had its hole in a dry corner beneath the plate of a long 

 veranda. One day I observed it dragging a victim along 

 a gravelled walk that was parallel to the veranda ; the 

 small stones and grit made its progress very difficult 

 After very trying struggles with these impediments it 

 displayed a remarkable degree of intelligence, by which it 

 gained its ends. It altered its course and made for the 

 veranda, ascending the smooth, painted board that 

 adjoined the gravelled walk. After slowly traversing 

 seven inches of perpendicular, it came to a rounded 

 beading which projected outwards. Now came its supreme 

 moment of physical exertion. The body of the spider 

 apparently was too heavy to render the aid of wings 

 available. After several pauses in its progress it slowly, 

 yet surely, surmounted the difficulty presented by the 

 projecting beading, gained the level boards of the veranda, 

 along which it travelled rapidly with its burden, which it 

 sometimes dragged, sometimes pushed before it. By the 

 expenditure of great exertion in surmounting the beading 

 it gained a smooth and level run to its home of thirty- 

 nine feet" 



In Mr. Kirby's Catalogue all the species are des- 

 cribed under the name of Priocnemis, which name, however, 

 must give place to Salius. 



a. Fulvous species. 



Salius wakefieldi Kirby. 



This is by far the commonest of the Pompilidce. In a 

 fresh state the head and thorax are thickly covered with 

 golden pubescence; but with age this gets abraded, 

 the parts then appearing quite bare and shining. 



Salius marginatus Sm. 

 A much rarer species than 5. Wakefieldi, to which it 

 has a great resemblance when the latter has the head and
