narrower than the third segment, which segment is 
swollen on each side into a lateral hump ; the remaining 
segments are of about equal width until the twelfth 
is reached, on which there is a slight dorsal ridge ; the 
segmental divisions tolerably distinct. The skin along 
the sides rather puckered; the fourth segment is 
swollen ventrally, which makes the third pair of legs 
appear longer than the rest. The ground colour is 
dull reddish-brown; from the tenth to the thirteenth 
segments reddish-ochreous, and the sixth, seventh, 
and eighth segments dull dirty black. Head pale 
ochreous-brown, spotted and marked with dark brown; 
medio-dorsal line dull dark green ; subdorsal stripes 
dark brown, with indistinct paler central line; 
there are no perceptible spiracular lines. Just above 
and a little in front of the first pair of claspers is an 
ochreous-yellow mark, and on the seventh and eighth 
segments, just below the dorsal line, is a pale grey 
lateral mark. Spiracles small, greyish-brown, encircled 
with dark brown. The ventral surface is dark purplish- 
brown, with ochreous-yellow medio-ventral stripe. 
These twolarvee were much darker and redder than a 
brood I had reared to moderate size the year previous, 
which were much more nearly like the pale greyish 
variety of the larva of 7. crepuscularia. Probably 
the larvee of 7. biundularia vary as much as do those 
of that species. (George T. Porritt, April 8th, 1873;

T'BPHROSIA EXTERSARIA. | 
Plate CXIII, fig. 4. 
When on a collecting expedition to Abbott's Wood, 
Sussex, with Mr. W. H. Tugwell, at the beginning of 
June, 1892, we found Tephrosia extersaria a very 
abundant visitor to the sugared trees. From some of 
the specimens boxed eges were obtained, but it was 
not until some time after they were hatched that I 
discovered there was no English description of the
