Fig. 46.— Ungues and bristle of hind leg of Lipoptera ibicis 

 n. sp. a Ungues ; c basal process ; b and ^1 bristle 



are two groups of three, equidistant thick spines, two ocelli on the basal region of the head. 



The thorax is narrowed in front, widening out posteriorly ; the prothorax is a small plate 



extending across the thorax, openly wedge-shaped posteriorly. The mesothorax is the 



major area, and has numerous long thick needle-like spines ; it has a distinct humeral 



swelling over the mesothoracic legs. In front, just behind the prothoracie legs, are two 



swellings, somewhat ragged or irregular apically, the remnants of the wings. The 



scutellum is uni-lobed with apparently six large 



black bristles on the posterior border. The 



whole of the thorax is fused into one piece. 



There is a distinct median and transverse suture. 



The abdomen is oval, deeply indented apically, 



the apical segments being enclosed in .i pit 



formed by the prolongation of the anterior 



segments as two blunt processes on each side. 



The whole abdomen is covered with thick, 



black thuru-like spines, which are particularly 



long on the apices of the lateral lobes ; the 



small imbedded apical segments have fine hair-like chcetie. 



Anterior legs with the short thick femora spinose ; the tihite with a few fine hairs and a 

 strong internal apical spine ; basal tarsal segment spinose, the rest hirsute ; ungues much 

 curved, thick, the inner edge finely serrated with a large blunt basal process ; the median 

 process short and thick, with hairs on each side, terminating bluntly ; mid legs very similar 

 but shorter and thicker than the fore and the ungues thicker ; in the hind 

 legs the tibiae are also spinose and the ventral tarsal spines are more 

 pronounced than in the anterior legs, and the ungues are less curved, and 

 the median plumose spine is acute 

 Lfii'ith. 4 to 4-5 mm. 



Mule. Three ocelli present. Thorax narrower and smaller than in 

 the female, the scutellum relatively larger and three lobed, and the 

 spines on the thorax are fewer. Abdomen more rouiiiled apically than 

 in the female, and the external genitalia (Fig. 47) are prominent and consist of two 

 chitinous lateral valves with the penis projecting between. The ungues are rather shorter 

 and broader, and the median bristle is thin and acuminate with a few hair-like spines 

 pointing forwards on each side. 



Length. 4 mm. 



Locality. The Sudan, Eed Sea Province. 



Ohservatioiin. This Pupiparous dipteron was found by Dr. Crispin on an Ibex. It 

 resembles MelopIuiyHa but does not belong to that genus on account of having ocelli. 



The IJpoptents* are winged at first but their wings are cast when they take up their 

 abode on their host. In this species the areas to which the wings are attached are very 

 marked. 



The male has quite a ilitt'erent shaped process between the ungues to tlie female. 



The description is drawn up from a male and female mounted in xylol balsam. It 

 is closely related to fJiniptcni cervi, Nitzsch, but differs from the specimen I have.
