joints; the liatjellar joints are lonj;**!- than thick, the hist twice as long 

 as thick, i)nl)escent. Legs rufons, the femora and tibiee, at the mid- 

 dle, piceous. Wings subfuscous, with only an open costal cell, 



Hauitat. — Fh)rida. 



Type S in Coll. Ashniead. 



LiBLinS Asbmrad Ken. nov. 

 (Type L. trogodermatia.) 



Head oWong, nearly as wide across the eyes as long; in S wider 

 across the eyes than long; eyes large, oval, hairy; ocelli 3 in a triangle^ 

 and larger in the S than in the 9 . 



Antenna' 13-jointed, hlifonn, more than twice as long as the head in 

 the female, and in the male much hmger; the scape is about one-third 

 the length of the head, cylindrical, very slightly bent, and a little 

 stouter than the flagellum; the pedicel in the 9 is a little longer and 

 stouter than the first Hagellar joint, in the S slightly shorter; the 

 second flagellar joint slightly shorter than the first. 



Maxillary palpi 4-jointed ; labial palpi 3-joiuted. 



Mandibles curved, broailened, and truncate at tips, 5-dentate, the 

 outer tooth acute, followed by small teeth. 



Thorax elongate, the prothorax very long, triangular, rounded in 

 front; mesonotum very short, without furrows; scutellum with a trans- 

 verse impressed line at base; metathorax oblong ([uadrate, abruptly 

 truncate behind, finely transversely rugulose, usually with 3 delicate 

 longitudinal carinje. 



Front wings with two distinct basal cells, about equal in length, a 

 very short marginal and stigmal vein, and with the costal cell closed, 

 a vein running all along the outer margin. 



Abdomen subpetiolate, pointed ovate, the third segment the longest, 

 the fourth about half the length of the third, the following short. 



Legs moderate, pilose, the femora swollen, the anterior pair the 

 stoutest, the tibije subclavate, tibial spurs 1, 2, U, the tarsi longer than 

 the tibiae, slender, claws simple. - 



. In venation this genus resembles Bethylus, but the 13-jointed an- 

 tennae and the difterence in the })alpi readily separate the two; while 

 from Ateleopterus, which also has 13-joint«d antennje, it is at once dis- 

 tinguished by the two basal cells and the short but distinct stigmal 

 vein. 

 Three species are known to me, which may be separated as follows : 



Coxffi and femora, except tips, black. 



Wings hyaline L. trogodermatis, sp. nov. 



Legs rufous or reddish-yellow. 

 Anterior coxjb black, the others usually dusky. 



Metathorax with 3 carinse on disk L. tricarinatus, sp. nor. 



All coxte pale, 

 Metathorax with 4 carinte on disk, transversely rugulose. .L. rufifes, sp. nov. 

 Metathorax with 1 carina on disk, finely puuctulate . . L. migripilosus, sp. nor.
