CLINORHYNCHA H. Lw. 



This genus, first recognized in this country by the author, is an 

 extremely interesting form and distinguished at once by the great 

 prolongation of the mouth parts and the lo to 12 segments of t'.\e 

 antennae. The European C . c h r y s a n t h e m i H. Lw. has 

 13 antennal segments in both sexes. The wings are also rather 

 peculiar [pi. 34, fig. 7] . The species are all small, being only about 

 I mm in length. 



The European C. m i 1 1 e f o 1 i i Wachtl. was reared from ap- 

 parently normal flowers of Yarrow (Achillea millefolium) 

 and it is probable that the otner species known to occur in this 

 country, have similar habits, particularly as all European forms, so 

 far as known, have been bred from flowers of the Compositae.
