ENTOMOLOGY HEMIFTERA. 397 



With respect to the apocryphal luminosity of Fulyora candelaria, Bowring 

 has observed in China the Lantern-flics, both at large and in captivity, without 

 having ever perceived them to give light. (Ann. Nat. Hist, xiv, 427.) The 

 insect flies well, and is particularly lively in the twilight. The same is the 

 case with our F. europea. About the same time a word has been again said 

 in favour of the luminous faculty of the Brazilian F. la fern aria ; Spinola 

 (Rev. Zool. p. 240) communicates the intelligence that a traveller named 

 Kaffer professes to have seen one of these Lantern-flies give light. 



CICADELL.E. White (Ami. Nat. Hist, xiv, 245) has characterized a new 

 genus nearly allied to Ledra, Ledropsis, with the head elongated in front, 

 the eyelets (ocelli) iii a line with the eyes, the corslet simple, the hind shanks 

 serrated beliind and not enlarged. The species, L. cancroma, is from Hong- 

 Kong. Cercopis bispecitlaris, White (ibid. 426), from Hong Kong, is a 

 species often received from China. 



Fieber (Eutom. Monogr. 7) has illustrated the German species of the 

 genus Cercopis, of which he distinguishes these four : 1. C. mdnerata, 111., 

 found in mountainous parts of Bohemia, Austria, Cariuthia, Illyria, and 

 Bavaria. 2. C. mactata, Germ., common in orchards, grass-plots, woods, 

 and meadows. 3. C. arcuata, a new species, from the central and outer 

 ranges of the Bohemian mountains. 4. C. sangidnolenta, L., a native of 

 Southern Germany and the basin of the Mediterranean. The third species 

 agrees with the fourth in the narrow markings on the half-shards, but with 

 the other two in having the legs entirely black. 



STRIDULANTIA. White (Ann. Nat. Hist, xiv, 426) has described a new 

 species, Cicada (Moryannia) nasalis, from Hong Kong. C. sanffuinea, Deg., 

 and C. sanguinolenta, F., are also found there. 



APHIDES. R,atzeburg(Forstius, iii, 195) has made additions of moment 

 to what has been known of this family. [Elegant figures are given of many 

 of the species. As a fourth (and new) species of the elm, inhabiting the 

 imbedded woody galls of the leaf midrib, he has given Aphis alba (p. 222, 

 pi. 13, f. 3.) This is the Tetraneura described as Eriosoma (Byrsocrypta) 

 pallida, in Ann, Nat. Hist, ii.] 



He has also stated his ideas concerning the multiplication and generation 

 of these insects (Entom. Zeit. p. 9), in consequence of having observed a 

 species on a birch tree, which continued to produce a living progeny from 

 August on into the winter, without either males or females appearing. 



Bouche and Kaltenbach (ibid. 81 and 133) hereupon have remarked 

 that the males in this family arc not always winged, and may therefore 

 easily be overlooked. The question, however, iu this case, has been solved 

 in another way, as Ratzebnrg, having continued his observations, succeeded, 

 the May following, in Gliding the winged females, and subsequently, in 

 October, winged males also, and these paired (ib. 410.) He was enabled 

 thus to identify the species as Aphis oblonga, Heyden.
