326 COSTA RICAN EPIGOMPHUS (oDONATa) 



I have also a female taken by the late Professor P. BioUey, but without 

 precise locaHty. 



Recorded from Cachi, 3280 feet (1000 m.) and Carrillo, ca. 300 m., in the 

 Biologia, and by Dr. Ris from Infernillo, Reventazon [ = Juan Vinas], 1000 

 m., 1913. 



5. E. verticicornis Calvert 



Tuis, 2460 feet (750 meters), June, 1907, 1 d", 1 9, taken by C. H. Lan- 

 kester. (These are the type and allotyi^e described in the Biologia and now 

 in the collection of The Academy of Natural Sciences of Philadelpliia). 



In August, 1909, I noted one female of this species from Tuis, taken by 

 Lankester, in the Museo Nacional at San Jose, Costa Rica. 



6. E. subobtusus Selys 



Juan Vinas, near the Rio Reventazon, 2500 feet (760 meters), June 28, 1909 

 1 cf, 1 9, Calvert. 



Quebrada Honda, ca. 3450 feet (1050 m.), August 1, 1909, Calvert. 



Mountains south of Aguacahente, ca. 4500 feet (1370 m.), May 20, 1909, 

 1 9. in narrow lane in low woods (second growth, scrub), resting on shrub; 

 Calvert. 



Tuis, 2460 feet (750 m.), June 1907, 1 d", taken by C. H. Lankester (Acad. 

 Nat. Sci, Phila.). 



Recorded from Irazil and Cachi, 3280 feet (1000 m.) in the Biologia, and 

 by Dr. Ris from "Tuis, Turrialba 1000 m., 1913; Orosi, Irazu 1500 m. V, 

 1912." 



7. E. armatus Ris 



Guapiles, Florida road west of the town, in the forest, June 3, 1909, 1 9 , 

 Calvert; June 5, 1909, 1 9 taken by Messrs. Schaus and Barnes. 



Described by Dr. Ris from "Costarica: 2 cf, 1 cT (das 9 'Finca Hun- 

 driesser')." 



Dr. Ris remarks: "Gestalt und Farbung der sehr eigenartigen 

 in dieser Gattung vereinigten Formen lasst in ihnen Waldtiere 

 vermuten und die Herkunft des immerhin noch sparlichen Ma- 

 terials spricht im selben Sinne. "« My own observations fully 

 bear out this conjecture, although individuals and species may 

 occur in the thin woodlands along water courses, as in E. sub- 

 similis at Turriicares. 



From the preceding list of localities it will be seen that five of 

 the seven Costa Rican species have thus far been found only on 

 the moister Atlantic slope of that country with its more extensive 

 forests; one species (subsimilis) L at present known only from 

 the Pacific side and one species (quadracies) from both slopes. 

 Too much weight must not be laid upon these statements until 

 they have been tested by more thorough collecting.
