Genus NIRVANA. 



Nirvana, Kirk. Entomoloqist, xxxiii, p. 293 (1900) ; Melich. Horn 

 Faun. Ceylon, p. 1G5 (1903). 



Type, N. pseudommatos, Kirk. 



Distribution. British India. 



" Head porrect, plane, nearly twice as long as prouotum ; the 

 lateral margins parallel so far as ocelli, subsequently very gently 

 convergent, apex subangular ; eyes longer than wide, produced 

 basally over the anterior margin of the pronotum, which is some- 

 what wider than the base of the vertex ; ocelli small, indistinct, 

 situated on the lateral margins of the vertex, at about half their 

 length from the base; posterior margin of head concave; frons 

 slightly concave ; antennte simple, very long ; scutellum slightly 

 shorter than pronotum ; anterior coxae free." {Kirlcaldy.) 



In the above generic indication Kirkaldy has made no mention 

 of the tegmina which have three or four apical cells bounded by 

 three longitudinal veins. Melichar has described the genus more 

 fully, but his artist in figuring two species (Hom. Faun. Ceylon, 

 t. V, figs. 4 & 5) has omitted the spinules to the posterior tibiae, 

 which might lead to the supposition that the}' belonged to another 

 family. Sometimes the veins are very delicate and indistinct as 

 shown in the figure of N. linealis (p. 28:2). 



Kirkaldy originally placed this genus in the Acocephalous 

 Jassinae. He has since suggested it may belong to the Typhlo- 

 cybinae.
