506 ENTOMOLOGICAL NOTES 



Teph. Theora. Obscure griseo-viridis ; fem. telo nigro; 

 proalis fiisco reticnlatis. 



Head, between the eyes, somewhat ochreous; mesothorax and follow- 

 ing segments, dirty greyish -green, until the telum, which in the 

 females is black ; wings reticulated with brown, which forms a 

 stronger double irregular blotch on the costal margin ; another 

 near the middle of the lower margin, and a third towards the 

 tip ; — these three are at their edges united. The legs are pale. 

 (Breadth 3h lin.) {Mus. Soe. Ent.) 



This insect is nearly allied to Teph. Leontodontis of Meigen, 

 than which however it is less, and, in other respects, suffi- 

 ciently distinct. It is also related to Teph. Jiavicauda of 

 Meigen, from which it is readily distinguished by the colour of 

 the terminal segment; the three or four segments before 

 these have occasionally a pair of black dots on each. It is 

 one of the commonest species in Britain, having been taken 

 in abundance in Scotland, Cambridgeshire, Oxfordshire, &c., 

 and in the neighbourhood of London, at Hampstead, South- 

 gate, Coombe, Camberwell, Deptford, Birch, and Darent. 



Teph. Alethe. Nigra, proalis nigro contaminatis. 



Entirely black ; wings reticulated, and clouded with black. (Breadth 



3 lin.) {Mus. Soc. Ent.) 



Taken at Birch-Wood and at Southgate, in considerable 

 abundance, somewhat resembling Teph. jlamcauda in the 

 mai'kings of its wings, but is constantly less. 

 Teph. Hebe. Brunnea ; mesothoracis scutello'^ ochraceo ; 



proalis hyalinis fasciis sex brunneis longitudine variis. 



Brown ; with the head between the eyes, and the legs paler ; the 

 scutellum of the mesothorax ochraceous : the wings are very 

 transparent, with six transverse fasciae, and the costal margin 

 brown, — the first, counting from the insertion of the wing, is 

 broad, obscure, and extends from margin to margin ; the remain- 

 ing five are very distinct; the second is medial, not reaching 

 either margin ; the third touches the upper margin, and extends 

 three-parts of the way towards the lower ; the fourth is very short, 



* I use the term scutellum more in conformity with general practice than to 

 express any belief of my own in its accuracy. 1 suspect the part in question will 

 prove tlie fourth section of this segment, or the mesothorncic postsculellum. I 

 prefer, however, adhering to a possible error, to the risk of falling into a new one.
