30. Ili/llisia qnadricollis , Fairrn. 



Loc. Seychelles : Mahr, near Morue Blauc and Cascade 

 Instate, n specimens. 



Fairmaire descril)ed this species as an Hippopsis. The 

 species of Hippopns have, however, the head and eyes 

 differently shaped, and seem to be restricted to the American 

 fauna. 



H. qundricoUis ajrrees well with the genus HyUisia, and 

 seems nearly allied to H. vittata, Fahr., which by its short 

 hind femora and the truncate apex differs from the type of 

 HifUisin (stenideoides, Pasc). The antennieare (as in typical 

 HyUisia) 12-jointed, and the first joint reaches the base of 

 the prothorax. The antennal joints 1-5 are ciliated beneatii 

 with the ciliae of joints 3-5 very lonj^ in the male ; lower 

 lobe of the eye elongate, much longer than broad, and 

 nearlv thrice as long as the gena ; front strongly punctured 

 and more >o in the male th:in in the female. 



31. Exuccntrus reticulatus, Fairm. 



Loc. Seychelles: Long I , vii. 1908, 1 example; Auonyme 

 I., i. 1909, 3 specimens; these localities are two small 

 coconut- planted islets near Mali(5. 



Known from Madagascar and the Comoro Islands, but 

 not ))reviously recorded from the Seychelles, Fairmaire 

 erected in 1901 for this and three other species from 

 Madagascar a new genus Pseudocentn/s, which, lunvever, 

 seems not to be sufficiently distinct from Exocentrus. 



Mahenes, gen. nov. (Acanthocinorum). 



Head a little broader than the prothorax at apex. Front 

 transverse, somewhat depressed in the middle. Eyes 

 coarsely facetted, cmarginate; lower lobe sulnjuadrate, 

 twice as long as the gena. Antenimry tubercles broadly 

 separate and strongly divergent. Antennce nearly twice 

 as long as the body, 11-jointed, ciliated beneath to apex, 

 but without hairs above; first joint obconic, rather 

 short, not or hardly reaching the middle of the prothorax, 

 much shorter than the third joint; third and fourth joints 

 nearly equal; the following joints much shorter, Prothorax 

 suhquadrate with a small tubercle on each side behind the 

 middle; the sides slightly arcuate; the base hardly nar- 

 rower than the apex. ScutellUm short and broad, rounded
