10.37.40. Hind wings and first legs free. 



10.38.20. Second legs and abdominal segments 1-3 out. 



10.39.30. Third legs out, wings bright yellow, front edges and princi- 

 pal veins black, eyes almost black, body pale green chiefly. Resting 

 period until 



10.49, when imaginal legs grasped larval skin; very slender tracheal 

 linings still connect exuvia and thoracic spiracles ; width of head of 

 adult much wider than head of exuvia. 



10.59. Abdominal segments 4 and 5 free. 



n.oo. Sixth abd. seg. free. 



n.oo.io. Seventh; 11.00.15. Eighth; 11.00.40. All abdominal segments 

 free. Wings still of exuvial length. Abdomen pale green, four lon- 

 gitudinal blue-brown lines on dorsum and spot on middle of lateral 

 carina of each abdominal segment, appendages pale yellowish green. 

 Following bluish-brown, labrum, clypeus, vertex, marks on middle pro- 

 thoracic lobe, paramedian line and broad antehumeral stripe on mese- 

 pisternum, posthumeral stripe, double line above metastigma. 



11.03, Wings lengthening, hind to end of abdominal segment 5. 



1 1. 1 1. Left hind wing as far as hind end of abdominal segment 8, 

 the other three wings to hind end of abd. seg. 7. 



11.13. Left hind wing to hind end of abd. seg. 10, the other three 

 wings to segment 8. All wings pale pea green, veins blackish. 



11.16. All wings longer than body plus appendages and subequal. 



By i P. M. the green color had left the wings how long before we 

 do not know. 



This (male) eventually colored as Thawnatoneura inopinata 

 and, with other specimens, was left to dry in a paper bag, from 

 which it was set free by some meddler on April 28 and so lost. 

 Its exuvia, however, was carefully preserved and labeled at 

 once. On the same morning and at the same place another 

 larva was found transforming and yielded a male of Th. 

 pellncida* so that our previous surmises as to the identity of 

 these larvae were established as definite facts. 



On April 30 we went again toward the higher waterfall but, 

 when we reached the mass of boulders below it, found that a

 reference was made (Ent. News, xxv. p. 345) to similar phenomena 

 in other animal groups. Since that article was published, Dr. T. S. 

 Painter, of Yale University, has called my attention to the dimorphism 

 of the males of Maevia rittaia. a jumping spider. See his paper in
