8. Scutigerella chilensis^ n. sp. PI. 3, figs. 4 a — 4 g. 



Material. — Several specimens from two localities^ but all 

 with at least ninny of the long setre broken off. 



Head. — It is short and very broad, with a very pronounced 

 lateral angle ; the longest lateral seta, situated somewhat in 

 fi'ont of the angle, is very long, much longer than the breadth 

 of the basal antennal joint. The visible part of the central 

 rod is rather long, and somewhat before the hind margin of 

 the head is connected with the vertex of a large triangle, 

 the sides of which are rather feebly developed oblique rods; 

 the frontal branches could not be observed. 



Antennae. — The number of joints varies from thirty to 

 forty. A rather small number of proximal joints with one or 

 two sette on the inner side directed much forward and some- 

 what longer than those on the outer side. The secondary 

 whorl begins below on about the tenth joint, on the upper 

 side on the fifteenth joint, and from this joint begins besides 

 a third whorl on the lower side. The seta3 in the central 

 whorl are rather long on the npper and a little shorter on the 

 lower side. The terminal joint is elongate, with a rather 

 large, long-stalked, striped organ placed on a broad protu- 

 berance, besides which there are two small organs of the same 

 kind, and some styliform, somewhat sinuate sensory seta). 



Scuta. — The second scntum (fig. 4 a) Avith the posterior 

 margin flatly convex; the antero-lateral seta3 are exceedingly 

 long, more than twice as long as the proximal antennal 

 joints; another seta inserted a little more behind is as long 

 as or even a little longer than the antero-lateral one, and 

 directed outwards and forwards ; a pair of setas on the hind 

 margin is two thirds as long as the lateral pair mentioned, 

 and some other setee are moderately long. The first scutum 

 is adorned with two pairs of setaB nearly as long as the 

 second one; the third scutum only Avith one pair of long
