A slender winged, ^-i-i-emis species, nt tar removed from I>. commo- 

 ratus. Tin- bodv, ho\\ever, is tolerably stout, den>elv clothed, tin- head 

 small, with very slender pale antenna-, tin- basal joint >t.mt and globular, 

 tin- Other joints slender, about twice a-; loii^- as broad, and narrowlv ringed 

 ajiicallv with fuscous. 'The le^-s arc ver\ \-<i\^ and delicate. the middle- and 

 hind tibia- with tun pairs of spurs. Front win^> ^riscmis, ratli.-r ln-a\-ilv 

 clothed with hairs, especially alon-- the veins, which are tlien-hv du.-kier; 

 tln-v are slender, \vell rounded at tin- ape\, and not ai-iiniinate. as would 

 appear from the tiunre, where the winir i> partialh' folded ; the neiiratiou is 

 imperfectlx shown in the plate. The first apical cell N very small, the third 

 a little lonyer than the fourth and much shorter than the second, which is 

 verv lonjr, nearlv reaching the middle of the win;:; the length of the di>- 

 coidal and median cells can not ho accurately determined. 



Length of hody, 6.75 mni ; of fore femora, 1.4 mm ; mid femora, -_'.-J mm ; 

 mid tihi;e, 2"""; hind femora, 3 mm ; hind tibiae, 2.75 mm ; front win^s, 7-8 mm ; 

 width of >ame, 2.75 mm .

A somewhat stout hodied hut small >pecies, the smallest of the LT'-nus, 

 not ver\ heavilv clothed with scales. The head is nioderateK lar^e and 

 the antenna' very slender, with a lar^e <_rl(il>o-e l,:i-al joint. The le^s are 

 onl\ preserved in a fragmentary way in all the specimens. The front \\ : 

 are toleraKly liroad, hroadest onl\ a little heyoiid the middle, the apex 

 scan-eU siiliaciiminate lint well rounded, the apical mar_rin oldiipie hut full ; 



the tirst apical fork is unusually straight with no up\\anl curve, arid the 



cell not much >horter than the third apical cell ; the second apical cell is 

 ahout t\\ ice as \,,\\^ aa the third, and the fourth tails about midway between 

 them in length ; the disroidal cell and the median are of about equal length 

 with the >econd apical cell, ami are verv .-lender, particularly the median 

 These features are not all produced in the plate.
