A NEW PHALACROPTKRYGID SPECIES FROM SPAIN. 67 



(Insert Lifr, 1890. pp. 236-287, tig. 47), the form of the species 

 occurring in Minnesota, in North America, has the forewings rusty- 

 black, the hindwings of a similar colour but much lighter, and with a 

 brick-red, ill-defined space at the posterior margin ; the fringes of both 

 fore- and hindwings pale red. Judged by the descriptions the eastern 

 (Asiatic and American) races are less ruddy than the western. 

 Lugger's figure appears to have the markings distributed as in our 

 intermedia form. Doubtless, in America, there is as much tendency to 

 form local races as in Europe. 



A new Phalacropterygid species and genus from Spain — 

 Pyropsyche moncaunella {u-ith plate). 



By T. A. CHAPMAN, M.D., i^\Z.S., F.E.S. 



{Concluded from Vol. xv., p. 330.) 



The Plate (in illustration of this species, vol. xv, pp. 324-330) 

 having been delayed in production, the following explanation now 

 appears with it. 



Explanation of Plate. 



Fig. 1. — Imago J , Pyropsyche moncaunella, rather over twice natural 

 size, the large specimen figured is 22'5mm. in expanse. 



Fig. 2. — Neuration of forewing of P. moncaunella from camera 

 drawing. 



Fig. 3. — Neuration of hindwing of P. moncaunella from camera 

 drawing. 



Figs, 4 and 5. — Neuration of forewings of P. moncau)u'lla from 

 camera drawings, from two specimens in which a 

 missing vein is partially represented ; Fig. 4 would 

 indicate that the missing vein is vein 5. 



Fig. 6. — A similar example from hindwing, the re-appearing vein is 

 probably vein 3. 



Fig. 7. — Forewing of Phalacropteri.r inuscella for comparison, there 

 is practically no portion of lb between its union with la 

 and its bifurcation, this is, however, represented in 

 some specimens [la arising from lb, as shown in figure, 

 is a slip in copying). 



Fig. 8. — Hindwing of a variation of neuration in P. muscella. lb is 

 usually simple ; in this specimen it branches not only as 

 in P. )iu))icaunella, but a second time. On the other side 

 of the same specimen it branches much as in moncaunella. 

 These variations found in a few specimens illustrate 

 the plasticity of the neuration in Psychids. [The 

 wing form in P. anyustella (which is hardly congeneric 

 with — atra, 'ii&y\.=plumit'era, Ochs.) is nearest to P. 

 moncaunella of any Oreopsychid, but the neuration is 

 less close than that of P. muscella. It would possibly 

 result from the plasticity referred to that a sufficiency 

 of specimens would bridge over the differences.]
