hyaline, both narrowly testacco\is at their bases, venation 

 and eostal nicnil)ranc to tci^inina pale greenish. 



^. Head, pronotum, and niesonotiun olivaceous green; 

 area of the oeclli black ; carinations and a basal central spot 

 to front, lateral areas of vertex before eyes, an oblique space 

 on each side of pronotum between the fissures and behind 

 eyes, two ol)conical anterior spots, a central basal lanceolate 

 spot, a marginal basal spot, and a small spot at each anterior 

 angle of the basal cruciform elevation on mesonotura, pale 

 castaneous or piccous ; abdomen dull ochraccous; head 

 beneath, sternum, and legs pale greenish ; abdomen beneath 

 dull ochraccous ; tegmina and wings pale hyaline, both 

 narrowly testaceous red at base, costal membrane and 

 veins ot tegmina and wings pale greenish ; head (including 

 eyes) broader than base of mesonotum, front a little longer 

 than vertex, their margins not continuous, a short linear 

 central impression at base of front, a similar but broader 

 impression at base o£ vertex ; body above finely, irregularly, 

 palely pilose ; face beneath centrally piccous, the transverse 

 carinations pale castaneous ; basal and lateral margins and 

 apex of clypeus piccous ; rostrum reaching the intermediate 

 coxrc, its apex black.

Hub. Brazil; Espirito Santo (Brit. Mus.). 



Imbabura, gen. nov. 



$ . Head broader between the eyes than long, front sub- 

 angulate, lateral margins of the vertex distinctly lobately 

 semi-erect above the insertion of the antennae, eyes large, 

 longer than broad, projecting moderately beyond the ante- 

 rior pronotal angles ; pronotum subquadrate, subconvex, 

 about as long as mesonotum including the basal cruciform 

 elevation, which is transverse, a little broader than long ; 

 abdomen about as long as space between apex of head and 

 base of cruciform elevation ; rostrum about or almost reaching 

 the posterior coxae ; anterior femoi'a thickened, with about 

 three long spines beneath, tibiae spinulose ; tympana com- 

 pletely exposed ; tegmina elongate, about three times as 

 long as greatest breadth, eight apical areas, the upper two 

 short, the lowermost shortest, costal membrane and post- 

 costal area narrow ; wings short and narrow, about half the 

 length of the tegmina, apical areas four. 



Allied to Nelcyndana by the venation of the wings, which 

 have only four apical areas.
