TURRUCARES AND RIO GRANDE DE TARCOLES 38 1 



The first, third, and fourth legs were successively longer, the 

 second were the shortest of the four. On the under side of 

 the fourth legs, near their bases, were some curious projecting 

 sense-organs. The upper surface of the fore-body possessed 

 a pair of eyes near the middle of its front edge and only 

 its hind portion was divided by cross-furrows into three 

 small segments. The hind body, on the contrary, which 

 was several times longer and lay behind all the legs, was 

 clearly marked off into ten segments. Unlike the scorpions 

 the hind end of the body was rounded and without any 

 sting or spine. I quickly got cyanide bottle and forceps 

 and secured the creature. Whether it would have annoyed 

 me as a bed-fellow, I shall never know, as no others appeared.

 building rattled and the whole house shook perceptibly. 



I wished to descend to the bottom of the canon of the 

 Rio Grande de Tarcoles. The information available at the 

 hotel was that there were two roads, one, seven or eight kilo-

 to the new electric plant under construction. I knew some- 

 thing of this plant from Mr. Clark and as this was the shorter 

 way and also insured a water supply I chose it. As I went 

 along the railroad to Cebadilla on April 12 I was able to 

 add another species or two to my present collection. In- 

 deed I had the same experience each day here, for apparently 

 dragonflies came up from the river or other stream to hawk 

 over the tracks in search of Insect prey — as I did. 



The road from Cebadilla for a mile at least was the one 

 I had taken the preceding day to the Rio Tizate. It was 

 probably the best in the country, well constructed, finely
