100 Mons. J. Bourgeois on Ulalacodermata 



[see below]. It is common here, in certain nights or states 

 of the weather, and perhaps at least foretels fair weather for 

 that night. Its light is at intervals, and only (as in all the 

 genus) when tljing. When taken it emits and withdraws its 

 light much more rapidly ; as [it] seems as if the effect of 

 breathing, whereas in flying the light and dark intervals are 

 both much longer (abt 5 seconds more or less). 2. 3. [29]." 



Burchell had captured what he took to be the larva of 

 P. lineola on March 1, 1829, in his garden at Porto Real. 

 The following note refers to it. Tiie specimen itself has not 

 been found. 



"1330. Larva of {Lamp^n's?). Caught in the garden 

 crawling on the ground at night, and detected by means of a 

 small spot of light at the head ; but on being touched it 

 instantly emitted a much stronger light from every part or 

 joint of the abdomen which previously was quite dark. The 

 light proceeded only from the underpart : the back was dark 

 at all times. 1. 3. [29]." 



The sudden increase of light which follows disturbance 

 strongly supports A. R. Wallace's interpretation of the 

 luminosity of glow-worms as aposematic]
