• The assignment of this species to Centrotypiis adds a new- 

 genus to the check list of the Philippine forms. Distant pre- 

 sumably had access to Buckton's type material, so that this 

 species, which was tentatively placed under Leptocentriis in the 

 earlier review, may be now assigned a definite position. 



Genus IBICEPS Buckton 



The genus Ibiceps was erected by Buckton *• to include those 

 species in which the long suprahumeral horns are sharply bent 

 backward at their tips. In other respects the genus is close 

 to Leptocentrus, having the posterior process not elevated above 

 the body, the tegmina pointed at the tips, and five apical areas 

 and two discoidals. Buckton states that the neuration is not 

 constant, but that the discoidal areas may be subdivided. 



This genus has been added to the Philippine fauna by the de- 

 scription of a new species and the reduction of an old one to 

 synonymy.

With the reduction of this species to synonjony, the genus 

 Sertorius is eliminated from the Philippine list where, indeed, 

 it is doubtful if it should have been ever placed. If was noted 

 in the former discussion ^ that the genus was of very doubtful 

 standing and was included only tentatively.

Known only from Distant's recent description which follows: 



Head and pronotum black; a frontal lateral pronotal fascia on each 

 side, two distinct discal pronotal fasciae, a central fascia to face, the 

 clypeus, and lateral sternal areas greyishly pubescent; tegmina stramin- 

 eous, apical area dark castaneous, base, costal and subcostal areas and 

 apical margin black; legs testaceous; abdomen beneath black, excluding 

 apical area, greyishly pubescent; pronotum coarsely punctate, the anterior 

 produced processes almost horizontal, very slightly recurved, their apices 

 acute, disk centrally carinate, posterior process tricarinate and passing 

 the posterior angle of the inner tegminal margin, frontal ^rea strongly 

 carinate.
