Aleurodidae. 
Peal describes the function of the vasiform orifice of the 
Aleurodidae (J.A.S.B., |. XXII [II], pp. 6-7). 
Coccidae. 
Imms records the occurrence of Dactylopius citvt in ants’ nests 
(Rec. Ind. Mus., VI, p. 111). 
MYRIAPODA. 
The habits of a number of Malay Myriapods are described by 
Flower (/. Straits R. Asiatic Soc. No. 36, 1901, pp. I-25). 
Concerning the food of Scolopendridae see Wells-Cole, Okeden 
amdnCummmine (J J>.N o.oo. “ll, ps2t4 and XV. pp. £35, 1 pl., 
and 364-5 respectively). 
Mr. G. Mackrell tells me that Fthmostigmus pygomegas is com- 
mon on his tea garden in Sylhet just below the surface of the 
ground. Specimens are sometimes found in earth round the roots 
of grass growing at the bottom of a bush; but they more often 
crawl into light soil leaving no visible hole, or in between clods of 
earth. In captivity they appear to be nocturnal, and to shun light. 
Their food consists chiefly of worms and small insects, and they 
seem to be fond of Acridiids and Gryllids. 
I have already described the stridulation, apparently to 
attract attention away from the creature that had cast it, ofa 
detached leg of Scutigera decipiens (J.A.S.B.[n.s.], [X,*pp. 415-6). 
More recently I noticed a detached leg of a Cochin species moving 
in the same manner, and on holding it to my ear was able to hear 
it squeaking. In this case, however, the squeak was much 
fainter, and was produced by legs which remained 7” situ as well 
as by others. 
The occurrence of purplish-red millipedes in herds is noticed by 
Cunningham (‘‘ Plagues and Pleasures’’, p. 193). I have some- 
times seen such herds on the muddy banks of the Havildars’ 
Tanks on the Calcutta maidan, especially, if I remember rightly, 
in the spring. 
Some of the larger species of Indian millipede exude an evil 
smelling coloured fluid when disturbed. The common big black 
species in the Cochin Ghats does this, but nevertheless falls an 
easy prey to its enemy the Reduviid bug Physorhynchus. A still 
larger black species, in which the middle of each segment is 
girdled with extra thick chitin, and the caudal horn is excep- 
tionally long, emits a particularly virulent fluid which not only 
smells, but also stains and burns one’s hands. This species was 
only found near the head of a small valley at Kavalai (Cochin 
Ghats) where, however, it was much commoner than the common 
form of the district. I regret that I did not also try Physorhyn- 
chus with it.
