In this species also the head of the male is large, and strongly 

 concavo-convex, with a conspicuous area of large facets in the upper 

 half of each eye ; the female may be recognised by the exceptionally 

 broad front (space between the e}'es), and by the shape of the shining 

 black callus between the lower angles of the eyes, which is large and 

 square, and occupies practically the whole width of the front. Brauer 

 {loc. c.it, pp. 201-202) describes the e}-es of the male as " grey above, 

 green in the lower fourth," with a dark transverse band between the 

 large and small facets ; the e)-es of the female are stated to be 

 unhanded. Two British males of this species are each 14^ mm. in 

 length ; seven females measure from 13 to 15 mm. 



According to Colonel Yerbury, Tabanus cordiger is " usually a rare 

 insect, but occurs plentifully in the Abernethy Forest, Inverness-shire, 

 in July and August." The British series in the Museum at present 

 consists of two males and se\'en females, the localities and dates of 

 which are as follows: Nethy Bridge, Inverness-shire, N.B., July 26th —
