of the wings, especially in the hind pair, and by the discoidal cell not having a line of dark scales running through 
the centre of it. The body is of a golden green, or tawny olive greenish colour ; the second and third segments 
of the abdomen nearly black, and the two following bright orange coloured ; fan-tail black, with the middle 
orange. The antennz are cyaneous, and the fore feet black. 
The caterpillar when about ten days old is covered with several branched spines on each segment of the 
abdomen, which are subsequently obliterated, the larva becoming smooth, but varying much in colour ; being 
sometimes green with a pale lateral stripe, adjoining which are a row of reddish crescents (sometimes wanting) 
extending to the tail ; there is also a row of oval spots placed obliquely, and extending round the spiracles. It is 
figured by Curtis. The caudal horn is described by Zetterstedt as straight, whereas in the preceding species he 
describes it as curved. The caterpillar feeds on the Devil’s-bit scabious (Scabiosa succisa), and some other plants. 
This species is of rarer occurrence than the preceding, frequenting the same situations, and especially delight- 
ing to hover over the flowers of Pedicularis palustris and P. sylvatica, from which it extracts the honey with 
its long spiral tongue. They have been found at Enborne in Berkshire ; Coombe Wood, Epping Forest, 
New Forest, and Huntingdonshire, are recorded as other localities. 
The confusion which has occurred respecting the identity of the former species, has been rendered doubly 
confounded, by Ochsenheimer and Stephens giving the former species under the name appropriated to the 
present insect. 
FAMILY II. 
ANTHROCERIDA, Westw. ZYGAINIDAS, Leacu. 
We have here a family of insects possessing characters as completely at variance with those of the preceding, 
as are to be met with amongst any of the remaiming groups of Lepidoptera. It is true indeed that the antennz 
are sometimes clavate and the flight diurnal, thus resembling the terminal Sphingide and the Trochilide, but this 
is all. Throughout the true Sphingide we find a peculiar form of the palpi, namely, a swollen second joint, and 
an almost obsolete terminal joint; in these insects, however, it is the basal joint which is enlarged, whilst the

third is almost or quite as long as the preceding. The veins of the wings again, throughout all the preceding 
insects, offer the same arrangement as shown in our figure of Smerinthus Populi; in the Anthroceridz, however,
