(With Plates II and III) 
In the course of our entomological researches in Costa Rica, 
a brief outline of which has already appeared in ENToMOLOoG- 
1cAL NeEws,* I collected some Odonate larvae of a form hith- 
erto undescribed and which, it now appears, are certainly of 
the genus Cora. One of these was found at Peralta, Costa 
Rica, March 24, 1910, in a shallow brook in the woods west 
of the railroad station, clinging to a submerged stone. The 
altitude was about 335 meters, or 1100 feet. This larva died a 
few days later and was preserved in alcohol. A second is 
recorded in our diary, from Juan Vifias, April 27, IgIo, as 
follows: “About half a mile farther [westward from the 
farther waterfall along the railroad from Juan Vifias station] 
is a third fall, or rather cascade, reached by a little trail 
through a bit of exceedingly thick damp woods full of wild 
ginger [Costus sp., Costa Rican name cafiagria], heliconias,
