by Miss Chawner, in Jul}' by Adams; from Colintraive near Glasgow on 

 24th I\Iay, igoo, by lialglisli; T,yme Regis on 22nd April and Kilmore 

 on lylh August (Beaumont) in Irt-land, where Col. Yerbury took the 

 female at Caragh Lake on 13th August, 1901, referred to by me (E.M.M. 

 1902. p. 55), 'i'he only Suffolk example is a female, which Elliott cap-

A nitidulous black species with no red abdominal marking, the calcaria 

 curved and not elongate, and the hind tarsi flavescent. Head with the 

 cheeks very short ; mandibles rufescent flavous and face densely white- 

 pubescent. Antennae with the joints discreted and the ^ scape flavidous 

 beneath. Abdomen immaculate black; petiole small with superficial 

 lateral foveae and postpetiole broad; ventral plica basally flavous. Legs 

 fiavidous with the coxae, trochanters and hind femora black; anterior 

 coxae and trochanters of (J pale; hind tibiae stramineous with their base 

 narrowly and apex broadly nigrescent; outer calcar short and curved. 

 Wings with stigma flavous and nervures nigrescent; discoidal cell dis- 

 tinctly a little acute externally below. Length, ii-i4mm. 



One of the most conspicuous of the genus in its shining, subglabrous 

 and entirely black abdomen with the petiolar glymmae .small and not 

 deep, the broad postpetiole and basally pale ventral plica, in the coloura- 

 tion of its hind legs and their curved calcaria. Holmgren's name has 

 not before been synonymised with that of Desvignes, but an examination 

 of the latter's typical male in the National Collection, which was "reared 

 from Anajia jSlyrtilli^' at once revealed their identity. 



The two females, originally described from Sweden, were captured by 

 Thomson. 1 have seen a single male of this species,* sent for determin- 



* No adequate description of the i is extant. The following was drawn from Bradley's specimen 

 in 1900: — 



Head black ; occiput and frons exceedingly finely scabrous and nude, latter somewhat excavated 

 above antennae ; with rather dense grey pubescence behind the eyes ; eyes distinctly emarginate 

 level with the antennae; face convex, closely and coarsely punctured and quite hidden by very long 

 grey, silky, deflexed pubescence ; clypeus a little raised, truncate and inmiarginate at the apex ; 

 mandibles broad, acutely but shortly bitid at the apex, entirely flavous excepting the teeth which 

 are infuscate, the inner hardly longer than the outer, (mandibles) with scattered punctures and 

 pilosity, nitidulous ; maxillary palpi flavous, paler towards the apex, pilose quadri-articulate, first 

 joint somewhat incrassate ; labial palpi flavous, pilose, three-jointed ; second joint nodose apically. 

 Antennae lonim. in length, of uniform thickness, entirely black, scape scabrous and pilose, i'horax 

 black; dorsum of metathorax finely scabrous-punctate, tinely bordered throughout from prothorax 

 to scutellum; mesoplcurae finely, distinctly, but not very regularly punctured and somewhat uneven, 

 not divided from mesosternum by a ridge ; mesosterna rather more regularly and a little more finely 

 punctured, slightly depressed and transversely bordered posteriorly, their interpectoral sulcus trans- 

 striate and not widened behind ; metathorax scabrous with areae somewhat indefinitely demarkated 

 in the centre. The areola is confluent with the petiolar area which is strongly transversely scabrous 

 and feebly longitudinally cannate at its apex; superoexternae are divided from dentiparae, which 

 bear no teeth, by an extremely indefinite line ; postero-intermediae and externae are subobsolete ; 

 spiraculiferae and pleurales strongly marked ; tlie spiracles ara large and elongate-oval. Scutellum 

 and post-scutellum black, somewhat elevated, rugose, immarginate, with erect, not very dense, grey 

 pubescence. Abdomen, except the obsoletely ferrugineous apices of the two basal segments, entirely 

 black, extremely finely punctured and haired, pilosity becoming thicker towards the apex ; first 

 segment with inconspicuous spiracles at its apical third, just beyond which it is somewhat pro- 

 tuberent dorsally, and transversely slightly depressed at its apex ; second segment slightly depressed 

 at the base and apical third ; third glabrous at the apex ; eight segments exserted ; apically truncate : 

 with central fold on four basal segments below, of which 2—3 are bright sattron-yellow. Legs bright 

 yellow ; front coxae at the base, intermediate above, and the whole of hind coxae and femora black ; 

 posterior trochanters and base and apex of tibiae inluscate; all coxae, trochanters and femora finely 

 punctured; all tibiae finely externally setose. Wings hyaline; areolet large triangular-quadrate; 

 stigma ferrugineous; costa and nervures piceous with former, as well as radix, fulvous; tegulae 

 flavous. Length, 1 1^ mm.
