1^^17] Insects in Burmese Amber 329 



ISOPTERA. 

 Hodotermes tristis sp. n. 

 Wing about 4.3 mm. long, dusky grey, the veins distinct. Radius 

 thick (appearing as two fine parallel lines), very close to costa, giving off 

 an uncertain number of delicate branches above; media apparently 

 simple (apex of wing not visible), about midway between radius and 

 cubitus; cubitus with five oblique branches below, the first two soon 

 bifurcating. There is apparently no subcosta. 



Burmese amber, from R. C. J. Swinhoe; in a slab cut from 

 the same lump as that containing the type of Acmaeodera 

 burmitina, and with the apex of the wing reaching the edge of 

 the slab, where it is 4 mm. thick, about 3 mm. from a broken 

 ferrugious blattid tegmen and 8 mm. from an elaterid beetle. 

 I at first thought this might be a Termes, as the superior branches 

 of the radius are delicate and indistinct, but they are certainly 

 present. The remoteness of the media from the radius readily 

 distinguishes it from Calotermes. The group Termitinse doubt- 

 less arose through the approximation of the radius to the costa 

 and consequent loss of branches; so the present insect may be 

 considered to represent a development in that direction. 



HOMOPTERA. 

 Liburnia (s. lat.j burmitina sp. n. 

 Length of body about 4.2 mm., to tip of closed elytra probably 

 about 5.7 mm.; dark brown; elytra pale testaceous, without markings; 

 vertex obtuse; frons with very distinct lateral carinas; tibial spurs very 

 short, about equal Con hind tibia) to width of tibia at apex; apical 

 margm of tibia finely dentate; tarsal joints with apical margins pro- 

 vided with numerous minute straight blunt spines; eyes pyriform, 

 scarcely emarginate below. Venation as shown in Figures. Scutellum 

 not visible. 



Burmese amber, from R. C. J. vSwinhoe; in a slab cut from 

 the same lump as that containing the type of Acmaeodera 

 burmitina, 13 mm. from the margin. The slab is the one 

 having one side rough. Very close to the Liburnia is a specimen 

 of Burmitempis halteralis Ckll., from which I have made a new 

 figure. 



This insect is evidently not a Liburnia in the restricted 

 sense. It appears to fall in the vicinity of Copicerus, but it has 

 the more primitive, separate anal veins. It should possibly 

 be regarded as the type of an extinct genus, but if so, the, 

 separation should be made by one more familiar with Delphacine 

 genera.
