has erro- 

 neously referred it to the genus Ohriaccum, of Thomson. 

 From this genus it is at once separated by the greater 

 width of the head, the length and curvature of the 

 thorax, and the difterent relative proportions of the 

 basal joints of the antenna. 



The genus Ohriaccam is, as pointed out in M. Lameere's 

 supplement, synonymous with the previously charac- 

 terised Ossibia of Pascoe. 



Hypakgyra, n. g. 



Head concave between the antennal tubercles ; front subvertical, 

 a little broader than long, feebly transversely impressed near the 

 base. Antennae a little longer than the body, with joint 3 much 

 longer than the scape, with joints 4 — 6 subequal, each shorter than 

 3rd, with joints 7 — 10 gradually decreasing in length, 11th longer 

 than 10th. Eyes finely facetted, deeply emarginate. Prothorax 

 sub-cylindrical, a little longer than broad, feebly rounded and 

 unarmed at the sides, and very slightly constricted at the base. 

 Scutellum forming a nearly equilateral triangle. Elytra slightly
