80 Genus Omithocloros 



hypostome ; two hairs posterior to the palps. Legs (pair I, 4 mm., 

 pair IV, 5 mm. I.) ; a single hump on all the tarsi. 



Neumann is probably correct in considering 0. papillipes a synonym 

 of 0. tholozani, since, as he informs us in a letter (6. iv. 08), in the copy 

 of Birula's paper which he had received from the author the latter had 

 crossed out the name papillipes and substituted " tholozani (Laboul- 

 bene and Me'gnin)." He points out, also, that the integument is similar 

 " corporis derma reticulato-rugosum." Birula's figures, however, are 

 difficult to reconcile with the description of 0. tholozani given above, 

 especially as regards the sides of the camerostome and the tarsi, so that 

 we have thought it best to insert them here, together with his descrip- 

 tion of 0. papillipes. 



Birula's specimens were collected in the Caucasus by Motschulsky. 



ORNITHODOROS MORBILLOSUS Gerstaecker, 1873. 



Lit. and Synon.: Ornithodoros morbillosus Gerstaecker, 1873, p. 464. 



Ornithodoros savignyi (Audouin) ; referred to this species by Neumann, 1896, 

 pp. 27-29, but Donitz, 1907, p. 23, who has examined the type, states that 

 it differs in the leg structure as noted below. 



Species based on a single specimen, measuring 6'3 x 43 mm., which 

 may be an abnormality. Donitz (1907) states that it differs from 

 0. savignyi in having 2 humps on tarsus IV instead of 3. Gerstaecker 

 only had Savigny's figure (1826) to consult in determining the differ- 

 ences. Origin : Lake Jipe, German East Africa, October 1862.
