Peleteria. 429 



beset witli long, recurved hairs, the apex pointed and bare; arms 

 of lower forceps of an equilateral triangular shape, and looking as 

 forming part of the side of hypopygium, the posterior margin is folded 

 inwards and ends in a spine-like apex; the outer surface has long 

 hairs. Legs red, femora black with apex red to a smaller or larger ex- 

 tent ; the legs are less bristly tlian in grossa. Wings yellowish at base, 

 and veins here yellow, brown ontwards. Squamulæ whitish with pale 

 yellow margin. Halteres yellow. 



Female. Similar; frons broader; third antennal joint generally 

 more square. Abdominal sternites with strong bristles. Femora quite 

 red or only black at base, rarely more black. 



Length 9 — 14 mm. 



Remarks: This species is known to vary to some degree as 

 regards coloiir, and it has therefore been described under several 

 names, but with us it seems to vary only a little. Most of our spec- 

 imens have only one median bristle on each side of second and third 

 abdominal segment. — E. tetramera Zett., the type of which, a female, 

 is in our collection, is nothing but a peculiar aberrant individual of, 

 I think, the present species (or possibly of magnicornis Zett.), with 

 only foLir joints on all tarsi. It is, however, a rather puzzling specimen, 

 but manifests its abnormity by not only the front but also the middle 

 tarsi having the intermediate joints dilated, and the second joint 

 on the right hind tarsus is incised in the middle on posterior side and 

 nearly divided. 



E. jera is less common in Denmark than grossa; Tisvilde, Rørvig 

 (I. C. Nielsen, the author), and in Jutland at Silkeborg and Funder 

 (Esben-Petersen); the dates are ^"/e—^'/e- O- F- Mijller enumerates 

 it in Faun. Fridrichsd., but the citation is rather doubtful and may 

 well belong to a Peleteria. It is known parasitic on Ly mantria dispar 

 and monacha, Mamestra pisi, Agrotis glareosa, Leucania obsoleta, 

 Panolis griseovariegata, Arctia aiilica and Oeonistis qiiadra. 



Geographical distribution: — Europe and down into North 

 Africa; towards the north to middle Sweden.

 shows several distinguishing characters. Head mainly as in Echino-
