A black species with the sericeous and somewhat dull abdomen and 

 the legs entirely red, only the petiole and ^ anus being usually nar- 

 rt)wly nigrescent; terebra nearly half length of abdomen; anterior tro- 

 chanters usually flavous; seventh segment of 9 centrally incised. Length, 



At once known by the almost totally red abdomen, the always sub- 

 elongate poslpetiole, clear testaceous stigma, usually red underside of 

 the scape and not apically rugose metathorax with its slender costulae. 



This is a sufliciently common species throughout north and central 

 Pairope, though not recorded from France; it has been bred by Brischke 

 in Prussia from pupae ot Ortholaelia SparganuUa and he says the cocoon 

 is elongate cylindrical and tlavidous grey-brown. With us there are few 

 records, but though decidedly local it is abundant wherever it occurs, 

 especially in the virgin bog of the New Forest and the salt marshes of 

 the Suffolk coast, in both of which localities 1 have seen it without fail 

 for the last ten years. Bridgman found it at Eaton, Brundall and Heig- 

 ham in Norfolk during July and August, and 1 met with it at Hickling 

 there in June; it is first seen about the middle of June and then in the 

 male sex only, for I have seen no female before July, from which time 

 both sexes are met with up to i8th September, always in marshes and 

 usually upon reeds. I have fifty examples from Delamere Forest (Tom- 

 lin), Tostock and Finborough Park (Tuck), Kilmore in Ireland (Beau- 

 mont) and St. Kilda in June, 1905 (Waterston) ; it has occurred to me on 

 Clare Island and the adjacent mainland of Ireland ; at Salisbury and in 

 the New Forest at Denny Bog, Matley Bog and Setley; in Suffolk it 

 appears restricted to the banks of the Gipping at Ipswich where it has 

 been swept at dusk, Henslfad Marsh and the Southwold salt-marshes, 

 where it annually abounds with J/, crassicornis.

A black species with the abdomen centrally broadly, and the legs 

 entirely, red ; the areola and postpetiole ijuadrate ; terebra nearly half 

 length of abdomen. Length, 0-8 mm. 



Very like A/, r ufa'iu t ris Viwd much mi.xid with il on the Continent, but 

 with the metathorax apically somewhat strongly rugose, the costulae 

 stouter, both metanotal areola and the postpetiole not longer than broad, 

 and the stigma distinctly infuscate testaceous, the whole structure stouter 

 and the anus determinately black.
