uncertain concerning his synononiy, since the areolct was either absent or 

 entire. 



It has hitherto been known only from Smiiland in Sweden. I captured 

 a female, along with Omorga Fauuiis, on fennel flower at Ringstead village 

 in Norfolk on 21st August, iqo6, a second also on fennel flower at Alder- 

 ton in Suffolk on 3rd September, 1899, and swept another at Henstead 

 marshes near Lowestoft early in July, 1906; the male has only occurred 

 to me at Southwold in early September. The c\'linilrical body is remark- 

 able.

Black with the body small and very slender, and abdomen fasciated 

 with red. Head with vertex broad, cheeks not buccate, mouth small and 

 9 face narrow; palpi and mandibles stramineous. Antennal flagellum 

 very slender and nearly as long as body; scape flavidous beneath. Thorax 

 elongate and immaculate, with areola long. Abdomen linear and narrow- 

 er than thorax, black with apices of the second to fourth segments and 

 most of the fifth testaceous-red ; postpetiole subquadrate, a little broader 

 than petiole ; second segment elongate with large thyridii ; anus com- 

 pressed and the reflexed terebra very slightly exserted. Legs rufescent- 

 testaceous, with hind coxae black and the anterior, as well as both joints 

 of trochanters, whitish ; hind tibiae hardly infuscate at apex and before 

 base. Areolet sub sessile or nearly pentagonal. Length, 4-5 mm. 



This and the next species are divided from all the rest of the genus by 

 Thomson as alone possessing : — The capital vertex broad though roundly 

 constricted behind the eyes, the 9 f^it^"*-' narrow, cheeks not buccate and 

 mouth small; the areolet nearlv sessile or subpentagonal ; the abdomen 

 linear and fasciated with red, its second segment elongate with large 

 thyridii and the terebra hardly exserted; the bodv small and \('rv slender, 

 with the flagellum very thin ami ni'arly as long as tin- body. I'lie presi'iit 

 species cannot be Jh/oboiis ii/fiiiians (Brisch. 18.S0, p. 174, V), for that 

 has the nervellus geniculate. 



It is said to be rare in northern and central Europe, and I much doubt 

 its being truly British, (jravenhorst knew a single Silesian female; it has 

 been found by Thomson at Ortofta near Lund and by Dr. Lethierry in 

 France. It was, probably erroneously, introduced as British in Marshall's 

 1870 Catalogus, and has not since been mentioned — except in the un- 

 reliable Devon catalogue by Barfitt, who slates it to have been " taken on 

 the heads of UmbellifiTae in June." I have seen nothing like it.
