A NEW PHALACKOPTEKYGID SPECIES AND OENUS FROM SPAIN. 325 



tunate that Staudinger uses PhalacropteriT in quite a different sense 

 for a Psychid (tribal sense) genus, including apiforinis.] 



If, therefore, Oreopaiiclw (Staudinger) is to be divided into three 

 genera (Tutt), it is tolerably certain that iiwHcaunella is the type of a 

 new genus, on the ground of the very exceptional form of the wings. 

 I propose for it the new genus Pyropsyche, which may be described 

 as follows : — 



Pyropsyche, n.g. — A Phalacropterygid (Oieopsychid) genus in which the fore- 

 wings are very elongated and pointed, markedly differing from every other genus 

 in the group. In the type species the forewings have eight veins from cell, vein Ih of 

 the hindwing is always (so far as observed) branched, and the colour is largely 

 brilliant orange. Type moncaiuiella, n.sp. 



The description of the species is as follows : — 



cJ . Expanse 22mm., length of forewings lOram., of hindvvings 7mm. 

 {Phalacropterix muscella, for comparison, has forewings 8'5mm., hindwings 

 Tmm.). Hind margin very slopmg, and forewing pointed, as compared with 

 any other Oreopsychid I know. Neuration of forewing, eight veins from cell, 

 branching of lb, l-4mm. from base ; of hindwing, five veins, as in Phala- 

 cropterygids, la nearly obsolete, Ic very weak, lb strong, and divides before 

 half its length into two branches. This seems to be so in all specimens. 

 An inner branch from lb occurs sometimes in P. muscella, but is unusual. 

 Antennae (5mm. long, longest plumules 2mm., scales to tips, 32 to 34 plumules 

 on either side (in P. muacella, 25 to 27). The insect is clothed with long 

 hairs, about l-.5mm. long, on head, 3-5mm. on last abdominal segment, 

 and graduating between these. The hairs on the wings look like an extension 

 of the body-hairs rather than wing-scaling, and are especially long and thick along 

 the inner margin of the hnidwing. The tarsi are without hairs, but the tibiae 

 are clothed with hairs as long as themselves — the anterior sparsely, the posterior 

 almost densely. The hair-scales of the wings are much as in P. iniiscella, but a little 

 less dense. The colouring gives its especial aspect to the species. The antennae 

 are black, as well as all chitinous parts of the body. On the head the hairs are 

 sometimes entirely orange-yellow ; in the type specimen black hairs predominate 

 laterally. On the thorax the hairs are orange above, black below. On the 

 abdomen the hairs are orange-yellow basally, gettmg redder, till, on 6th segment, 

 they are red rather than oi'ange, and have some black hairs ventrally . The long hairs 

 of 7th segment are entirely black, and contrast sharply with those of 6th. On the 

 legs the long hairs are black, but the scaling of the tibiae and tarsi is orange, and the 

 chitin of undersurface and of last joint of tarsi is also orange, so that the legs 

 become more brightly coloured towards their extremities. The wing-bases are 

 entirely orange, long hairs, hair-scales, and nervures, and the long orange hairs 

 of inner margins reinforce the mass of abdominal colour. The hair-scales darken 

 outwardly so as to be black by the middle of the wing. The nervures also get 

 darker as they proceed, more by being narrower and more obscured by hair-scales, 

 than by essential change of colour or texture. Still the rough effect is that they 

 are bright orange basally, nearly black towards the cilia. The cilia are long and 

 thick, and are black, except at base of inner margin of forewing and at anal angle 

 and inner margin of hindwing, where they adopt the bright orange coloration. 

 [A close examination of P. iiuiscella shows a tendency to yellowish coloration of the 

 hair-scales on the cell of forewings, everything else except the pale tarsi being 

 black.] ? . The female is about 10mm. long. The ovipositor, when extended, 

 seems not to reach beyond the general rotund outline. The spiracles are well- 

 marked, and the two main trachea are very large, tolerably straight tubes, reaching 

 from end to end of the insect. Anteriorly there is a brown chitinous shield, which 

 may be called the cephalothorax, it covers the anterior end, and the dorsum and 

 two sides adjoining. On each side is a lappet, something like a bloodhound's ear. 

 If the insect were distended instead of flaccid, this would probably have a different 

 aspect. The lappets are the sides of the headpiece slipping back over the sides of 

 the thoracic piece ; dorsally, however, the head and thoracic pieces are continuous, 

 without indication of joint or suture. The 1st spiracle is in the angle under the 

 edge of the lappet, the thoracic piece is laterally one, but by a faint line, and by 

 its relation to the 1st and 2nd spiracles, it would appear to consist of the dorsal 

 plates of the 1st and 2nd thoracic segments. There are two circles in each of which a
