ible elevation or small knob. When the species of Hetaerina 

 are carefully studied, other valuable specific characters will 

 be found in the prothorax. 



In macropus the brown tips of the wings are more evident 

 in teneral specimens than are the red tips in tenerals of other 

 species where the hind wings or all four wings are red-tipped 

 in the adults. 



10. Hetaerina miniata Selys. 



Guatemala, Los Amates (9, 15), Puerto Barrios (15), Santo Tomas 

 (9, 13. 15) ; Honduras, San Pedro Sula (3, 5, 9) ; Canal Zone, Panama, 

 Rio Mazamba (2), Rio Sardanilla (2, 7, 9) ; Colombia, Cristalina (2, 

 3, 9), Maraquita (2, 3, 9) ; Venezuela, El Guayabo (2), La Fria (2, 9), 

 Tachira (3, 9). 



The South American specimens average slightly larger 

 than those from Guatemala and Honduras, and the basal red 

 on the wings of the males is more extensive. The Canal Zone 

 material is insufficient in quality and quantity to determine 

 its status. 



This species has been recorded for relatively few localities, 

 and yet at such streams as at San Pedro Sula, Cristalina, and 

 La Fria it seems the most successful species. For example, 

 four species of Hetaerina occur at San Pedro Sula, and of 

 the total number collected there over 65 per cent were miniata; 

 at Cristalina, also with four species, of the total number col- 

 lected over 75 per cent were miniata; and at La Fria, with 

 three species, of the total number collected over 88 per cent 

 were miniata.
