Legs black. Wings hyaline orslightly tinged, more at base; squamular pieceat base of costa black; subcostal sclerite without bristles. Squamulsewhitish, the lower more or less brownish fumigated. Halters blackishor brownish. Female. Similar; frons about as broad as the eye. Squamulæ-whitish. Length 5,5 to fully 8 mm. L. silvarum is not specially common in Denmark; Lersø, Ordrup,Geel Skov, Birkerød, Hillerød, at Sorø; on Lolland at Nysted and inJutland at Sønderborg, Made Skov, Skeide, Høruphav and Graa-sten; the dates are ^^/^—22^^ Geographical distribution: — All Europe; towards the north tomiddle Sweden, and in Finland; it is also recorded from North Fig. 25. L. silvarum,forceps in profile. 144 Tachinidae. Remarks: As known, illustris Meig. and splendida Meig. are(besides others) considered as synonyms, but it is impossible to saywhether they belong to this or the following species; splendida ismentioned by Zetterstedt as sent from Stæger, and the specimensunder this name in our collection (Stægers) are silvarum, so that?at all events splendida Zett. may be considered as a synonym. 2. L. bufonivora Mon. 1876. Moniez, Bull. Dep. Nord. Lille, VIII, 25 et 1878. IX. — Feuille des jeun. Nat. 5, 44, 2, Fig. 1. Male. This species is quite similar to silvarum. Head of thesame shape and colour. Thorax with only two postsutural acrostichals,very rarely with three. Abdomen as in silvarumwith a pair or more of marginal bristles on thirdsegment. Forceps not so long as in silvarum; the upperforceps of about the same shape, the branchestruncate at apex; arm
