 (Blepharoceridae Loew, olim), 



C. JR. Osten Sacken. 



The scope of the present paper is principally crrtical. Since my 

 Short article in the Berl. Ent. Z. 1891 (Synopsis of the flescribed 

 genera and species of Blepharoceridae) and even earlier, I have 

 had bot little opportunity for continuing my studies on this faniily 

 in nature, or even in coUections, but I have not ceased to keep up 

 with its progress in entomological literatnrc. A critical survey of 

 recent, as well as of older publications, has afforded nie some results 

 which T deeni worthy of communication.

 l)revity's sake, give the author's name, and the date and pagc of
