little village of New Harmony who knew about Say, and who were dis- 

 tinctly of the opinion that his residence in their village sheds lustre on its 

 history. The village library is an admirable one, housed in a beautiful 

 building, and among the treasures of the library are certain of Say's manu- 

 scripts, among others, one written upon the day of his death. — L. O.

NOTE ON THE GENERIC TITLE TRIFURCULA. 



BY A. RADCLIFFE GROTE, HILDESHEIM, GERMANY. 



In my "Descent of the Pierids," Jan., 1900, I have used Tri/urcu/a, 

 Staud., Iris., VII., 56, for a genus of Andean Pierids, but this name is 

 preoccupied in the Lepidoptera by Zeller, 1848, Staud. & Rebel, Cat. II., 

 p. 221. 



Staudinger states (1. c.) that he had at first named the genus 

 Piercolias, so this name, though open to criticism, should be used for 

 the Pierid genus with the type huanaco, Staud. The morphological 

 value of the neurational character of the primaries of Piercolias, which 

 led Staudinger to choose the name Tri/urcula, does not seem to have 

 been appreciated by him. The gradual progress of R2 towards the 

 apices, and of M2 towards the Radius, brings these branchlets in 

 juxtaposition. 



SPINNING METHODS OF TELEA POLYPHEMUS. 



In reply to the query suggested by Prof Grote, in the April 

 number of the Entomologist (page iio), with reference to the spinning 

 methods of Telea, I have discussed the subject with Dr. Fletcher, 

 whose opinion is that only some of the cocoons are so suspended, but 

 recent search has decided me that in this locality this is the case with 

 the majority. 



On April 2nd I found two cocoons on a small willow bush, one 

 suspended, with the leaves firmly attached to the stem ; the other 

 had been sjum between the overhanging sides of a large leaf that 

 had fallen across the limb, thus forming a complete canopy, but the 

 cocoon was firmly fastened to the twig with a lot of silk. Diligent 

 search amongst the leaves on the ground failed to reveal any fallen 

 cocoons. On April 8th I found two cocoons, both suspended on a wild 

 currant bush, and though there was a pile of dry straw lying against th?
