EUPTEEYX SIGNATIPENNIS. 117 



to the segments. Genital valves of the female bright 

 yellow. 



This insect, up to quite recently, has been con- 

 sidered rare. Mr. Marshall some years ago took it at 

 Milford, and Mr. Douglas also in the neighbourhood of 

 London. Probably, if search be made, it is not, after 

 all, so very uncommon. 



In the month of October, 1889, I saw several exotic 

 pot-ferns growing in the hothouse of Dr. Tyacke, in 

 Chichester, the fronds of which were speckl'ed with 

 white dots, obviously the punctures of an insect. The 

 gardener captured several small Typhlocybidis from 

 these plants, and he assured me that they made the 

 ferns yellow and sickly. As many as fifty specimens 

 might sometimes be found infesting a single plant. 



An examination of the wing-veining proved the 

 genus to be Eupterijx ; and I have no reasonable 

 doubt that, notwithstanding the presence of two pale 

 fuscous strigae on each elytron, the insects were £". 

 Jilicum, as above described. My figure is from Mr. 

 Douglas's cabinet, and probably is a little faded. I 

 have several specimens in my cabinet. 



Length with wing, 0'14 inch, or 3 50 millimetres.
