 passing the base of abdomen.

Other specimens from the same locality in the collection of 

 Dr. Signoret, which I have since examined, are somewhat darker in 

 hue, especially the anterior legs, which are brownish. 



Montrouzier's description is so slight that I certainly should have 

 failed to identify his species had I not received specimens so labelled 

 from Dr. Signoret. I have therefore given a full description of this 

 insect, which I have placed provisionally in the genus Tibicen. From 

 this, however, it somewhat differs in the ulnar veins at base, which, 

 though distinctly separated, are yet contiguous, thus approaching 

 the genus Melampsalta. 



Melampsalta oldfieldi, n. sp. 



2 • Head, pronotum, and mesonotum greenish ; abdomen green- 

 ish ochraceous, a central longitudinal castaneous fascia extending 

 from base of head to apex of abdomen. Head with four large black 

 spots on vertex, two at area of ocelli, and two in front of eyes ; 

 mesonotum with pale ochraceous margins to the central castaneous 

 fascia ; central base of abdominal margins blackish. Body beneath 

 pale greenish ochraceous ; face castaneous with its whole central 

 disk black. Tegmina and wings pale hyaline ; tegmina with the 

 costal membrane and basal venation greenish, remaining venation 

 pale fuscous ; claval area and that between the postcostal vein and 

 the postcostal ulnar ramus warm ochraceous. 



Wings with the base ochraceous, the claval area more or less 

 suffused with the same colour, the veins greenish, becoming fuscous 

 towards outer margin. 



The anal sheaths enclosing ovipositor are fuscous, and project 

 considerably beyond the apex of the abdomen ; the ovipositor is dark 

 castaneous, the last abdominal segment being triangularly excavated 

 at its emergence ; the rostrum just passes the intermediate coxse, and 

 has its apex castaneous ; the face is laterally compressed and concave 

 on each side, the central sulcation being very deep. 



Long. 21 milHm. ; exp. tegm. 55 millim.

The broad central castaneous fascia on the upperside of the body 

 of this species renders it very distinct from the other numerous 

 Australian species of the genus.

c? . Body and legs dull ochraceous and sparingly pilose. Head 

 above strongly hirsute, with the area of the ocelli infuscated. Pro- 

 notum with a short basal longitudinal castaneous spot. Mesonotum 

 with two obconical black-margined spots at a\iterior margin, on basal 

 sides of which are two small black marginal spots, a castaneous 

 transverse spot in front of the cruciform elevation, on each side of 

 which is a subquadrate black spot. Beneath, the abdomen is rather
