Dactylopius longispinus, Targioni-Tozzetti. 
A common and widely distributed pest. Fernald * and 
many other students now refer Dactylopius, Targ.-Tozz., 
to the genus Pseudococcus, Westwood. I have thought 
best to retain the name which has been so long in use, so 
as to avoid confusion in this communication.

Dactylopius virgatus, var. madagascariensis, Newst. 
The specimens are all in very bad condition and are 
denuded of their characteristic covering; but there can, 
I think, be little doubt as to the correct identity of the 
species as all the morphological characters agree with 
typical examples of this Coccid. This insect seems to 
have established itself in other parts of Western Africa, 
as I have recently received examples from Ilorin, Northern 
Nigeria, also on “Pride of Barbados,” Caesalpinia 
pulcherrima, Sw.

Lecanium puncetuliferum, var. lamborni, n. var. 
Female, adult, ovate, moderately convex, margin broadly flattened 
though in some individuals it is slightly reflexed; integument 
apparently strongly rugose at the margins; but is so thickly coated 
with dirt, that the true texture is practically obliterated. Colour 
(dead examples) pale brownish-ochraceous, dusky greenish-yellow, 
reddish-brown or chocolate-brown. Antennae of seven segments of 
which the third and seventh are the longest. Legs well developed ; 
tarsus exclusive of the claw nearly as long as the tibia. Scales of 
anal operculum rounded distally; base much longer than’ distal 
margin. Derm cells small, oval, widely separated and visible only 
towards the margin. Stigmatic cleft extremely shallow; spines 
three, the median one of great length. Marginal spines long 
fimbriated distally; short simple spines occur between the larger 
ones, sometimes alternately. 
The young females are much paler than the adults—varving 
between yellowish-buff and reddish-buff; two examples also 
exhibit traces of lateral black markings, and in one of them these 
coalesce posteriorly and form an interrupted U-shaped line. The 
anal operculum in the young females is markedly attenuated and 
very narrow. The antennae are similar to those of the adults, but 
in one example these organs are asymmetrical, the right antenna
