REPORT ON ZOOLOGY, MDCCCXLII : 
D. nervosa, of the Berlin collection (Stoll, f. 160), and two new species ; 
D. semistnata and strigipennis, from Brazil. 
A second genus, Mysidia, is formed of those species from South 
America which have a slighter form, shorter legs, a proboscis not 
reaching beyond the hind legs, moderately long antennae, shorter and 
broader dusty wings. In this are D. pallida, F., Perch. ; squamigera, 
costalis, punctum, testacea, nivea, F. ; and three new species : M. albi~ 
pennis, from Mexico (Vera Cruz) ; M. lactijlora and suhfasciata, from 
Brazil. — Diospolis, Westw. (formerly Lydda, Westw.), is a New Holland 
form, with a shorter proboscis, short antennae, and long anterior wings, 
very narrow and rounded at the point : D. elongata, F., is the only 
species known, and is from New South Wales. — Thracia, Westw., with 
long antennae (double the length of the head), three keels on the clypeus, 
and very long narrow anterior wings, truncate at the point, is founded 
on D. sinuosa and nervosa {Bohemanni, Westw.), Bohem., from 
Sierra Leone, to which is appended a Javanese species, Thr. javanica. 
— Phenice, Westw., comprehending H. fritillaris, fasciolata, and stel- 
lulata, Bohem. ; clypeus as in the preceding ; antennas short ; shorter 
anterior wings rounded at the point ; also differing from all the preceding, 
by its longish remarkably emarginated eyes ; ocelli distinct. — A couple 
of very small and extremely tender insects, from St. Vincent’s, in the 
West Indies, approaching the genus Anotia, Kirby, form the genus 
Patara, Westw. ; eyes large, emarginated beneath ; ocelli indistinct ; 
very large warty second antennal joint ; P. guttata and albida, Westw. 
— CencTirea, Westw., has large eyes emarginated beneath, below them 
are distinct ocelli ; small antennae with a roundish tuberculated second 
joint: one species C. dorsalis, Westw. — Lastly (ibid. p. 20) Zeugma 
is characterized, which, by its wing veins, occupies a position between 
Derhe and Mysidia, but (judging from the plate) differs by the keels of 
the forehead continuing on to the clypeus, and the posterior tibiae having 
a spine in the middle : one new species Z. vittata, of unknown native 
country. 
MEMBRACiDEiE. — One new species, Smilia informis, from Brazil, has 
been characterized by Westwood (Ann. Nat. Hist. ix. p. 119). 
CiCADiED^. — Eversmann (Bull. Mosc. 1842, p. 797) has given a 
notice on the dropping willows of Orenburg. The cause of the drops 
was the larvae of an Aphrophora, which very much resembled the A. 
spumaria, but was more oblong, and of a uniform yeUow-grey. He 
names it A. lacrymans ; it is, however, distinguished by Fallen, as 
A. salicis. 
The reporter (Arch. 1842, i. p. 285) has described Aphrophora albi- 
cincta, and Eurymela hicincta, from Van Diemen’s Land.
