joints; the flagellar joints are longer than thick, the last twice as long 

 as thick, pnbescent. Legs rufons, th(> femora and tibife, at the mid- 

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



Habitat. — Florida. 



Type $ in Coll. Ashmead. 



LiELIUS Ashmead gen. nov. 

 (Type L. irogodermatis.) 



Head oblong, nearly as wide across the eyes as long; in $ wider 

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

 and larger in the $ than in the $ . 



Antenna^ 13-jointed, tiliform, more than twice as long as the head in 

 the female, and in the male mncli longer; the scape is about one-third 

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

 stouter than the llagellum; the jjedicel in the 9 is a little longer and 

 stouter than the first flagellar joint, in the $ slightly shorter; the 

 second flagellar joint slightlj^ shorter than the first. 



Maxillary palpi 4-jointed ; labial palpi o-jointed. 



Mandibles curved, broadened, 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 quadrate, aibruptly 

 truncate behind, finely transversely rugulose, usually with 3 delicate 

 longitudinal carime. 



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 s*egment 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, 2, the tarsi longer than 

 the tibise, slender, claws simple. 



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

 tennfe and the difference in the palpi readily separate the two ; while 

 from Ateleopterus, which also has 13-jointed antenufe, 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: 



Coxse and femora, except tips, lilack. 



Wings hyaline L. trogodermatis, sji. nov. 



Legs rufous or reddish-yellow. 



Anterior cox;c black, the others usually dusky. 



Metathorax with 3 carinpe on disk L. tricarinatits, ap. nov. 



All cox IP pale. 



Metathorax with 4 carina" on disk, transversely rugulose. .L. ri'fipes, sp. nov. 

 Metathorax with 1 carina on disk, finely punctulate..L. nigripilosus, sp. nov.
