and fifth also subequal ; pronotum about twice as broad at 

 base as length, lateral margins concavely sinuate, anterior 

 angles spinous, not quite reaching eyes, but extending 

 outwardly beyond them, posterior angles subprominent and 

 subspinous ; scutellum. coarsely punctate, a broad obscure 

 central ridge extending from apex to middle and then 

 bifurcating towards each basal augle, corium thickly punc- 

 tate ; rostrum ochraceous and reaching the posterior coxae. 



Long. 7\ mm. 



Hab. Queensland ; Peak Downs. 



Mycoolona, gen. nov. 



Head about as long medially as breadth at base between 

 eyes, moderately flattened, the lateral lobes a little longer 

 than the central lobe, but not converging beyond it, their 

 lateral and apical margins reflexed, the latter sinuate ; eyes 

 prominent; ocelli near base of head, scarcely nearer eyes 

 than to each other ; antennae of five joints, first not reaching 

 apex of head, second and third joints almost subequal in 

 length, each slightly shorter than fourth or fifth, which are 

 also subequal in length j pronotum about half as long as 

 breadth between pronotal angles, the lateral margins slightly 

 reflexed, the posterior angles subprominent; scutellum 

 longer than broad, a distinct black impression, longer than 

 broad, in each basal angle ; corium a little shorter than 

 pronotum and scutellum together; membrane not passing 

 abdominal apex ; rostrum with the first joiut not extending 

 behind the bucculae, its apex about reaching the posterior 

 coxae; odoriferous aperture continued in a long slender 

 groove. 



Type, M. atricomis, Westw. 



The position of this genus is apparently near that of 

 Anaxarchus, Stal.

 Westwood) . 



Two specimens of this species received from Tasmania 

 now afford an opportunity for generic location, the type not 

 being in a sufficiently perfect condition, for that purpose 

 when I examined and figured it in 1900.
