 yellow. Spines yellow, tipped with black ; hind tarsi yellowish or 

 reddish.

 the head and thorax ; antennae black (including the two basal joints), 

 and pitchy towards the extremity ; face reddish. The frontal 

 concavity is black on the sides, but is filled up with yellow, which 

 forms the front of a broad yellow stripe which runs to the extremity 

 of the prothorax, of which the borders, and especially the lower 

 hinder angles, are more or less yellow ; the borders of this streak 

 above, the facial carinse, and a stripe under each eye are darker 

 than the surrounding parts. Four front legs dirty green, varied 

 with yellow ; the arolia reddish ; middle femora with a double row 

 of yellow spots on the outside. Hind femora brown above and 

 reddish beneath, with two blackish transverse bands above ; the 

 space between the lateral carinse with oblique or oval whitish or pale 

 yellow marks, and a continuous yellow stripe on the under surface. 

 Hind tibiae black above, with a yellow spot at the base, and brownish 

 yellow beneath ; spines yellow, tipped with black. Hind tarsi 

 reddish, with a black carina above ; tegmina brown, the interspaces 

 more hyaline towards the tips. Wings as in the male.

I should not have ventured to place these insects together but for 

 a memorandum which accompanied them, stating that they were 

 found in coitii by Lieut. Richardson near the shore of Christmas 

 Island on October 1, 1887. Another sjiecimen of the male was met 

 with on October 2 at Flying-Fish Cove.

 a pale line and suifused below) runs behind each eye to the extremity 

 of the pronotum ; it is intersected at the third groove of the pro- 

 notum by the pale line which runs below instead of above the hinder 

 part of the black stripe, which is conical and more sharply defined 

 than the rest ; hind femora on the inside black for half their length, 

 followed by a long black spot ; the inside sutures of the knees are 

 also black ; hind tibiae beneath black at the base and for the last 

 three quarters of their length ; spines whitish, tipped with black.

 hyaline, with pale nervures ; several of the longitudinal nervures

Female similar to the male, but much redder, and hardly speckled ; 

 edges of the frontal concavity blackish, and from this run two 

 slightly diverging blackish lines between the eyes and as far as the 

 occiput. Markings of the head and pronotum nearly as in the 

 male ; sides of pronotum varied with yellowish. Huid femora red
