. Col. Yorbiirv, Dr. Sharp, Mr. C. G. Lamb, and Prof. J. W. Carr, 

 while Mr. II. W. Andrews has taken it in Ireland. 

 5 (4) Greyer species with thoracic side-stripes limited to a small patch in 

 front and a narrow streak behind the suture. Normally four pairs 

 of postsutural dorsocentrals . . 25. scrupulosa Zett. 



cJ . Frons about as wide as in maculosa, but the frontalia ratlier 

 narrower and orbits wider and very silvery. Vertex and a trian- 

 gular patch on occiput behind the ocellar triangle light greyish. 

 Thorax very distinctive by reason of the much reduced side-stripes ; 

 median stripe widening out (but not to dorsoceutral rows) behind 

 suture, then narrowing again to scutellum. Presutural acrostichala 

 not more than biserial. Four pairs of postsutural dorsocentrals. 

 Abdomen with much restricted dark patches on first segment, a pair 

 of small triangular patches on second segmen*^, and a pair of smaller 

 more transverse patches on third segment. ilypopygium grey. 

 Middle femora with about four long bristles beneath towards base; 

 middle tibiae usually with two small bristles behind. Hind femora 

 with the anteroventral bristles more numerous <and sometimes more 

 extended towards base, and with the posteroventral hairs on basal 

 half certainly longer, than in maculosa. Wings as in all species of 

 tliis group only faintly tinged with brown. Squamae whitish. 

 Halteres yellow. 



$. Frons wide. Vertex, as in the male, distinctly grej'. Thoracic 

 stripes (enpecially the side-stripes) somewhat variable. The best 

 distinguishing character lies in the comparatively small brown 

 abdominal spots which lie on the hind margin of second and third 

 segments, and the absence (or very faint indication) of spots on tha 

 first segment. The anteroventral bristles on hind femora are rarely 

 present on more than the apical half, and there are no conspicuous 

 posteroventral hairs> 



Length 4'5-5 mm. 



This species can be recorded with certainty from only seven 

 specimens, four taken by Col. Yerbury — 1 c^" , - $ $ at Porthcawl 

 (Glamorgan) on July 18th, 1906, and a 5 atP_)le (Glamorgan) on 

 August ioth,1908, and three by Mr. II. W. Andrews (2 cJ c?, 1 9 

 at Porthcawl, June 28th and 30th, 1913). The specimens upon 

 which Meade introduced the name to the British List were 

 (according to some notes made by Mr. Verrall on one of Meade's 

 specimens) only females of Limnophora humilis {septemnotuta Auct.), 

 I have examined Zetterstedt's type in the Copenhagen Museum, and 

 agree with Ringdahl that Stein's variabilis (at least the grey form) 

 is a synonym. 



6 (3) Scutellum uniformly brownish-black. 



7 (8) Dark markings on thorax distinctly divided up into stripes behind. 



Hind femora with rather fine anteroventral bristles on apical half 

 and some long fine posteroventral hairs on basal half 

 .... *2(3. exsurda Pand. 

 c? . Frons at narrowest part rather wider than 3rd antennal joint 

 with the orbits much narrower than the frontalia. Vertex not 

 greyish. Arista microscopically pubescent. Thoiax slaty-grey,
