(? . Body above ochraceous-brown ; head with the margin of the front and the vertex much suffused 

 with blackish. Pronotum with two central longitudinal fascia, which are most widely separated at anterior 

 margin ; on each side of disk is a curved linear spot, and a large, oblique, semi-oval, linear spot on each 

 lateral area, black. Mesonotum with five black fasciae ; the central fascia crossing disk and widened 

 anteriorly and posteriorly, one on each side of this short and curved, and one on each lateral area crossing 

 the whole of disk, and a spot in front of the anterior angles of basal cruciform elevation, black. Abdomen 

 with the segmental margins somewhat broadly black. Body beneath ochraceous ; head, excluding face, 

 blackish ; bases of tibiae, the tarsi, and basal segment of the abdomen, fuscous ; apical segment of the 

 abdomen somewhat infuscated. 



Tegmma and wings pale hyaline, the venation fuscous or ochraceous ; the first with the costal 

 membrane ochraceous. 



The face is moderately tumid and not centrally and longitudinally sulcated ; the rostrum reaches the 

 posterior coxae; the opercula are small, wide apart, and somewhat angulated. 



Long. excl. tegm. (? , 16 to 17 millim. Exp. tegm. 47 to 54 millim.

Stal* has SO clearly defined this genus, as above understood, that it is as well to use 

 his diagnosis. 



" Caput thoracis antico latitudinse sub^equale ; vertice ocuHs circiter duplo latiore ; fronte leviter vel 

 modice convexa, sulco longitudmali medio plus minus distincto instructa. Thorax postice quam antice 

 latior, marginibus lateralibus obtusis, raro paullo explanatis. Tegmina venis ulnaribus basi contiguis vel 

 basin versus in unam conjunctis, areis apicalibus octo, areola basali quadrangulari. Segmentum ventrale 

 ultimum feminarum apice profuudissime lateque emargiuatum. Tympana superne tota detecta. Opercula 

 parva vel mediocria. Femora antica subtus spinis tribus vel quattuor armata." 



A character by which Mdampsalta can be readily discriminated from the other genera of 

 Oriental Tibiceninae here enumerated, is found in the tegmina by the united bases of the ulnar 

 veins at the end of the basal cell. 



Melampsalta has probably a world-wide distribution, at least wherever the Cicadidae are 

 found ; but it reaches its maximum of representation in Australia and New Zealand, where it 

 is certainly the dominant genus. It is poorly represented in this fauna.
