 Gayiidali speciineiis have been considered as a distinct sub- 

 species, foi" which the name of scohiniild sub-s]). iiov. is proposed. 



(a) J mat.: length 70 in m ; diameter 6.50 m/m ; 56 

 segments; one segment apodous ; 103 pair of legs. 



(b) $ mat.: length 77 in/m; diameter 7.50 m/m; 55

(layndah, Queensland. 



Chestnut, with darker metazonite. l^egs and antennte 

 chestnut. 



Head smooth, shining, with four subequidistant labral dim- 

 ples ; median sulcus almost obsolete. Eyes rounded, divided 

 by two-and-a-half times the diameter of one of them ; ocelli 

 small, distinct, arranged in 6-7 series to 9-}-10-|-9-j-8-j-8-(-5 = 

 ■49 to 9 + 9 + 9 + 9 + 8 + 5 + 1 = 50. Antenna very short, 

 reaching the middle of the following segment, wide apart, the 

 distance between the sockets ("2.50 m/m) equal to more than 

 the length of the four proximal joints. The three basal joints 

 almost naked, the following gradually more pilose; four sensory 

 cones. Micrometrical measurements of the joints: 1st joint 

 0.602 m/m ; 2nd, 0.688 m/m ; 3rd, 0.559 m/m ; 4th, 6.559 

 m/m ; 5th, 0.516 m/m ; 6th, 0.473 m/m ; 7th and 8th, 0.086 

 m/m; total length 3.483 m/m. Diameter of 2nd joint 0.537 

 m/m ; of 6th, 0.516 m/m. 



Mandibular stem of male with the anterior angle acute, 

 directed downwards. 



First segment falling a good way short of the ventral surface 

 of the second ; surface almost smooth dorsally, ]e«.s so on the 

 sides ; anterior margin straight, sides rounded or with a faint 

 ti'ace of a rounded angle. Marginal sulcus moderatelv long, 

 scarcely reaching the inferior level of the corresponding eve. 

 Seci)nd segment flattened and sulcate on the ventral surFace, 

 the sides (if which are rounded, or even somewhat swollen. 



Scobina from about the ninth to about the twenty-second 

 segment very small, the tirst and the fourth to fifth last are 

 dot-like ; it is (accidentally ?) missing on the seventeenth 

 segment. The distance between the dimples equal to about 

 eight times the diameter of one of them. Dimples sub-cii-cular, 

 with smooth bottom ; the striate area scarcely as long as the 

 dimple, rounded, with very few sti'ife.
