FAM. CICADIDiE 57 



pronotum about as long as head, its lateral margins armed with a distinct medial spine; mesonotum 

 moderately tumid; abdomen considerably longer than space between apex of head and base of cruciform 

 elevation: tympana covered, tympanal coverings broader than long; opercula short, just reaching basal 

 abdominal segment, laterally oblique and thus exposing the marginal areas of the cavities ; rostrum 

 reaching the posterior coxae; anterior femora strongly spined beneath; tegmina and wings hyaline, the 

 first considerabh' longer than the body and with its greatest breadth considerably less than a third of its 

 length; apical areas eight; basal cell longer than broad.

Division LAHUGADARIA 



Lahugadaria. Distant.. Ann. Mag. Nat. Hist. (7), Vol- i5, p. 304 (igo5). 



Characters. — This division is primarily divergent from Dundubiaria by the non-dentate lateral 

 margins of the pronotum ; the tympana are completely covered, the tympanal flaps broader than long; 

 the opercula short, somewhat globose, wider than abdominal margin, and distinctly visible from 

 above. 



50. Genus LAHUGADA, Distant 



Lahugada. Distant, Ann. Mag. Nat. Hist. (7), Vol. i5, p. 304 (igo5). 



Characters. — Head (including eyes) considerably narrower than base of mesonotum, its 

 length about equal to space between eyes, its lateral margins discontinuous, the lateral margins of front 

 being almost at right angles to those of vertex; pronotum almost as long as mesonotum, narrowed 

 anteriorly, the posterior angles prominent and rounded; abdomen considerably longer than space 

 between apex of front and base of cruciform elevation; tympana completely covered, tympanal cove- 

 rings broader than long; opercula short, somewhat globose, wider than abdominal margin, and 

 distinctly visible from above; rostrum about reaching the posterior coxa;; tegmina and wings hyaline, 

 the first with eight apical areas and the basal cell longer than broad.

1) Champaka harveyi. nov. spec. — c?. Body above dack castaneous; eyes posterior and lateral margins of pronotum, and the cruci- 

 form elevation ochraceous; body beneath paler castaneous very thickly, shortly greyishly pilose ; legs more or less dark castaneous, the tarsi ochraceous; 

 rostrum ochraceous; opercula dull ochraceous; tegmina and wings hyaline, the venation of both and the costal and post-costal membranes and basal cell 

 of the first brownish-ochraceous or piceous ; head (including eyes) considerably broader than base of mesonotum, its length about equal to breadth 

 between eyes; pronotum about as long as head, its lateral margins armed wish a distinct medial spine; abdomen considerably longer than space between 

 apex of head and base of cruciform elevation; tympanal coverings broader than long; opercula short, just reaching basal abdominal segment, laterally 

 oblique, apices subacute; rostrum reaching the posterior coxje; anterior femora strongly spined beneath.

Differing from C viridimaculata, Dist. the only other described species of the genus by the non-infuscated basal veins to the apical areas of 

 the tegmina, and the absence of the greenish basal markings to both tegmina and wings ; the apices of the opercula are also distinctly subacute.
