NEMATUS CONSOBKINUS. 131 



The larva, according to Van Vollenhoven, has the 

 head pale brown, with a transverse, ochreous-brown 

 longitudinal stripe over the crown, the jaws of the 

 colour of burnt ochre ; the eyes are placed in round 

 black spots, and the head is also covered with small 

 black hair. The skin is deeply wrinkled, shining 

 pale green. The legs are glassy green, as also are the 

 ventral legs. On the last segment are yellow projec- 

 tions with brown margins, and it is also covered with 

 short white hairs. Previous to spinning the green 

 assumes a darker tint, passing into brown. 



It feeds in September on Eobinia pseudacacia, 

 generally resting with the hind parts retracted, and 

 not resting on the leaf. The pupa state is passed in 

 the earth. 



The imago makes its appearance in June, and in 

 this country is confined (apparently) to the South of 

 England, where it has been found in the Isle of Wight 

 (Newman), near London (J. Gr. Marsh), and Norwich 

 (Bridgman). 



N. tibialis occurs also in Prussia, Holland, France, 

 and Switzerland. 



Obs. The species described by Thomson (Hym. Scand., i, 144) as 

 hortensis is not the Hartigian species, since he describes it as having 

 the head black with the exception of the mouth, the legs totally pale 

 testaceous, and the abdomen black only at the base.
