The Glow- Worm and Other Beetles

 "Eureka!" 



On the days that followed, a serene and 

 balmy sky enabled the Anthophorae to leave 

 their retreats and scatter over the country- 

 side and despoil the flowers. I renewed my 

 examination on those Anthophorae flying 

 incessantly from one flower to another, 

 whether in the neighbourhood of the places 

 where they were born or at great distances 

 from these places. Some were without 

 Sitaris-larvae; others, more numerous, had 

 two, three, four, five or more among the 

 hairs of their thorax. At Avignon, where 

 I have not yet seen Sitaris humeralis, the same 

 species of Anthophora, observed at almost 

 the same season, while pillaging the lilac- 

 blossom, was always free of young Sitaris- 

 grubs; at Carpentras, on the contrary, where 

 there is not a single Anthophora-colony with- 

 out Sitares, nearly three-quarters of the 

 specimens which I examined carried a few 

 of these larvae in their fleece. 



But, on the other hand, if we look for 

 these larvae in the entrance-lobbies where 

 we found them, a few days ago, piled up in 

 heaps, we no longer see them. Conse-

 opened their cells, enter the galleries to
