JQ^ [October, 
When this species was made out I had not Flor's work before me: 
the perusal of his description makes me now rather doubtful as to the 
correctness of the identification. Fallen's diagnosis (with which my 
13 specimens agree) is as follows : — " Viridis, supra immaculata ; capitis 
apice obtusissimo [i. e., as compared with Pedmpsis] ; alls albicantibus. 
G. punctata vix minor. Supra virescens, nitida, post mortem flavescens. 
Caput impunctatum [i. e., without black spots]. Antennae longiusculse. 
Elytra corpore longiora, exalbida ; nervis tenuibus, viridibus. Abdomen 
supra atrum, subtua ssepe virescens. Tibia? nigro-punctatse." Flor 
mentions a black dot upon the gena?, which I cannot discern, and 
speaks of variations which my examples do not present. 
This species is from an osier bed on the banks of the Soare, near 
Aylstone, Leicestershire. It difiers from 4i-notatus, Fab., in the longer 
vertex, narrower and longer body, abdomen only black in the middle 
above, coloiir after death more ochreous, and absence of black spots on 
the frons and vertex.

Statura praecedeutis. Pallide viridis, capite magis flavo. Abdomen 
(J nigrum ; 5 nigrum, flavo-marginatum. Vertex pronoto quadrante 
brevier, porrectus, apice rotundato. Maculae duse verticis, duseque 
frontis, rotundse, nigrse : posteriores nonnunquam parvae, — sed caput 
aliquando immaculatum. Sub antennarum insertione, in genis, punctum 
nigrum ; facies tota saepe linea tenui nigra circumscripta. Antennarum 
articulus 2"' plerumque niger. Hemelytra pellucida, nitida, viridia, 
nervis flavis. Pedes flavi ; tibiae posticae nigro puuctatae et lineatae ; 
coxae saepius, femora raro, fusco-notata ; femora antica extus, postica 
intus, linea nigi-a, — saepissime obsoleta. (J ? .

This* species is less common than sexnotatus, but still sufficiently 
abundant in damp grassy places throughout the kingdom. 
{To he continued.') 
* The above insect, and many others of the smaller and softer Cicadas (ex. gr., Veltocephalus, 
Bupteryx), are often infested by an oval parasite, destitute of limbs, and immoveably attached to the 
abdomen or sides of the pronotum by a peduncle The parasite first appears on the young larva, and is 
then jiale coloured, but grows with the growth of its victim, and finishes by becoming black. The 
Cicada is often mrilformed, owing to the constant presence of this eicrescence, equal in size to its own 
head, but which does not appear to cause death. I have observed this fact a hundred times; and have 
read accounts oi it in books, but nothing satisfactory. — T. A. M.
