Euzenilliopsis diatraeae, Towns., a Tachinid parasite of the sugar- 

 cane borer, Diatraea saccharalis ^ crambidoides, Grote, has been 

 imported from Cuba and liberated In certain fields of Louisiana, where 

 it has apparently become established. With the aid of additional 

 importations it is hoped ultimately to supply every plantation with 

 parasites. As hving parasites in the pupal stage were found in the 

 field on 13th December after being exposed to a temperature of 

 35° F., there is every reason to believe that this fly will withstand 

 the chmate of Louisiana. 



Metcalf (Z. p.). a Suggestion for a better Popular Name for the 

 Fulgoridae (Hemip.). — Entom. News., Philadelphia, xxxi, no. 2, 

 February 1920, pp. 57-58. 



The only popular name apparently hitherto used for members of 

 the family Fulgoridae is " lantern flies," based upon the supposition 

 that a large South American species emits hght. As this is not a. 

 general characteristic of the family, the term is evidently a misnomer. 

 The author suggests " plant-hopper " as being the most suggestive 

 name available, thus bringing the family into hne with the closely 

 related families known as tree- hoppers (Membracidae), frog-hoppers. 

 (Cercopidae), and leaf-hoppers (Cicadellidae).

A further account is here given of the entomogenous fungus, 

 Sorosporella uvella, infesting cutworms [R.A.E., A, v, 484]. It is 

 shown that the yeast-hke vegetable cells existing within the blood 

 of infected insects are ontogenetically related to other phases in the 

 development of the organism. These cells are ingested by certain 

 of the blood corpuscles, the process of phagocytosis apparently being 

 followed by the destruction of the phagocytes. The organism is 

 readily cultivated on artificial media, and tests were made on cut- 

 worms infected with S. uvella and on Bonibyx mori (silkworms) and 

 Lachnosterna spp. (white grubs) inoculated with the conidia. A 

 hypodermic needle was used, for when the usual methods of infection 

 were employed the insects in question did not succumb. To determine 

 whether there is immediate active phagocytosis of infected susceptible 

 hosts, the conidia were injected into Xylomyges {Prodenia) eridania. 

 Cram, (semitropical army worm). Phagocytosis was not observed 

 within two days after inoculation, but smears made three days after 

 injection showed blastocysts incorporated in the phagocytes, though 

 no sign of disintegration of the former could be detected, while the 

 fungus cells were reproducing rapidly. 



Other insects inoculated, either by direct contact, by spraying or 

 by feeding, include larvae of Musca domesiica and of Elaterids, 

 nymphs and adults of grasshoppers, workers of the termite, Reticuli-
