340 BRITISH LEPIDOPTERA. 



without distinct segmentation ; the 3rd legs and apices of wings terminate together. 

 ? . Cylindrical, anus rather more pointed than head, abdominal segments 4-6 free ; 

 no waist ; abdominal segments 3-6 of almost equal size ; anus smooth, scars of pro- 

 legs distinct ; spiracles black and raised ; sexual organs well-defined ; anterior 

 dorsal spines on abdominal segments 4-8, posterior row on segments 4-6 sharp ; wing- 

 cases small, folded ventrally, but do not quite reach end of metathorax nor meet 

 ventrally ; antennas short and small ; legs short laterally, sloping outwards, the 

 3rd pair very short ; the labrum well marked ; jaws full and rounded ; labium and 

 maxilla together form a large 3-lobed lappet ; dorsal head-piece forms a narrow 

 strip along front of prothorax. 



Imago. — $ . All four wings strongly reticulated ; antennas 15 joints, pectina- 

 tions scaleless, no anterior tibial spur ; the scales specialised, very slender, still 

 clearly defined scales with a few striae on costa. ¥ . Vermiform, no ovipositor, but 

 ovipositing segments possess rods fairly developed ; does not carry pupal head-parts 

 after breaking case open ; has definite chttinous plates on dorsa of abdominal seg- 

 ments ; the thoracic segments delicate, without dark plates ; dark head-parts 

 include very modified mouth structures ; no antennas ; no wings. 

 Neueation. — Median forming a cellula intrusa in the cell. 



We have already named retiella as the type of the genus. There 

 are probably only two species yet described belonging to this genus, 

 W. retiella and W. undulella, the former at present only reported from 

 England and Holland, the latter from Hungary and southern Eussia. 

 They are both exceedingly pretty, undulella, although slightly larger, 

 being even more delicately marked, than retiella. They are true 

 Epichnopterygids, the delicate eggs, spindle-shaped case, unsealed 

 pectinations of male antenna?, absence of the anterior tibial spurs, 

 and vermiform female, all pointing to a close alliance with the "pulla " 

 group in spite of the very different looking $ imagines. It is remark- 

 able though that the peculiarity presented by the latter {Kpiclinop- 

 teryx) and by the Proutiids, viz., the female carrying the pupal head- 

 piece on emergence after using it as it were as a lever to break open 

 the puparium, is not found in Whittleia, where the 5 pup a itself 

 forces open the free end of the puparium before the female imago 

 emerges from the pupa (of course within the puparium).

Original description. — Mr. Ingall has captured a small Psyche 

 with beautifully mottled wings ; it is very different from the known 

 British species, but in some degree resembles Psyche undulella of the 

 continent. It is proposed to call the new species Psyche retiella 

 (Newman, Zoologist, v., p. 1863). [It will be seen from the above 

 that the insect was named retiella, not reticella, the latter name having 

 been adopted (Zoologist, viii., pp. xciv-xcv) by Newman in 1850, three 

 years later. He then diagnosed it as: "Psyche reticella, mas. — 

 Antenna? corporis dimidio vix longiores quasi 13-articulata? articulis 

 2-12 ramulos duobus ad apicen emittentibus, alis albidis fuliginoso
