insects to be stalked, that I was soon the third to go along 

 the trail, Mr. Barnes being in the lead and Mr. Schaus be- 

 tween us. Once, a couple of peccaries rushed across the 

 trail just in front of the latter; I was too far behind to see 

 them but the scent was still very marked when I reached 

 the spot where they crossed — it was like that of strong 

 onions. Mr. Barnes saw some red monkeys feeding quietly 

 in a tree-top, learning of their presence first by the debris 

 they dropped. He told me of them when we met later and 

 I went on to look for them but was unsuccessful. 



I did not go again to the Florida Road during my stay 

 at Guapiles, but Messrs. Schaus and Barnes repeated their 

 visit and brought me a few dragonflies, while in return I 

 gave Mr. Schaus any of the Lepidoptera I picked up that 

 were of interest to him. One of the dragonflies caught by 

 Mr. Barnes on the Florida trail was of especial interest, as 

 it belonged to the Cordulines, a subfamily of dragonflies 

 never before found in Central America or in Mexico except 

 once near Monterey in northern Mexico. It has in conse- 

 quence been supposed that the absence of this group was 

 one of the faunal characteristics of this region, but Mr. 

 Barnes' capture proved this idea to be erroneous. His 

 specimen has been described as Neocordulia longipollex; its 

 congeners are known at present only from Ecuador and 

 Brazil. The unexpected taking of this Corduline in the 

 Florida Road indicates how much collecting and study are 

 still necessary for a thorough knowledge of the neotropical 

 region, and how rash it is to generalize from collections 

 made during one visit only or at one season only. 



Mr. Schaus had collected Lepidoptera in various parts of 

 tropical America for over twenty years, of which three 

 were spent in Costa Rica. As a result of his long experi- 

 ence he preferred to collect in the forest, during the day- 

 time at least, since it was his opinion that specimens to be
