« This is probably what is described and figured by Koch as a 

 separate species under the name of Notkrus poU'mosus , fase. 29 , 

 pi. 12; it is possible, however, that poU'mosus may be the 

 nymph of Nicolet's alUed s'^ecies Bamaeus papillipes , wich he con- 

 siders to be identical with Koch's pulverulentus , fase, 29, pi. 3». 



In his first consideration Michael has been mistaken , his follow- 

 ing supposition, however, is right: Koch's Nothrus follinosus is 

 the nympha of Belha pulverulenta Koch {Bamaeus paplllipes Nic) 

 carrying its larval and nymphal skins on its back. And Koch's 

 Nothrus pulverulentus is the imago. 



The nympha delineated by me, fig. 20, is a young one, having 

 carried only one nymphal skin on its back. The skin of the pro- 

 soma is granulated , that of the metasoma recticulated (fig. 22) ; 

 that of the legs granulated too and all these granulae are insertions 

 of very little smooth but curled hairs, but they soon fall off, so 

 that only some bushes of them are still remaining on some parts 

 of the legs (fig. 21) and on the fore-part of the metasoma, as 

 shows our fig. 20. 



The pseudostigmatic organs are smooth except their distal halfs 

 which are like powdered with a transparent powder, perfectly as 

 in the nympha of Belha geniculata Linné (fig, 18). 



The long bristles, straight in their proximal halfs, graciously 

 bent in their disiai halfs, and the hook-shaped thick hairs on the 

 legs are provided with numerous prickles , and their colour is 

 smoky black (fig. 21), whilst the body is translucent yellowish, 

 louse-coloured. Koch represents the prosoma as being reddish, my 

 specimen on the contrary has a brownish hue in the middle of 

 the metasoma, evidently caused by a food-mass in the stomach. 



Curious are the two very long and at their distal ends curled 

 « tail-hairs » , the single median and totally smooth spine on the 

 back part of the metasoma, directed upwards and backwards, and 

 the long transparent , somewhat feathered hairs in the axils of the 

 common hairs on the tibiae of the first pair of legs (fig. 21). Such
