also connected by a shield which is smaller, however, than the former. 

 The V. suprastigmalis projects very much. 

 Small V. infrastifj/nialisj very large v. hasalis. No v. pedalis. 

 Mesothorax and Metathorax. V. domdis, v. dorsolateralis and 

 V. siqmtHtifjmalis all equally large. No v. infrastigmalis. Very large 

 V. hasalis. On the median side, close to the leg a small v. pedalis. 

 Abdomen 1,2. V. dorsalis large, united with that of the other 

 side. They have a dense bundle of coloured setae, length ± ^l^mnx. 

 V. subdorsalis smaller than on the other segments. V. supra- 

 stigmalis, and V. infrastigmalis are very large, v. basalis small 

 and V. pedalis also. 



Segm. 3, 4, 5, 6. V. dorsalis is wanting in most individuals. Very 

 large v. subdorsalis, large r. suprastigmalis and v. infrastig- 

 malis. Elongated but very slender v. basalis, and on the front 

 edge of the leg a small v. propedalis, on the leg some setae. 

 „ 4 and 5. V. dorsalis is present and is even rather large. 

 „ 6. V. dorsalis is small and between the v. subdorsales is 



a median brown elevation. 

 ri 7 = 6. V. pedalis, however, is placed more backwards, about 

 on the spot where the legs are joined to the segments 3 — 6. 

 „ 8 = 7, without the median elevation. V. basalis is closer 



to V. pedalis. 

 „ 9. V. dorsalis is absent and v. infrastigmalis is small ; the 

 V. subdorsales of the left and right sides are united into 

 one shield. For the rest as 8. 

 „ 10. Small but strongly projecting v. subdorsalis, v. suprastig- 

 malis, V. infrastigmalis. No v. basalis and very small v, pedalis. 

 Instar II = I but the prothoracic shield has disappeared and 

 the setae are distinctly feathered except the scattered ones on 

 the legs. The v. dorsales of the segments 6 and 7 have disappeared. 

 V. suprastigmalis is divided into two parts as in Lymantria dispar. 

 This I consider to be a coalescence of v. sujjrastigmalis and 

 V. poststigmalis and I think I could also observe this in Instar/. 

 Instar ///, IV, r= instar //. 

 During instar V a dark spot is generally present on the meso-
