Although sanguinana, Tr. (which is not a Lozopera), is wrongly 

 included in this group, von Heyden's conjecture is amply justified in 

 the possibility o£ critically distinguishing several species hitherto 

 confused, although their larval habits, so far as we know them, are 

 extremely similar, as might well be expected in a natural and well- 

 defined genus. 



I have purposely omitted in the following descriptions any refer- 

 ence to the form of the genital armature, which it would be exceedingly 

 diflB.cult to express in words. The accompanying accurate illustrations 

 by Mr. Hartley Durrant will enable a comparison to be made, and will 

 amply justify the separation of the species on structural grounds — 

 several specimens of each having been carefully examined and found 

 to be alike. Will some specialist in comparative anatomy kindly 

 supply the connect terminology of this philogenetic puzzle ? 



LOZOPEEA FRANCILLONANA, F. 

 (PI. II, fig. 1). 

 Antennce pale primrose above, greyish beneath. Palpi very pale primrose, shaded 

 with pale chestnut externally. Head and thorax pale primrose. Fore-wings pale 

 primrose, with a pale chestnut shade along the base of the costaand two very oblique 

 transverse fasciae varying from pale chestnut to nut-brown, with a few silvery scales 

 around their margins ; the upper end of the first fascia, which commences on the 

 middle of the costa, is somewhat quadrangular, the fascia varying in width reaches 

 the dorsum at one-third, without noticeable excrescences, but expanding somewhat in 

 width to the margin ; the second fascia arising from the dorsum at about two-thirds 

 sends out a noticeable bulge immediately above the fold (this excrescence is not, 

 however, diffused towards the torn us), thence the fascia reaches the costa before the 

 apex in an unbroken band of about equal width throughout, although slightly en- 

 larged at the costa ; cilia whitish-primrose. Under-side greyish-brown, cilia slightly 

 paler than above. Exp. al., 14 — 18 mm. Hind-ivings greyish-brown, with a slight 

 tawny tint ; cilia whitish, with a faint tawny shade along their base. Under-side 

 pale tawny-grey. Abdomen greyish-brown ; anal tuft paler. Legs whitish-cinereous. 



JIah. : England. France, Cannes. Larva in stems of Daucus 

 carota and Ferula communis (Wlsm.). 



Type, Coll. Francillon (? in Oxford Mus.). 



Varieties occur in which the fasciae are more or less interrupted 

 below the costa, and some care is required to avoid confusing such 

 varieties with the Eryngimn-ieeAev fiagellana, Dp., which can be sepa- 

 rated by the more curved dorsal half of the first fascia, being 

 invariably separated from the costal spot above it. The species was 

 described by Fabricius from British specimens, but I am unable to 

 separate the common South European form occurring in stems of
