PTERODONTIA, 167 



spot, leaving a pale margin all round of uniform width; underside 

 of tliorax shining black. Abdomen with 1st segment wholly black ; 

 2nd broadlj black in the middle, s© that about one-fourth of the 

 segment on each side i-emains pale ; 3rd and 4th segments eacli 

 with a blackish triangular mark, with rounded angles and with the 

 apex directed backwards, both segments bearing also a black 

 rounded spot towards the anterior angles ; 5th segment wholly 

 black, except for a narrow yellow hind border with a tooth-like 

 extension in the middle ; 6th segment similar, with rather stout 

 genital organs. The yellow antennae, which are placed so low 

 that they touch the front coxae, consist, so far as can be seen, of 

 a cylindrical joint and a globular one, half as large as the 1st ; on 

 the latter is a yellow bristle, which at a magnification of 27 (Zeiss) 

 is seen to be composed of two hairs separated at the base. The 

 distinct ocelli are placed on the occipital margin almost directl}^ 

 over the antennae; eyes very hairy. Whole body with short 

 pale pubescence, with which some darker hairs are intermixed 

 only on the blackish n)arkings and on the middle coxae. Legs 

 wholly pale ivory-yellow, with large yellow empodia, the claws 

 wide apart, black on the apical half. Wings hyaline, with yellow 

 veins, the costal projection rather pointed. 



"The species is distinct from Pt. ivaxelii. King, with the type 

 of which in the Berlin Museum I have compared it, and from 

 Jiavipes, Macq.,by the entirely pale coxae and femora." {Lichtwardt.)

2 . Head with eyes very large, black, closely contiguous, rather 

 thickly pubescent ; occiput moderately puffed out, dark grey ; 

 vertex small, three dull red ocelli. Antennae yellowish, the three 

 joints nearly equal in length, but the 3rd rather the longest, with 

 three very long straight bristly hairs at tip. Proboscis distinct, 

 but short, cylindrical, pale yellow. Thorax brownish yellow, the 

 dorsum mainly occupied by a large black shining spot, which is 

 continued forward as a stripe as far as the anterior margin ; sides 

 of thorax black, except the mesopleura, which is brownish yellow, 

 with a square black spot in the middle. The whole thorax 

 covered with brown or yellowish hair, concolorous with the colour 

 of the surface, Scutellum brownish yellow, pubescent, with a 

 large basal, nearly circular, black spot. Abdomen brownish yellow ; 

 1st segment all black ; 2nd all black, except towards the sides ; 

 3rd, 4th, and 5th with a black spot on each segment, widest in 

 front, extending from fore to hind margin, except on the 5th 

 segment, where the spot fails to reach the latter; these spots
