in some kinds of fungus as can well be imagined." As those 

 figures do not present any very striking fungoid characters, I 

 think he must have meant plate 46, where figures 1 to 4 

 represent organisms similar to those found on some Satyrids. 

 Prof. Smith goes on to say that he has " found his (Mr. Scudder's) 

 pictures in every case absolutely correct." 



Figure 4 on plate 44 represents a portion of the wing of 

 Speyeria idalia ; the objects in this figure that Mr. Scudder 

 terms " feathered androconia " are really the rhizoids of a 

 fungus, either represented from the under side, or ehe showing 

 through the transparency of the overlying scales. Figures 39 

 and 40 of plate 46 are said to represent the androconia of Pieris 

 oleracea and P. rapce, but both figures are taken from mutilated 

 or imperfectly developed examples. Of figure 40 (rapce) I can 

 speak positively from my own observation ; whilst the oleracea 

 example so closely resembles the parasite of P. napi, that I have 

 not the least doubt of its imperfect condition ; certainly, many 

 examples, both of the rapce and napi forms, minus their sporo- 

 carps, have come under my notice ; but I have invariably found 

 some on every slide examined in which this organ, the most 

 important part, was developed and in situ. Figure 42 of the 

 same plate is said to represent the androconia of Laertias 

 r)hilenor ; this form differs from all the others figured by Mr. 

 Scudder, and, speaking with reserve, I must say that in my 

 opinion it represents an imperfect example. One would hardly 

 suppose the vertical lines represented the stride of an ordi- 

 nary scale ; neither do they ; one of these lines represents the 

 stem that bears the sporocarp, the remaining four are the ribs 

 or paraphyses (figure 1). I have very little doubt that the figure 

 represents the basal portion * of the peridium, the stem and 

 sporocarp of a fungus nearly allied to that found on P. afiathina 

 (see a7ite, p. 171). Similar mutilated examples of the agathina 

 fungus have come under my notice (figure 2). 



My efforts to learn something of the later phases in the 

 development of the rapc^ fungus were only partially successful ; 

 the first male of this species procured this year had never used 

 its wings in flight, its fungi presented some abnormal appear- 

 ances. Nearly all possessed the sporocarp ; some had no lobes, 

 some only one, but the greater number had both. The most 

 numerous and most instructive examples were those which 

 possessed horn-like processes arising from the apices of the inner 

 sides of the lobes ; these " horns " varied in length, from a mere 

 point to about one-third the breadth of the fungus ; they are 

 probably re-absorbed, as there was no indication of their dehis- 

 cence ; their function undoubtedly being to afford protection to 

 the growing sporocarp. The examination of the wings of an 

 example immediately after emergence, and of several dissected
