1888.] INSECTS OF CHRISTMAS ISLAND. 547 



and produced in front; lower mouth-paits sometimes testaceous; 

 antennae 17-jointed, sometimes inclining to pitchy beneath, but with 

 none of the joints white or yellow ; pronotum smooth in front 

 and very finely reticulate behind, nearly quadrate, the hinder edge 

 rounded ; a central groove on the front half, on each side of which is 

 a slight elevation ; tegmina nearly smooth, broader than the thorax, 

 and I i times as long as broad ; projecting portion of the wings rather 

 narrovv, sparingly punctate, about i- as long as the tegmina, and 

 very slightly tipped with pale testaceous ; femora slightly thickened ; 

 tarsi, and sometimes the extreme tips of the tibise, ferruginous ; 

 abdomen thickly and finely punctured, the hinder margins of the 

 segments appearing as if milled. Under surface more inclining to 

 pitchy. Forceps nearly as long as the abdomen, moderately broad, 

 more or less punctured, and incurved at the extremity ; in the male 

 with a tooth at the base, and another, preceded by two or three 

 small denticulations, at two thirds of the length. 



Several specimens obtained (October 3, 1887). This appears to 

 be the common Earwig of the island ; it has considerable external 

 resemblance to Chelisoches morio, Fabr., from which the structure 

 of its legs and its unicolorous antennae will at once distinguish it.
