68 NEMATUS APPENDICULATUS. 



Yollenlioven figures it with the first transverse cubital 

 nervure very distinct. 



The larva has been described by Gimmerthal and 

 Yollenhoven. It has the head somewhat depressed 

 anteriorly; its colour greyish -green, the eyes being 

 placed in rather large round black spots ; from each of 

 these spots proceeds a brown line, narrowing gradually 

 and going to the top of the head where the lines join. 

 About the mouth parts are some small brown spots, 

 and the tips of the mandibles are of the same colour. 

 The body is rather long and slender. Above the line 

 of the spiracles it is strongly wrinkled, there being 

 five folds to each segment. The second and eleventh 

 segments, the edges of the spiracles, the middle and 

 posterior legs and the top of the anal segment have a 

 green-yellow tint ; the rest of the body is green ; legs 

 greenish, with brown claws ; there is an oblique mark 

 on each of the thoracic. 



Usually it feeds lying at full length along the edge of 

 the leaf, with the posterior segments slightly curved. 

 It feeds on Ribes rubrum and R. grossularia to which, 

 when they occur in numbers, they are injurious. 

 It appears in June, spins its little shining cocoons 

 in the earth, and emerges in the perfect state in July, 

 there being two generations in the year. 



Appendiculatus, although widely distributed, does 

 not appear to be very common in this country. I 

 have taken it in Clydesdale, Braemar, and Sutherland- 

 shire. In England it is found in the Manchester dis- 

 trict, York (T. Wilson), Gloucester, around London, 

 Glanville's "Wootton, and Devonshire. 



Continental habitats are : Scandinavia, Germany, 

 Holland, France, Russia (Riga). 



Obs. It is doubtful if this is pallipes, Lep., for the mouth and tegulse 

 are said to be ferruginous, which is not the case with any of the speci- 

 mens I have seen ; but it is difficult to see what other species pallipes 

 can be.
