by the comparatively small size. Apparently common in such moun- 

 tain districts as Dolgelly, the Lake District, and the Scotch High- 

 lands, but I have also taken it at Brockenhurst. 



24. H. h'xkeri, Strobl : Another large species of the H. qnadri- 

 ritiata group, distinguished by its frons being wholly grey up to the 

 front ocelluM, but deep black above that and on the occiput ; thoracic 

 stripes blurred together laterally, and the acrostichal In-istles 4-wide 

 on at least the front part. Taken by Col. Yerbury at Aviemore, Nairn, 

 and Brodie, from July 18th to August 1st, 1905. 



25. H. carinthiaca, Strobl : A rather common species which may 

 })e known by its yellow halteres, and a peculiar diamond- shaped grey 

 spot on the deep black occiput. Darenth, Martham Broad, Coniston, 

 Porthcawl, Penzance, Lyndhurst, Studland, Oxford, Orford, &c. 



26. H. hraueri, Strobl : I am obliged to introduce this species 

 as British, because I possess an old gummed specimen from the late 

 W. Wilson Saunders' collection, though I do not know its locality. 

 The species is very readily known by the pale three basal joints of the 

 hind tarsi. Only three specimens (all males) have been previously 

 recorded, two being from Lower Austria, and one from Silesia. It is 

 also notable that H. argyrosoma, Strobl, of which only five females 

 were known, has also occui-red in England, Mr. J. J. F. X. King 

 having taken one at Brockenhurst on July 6th, 1907, and this confirms 

 Strobl's suggestion that the two are only the sexes of one species. 



27. H. cinereomicans, Strobl : I believe that this is a not un- 

 common species. It bears some resemblance to H. inanicata and 

 H. canescens, but the male is easily distinguished by the three long 

 bristly dorsal hairs on the long moderately dilated basal joint of the 

 tarsi. 



28. H. heterogastra, Now. : A male of this large species was 

 caught at Wormsley on July 12th, 1907, and answers well to Strobl's 

 description. 



29. H. cingulata, Dahlb. : I believe that a fairly common greyish 

 species allied to H. Jiavipeff (which is not an Oreogetou) should come 

 vmder this name. I have specimens from Ringwood, Colwick, Orford, 

 and Porthcawl. The undilated basal joint of the front tarsi of the 

 male will distinguish it from all known British species of the genus 

 except H.favipes. 



30. (Edalea apicalis, Lw. : Col. Yerbury took two females, which 

 answer exactly to the description of this very little known species, at
