du 3 e stade larvaire de Phormia est particulièrement riche en peptides basiques L 

 tandis que les extraits larvaires de Drosophila ne contiennent que des peptides 

 acidiques. 



SUMMARY 



Ninhydrin — positive fractions of larval hemolymph of Phormia regina and 

 Drosophila melanogaster were separated by high voltage paper electrophoresis. 

 By combining ninhydrin coloration and Rydon & Smith's (1952) iode — starch test, 

 it has been possible to détermine the distribution of peptides and amino acids 

 on the same pherogram. The results corroborate those obtained by paper- and 

 ion-exchange chromatography : the 3rd larval stage hemolymph of Phormia is 

 particularly rich in basic peptides while Drosophila larval extracts contain only 

 acid peptides.
