to a simple straight vein. More commonly, however, it gives 

 off a vaulted and forwardly directed branch. 



The family is described from the wings, the body being 

 unknown. 



Lepium elongatum, gen. et sp. n. Text figure No. 8. 



The wings of the insects of this genus are elongate with 

 rounded apex and narrowed base. The radial sector is given 

 off not far from the termination of the basal third of the wing,, 

 and in the type species is two branched. Media is free. It 

 divides early, M, being deeply forked. Near the termination 

 of M 2 the areoles pass into accessory veins, of which there are 

 four. From Cu, several (about eight) inferior veins pass to the 

 border. The anal area is traversed by two simple veins. 



Length of front wing, 12 mm ; width, 4 mm . Type, No. 132. 



Lepium reticulatum sp. n. 



This species is described from one complete front wing with 

 which is associated parts of the hind wing. Radius reaches 

 farther along the costal border toward the apex than does the 

 radius of L. elongatum,. The sector is three instead of two 

 branched, one branch being lost, however, in the areoles of the 

 wing, and not reaching the border. Media is similar to that of 

 the type species, as are also the cubital and anal areas. 



The anal area of the hind wing is expanded, thin, and plicated. 

 Areoles in this part of the wing are lacking. Of the remainder 

 of the hind wing the apical and inner parts only are preserved. 

 This part of the hind wing is of a texture similar to that of the 

 front wing. 



Length of front wing, 13 mm ; width, 4 ram . Type, No. 152. 



Lepium ? sp. 



A detached hind wing, contained in the collection, probably 

 belongs with Lepium or with a closely related genus. The 

 middle two-thirds of the wing is preserved, the extreme base 

 as well as the apex being wanting. The sector divides tardily r 

 resembling in this respect L. elongatum. Media is but two 

 branched. Cubitus is a deeply impressed vein running from 

 the base to the inner border. This vein gives off beyond the 

 middle a thin, vaulted, forwardly directed, two branched 

 division. The anal area is seen beneath and in front of the 

 wing. It is thin, traversed by parallel veins, and lacks areola- 

 tion. 



Width at the termination of the anal area, 4 mm . Width across 

 the anal area probably not less than 4J to 5 mm . Length esti- 

 mated, 11 to 12 mm . type, No. 319.
