494 Mr. W. A. Lamborn on the 
larva of Aslauga lamborni. I have since found that the 
little moth larvae eat out the inside of the Coccids, attacking 
them from underneath, and when one is eaten they con- 
struct a tunnel so as lead to and get beneath another.” 
It is probable that the minute Lepidopterous larva 
which Prof. R. Newstead describes as preying upon S. 
sjéstedti is allied to T. callopista (see p. 522, also Journ. 
Kcon. Biol., vol. v, 1910, p. 22). 
D.—ANTS AND MEMBRACIDAE. 
The following section deals with the relationship between 
ants and Membracidae and incidentally includes observa- 
tions on the life-history of one species,—L. altifrons. This 
section should be read in connexion with that upon Megalo- 
palpus zymna (p. 458) and especially pp. 463-468, where 
many other observations on Membracidae and their attend- 
ant ants are recorded.

No. 38. “ These insects are fairly plentiful on the growing 
stem of the food-plant of Acraea bonasia, F.— Triumfetta 
cordifolia, Guill. and Perr., var. holland, Sprague (Tiliaceae), 
and I see them occasionally on that of A. parrhasia, F. 
—Urera obovata, Benth. (Urticaceae). They are invariably 
attended by ants. Sometimes they are found singly and 
sometimes there are several together. They are easily 
examined in situ, but hard to catch, as they jump off to 
an astonishing distance and take to flight with great 
suddenness.” 
The 14 specimens bearing. No. 38 were found Oct. 14, 
1911, in the forest 14 miles E. Accompanying them is an 
ege-mass on Urera obovata, with the same data. 
Companies of mature forms are frequently found, but 
never as far as I remember on green stems, and I am dis- 
posed to think that these massed individuals are invariably 
such as have only just emerged from the nymph condition 
and that they scatter when hardened up. (See also Proc. 
Ent. Soc. 1913, pp. xxxvi—xxxvii, and xxxvii footnote.) 
One frequently finds mature forms feeding on green stems 
but rarely more than two together, and they are invariably 
ant-attended. Thus among the specimens sent is a single 
large L. altifrons, found Jan. 14, 1912, on a green stem in
