founded, Meinert's species, as he describes it, will be distinct in the 

 possession of the followiuo- characters : 



Claw of preheusorial feet reaching beyond the frontal margin of the 

 head. 



Cephalic lamina transversely sulcate near its posteiior margin. 



The anterior corners of the basal lamina covered by the ctpbalie 

 lamina. 



The basal lamina four times broader than long. 



The dorsal laminse sulcate. 



The first pair of legs equal to second pair. 



Anal legs shortened and thickened in the female. 



Anal pores wanting. 



Escaryus liber, sp. nov. 



Body slender, slightly narrowed anteriorly and posteriorly, waxy 

 white, sparsely hirsute. 



Autennse of moderate length, the last joint scarcely as long as the 

 two preceding. 



Cephalic lamina considerably longer than broad (4:3), posterior cor- 

 uers much rounded ; basal laminamore than twice as broad as long (7:3). 



Labrum entirely free, the anterior and posterior margins nearly 

 straight, subparallel except at the sinus ; transverse wrinkles run from 

 the ends to the middle. The ends notched, and two notches on the 

 anterior margin run behind the teeth, which number about thirteen. 



Mandibulary stipe with one or two spines beyond the dentate lamellae.. 

 Teeth of dentate lamellse with rounded points. 



Labial sternum not different from that of U. phyllophilus. except that 

 the processes of the palpi are more deeply divided into papillse. 



Preheusorial feet not attaining the frontal margin of the head ; sternum 

 much broader thau long (3 : 2), longer than coxa (3 : 2), moderately sinuate 

 in front, without prosternal teeth; coxa with a small, obtuse tooth, or 

 unarmed; other joints armed; claw strongly curved, with a small^ 

 obtuse tooth at base. 



Scuta not sulcate; prescuta long, increasing posteriorly, where they 

 become more than half as long as the scuta (3:5). 



Spiracles round, largest in front (0.04 millimetres), decreasing poste- 

 riorly, the last measuring 0.02 millimetres. 



Sterna short in front, becoming very long caudad, bisulcate, the 

 anterior ones medianly foveolate. 



Pleurse of last segment moderately inflated, with about seventeen 

 pores of different sizes on each side; last ventral i)late narrow, oblong, 

 the posterior corners rounded, the sides scarcely converging. 



Feet gradually longer posteriorly, the first and penultimate pairs 

 shorter than the others; anal legs slightly longer than the penultimate,
