14 LIST OF DIPTERA. 



Antennae tawny, black towards the tips. Palpi pale yellow 

 Thorax bright bluish green, with whitish down ; scutellum with tes 

 taceous spines. Abdomen testaceous ; segments black along the 

 hind borders and with a triangular black spot on each side ; tip 

 black. Legs testaceous ; tips of the hind femora brown ; hind tibiae 

 brown with a tawny middle band. Wings limpid ; stigma testa- 

 ceous. Length of the body 3 lines ; of the wings 6 lines. 



This species much resembles A, tibialis, but is larger, and 

 sufficiently distinct in other characters, and especially in the branch 

 of the cubital vein which is longer, and more oblique and curved, 

 and resembles that of most species of Beris.

3. ACTINA SIMILIS. 



Chalybea ; abdomen nigro-cceruleum ; pedes nigri, femoribus fcem. 

 basi plus minusve jiavis ; alcefuscce, ad costam nigro-fuscce. 



Stratiomys similis, Forster. 



This species has the third externo-medial rudimentary, and 

 thus has most resemblance to the species of Beris in which it is 

 wholly wanting. It is mentioned as British erroneously in the first 

 ' Catalogue of Diptera.'

Mediastinal vein ending at beyond half the length of the wing. 

 Subcostal ending at very little beyond the mediastinal. Radial 

 ending before two-thirds of the length. First branch of the cubital 

 straight, short, ending at about half the distance between the radial 

 and the second branch which ends at some distance in front of the 

 tip of the wing. Four complete nearly straight externo-medial 

 veins. Subanal vein united to the anal at some distance from the
