LI. — Researches on the Nervous System of the Larvce of 

 Dipterous Insects. By Prof. Ed. Brandt. 



Having received from M. Behling a number 'of Dipterous 

 larvse belonging to families which had not been previously 

 examined as to their nervous system, I took the opportunity 

 to dissect them, and with the following results. 

 I have examined the following : — 



Leptid^ : Leptis, sp. 

 BiBlONlDJi : Bihio Marci, L. 



Pomonw, Fabr. 



fei'ruginatuSj L. 



varipes, Meig.
