'' Head broadly ovate, narrowed towards the front, with an elevated 

 margin behind, and an impressed curved transverse line, convex backward, 

 on the top before the eyes ; space between the antennae concave. Dental 

 lamina with eight acute teeth. Antennae tomentose, with 34-36 joints. 

 Segments 15 (without the head), alternately large and small ; but the small 

 segment between the 7th and 8th, and between the 14th and 15th, absent ; 

 each segment with a raised margin. Above olive-brown, generally more 

 or less marbled with black ; legs pale-bluish ; feet yellow. Under-surface 

 of head and region of anus reddish. Some scattered hairs on the legs. 

 Length 0-6 in. 



" Hab. — Dunedin and Queenstown. 



'' It is astonishing with what rapidity this creature runs."' — (Hutton.) 



The type of this species has been lost, and I have not seen any speci- 

 mens corresponding exactly with the above description. Hutton does not 

 mention any characters at present regarded as critical which would dis- 

 tinguish it from H. maeulatus, except the number of praecoxal teeth. I 

 take Hutton's " eight acute teeth " to be equivalent to 4+4. From the 

 specimens I have examined of H. maeulatus, it appears to have 3+3 teeth 

 uniformly, and so, in the absence of definite information, I do not think it 

 advisable to combine H. maeulatus and H. impressus at present.
