FIBEFLIES—TBINKOMALI

of the light as 100, 104, 90, 86 per minute. It was then put into 
the cyanide-bottle; in about half a minute, before the death of the 
insect, its light became constant; in four minutes the light was very 
faint, in five minutes it was extinct. 
Fire-fly B was also very active; four counts gave the rate of 
flashing as 116,122,106,102 per minute. It was then chloroformed; 
within about twenty seconds the light had become almost constant, 
in three minutes it was faint, in four minutes extinct. 
A short halt some 25 miles short of Trinkomali, in a delightful 
part of the forest, where the trees were much finer than usual and 
the roadside grass of more interesting character, yielded only Crastia 
asela, Tirumala septentrionis, a male with a pleasant scent, and a 
“ wet ” Terias hecabe. Grubbing among dead leaves unearthed the 
brilliantly shining Phytophagid beetle, Corynodes dohrni , and a second 
specimen, an apterous female, of the fine scarlet and black shining 
Bug Physorrhynchus linnaei ; it has remarkably thickened fore 
femora, and a fetor of its own.

TrinkomalI is very beautiful, and we saw it under the best of 
weather conditions, alike during an afternoon walk round Fort 
Frederick and an evening row in the lovely harbour ; but the whole 
place is wrapped in an air of gloom the impression of which has not 
yet worn off. 
Fort Frederick is entered by a fine gateway forming part of the 
old Dutch works; just inside will be seen the date 1676, but it was 
not captured by us till September 1795, and the Boyal Arms must 
have been set up later still. As I entered a native policeman saluted 
me; he and one other native seemed to make up the garrison. 
The fine ranges of barracks looked forlorn in the extreme ; a notice, 
“ this water to be used for washing only/’ seemed to grin mockingly 
at the visitor. In a singularly beautiful retired corner under the 
shade of a group of trees stood a row of tomb-stones marking the last 
resting-place of some of the Dutch officers of the quite old days. In 
an ancient battery close by were a couple of 32-pounders bearing 
the monogram “ G.B.” A 9-inch muzzle-loading rifle-gun, an obsolete 
weapon of the mid-Victorian epoch, set on end in the ground formed 
a seat. On every hand the remains of turn-tables and rotting
