than long, posterior ocelli much nearer to each other than to the 

 eyes, and the bosses are much nearer to posterior ocelli than to the 

 eyes; the anterior bosses are elongate, oblique, and together form 

 a V. Setae short, the joints for some distance out are broader than 

 long. Pronotum much broader in front than l)ehind, anterior 

 corners sharp, posterior corners rounded, sides much rugose. In 

 fore wings there are four cross- veins beyond the end of the subcosta; 

 eight or nine costal cross-veins; radial sector with four branches; 

 about seven median and five cubital cross-veins. Expanse 32 mm. 

 From Clayton, Ga., 2,000 to 3,000 feet, June (Davis). 



Perla xenocia n. sp. PI. XXVIII, figs. 5, 12. 



Head yellow, a large dark brown spot over the ocelli, pointed 

 behind, truncate in front; antennae and palpi black, pronotum dull 

 black, anterior lobe of mesonotum, and two spots on the metanotum 

 black; abdomen pale yellow; setae black; legs black, femora (except 

 tips) pale yellow; sternum yellow. Wings dark brown, veins dark, 

 except the yellow costa. Posterior ocelli fully three diameters apart, 

 a little further from the anterior ocellus, and not one diameter from 

 the lateral bosses, latter about their length from the eyes. Pro- 

 notum about one and one-fifth broader than long, barely narrowed 

 behind, the corners nearly square, surface rugose. Wings rather 

 long, about 17 costals, not far apart, three or four cross-veins beyond 

 end of subcosta, three branches of the radial sector, and a minute 

 apical fork, about 7 or 8 median and cubital cross-veins, in hind 

 wangs 8 or 9 cubital cross-veins, and the anal fork has three branches; 

 in both wings the radial cross-vein is oblique. Last joint of the 

 maxillary palpi about twice as long as the preceding joint; the third 

 nearly twice as long as the fourth; last ta,rsal joint twice as long as 

 others together. Expanse 42-45 mm. 



From Singla, Darjiling, India, 1,500 feet, April (type in Indian

Neoperla phantoma n. sp. 



Body pale yellowish; margin of pronotum faintly brown, palpi 

 dark brown or black, antennae slightly brown, basal part pale; 

 black mark above on tip of femur, and on tip of last tarsal joint. 

 Wings faintly brownish, veins (except costal) brown, hind wings 

 all pale, except brown radial cross-vein. Ocelli not diameter apart, 

 about twice as far from the eyes, ocelli very close to the bosses, 

 latter scarcely their length from the eyes; third joint of maxillary 

 palpi barely longer than the fourth; last tarsal joint hardly twice
