than the -preceding. The upper claw is rather curved, in 

 the middle provided with a note//, and near the point with 

 a tooth. The tower el aw on the first pair of extremities is 

 running out into three points, on the other pairs into tzvo. 

 The mucronal segment of the furcula is short , targe, and 

 furnished with one hook. Length 7.5 mm. 



The upper claw, rather curved and nearly cuneate, is 

 in the middle of the inner margin provided with a notch, 

 and towards the point of the claw with an apparent tooth. 

 The lower claw seems to be somewhat different on the 

 several pairs of extremities. On the first it is at the point 

 cut off obliquely on both sides of the middle line and runs 

 out into three points, on the two posterior pairs the mar- 

 gin only directed towards the upper claw is cut off, and 

 the claw, therefore, runs out into only two points. The 

 tibial tenent hair is swollen. The furcula is rather short, 

 and has the mucro large and not attached to the dentes 

 with any neck, as is the case with all the other forms 

 provided with only one hook. The scales are all elliptical; 

 under the immersion-lens they seem to be provided with 

 short ribs, close lying, and as to the place exactly cor- 

 responding to the depressions which are characteristic of 

 the other species of the genus Lepidoeyrtus Bourl. The 

 scales, strange enough, do not appear before the animal 

 has been treated with caustic alkali. 



Alcoholic specimens are wax-colored, with rusty brown 

 traverses on the posterior margins of the trunkal segments. 

 The insect, when alive, is probably rusty brown all over. 

 The antenine are pale violet, the extremities yellow and 

 the furcula colorless.
