NORTH AMERICAN PSYLLID^. 79 



hind margin of the head, deeply impressed behind and becoming obsolete before 

 reaching the anterior margin of vertex ; basal joints of antennae larger and wider 

 than usual and reddish; joint 2 narrower and shorter than I, joints 3-6 and the 

 bases of 7 and 8 pale yellow, remaining joints black ; joint 3, of the form described 

 above, longer than joints 4 and 5 together; joints 6, 7, and 8 each a little longer 

 than joint 4; 9 and 10 of usual shape, closely connate ; terminal bristles long. 

 Pronotum colored as the head, of nearly equal width, laterally less convex than 

 usual, nearly horizontal longitudinally, moderately long, indentation at middle of 

 hind margin acutely triangular ; dorsulum with very faint traces of paler longi 

 tudinal markings, very little higher than the pronotum. Mesonotum nearly as 

 long as the dorsulum, with two broad pale median bands, separated by a fine 

 subimpressed dark-colored median line, sublateral yellow lines barely indicated. 

 Front wings, of the form described above, colorless, except a slight brown shade 

 alongside the marginal venules ; veins fine, yellowish-brown ; third furcal one- 

 third shorter than the fourth, and nearly rectangular upon the margin, second fur 

 cal about one-third longer than the fourth, strongly arched, first furcal slightly 

 shorter than the third, terminating obliquely upon the margin ; outer basal cell 

 much narrower than the inner and as long as the radial cell; inner basal cell at 

 taining the middle of the margin, marginal cells unlike in form but about equal 

 in size. The anterior legs, especially the femora, are much longer than the mid 

 dle legs ; the anterior femora are, moreover, much wider, flattened, and bent in 

 wardly at middle, or rather sinuate at the inner broad side.* The hind legs are 

 nearly as long as the anterior, but the femora are of normal form. Metasternal 

 processes rather widely separated, conical, acuminate. 



The genital armature of the male cannot properly be described 

 from the two specimens before me. 



Described from two 6*s, found March nth, 1879, at Baldwin, 

 Fla., by Mr. E. A. Schwarz, to whom I take pleasure in dedicating 

 the species, on low plants in the cypress swamps, but the food-plant 

 of the species still remains unknown. 



*This curving of the anterior femora is not equal in the two males before me, 

 being very conspicuous in the one and less so in the other.
