CiCADrLA LITIDA, n. S. 



= cyanw, Edw, {ante vol. ii, 2i3d Ser., p. 33, excl. syn.). 



The following is a statement of the circumstances under which the above cor- 

 rection has become necessary. Mr. E. A. Butler wrote me some time since that he 

 had found Cicadula eyancs, and on examining some of his specimens it was at once 

 apparent that his insect was not the same as mine. My insect is a true Cicadula, 

 with the head wider than the pronotum, the sides of the latter exceedingly short, 

 and the genital plates of the male attenuate and upturned at the apex, whilst it 

 agrees in point of colour with the description of Boheman's cyanm. Mr. Butler's 

 insect, on the other hand, is as much a Thamnotettix as T. spendidulus, Fab., which 

 it closely resembles in size and shape ; its head is narrower than the pronotum, the 

 sides of the latter are as long as the hind margin of the eye, the yellowish fusco- 

 hyaline elytra have (in life) an evident blue bloom, which is retained to a certain 

 extent after death, and the upper branch of the cubital vein runs into the upper fork 

 of the lower branch near the middle of the elytron. 



After reading Tollin's remarks (Stett. Ent. Zeit., xii, p. 69) I have 

 a strong impression, which I record for what it is worth, that C. livida, 

 onilii, is the same as his lassus onorio. 



Thamnotettix ctak^, Boh. 

 {vide supra). 



Several females were taken by Mr. E. A. Butler at Loughton and 

 Fifield on Potamogeton natans. The determination of our insect as 

 Boheman's species is confirmed by Dr. Puton, M. Lethierry, and Dr. 

 J. Sahlberg, the latter kindly giving me an identical specimen taken 

 in East Gothland by Haglund. 



LiMOTETTIX 5-NOTATUS, Boh. 



This species occuri'ed to me very sparingly at Ranworth in September and 

 October, 1890. It may be distinguished from L. intermedins, Boh., our only other 

 species in which the sub-ocellar black spots on the crown are minute and punctiform, 

 by the want of a black spot on the temples and (in most specimens of the male, at 

 least) by having in the middle of the front margin of the crown a pair of very short, 

 fine, geminate, longitudinal, black lines ; the deep yellow colour of its upper-side 

 and the two black spots on the forehead sufficiently distinguish it from Zi. sulphurellws . 

 I managed to select a few specimens out of swarms of L. 4:-notatus, from which it 

 may be distinguished in the net by its larger size, difPerent colour, and the want of 

 the large black spots on the crown. 



Cicadula Dahlbomi, Zett. 



In June, 1892,1 discovered this fine and interesting species on an isolated patch 

 of Epilobium any usti folium in Hilcot Wood near this place. Its food-plant is
