Since the publication of my former notes in the Trans- 

 actions of this Society (1898, pp. 75-82), a great advance 

 has been made in our knowledge of these minute insect 

 forms, not only with respect to the insects themselves but 

 also with regard to their life histories. With the latter 

 side of the subject I do not propose to deal here at all, 

 but would refer to the exhaustive list of publications given 

 in Ulmer's Memoir " Uber die Metamorphosen der Tri- 

 chopteren " (Abhandlungen aus dem Gebiete der Natur- 

 wissenschaften, heraus : vom Naturwissenschaftlichen 

 Verein, Hamburg, Bd. xviii). 



The object of my notes, in addition to the primary one 

 of giving descriptions of two new species, is to call attention 

 to the species which have been described since my former 

 paper, and also to give further details wliich have since 

 been ascertained regarding the geographical distribution 

 of some of the species. For material beyond the results 

 of my own collecting, I am indebted to Professor Klapalek, 

 Dr. Fr. Ris, and especially to Herr A. J. Silfvenius of 

 Helsingfors, from whom I received a most extensive 

 collection of Hyclroi')tilidi& for examination. 



Agraylea multipunetata, Curt. 



Seen in great quantity from several Finni.sh localities. 

 I have taken it in Xorway. 



A. cognateUa, McL. 



This is a critical species. One example taken by myself 

 in Norway, I have referred to this species, but in the large 

 collection sent from Finland by Herr A. J. Silfvenius, 

 including material both dry and in alcohol, there was none 

 that I could separate satisfactorily from A. multipunctata.
