uralense. The males are, all but one, H. detritum*; the exception 

 appears to be H. marrinatum; the females are in poor condition. It 

 is reasonable to assiime that what is now considered to be H. detri - 

 turn (or, in part, "H. scupense " ) was treated by Schulze in^part 

 as H. uralense and Tn part as H. volgense , though, he overlooked 

 other species in the same collection and referred to them by the 

 same name.

According to Galuzo 1935, the H. asiaticum of Olenev is H.

HOSTS 



Domestic cattle and horses are the most common hosts of H, 

 detritum , all stages of which feed on the same kind of animal. 

 Sheep and goats are sometimes attacked. For the Soviet Union, 

 Pomerantzev (1950) lists cattle, horses, donkeys, pigs, camels, 

 sheep, and hares; and, for nymphs, especially cattle and horses, 

 Man is apparently commonly attacked under local conditions.

 that these specimens did not resemble the latter form.
