Family SOLPUGID^. 



Apertures of the abdominal respiratory organs not protected by 

 a pair of serrulce. Tarsus of palp not narrowed at its base, 

 immovably united to tibia, from which it is separated by a sutural 

 line. Basal portion of claws smooth, hairless. Anal segment large 

 or small. 



Distribution. As stated above under Order Solifugse. 



Subfamily DiESIIN/E. 



Kraepelin, Jb. JIamb. wiss. Arnt. xvi, p. 221, 1899. 



Anal segment, small, roundish, almost completely divided into 

 a right and left half by the anal aperture, which extends nearly to 

 its upper edge. Anterior border of head not transverse, light 1\ 

 produced. Mandible with stridulating-ridges highly developed. 

 Flagellum membranous, with incurved edge or edges, longish, 

 subovate, rounded at one extremity, pointed at the other, movably 

 articulated to the inner side of the upper jaw by a single point of 

 attachment somewhat resembling a pin-head. Tarsus of 1st leg 

 without claw, of remaining legs spined beneath. Tibia; of 2nd 

 and 3rd legs spined above. 



Distribution. Mediterranean, Ethiopian, and Western Orient,! I 

 Regions ; America from Texas to the Argentine Republic. 



One tudian genus. 



* Apical tarsal segment considerably longer than the second, spine-armature 

 also very abnormal; the basal segment armed with 5 Bpines behind and Id 

 spines in Front, 4 being Bituated close together, 2 above and 2 below at the 

 base, and (> in a row ; second segmenl with a pair of Bpines, apical Beguient with 

 a single posterior spine. The Itb leg is present only on one Bide of the bod3 

 so it is not possible to judge of I he constancy of this peculiar Bpine-armatun 

 nor of the value of the unusual inequality in length between the second and 

 third tarsal segments.
