3. Suffolciensis, sp. n. 



Head clothed with grey hairs, biiccate and not narrowed beliind the 

 eyes ; black, with apical half of the mandibles red and palpi piceous ; 

 frons shining, finely and somewhat sparsely punctate, obsoletely canalicu- 

 late centrally ; face dull, strongly and coniluently punctate, with the 

 epistoma prominent ; clypeus transversely rugose, narrow, deeply discreted, 

 apically reflexed and simple ; cheeks finely punctate and very short. 

 Antennae black ; of ? filiform, hardly longer than half the body, and 

 sub-incrassate before the obtuse apices, with the ten basal joints red ; of 

 $ sub-setaceous, immaculate and two-thirds the length of the body. 

 Thorax black and shining, with grey pubescence ; mesonotum finely 

 punctate, with the disc coarsely and longitudinally punctate, and notauli 

 distinct, though short ; metathorax with complete areae and small, though 

 acute, apophyses ; areola nearly circular, not broader than long, with the 

 apical margin truncate ; petiolar area flat, finely coriaceous, shining and 

 not discreted ; spiracles oval and not small. Scutellum black, glabrous, 

 with a few scattered punctures ; its basal fovea apically margined and 

 centrally bisected. Abdomen glabrous and nitidulous, with grey pubes- 

 cence ; of ? ovate and clear red, its basal segment, except at apex, black, 

 glabrous, sub-bicarinate to beyond its centre and margined throughout ; 

 of $ elongate, black with most though never whole of second and third 

 segments red, fourth often discally red, sometimes only the incisures of 

 the second and third segments red, its basal segment slender, elongate 

 parallel-sided, aciculate between the somewhat prominent spiracles and 

 apically glabrous ; terebra shorter than the basal segment. Legs stout 

 and black; all the tibiae except apices of hind ones in <?, and tarsi 

 except anterior in 9 , and anterior femora except at base, red ; coxae 

 and trochanters of $ more or less piceous ; tibiae stout and externally 

 spinulose. Wings a little clouded ; tegulae and stigma piceous. Length, 

 4-6 mm. 



The much smaller size, very finely punctate frons, sub-circular areola 

 and infuscate male abdomen will at once distinguish this species from the 

 preceding ; and from G. clypealis it may be known by the coloration of 

 the clypeus, palpi, coxae, etc. 



This species is so abundant, at all events in Suffolk, that I can only 

 account for its having been hitherto overlooked by referring to the general 

 muddle into which the group to which it belongs had fallen. Both sexes 

 are taken freely in company, though never in cop., upon the flowers of 

 Heracleutn sp/iondy/iutn, Cliaerophyllum sylveslre and Spirea u/maria, from 

 the middle of June to that of July. I first met with it at Moulton, in 

 Suffolk, on 17th June, 1899, where thirteen males and twenty-one females 

 were captured upon the first-named plant ; thence until 14th July both 

 sexes occurred freely at Monks' Soham, I'ramford, \\'herslead, Henley, 

 Marlesffjrd, Farnham and Henstead, in the same county, where the female 

 outstays the male ten days. Elsewhere I have only received females from 

 (lolspie, in Scotland, in July, from Colonel \'erbury ; Askern, in \'orks., 

 from Mr. Roebuck ; and from Dundonald, in liilv, from Mr. A. .\. 

 Dalglish.
