PREFACE 



The insects which form the subject of the present paper , 

 were collected by Prof. Odoardo Beccari, principally in Celebes, 

 Ternate, Amboina, New Guinea, the Aru Islands (1873-75), 

 and in Sumatra (1878) ; by M/ L. M. D'Albertis in New Guinea 

 (1872 and 1876-77) and by M/ G. B. Ferrari in Java (1875). 

 They belong to the Museo Civico in Genoa. 



In accepting the flattering proposal of the authorities of the 

 Museo Civico to describe this collection, I undertook a task 

 which was somewhat above my level, as my dipterological stu- 

 dies had hitherto been confined to North American diptera, and 

 especially to a limited number of families of that order. Ho- 

 wever, I have been able to compensate in a measure my defi- 

 ciences in knowledge and experience, by means of the facilities 

 for travelling , which I enjoy , and which enabled me to com- 

 pare the types of a large number of the species I had to 

 pame.
