Genus 
ATYLOTUS, Osten Sacken. 
Atylotus fulvus, Mg. 
Plate 1 8. 
The general ochreous colour of the body will serve to distinguish 
this species, which is one of the rarer of our British horse-flies. 
Rubbed specimens, however, look darker owing to the disappearance 
of the short silky golden hairs, which cover the body and produce 
the characteristic hue, and in the specimen figured in the plate these 
hairs are unfortunately wanting on the abdomen. 
The only British specimens of A . fulv us that the Museum possesses 
are a male, from Lyndhurst, New Forest, Hants, June 24th, 1897, 
and five females, from the same locality and Lyndhurst Road, 
June 29th and July 8th, 1897 (Lieut-Colonel Yerbury) ; Beau- 
lieu, Hants, July 15th, 1898 (Miss Gertrude Ricardo) ; and Kenmare, 
Co. Kerry, Ireland, June 30th, 1901 (Lieut.- Colonel Yerbury). The 
length of the male is 14J mm. ; that of the five females varies from 
14I to 15^ mm. The eyes of the male are usually without bands; 
those of the female are described by Brauer (loc. cit., p. 170) as "pale 
olive-green, with an oblique fine dark line and shot with several 
almost black round spots." In the male of this as of the following 
species an area in the upper half of the eye, running from the inner 
nearly to the outer margin, is composed of much larger facets than 
the remainder. 
Writing of A. fulvus Colonel Yerbury says that it is "a rare 
species," and that he has met with it " only in the New Forest, and at 
Glengariff and Kenmare in Ireland." 
The Continental series of this species in the Museum collection 
includes examples from Hungary, Switzerland, and Spain. According 
to Brauer it is generally distributed throughout Central and Southern 
Europe, and is also found in Scandinavia, Russia, and Asia Minor.
