TRAMEA CAROLINA (RaiBed.) 



I'i am VI. Kit;. -2. 



Three not full-grown nymphse in alcohol, from Charleston, South Carolina. Length, 



55 in in. 

 Similar to T. lacerata; groove behind vertex deeper; 3d joint of antennae short, little 

 than the twi igether; 4th joint two thirds of 3d ; movable hook long, with 



two long bristles; dorsal median appendage one fourth shorter than inferiors; laterals 

 shorter than dorsals, half the length of the inferiors; claws pale, darker at tip. 



A young bympha IS mm. long from Key West, Florida, January 7, 1878, from Mr. 

 Carman, is very similar to the foregoing ones; it differs perhaps by a little shorter lateral 

 Hid by a very interrupted black line on the tibia externally, which is almost con- 

 tinuous on the nymphse from South Carolina. 1 know from Key West only T. Carolina, 

 and the more common T. onusta, from Odenton, Md., raised by Mr. Uhler.

Hagen, Syn. X. A. Neur., p. 14.3. 



Four male nymphse, dry, and three male nympha skins, raised July 28 and August 4, 

 1S7<'>. in St. Louis, Missouri, by Mr. Ch. V. Riley, together with the imago. Length, 

 25 nun. ; breadth, 9 mm. 



Very much like Fantala flavescens ; head above flat, vertex transverse-ovoid, smaller ; 

 on each side an oblique shallow groove, with lateral dilatation on each side, forming broad 

 shallow grooves, in which the antenna? are inserted ; occiput rounded, not notched ; an- 

 tennae similar, longer, but 3d, 5th, and 6th equally long, 4th shorter. Mask a little more 

 prominent ; palpi thickly sprinkled with small blackish dots ; edge nearly straight, with 

 ten very short indentations, forming inside short black teeth with four spines, the lowest 

 largest, none visible when the palpi are closed, the edges interlocking perfectly ; movable 

 hook very long, reaching nearly the opposite margin of head, extending beyond the base 

 of the opposite antenna, pale with the basal half darker ; the movable hook of Fantala is 

 very short, little longer than the teeth of palpus. Wing cases reaching end of segment 7 ; 

 veins not so dark and well defined ; abdomen short, broad, rounded, on 4th segment longer 

 than broad, dorsum more roof-shaped, sides more flattened ; segments of equal length, but 

 10th only one fourth of 9th segment; lateral spines on 8th and 9th similar but longer; those 

 of 8th extending beyond the tip of 9th segment ; those of 9th as long as anal append- 

 ages, which are very similar to Fantala, except the dorsal median is a little shorter than 

 the inferiors, and the laterals less slender and very little shorter than the dorsal median ; 

 lateral spines and anal appendages larger and densely hairy except the lateral append- 

 ages, which are without any hairs; tip of segments with long and fine but widely sep- 

 arated hairs ; ventral longitudinal sutures more widely separated towards 3d segment, 

 sloping again to ba lis marked only on 3d -segment ; ventral bags large on
