Cerocomae, Mylabres and Zonites 



Any lingering doubts may be dispelled: by 

 good fortune, a friend of mine, Dr. Beaure- 

 gard, who is preparing a masterly work upon 

 the Blister-beetles, had some pseudochry- 

 salids of Schreber's Cerocoma in his possess- 

 ion. Having visited Serignan for the pur- 

 pose of scientific investigations, he had 

 searched the Tachytes' sand-heaps in my 

 company and taken back to Paris a few 

 pseudochrysalids of grubs fed on Mantes, in 

 order to follow their development. His at- 

 tempts, like mine, had miscarried; but, on 

 comparing the Serignan pseudochrysalids 

 with those of Schreber's Cerocoma, which 

 came from Aramon, near Avignon, he was 

 able to establish the closest resemblance be- 

 tween the two organisms. Everything there- 

 fore confirms the supposition that my dis- 

 covery can relate only to Schaeffer's Cero- 

 coma. As for the other, it must be elimi- 

 nated: its extreme rarity in my neighbour- 

 hood is a sufficient reason. 



It is tiresome that the diet of the Aramon 

 Meloid is not known. If I allowed my- 

 self to be guided by analogy, I should be in- 

 clined to regard Schreber's Cerocoma as a 

 parasite of Tachytes tarsina, who buries her 

 hoards of young Locusts in the high sandy 

 banks. In that case, the two Cerocomae
