as in Dorypteryx); head not very broad and the eyes not especially promi- 

 nent ; antennae filiform ; abdomen rather slender. 



Type, P. slossono'. 



This genus differs from Dorypteryx by the shape and vena- 

 tion of the wings ; from Psoquilla hy less prominent eyes, 

 venation and less swollen femora. Psoquilla is evidently its 

 nearest ally ; in that genus, however, the costal vein is not 

 forked, there are but two branches below from the median 

 vein, the anterior branch of the median is forked ; the head is 

 broad and ej'es very prominent ; and the abdomen is broad and 

 depressed. 



The three genera of Atropidse with veined wings may be 

 tabulated as follows : 



1. Wings broad, rounded at tip 2. 



Wings lanceolate, femora slender .... Dorypteryx. 



2. Costal vein forked, femora slender Psocinella. 



Costal vein simple, femora slightly dilated . . Psoquilla. 



Psocinella slossonae n. sp. 



Whitish, head yellowish, antennie purplish, a black spot above on the 

 fourth abdominal segment, tibise blackish. Wings hyaline, veins hyaline, 

 reaching beyond middle of abdomen ; the costal vein forked near tip ; the 

 median joined to the costal in two places near center of wing thus forming 

 a closed cell ; upper branch of median vein simple, three simple branches 

 below ; anal vein simple. Antennae filiform (broken beyond sixth joint). 

 Head not broad above, nasus prominent ; legs slender, basal joint of tarsus 

 about one-half as long as tibia ; hind tibia plainly longer than hind femora ; 

 abdomen slender, subcylindric. Body and legs sparsely clothed with fine 

 short hairs. 



I-ength, I.I mm. 



Descrilx*d from two specimens collected at Biscayne Bay, 

 Florida, by Mrs. A. T. Slo.s.son, to whom the species is dedi- 

 cated. 



Since this paper was written Dr. C. Ribaga has publishd the 

 description of a new genus and species* similar to the above. 

 His genus, Psocathropos, has the venation on the same plan, 

 but the veins are IkmU out of the straight course ob.served in 

 Psocinella. The thorax of his insect is much smaller than in 

 Psocinella. An imjK)rtant diflference is that Psocathropos has 

 very short hind femora, while in Psocinella they are a little 

 longer than the other pairs.
