very much like the broken remnants of dead twigs jutting out from 
the bouch, especially as they nearly always sit with the snout 
pointing away from the trunk, and often remain absolutely still for 
hours and sometimes even days together. Moreover Mango and 
Longan trees are very twiggy, especially the former, and are 
crowded with little broken stems. In fact, though the insects are 
very common here wherever their special trees are found, yet it is 
but rarely that one discovers a nymph in the open. 
It may be added that the male is on an average smaller than 
the female, and that the sexes are about equal in numbers. 
Judeing from the effect on the plant produced by a number of 
nymphs as well as adults, feeding on small plants and trees, I think 
that there can be little if any harm done by Pyrops to large or 
moderate-sized trees, that is by the actual amount of sap they 
abstract. Whether their sucking induces fungus or other parasitic 
disease, [I am not able to say. ')

Anatomical Notes. 
The head of Pyrops, like that of most Homoptera, is greatly 
deflexed and inflexed; the epieranium is produced into a long snout- 
like process which projeets forwards and slightly upwards; the 
labrum, with other parts of the head, forms a “beak” through the 
1) Among other matters which may be alluded toxin connection with 
Pyrops are the following. ' 
For observations on the use of the snout, cf. notes by FLETCHER (6) 
and especially by ANNANDALE (1). 
Another fable conneeted with the large Fulgoridae was that they 
“sang” during the night-time. Fulgora laternaria was stated by STEDMAN 
(21) to be called “scare-sleep” by the Dutch in Guiana, but this was 
correctted by Hancock (9) who nevertheless said that the Fulgoras 
sang rarely. The real offender is a Cicadid [cf. Kırgy & SPpEncE (10)]. 
Although some species of Derbidae and Asiracidae stridulate |cf. KIRKALDY 
(11)], tbe Lantern-fiies do not do so, as is correctly asserted by CHAM- 
PION (3). 
In China, there is, or was, an edict issued against girls keeping 
“Janthorn-flies’”’, but I know neither the reason nor the details [cf. WEST- 
wooD (22)].
