Spherillo spinosus. 



Corpus spinis subacutis omnino echinatum, Knarginibus parce productis ; 

 segmentis ad latera truncatis. Caput trapeziale, anticb arcuatum et 

 paulo latiu8. Segmentum thoracis anticum majus. Segmenta abdo- 

 minis lateraliter obtusa, ultimum subquadratum, ad basin non latius, 

 et apicem truncatum.

New Zealand, near Bay of Islands ; from under the bark of pine 

 trees. Collected by Dr. Pickering, March, 1840. 



Length, three lines. Colour, chestnut brown, with brownish yellow 

 along margin, and irregularly spotted along the back. The spines 

 cover closely the head, thorax, and abdomen, but not the margin of the 

 body. These spines are minutely pubescent. The margin is a little 

 flattened out or recurved, so as not to be in the same curvature with 

 the back. The joints laterally are not in contact; they are narrow, 

 rectangular, and obtuse. Surface of segments below and lateral por- 

 tions pubescent like the spines. Eyes situated near centre of lateral 

 margin of head. Posterior angles of first thoracic segment obtuse. 

 The antennae in a dead specimen were folded under the head, as in 

 figure 6 c. The flagellum is about as long as the fifth joint.
