 Altliuiigli it is I'ssi'iitiitlly a caniiu' pest, it may also !"■ fDiiiid on otlur aiiiiiials. It occurs 

 in Africa. India, Persia and in Southern Europe. 



The Horse Forest Flv ( //. tqniiKi \j.) differs from tlie former in lieing darker, and in 

 having the scutellum dark with a median pale patch (riilr Fig. 49). 



The Camel Forest Fly ( //. r,iiii<liiiii, Iiea<h> is miirh larger than the preceding, and 

 can also lie distinguished liy its seutellar markings. 



This species has also beeu sent nie from the West Coast (Seuegainbiii).

The •■ featlier-liristle " between the ungues in //. ruiiifHiiii is simple except at the base, 

 not spiny as in the others, nor can I detect the pad-like pulvilli seen in the rest. The 

 diflferences are very marked in the claws and central processes, as shown in the figures 

 (x 1! (■ and II, Fig. 58). 



The pii|)aria of all these four species are jilaced amongst the hairs of the host. They 

 are all very similar in form (Fig. 50). The color is deep brown when mature. 



The markings on the scutellum are constant in all the Northern African specimens I 

 have seen, but according to Austen they are variable, so cannot be relied on to separate 

 the species. Tlii' (igiires of the wings and the feet will, iiowever. sntlice to separate them, 

 and I have invariably been able to do so niy.selt by the seutellar markings.
