were taken in June and July, i88g, and which were referred 

 to in his paper on "The Pupation of Cossns li^nipevda''' 

 (" Proc. S. Lond. Ent. S.," 1900, pp. i — 5) . When found, the 

 pupa was protruding about half its length from the hole, 

 which it exactly fitted, in the side of the board forming 

 the skirting at the bottom of the fence. Evidently the 

 larva had sought the rotten part of the back of the board for 

 forming its cocoon, and the pupa had forced its way through 

 the thin surface of the board in order to assume the position 

 suitable for the emergence of the imago. Several recently 

 vacated empty pupa-skins were also found at about the same 

 date, in positions similar to those described in the paper 

 above referred to. 



Mr. Step exhibited a rare fungus {Atiricidaria lohata) which 

 he had found at Ashtead, on an old stump. There is only 

 one other British species of the genus, A. mesentcrica, which 

 is met with much more frequently. 



Dr. Chapman exhibited specimens oiHyhocampa (Notodonta) 

 dryinopa received from Mr. Dodd, Queensland, with some 

 H. milhaiiseri for comparison, with cocoons, etc. Mr. Dodd 

 has some notes on the habits of the species in the " Entomo- 

 logist," 1902, page 42. 



The species, in appearance and also in habits, is obviously 

 very close to our European Hyhocampa milhaiiseri. The 

 similarity of the imagines is very close ; so also are the eggs. 

 The larva has the same bizarre aspect as that oi milhauseri ; 

 it has the same dorsal process on the first abdominal seg- 

 ments ; the latter segments are more like those of Staitropus 

 fagi than H. inilhauseri, but agree with both, and with the 

 Ceruras in wanting the claspers. 



The cocoon is more like a C crura than that oi H. inilhauseri 

 is, containing many chips of various sorts like they do, instead 

 of being pure, gummy silk, like if. uiilhauseri uses. The pupa 

 resembles that of milhauseri in having a frontal spike — this 

 double and more prominent than that of inilhauseri, which 

 springs from the bottom of a depression. Both use this 

 spike for making an opening in the cocoon for the escape of 

 the moth. Milhauseri (see " Entomologist," i8go, page 92) 

 actually, with it, cuts out an oval lid by passing the spike 

 round and round the line of section, applying a softening 

 fluid along the line and cutting through the silk as it softens 

 till the lid is cut out. Dryinopa acts differently (the chips 

 of wood, bits of stone, etc., would prevent the process that 

 inilhauseri can use in the pure silk), but actually, apparently 

 without the use of softening fluid (but of this I am not sure),
