Legs yellowish, Avith the knee joints sometimes very narrowly darkened, 

 clothed witli short brownisli-yellow bristles (all the bristles in this species have 

 a tendency to ajjpear brownish), front femora the stoutest, and all the tarsi 

 gradually dilated towards the tip, with tlie last joint produced at each corner 

 (fig. 3), ungues large, yellow with black tips, pulvilli large and pale, empodium 

 well developed and pectinate on the lower half, the basal joint of hind tarsus 

 seen fi'om above is not dilated and about equal to or slightly longer than the 

 next joint, but it is considerably dilated downwards, more at the base than at 

 the tip. Bristles on the legs by no means strong, on the middle femora there 

 is a short black bristle in front near the tip, on the middle tibiae beneath only 

 • the apical spur-, antero-dorsally two or three small bristles, and dorsally the 

 usual pre-apical bristle, on the hind tibiaj the pre-apical bristle is inconspicuous, 

 one or two small apical spurs are present beneath at the tip placed somewhat 

 anteriorly. 



Wings (fig. 4) of normal size, brownish-yellow, especially about the costal 

 margin, subcostal ending in costa just before the radio-cubital fork, radial and 

 cubital gradually curved up to costa, the cubital ending therein before the tip 

 of the wing, and the penultimate costal segment longer than the last, discal 

 and i)ostical veins continiied faintly beyond the postical cross vein to, or almost 

 to, the wing margin, base of costa with only short bristles. Halteres pale 

 yellow. 



9 . Like the male, except for the great extension dorsally of the yellowish 

 membraneous part of the abdomen which leaves only shallow chitinous hind- 

 marginal plates to all the middle segments, though the ventral chitinous plates 

 are noi*mal in size. The membraneous sides are studded with short stub))y 

 bristles as in the male, but the ]jristles on the disc are confined to the chitinous 

 plates and their immediate neighbourhood. The first segment appears to be 

 mainly greyish-black, but the second to fourth segments are yellowish with the 

 shallow, pre-hind-marginal chitinous plates brown (deepest on the fourth 

 segment), the fifth and sixth segments are narrow normal segments. The 

 ovipositor is somewhat flattened, nearly as wide as the last abdominal segment, 

 and bears a few long hairs at the tip. 



This species vai'ies somewhat in colour from yellowish-browu to 

 brown, and iu size from 2 to 2^ mm.

In 1838 Meigen described a Limosina sacra (Syst. Beschr. vii, 409) 

 foimd by Dr. Waltl on the under-side of Ateiichus sacer in Spain, and 

 this has been recognised as occurring upon A. cicatricosns, Luc, in 

 Spain (Czerny, Verh. z.-b. Ges. Wien, lix, 278 (1909), and upon A. lati- 

 collis, L., and A.iyvncticoUis, Latr., in Algeria (Lesne, Bull. Soc. Ent. Fr. 

 1896, 162). I have examined two males of what is probably this species 

 iu the British Museum Collection, taken by the Rev. A. E. Eaton near 

 Bone, Algeria, upon the big coprophagous beetles common iu that
