posterior segments. Similar spines are clustered on the small anal 
lobes and on a corresponding tract on the preceding segment. 
Intermingled with the spines are many minute, obscurely trilocular 
pores, which occur (rather more abundantly) on the venter also. 
There are some larger circular pores near the posterior extremity 
of the venter. Length (under compression) 2°5 to 4mm. Breadth 
2 to 3 mm. 
The early adult insect (before the production of the ovisac) is 
enclosed in a more compact, felted covering, of a grayish ochreous 
colour, which may be observed—even in older examples—as a 
pointed cap at the anterior extremity of the ovisac. The freshly 
deposited eggs are of a pale yellow colour, but become reddish 
before hatching. The number of ova produced by a single female 
probably amounts to several thousands. 
On a large arboreal Tamarisk (Tamartx articulata). Y.ahore. 
Collected by Dr. N. Annandalein May. ‘‘ T. articulata is one of the 
chief shade-trees in Lahore. Mr. Sundar Lal Hora, M.Sc., Research 
Assistant, Z.S.1., found the Coccid upon it in abundance in Octo- 
ber, but I have failed to do so on several occasions in January.

The extraordinary masses of tangled ovisacs must be very 
conspicuous objects on the trees, but might easily be mistaken for 
collections of bird droppings, st.ch as may often be seen on branches 
beneath the roosting places of flocks of sparrows. The insects 
excrete a considerable amount of viscid fluid which soon assumes 
a brownish colour. 
Lt.-Col. Stephenson (of the Government College, Lahore), to 
whom I am indebted for some excellent photographs of the insect 
and for fresh living material, informs me that—in nature—the 
long ovisac is always attached at each end, forming a simple loop. 
The subsequent tangled condition may be the result of wind. 
Naiacoccus serpentinus var. minor, nov. 
Distinguishable from the type by its smaller size and by the 
greater number of dorsal spines and dermal pores (fig. 6f). The 
circular pores of the venter are particularly conspicuous and are 
densely crowded on the posterior segments (see fig. 6g). The 
average size of the insect ranges from 1°5 to 3 mm.; but little 
difference can be observed in the length of the ovisacs which have 
precisely the same appearance as those of typical serpentinus. 
The antennae (figs. 6a-d) are shorter, the number of joints 
varying from 5 to 7, being usually reduced by complete or partial 
fusion. In some examples only 5 complete joints can be distin- 
guished ; but the 6-jointed from (fig. 6b, c) is the most frequent.
