SANTA CLARA 297 



I could think of was that the insect was attracted by the 

 perspiration, as has been noticed in some other species. 



My insect net these two days was often much hampered 

 by brushing against seeds (which we think of as autumnal) 

 which then adhered to it and tangled it up. These were 

 beggars' ticks very like our own Desmodium, small burrs a 

 quarter of an inch long and seeds resembling "Spanish dag- 

 gers" but narrower and having three prongs at the end 

 instead of two. 



By way of summary of the Guapiles-Guacimo trip, I 

 found on returning to Cartago that in the six days of June 

 I caught or definitely identified specimens of forty-four 

 species of dragonfiies, not one of which had I met around 

 Cartago; that of the forty-four, three had not been recorded 

 from Central America or Mexico and may possibly be en- 

 tirely new, one of the three representing a subfamily never 

 before met with in these countries; fourteen had not been 

 previously recorded for Costa Rica, and thirteen, although 

 known from the Pacific Slope of this country had not pre- 

 viously been recorded from the Atlantic side, so that thirty 

 of the forty-four were additions to knowledge of geographi- 

 cal distribution.
