thus concave inner edges ; their anterior e-lge with a slight 

 central angle ; in their inner corner there is a hole (?). Hairs: 

 on the anterior shield a pair of hairs, slightly longer than 

 the width of the shield. Inward of this pair a pair of minute 

 hairs. On the lateral shields a minute hair outside of the 

 above mentioned hole, and laterally the ventrilateral hair 

 (which has become dorsal) as long as the shield itself. On 

 the posterior shield the following minute hairs : a pair quite 

 near the anterior edge; a pair on a line with trochanteres III; 

 a pair on a lice with trochanteres IV ; and a pair on a line 

 there where the abdomen becomes equal in width. On the so- 

 called horns a minute hair quite laterally where the horn 

 begins ; further backward an almost horizontal short pin ; 

 behind this pin a crooked short hair directed backward ; in 

 the outer angle of the top of the horn a long hair, almost 

 as long as the greatest width of the body ; in the hyaline 

 membrane behind the top of the horn a long thin hair as 

 long as its nabour ; in the inner rounded angle of the top of 

 the horn a strong thorn, directed inward towards its congener 

 of the other side ; and before this thorn, and opposite to the 

 little outer pin, a very thin short hair directed inward towards 

 its congener of the other side. The openings of the 

 excretory glands on a line with the distal ends of 

 trochanteres IV. 



Ventral side (Fig. 18). Epimera I free, proxiraally 

 a very little bent outward ; epimera II ^roximally a very little 

 bent outward ; the prolongation of the dorsal anterior dark 

 margin crooked inward ; epimera III shorter than the other 

 epimera, bent inward, and distally touching the edge of the 

 body ; epimera IV again slightly longer, with proximal exter- 

 nal long epimerite, and distal external shorter ditto, of which 

 the first part has a circular frontal appendix. Shields: 

 outside of epimera I and II the narrow coxal plates ; the 

 lateral shields include the ventral prolongations of the dorsal
