LIST OF NORFOLK SAWFLIES. 
PiiYLLOTOMA FUMiPENNis. Cam. This is a new species which 
I took at Brundall on alder, May 12th 1878. 
I met with but one specimen, as I could not 
make it agree with any description I could find, 
I sent it to Mr. Cameron, who said it was new, 
and named it (E. M. M. xxiv.). 
Genus Fensua. Leach. 
Fenusa melanopoda. Cam. I used to take this freely on alder 
in the Heigham Osier Car in July. 
„ PUMiLio. Htg. Taken in May and August at Norwich. 
,, PYGM/EA. Klug. I have taken but two specimens of 
this one at Earlham, the other at Lynn in June. 
„ PUMiLLA. Klug. Norwich, I have bred this from the 
leaves of the birch. 
„ ULMi. Sun. Common in Tuckswood Lane, near 
Norwich, the end of May and June. 
Genus Athalia. Leach. 
Athalia ancilla. Lep. Not uncommon in June. 
„ SPINARUM. Fab. This pest destroyed many thousand 
acres of turnips in 1782. The earliest record of its 
appearance is 1756, they appeared at intervals up 
to 1838 or 1839, since which time it certainly has 
not caused the damage it formerly did. I do not 
know if it has been recently taken at all (for 
furtlier particulars see Curtis’s ‘Farm Insects,’ p. 39). 
„ ROSyE. Lin. Very abundant everywhere. 
„ LUQENS. Klug. Far from common at Brundall in May 
and August, and perhaps the intervening months. 
Tribe Nematina. 
Genus Hemichroa. Ste. 
HeiMICHROa alni. Lin. Common on alder in June. The male is 
very rare. I have twice bred this sex. 
„ RCFA. Panz. Appears to bo far from common. I have 
only bred one female from larva taken near 
Norwich. 1 was fortunate enough to breed 
a male from larvfe I took at Wimbledon. This 
sex is exceedingly scarce.
