Frauenfeld (A^erh. zooL-bot. Ges. in AVieu, I3d. xiv. pp. 383, 384) describes 
the occurrence of peculiar supposed eggs of some species of insect found 
attached to the frond of an Australian fern (Asplenium, sp.). From their 
characters, Frauenleld thioks they must belong to some Orthopterous insect. 
The same author reports on some insects destructive to plants, sent to him 
by Prince Colloredo-Mannsfeld (A^erli. zool.-bot. Ges. in A\4en, Bd. xiv. 
pp. 413-416). The larva3 sent are the wireworm, the larva of a Silj^ha (the 
injurious character pf which is doubted by Frauenfeld), both said to infest 
beetroot, and the fornier to have lately attacked the maize. A third species 
is Chlorops strigula (Fab.). Frauenfeld has some remarks upon other inju- 
rious Dipterous insects. 
Kiinstler (Verh. zool.-bot. Ges. in AVien, Bd. xiv. pp. 770--784) describes 
the ravages of several injurious species of insects, in continuation of former 
communications. The insects here referred to are — Cecidomyia destructor 
(Say), Chlorops strigula (Fab.), Anthomyia radiciitn (JAnii..'), Bostrichus curvi- 
dens (Germ.), Cryphalus ahieiis (Rtzb.), Xyloteres lineatns (Gyll.), B(daninus 
turhatus (Schdnh.), Luperus costulatus (Schauf. MS.), Anomala vitis (Diift.), 
and Simaethis nemorana (IJiibn.). 
Loew (Berl. ent. Zeits. 1864, pp. i-x) Las publisLed an ela- 
borate report on tlie viviparous larvae observed witliin tlie last 
four years. The larva discovered by AA^agner be regards as be- 
longing to the family Cccidomyidce ; Wagner Las since obtained 
the perfect insect and observed its sexual rej)roduction, as stated 
to the Academy of St. Petersburg by Von Baer, but the details 
of Lis observations Lave not yet reached this country. Meinert, 
however. Las discovered a viviparous larva very similar to 
Wagner^s, and described it and its perfect insect in Kroyer^s 
Tidsskrift,^ vol. iii., under the name of Mias tor metraloas. 
The insect belongs to the family Cccidomyidce y but presents 
(according to Mcinert^s description) several highly exceptional 
characters, such as two-jointed palpi and four-jointed tarsi; 
Loew suggests that a careful examination may perhaps prove 
that there is some error in this. He thinks the genus will be 
most nearly allied to Spauiocera, IjOcw also refers to the vivi- 
parous larvic discovered by Pagcnstcchcr in the deeaying refuse
