The First Central American Corduline. 

 By PHILIP P. CALVERT. 



In 1897, Prof. G. H. Carpenter, in an article on the geo- 

 graphical distribution of the Odonata,* pointed out the absence 

 of the Cordulinae from Mexico and Central America. Not 

 having succeeded in finding any specimens or records of this 

 subfamily from these countries (except a single mention of 

 Macronia larvae from Northern Mexico), when preparing the 

 account of the Odonata for the Biologia Centrali Americana,^ 

 I have emphasized in a recent paper:j: the absence of the Cor- 

 dulinae as one of the characteristics of these areas. As an un- 

 doubted member of the group has now been discovered in 

 Costa Rica, I wish to correct the erroneous idea for which I 

 have stood sponsor. 



In June, 1909, while enjoying the hospitality of the United 

 Fruit Company, at the house of Superintendent E. W. F. Reed, 

 at Guapiles, Costa Rica, it was my good fortune to find there 

 Messrs. William Schaus and John Barnes, whose labors on the 

 Lepidopterous fauna of Costa Rica are the most extensive yet 

 undertaken and to whose knowledge of the country I am 

 greatly indebted. While at Guapiles we collected Lepidoptera 

 and Odonata, sometimes together, sometimes separately. On 

 one of the latter occasions, on June 4, 1909, Mr. Barnes took 

 a single male of the species described below, in what is locally 

 known as the Florida road, a trail passable for horse and pedes- 

 trian, running westward into the virgin forest from near San 

 Jacinto, a hacienda a few miles west of Guapiles. The eleva- 

 tion of Guapiles accepted by Prof. Pittier is 300 metres, and 

 that of the locality here in question can not be very different. 



Of the Corduline nature of this male there can be no doubt 

 as it possesses the following characters laid down for that sub-
