The two females at hand agree in all important features with the 

 original description. We would note that the cephalic tibiae, in 

 addition to being well supplied with hairs distad on all but the dorsal 

 surface, have the distal margin ventrad armed with a very closely 

 placed fringe of chaetif orm spines ; these, due to the size of this spe- 

 cies, being more conspicuous than in specimens of the other species 

 of Euborellia at hand. 



Length of body (exclusive of forceps) 16.9 and 17.8; greatest 

 width of head, 2.6 and 2.8; length of pronotum, 2.7 and 2.7; cephalic 

 width of pronotum, 2.3 and 2.6; caudal width of pronotum, 2.7 and 

 3; length of forceps, laterally 3.3 and 3.7, dorsally 2.8 and 3 mm. 



For the type female the total length is given as 23, the length of 

 the forceps as 3 nun.

St. Jean du Maroni, French Guiana, V, 1 9 . 



Length of body 10, length of pronotum 1.3, length of tegnien 

 2.2, length of exposed portion of wing 1.6, length of forceps 1.7 mm. 



This specimen has fully developed tegmina and wings, but agrees 

 so closely with material in the Philadelphia Collections which we 

 believe to represent this species, showing a varied development of 

 the organs of flight, that we make the present assignment feeling 

 assured that we here have to deal with a species which develops a 

 remarkably wide range of tegminal and wing variation. 



The present specimen agrees closely Avith a female from Porto 

 Velho, Rio Madera, Brazil except that in that specimen the teg- 

 mina and exposed portions of the wings are not as elongate. Both 

 of these specimens have the femora more generally and not as con- 

 trastingly darkened as the specimens having short tegmina and no
