1890.] OF THE FAMILY BUTHIDjE. 13o 



inferior and lateral surfaces of first three segments smooth and keel- 

 less ; inferior surface of the fourth keelle-ss, but granular ; inferior and 

 lateral surfaces of the fifth keelless, but thickly and coarsely granular ; 

 the whole of the under surface of the tail marked with serially 

 arranged setiferous pores. Vesicle smooth above, thickly hirsute 

 and weakly granular below ; subaculear spine small and blunt. 



Palpi setose, especially on the fingers: humerus marked above 

 with the customary anterior and posterior granular keel ; anterior 

 surface bearing larger and smaller granules : brachium furnished in 

 front with a few tubercles, the rest of the segment smooth and rounded, 

 without keels or granules : maniis smooth and rounded, slightly 

 wider than the brachium, neither keeled nor granular and not armed 

 with a tooth : dactyli short and curved, in contact throughout, being 

 neither lobate nor sinuate ; denticles arranged as in the preceding 

 species. 



Legs hirsute, but almost wholly smooth; tibicB of the two pos- 

 terior pairs spurred. 



Pectines armed with 17 approximately similar teeth ; the basal 

 tooth being only slightly thicker and slightly shorter than the rest. 



Stigmata small and slit-like. 



Measurements in millimetres. — Total length 28"5 ; cephalothorax 

 length 4*2, width 4 : length of tail 17; of first two segments 4 ; of 

 fifth segment 3"5 ; of vesicle and aculeus 3"8 ; width of first segment 

 2'5, of fifth 2'3 ; humerus length 3 ; brachium length 3*7, width 1:5 ; 

 width of manus 1*7 ; length of ' hand-back ' 2, of movable dactylus 

 3-2. 



Two specimens ( $ ) from Natal ; one presented by Ernest 

 Howlett, Esq., the other from the collection of Gueinzius. 



This species may be recognized by the wide, undivided, median, 

 longitudinal, yellow band on the abdomen, by the wide black band 

 on each side of it, by the absence of fuscous patches on the upper 

 surface of the four first tail-segments, by its fuscous hands and 

 almost wholly ochraceous humerus and brachium. It differs, in 

 addition, from U. triangulifer (Thor.) in being much smoother both 

 above and below. 



Uroplectes flavoviridis, Peters. (Plate XIV. fig. 5.) 



Monatsb. Ak. Wiss. Berlin, 1862, p. 516. 



Colour. Upper surface of trunk and the whole of the tail of a 

 dark shining green ; extremities of the appendages and the sternal 

 surface pale green or ochraceous. 



$ . Gephalotliorax thickly granular ; the central depression well 

 marked, deep behind ; the ocular tubercle distinctly sulcate and 

 smooth ; anterior border widely and lightly emarginate. 



Tergites granular, the first six furnished with a well-developed 

 though nearly smooth median keel ; the seventh more granular than 

 the preceding, furnished with two granular keels on each side and 

 a median granular prominence in its anterior half. 



Steriiites bisulcate, punctured, smooth, the last only very feebly 

 granular laterally and not carinate.
