When the last Eeport of these Laboratories was issued, it was beheved that bed-bugs amhiJi,- 

 were responsible for the spread of the usually fatal disease known as kala-azar. Since 

 then, however, the researches of Capt. D. S. B. Thomson and Lieut. W. E. Marshall, E. A.M.C., 

 in this country, and of others woi'king elsewhere, seem to jn'ove that in this case, at any 

 rate, these obnoxious insects may possibly have been unjustly accused. 



Of the two species found in tiie Sudan, Gimex lectiilarins, Linn., occurs tliuughuut the 

 northern provinces, and has also been taken at Bor and other stations in the south. 

 Gimex rofiindatufi, Sig., has twice been taken — at Port Sudan and at Suakin — on pilgrims 

 from Yemen. Quite recently Captain Percival sent specimens from the Lado District. 



OESTKID.E 



Comparatively little is known at present of the (Estrldm of the Sudan. (Kflriia oris, L., Oisiridu: 

 occurs but does not appear to be conuuon. Mr. G. H. Storrar, Sudan Government 

 Eailways, bred out one specimen from a larva expelled from a goat at Eabak in 1909, and 

 occasionally it is noticed in Khartoum. Almost every hartebeeste which one kills on the 

 White Nile harbours the larvic of (Ustnis rariolosns, Lw. (Plate IV., fig. 4 and 

 figs. 15 and 16), and numbers have been received here, taken from hartebeeste shot 

 on the Blue Nile. The larva of another species of GephaJomijia — C. macnlata, Wied. — 

 is a common parasite of camels. 



A single adult specimen of dush-o- 

 pliihi^- flavipes, Oliv., was taken in 

 Khartoum in 1909 by El-Bimb. 

 Williams, Veterinary Department, and 

 an adult female of I laslrophilvs at^iiiuf, 

 Brauer (Plate IV., fig. 3), was captured 

 near Eenk in June, 1909, attempting 

 to oviposit on the legs of a donkey. 

 It was interesting to notice how panic- 

 stricken a donkey became on hearing 

 the distinctive hiun made by this fly 

 when on the wing. Three loose 

 donkeys, on hearing it, stampeded, 

 and when the cestrid transferred its 

 attentions to another donkey tethered 

 near by, this unfortunate animal, 

 unable to get away, rolled on the 

 ground, kicking as if in tlie last 

 stages of fright. These same donkeys 

 would show little or no excitement 

 when numbers of seroots were sucking, or attempting to suck, blood from them. 



^Ir. J. C. Walker, Suchin Government Eailways, has sent to these laboratories a 

 number of cestrid larvie taken from under the skin of an ariel gazelle shot at Khor Aral); 

 the larva of another species has been taken by Mr. MacMichael from a similar situation 

 in a dorcas gazelle killed at Gebel Sungur, N.W. Kordofan, and Captain Spencer has 

 sent yet another specimen from gazelles shot in the Eed Sea Province. Larvifi of a 

 different species living under the skin of a bohor reed-buck, shot on the Meshra-Wau 

 road in May, 1909, have been received from Col. Mathias, D.S.O., P.M.O. Egyptian Army.
