AND THEIR TRANSFORMATIONS. 07 



of the wings, especially in the hind j.air, and hy tlio 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. Tlie antenna) 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 wantin") 

 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 .'^ame 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 Enborno in Berkshire ; Coonibc 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. 

 ANTIIROCERID.E, Westw. ZYG.EN1D/E, Leach. 



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 remaining groups of Lcpidoptcra. It is true indeed that the antenna; 

 are sometimes clavate and the flight diurnal, thus resembling the terminal Sphingidiu and the Trochiliida, but this 

 is all. Throughout the true Sphingidie 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 tlie 

 third is almost or quite as long as the preceding. The veins of the wings again, throughout all the preceding 

 insects, ofier the same arrangement as shown in our figure of Smerinthus Populi ; in the AnthroeeridcB, however, 

 they are quite difterently arranged, and far more numerous and complicated (as figured in my Introd. to Mod. 

 Classif. V. 2, p. 372). The head is generally furnished with a pair of ocelli behind ; the antenna; are never ter- 

 minated by a pencil of hairs ; the spiral tongue and legs are long ; the posterior tibia; furnished with four spurs ; 

 and the extremity of the body is not terminated by a fan-tail. 



These insects are of comparatively small size, and are distinguished by their brilliancy of colour ; in their 

 flight, however, as well as in their larva state, they are slow in their movements, the latter being of a cylindrical 

 form, generally clothed with short hairs, without any spine at the hind part of the body, considerably resembling
