moths which I have described. They are of about three times 

 the thickness of those in similis and clirysorrhoea and they 

 appear to be covered with projections which may be described 

 as resembling saw-teeth regularly arranged along their entire 

 length. 



There are no spicules so far as I have been able to discover. 

 I may say that I am going into the whole matter more 

 minutely and hope to have something more to say about it on 

 a future occasion. 



The cocoons of the African Lasiocampid moth Chryso- 

 PSYCHE VARiA, Walk. — Professor PouLTON exhibited the 

 imagines and cocoons of G. varia sent to him by Dr. G. D. H. 

 Carpenter from Damba Island, 20 miles south-east of Entebbe. 

 The larval skin was still projecting from some of the cocoons, 

 and showing its blue spots. The larvae had spun up November 

 12, 1911, and the moths emerged December 13. 



Dr. Carpenter had written, April 18, 1912, from Bugalla, 

 one of the Sesse Islands : — 



" The cocoons of Imago Z> 137 \Chrysopsyche varia] are par- 

 ticularly interesting. The larvae are gregarious, resting freely 

 exposed on the tree trunk by day, at sunset going up in a proces- 

 sion to feed. When full-grown they are chocolate brown with 

 blue patches and patches of glistening white short hairs — very 

 conspicuous. The cocoon, when finished, has a hole at one end, 

 through tvhich the lavval shin is partly pushed out at pupation, 

 and projects, showing the bright blue patches. Now as the moth 

 makes a hole at the other end for its exit, the only explanation 

 is that the aposematic larval skin is made use of to protect the 

 pupa ! I know of no other cocoon in which a hole is left 

 especially for the extrusion of the larval skin. The cocoons 

 are not especially exposed, in fact I had to search to find 

 them : they were in a sheltered nook under fallen branches 

 and amongst projecting roots. I left the larvae on the tree 

 as they would not eat in confinement, but just wandered round 

 and round the box in single file, head to tail, forming a com- 

 plete ring, and looking very absurd ! Evidently they wanted 

 the stimulus of climbing up the tree to make them eat." 



Professor Poulton said he had no doubt that Dr. Car- 

 penter's interpretation was correct. It required a very
