Plate XV. 



(To be bound facing Plate XV.) 



Pupal skin and pupal hairs of L.eosopis roboris, near dorsum of 

 5th abdominal segment. 



Portion of pupal skin of Laeosopis roboris x 200. 



Taken from front margin of 5th abdominal segment near dorsum. It shows the 

 most typical fungiform hairs (like those in Chrysophanid pupae, see vols, i., pis. x., 

 xi., xiv.) yet met with in a Ruraline pupa, the next nearest being those of Bithys 

 querent* (see pi. iii., fig. 2), but these latter are merely ordinary hairs with somewhat 

 developed tips. The fig. shows how the ribs of the network fail at the bases of 

 these hairs, and how they are gathered up at the rosettes at their junctions. 

 These rosettes have a rather elaborate central point, but no radiated structure in 

 this species. The plate shows well, also, how the ribs of the netting divide down 

 into the lines of the surface tessellation (a form of skin-points? or, perhaps, skin- 

 points are rather those of the tessellation due to the dermal cells). It also shows, 

 though not very clearly, how these tessellations towards the margin of the segment 

 change their character to spicular skin -points.
