9. HYPOPHl'LLUS Lw. 



1 (2) Front tarsi with last joint very much dilated 1. discipes Ahr. 



2 (1) Front tarsi simple 2. obscurelhis Fall. 



1. H. discipes Ahr. : I cauji^ht a male in July, 1880, which is labelled 



" Snailvvell ?." I do not know why I put the ?, as I believe 

 I know exactly where I took it ; possibly it is the date which 

 is doubtful. I caught a female at Bowiiess in Westmorland 

 on June 23rd, IS89, which almost certainly belongs to this 

 species. 



2. TI. obscurcUus Fall. : easily recognised by its long yellow genitalia. 



It has occurred in numerous localities from Clapton Leigh 

 to Inveran. 



10 ORTHOCHILE Latr. 



0. nigrocoerulea Latr. : I took a pair at Leigh in Essex on June 18th, 



1871, and a male at Lee in Kent on June 15th, 1875 ; more 

 recently I took a specimen at Wicken on June 27th, 1903, 

 and Mr. F. Jenkinson has taken several specimens in and 

 near Cambridge. 



11. GYMNOPTERNUS Lw. 

 All the species have black postocular cilia and black fringed squamae. 



1 (2) Femora mainly blackish ; middle tibiae thickened and twisted at tip... 



1. cupreuft Fall. 



2 (1) Femora yellow, or almost so. 



3 (4) Costa dilated on a streak near base 2. ceJer Meig. 



4 (3) Costa normal. 



5 (8) M^oderate sized species. 



6 (7) Antennae wholly black ; blackish-green species 3. metallivus Stann. 



7 (6) Antennae pale at extreme base ; steel-blue species... 4. chah/bseus "Wied. 



8 (5) Small species. 



9 (10) Face white 5. assimilis Stseg. 



10 (9) Face black 6. mrosus Fall. 



1. O. cupreus Fall. : a common species, easily known by its black 



femora, and the peculiar dilated and twisted tip of the 

 middle tibias of the male. 



2. G. celer Meig. : also a common species, easily recognised by the 



costa of the male being swollen for a rather long space near 

 the base. 



3. O. metallicus Stann. : I first found this in abundance in Epping 



Forest on June 16th, 1872, and I have since taken it in 

 Sussex, Suffolk, and Norfolk.
