Geni ■* TRAMEA. (Rai 

 Hager Syn. X. A. Neur . p. I 13. 



Nymphse very similar to Pantala; the palpus always sprinkled with line blackish dots ; 

 the teeth much shorter, interlocking in a. nearly straight line; movable hook very long, 

 and tine, more like a seta: joints of antennae specifically different, fourth always shorter 

 than third; median dorsal appendage shorter than the inferiors; laterals always with- 

 out spines; legs longer, thinner, densely fringed with long hairs, especially the tibia of 

 middle legs. 



The nymphse of all species very much alike, differing in the different length of joints, 

 of antennae, lateral spines, abdominal appendages, and legs. The eyes do not differ from 

 those of Pantala, as one might suppose they would, judging from the difference in the 

 eyes of the iniagos. 



Daring the transformation in the imago state the skin on the head splits along the 

 median line of occiput, and in an anterior curve on each side along the interior margin of 

 the eyes, both joined behind the vertex, meeting the median split of occiput. The anterior 

 curve never passes through the eyes. Pantala splits similarly. All Gomphina have the 

 eyes split transversely along the anterior curve.

 Hubbard. Length. 2o mm. 



Similar to T. lacerata ; head nearly destroyed; 4th joint of antenna two thirds the 

 length of third, in T. lacerata half as long; palpus finely sprinkled with black dots; teeth 

 more marked, movable hook yellow, a little shorter ; abdomen similar ; dorsal median 

 appendage more slender, one third shorter than inferiors, laterals as long as the dorsal; 

 legs similar, claws pale, no black above on middle third.
