the centre longitudinally and subcarinately elevated. Antennae slender 

 and filiform, not apically attenuate and nearly as long as the body. Thorax 

 immaculate ; mesonotum deplanate ; metathorax finely and alutaceously 

 punctate with the areola obsolete and the petiolar area weakly carinate at 

 its base. Scutellum black. Abdomen utterly black with not even the 

 incisures paler, oblong-ovate or subfusiform, somewhat nitidulous, finely 

 alutaceous ; basal segment somewhat broad, a little longer than the hind 

 coxae, hardly curved, centrally elevated, with the distinct discal carinae 

 not extending to its apex ; the following segments transverse and finely 

 alutaceous ; terebra straight and about as long as the body. Legs red 

 and somewhat slender with the hind femora nearly parallel-sided ; hind 

 tarsi alone nigrescent. Wings subhyaline ; stigma infuscate, radix and 

 tegulae stramineous ; areolet sessile and emitting the recurrent nervure 

 between its centre and apex ; nervellus intercepting a little below the 

 centre ; radial nervure straight. Length, 7 mm. 



This species differs from those of the Segmin/cr/or-growp in having the 

 abdomen utterly black, with no trace of paler markings at the incisures, 

 the vertex not posteriorly emarginate and the size rather larger. 



Only known from Sweden and Belgium, where it appears to be very 

 rare. Bridgman introduced it as British (Trans. Ent. Soc. 1886, p. 373) 

 on the strength of a specimen bred by Fletcher at Abbots Wood, in 

 Sussex, from the pupa of some Toririx; subsequently he tells us that Fletcher 

 also raised it from Craiiibus salineUiis and C. contaniinellus, probably in the 

 same county ; and Atmore from Retinia turmiana at Kings Lynn, in 

 Norfolk.

Black and somewhat dull. Head transverse, laterally rounded and 

 narrow behind the eyes ; face transverse and a little broader than the 

 frons; palpi and clypeus fulvous, mandibles centrally and marks at the 

 frontal orbits flavous, ^ with sides of face more or less broadly and the 

 cheeks concolorous. Antennae filiform and as long as the body ; scape 

 of J flavous-marked beneath. Thorax finely and densely punctate ; 

 pronotum, a callosity before the radix and triangular humeral marks, 

 flavous ; (J also with a line below radix, mesosternum and sometimes 

 metapleural spots concolorous ; metathorax longitudinally impressed, 

 petiolar area basally prominent. Scutellum black. Abdomen with the 

 extreme apices of the segments obscurely rufescent, usually paler in ^ ; 

 basal segment about half as long again as apically broad, very finely punc- 

 tate with the interstices finely and transversely aciculate, and a slight
