2S4 [May, 



one and a-half times as long as broad, and is five or six times as 

 long as the very sliglitly narrower second joint ; beneath these 

 joints isa large blackish blotch running across diagonally near 

 the base of the first joint, and about the tip of this joint are some 

 dark spots ; the other three joints are dull blackish and simple. 

 The middle legs have the knees dull yello-n^sh, the tibiae slightly 

 curved, and the two basal joints of the tarsi clear luteous, the 

 pubescence behind the femora is much less than that on the front 

 pair, and the tibiae bear outside, about the middle, a slight fringe 

 of longish hairs ; the hind tibiae are slightly bent before the tip, 

 and the basal joint of the hind tarsi is considerably dilated and 

 lengthened. The wings have a greyish tinge, the stigma is 

 brownish. 



The female is smaller and blackei', the abdominal spots being 

 more indistinct, the frons extra broad, the abdomen more shining, 

 the knees more distinctly yellowish, the front tarsi all brownish 

 and simple, the basal joints of the hind tarsi large and long, but 

 not at all conspicuously dilated. 



I am thus exact in describing this species, as my insects 

 differ from Wahlberg's and Zetterstedt's description, sufficiently 

 to raise doubts as to their identity. "Wahlberg, in his original 

 description (Ofv. k. vet.-akad. Forh. i, 6G), says " abdomine — 

 "maculis flavidis — geuiculis anterioribus latins posticis anguste 

 " testaceis ; metatarsis posticis 2)(tntm incrassatis — Mas, maculis 

 " abdominis obtuse sub-trigonis ; tibiis anticis simplicibus ; meta- 

 " tarsis anticis modice ohliq^iie dilntatis, latitudine duplo longi- 

 " oribus, cum articulo secundo qiiadrato, dilatato, albidis ; femoribus 

 " anterioribus lateri posteriori, posticis anteriori, longius ciliatis. 

 " Femina — metatarsis f usco-testaceis — Mas, pedes iiitermedii arti- 

 " culis tarsorum 2 primis hasi apiceque angustissime testaceis. 

 " Femina, pedes anteriores femoribus hasi angustissime apice fere 

 "ad dimidium, tibiis basi ad dimidium et apice angustissime 

 " testaceis.'' Zetterstedt further says " Mas — pedes antici, tibiis 

 " albidis pone medium late nigricantibus, tarsormn articulis Imo 

 " oblique, 2doque sub-qitadrafim, dilatatis. Fern. — abdomen multo 

 ^^latius quam in ^, maculis sex transversis, elongatis, fascias 

 "3rectas interruptas, albo-flavidas constituentibus." Where I 

 have italicized in these quotations, the descriptions differ con- 

 siderably from my species, yet in opposition to this, I place the 

 strong probability of the same species occurring in considerable 

 numbers (as it does) in North Europe and Scotland.
