On the Genera of Hapalidas. 2-47 



A smaller and less robust species than the last^ but 

 agreeing with it in the absence of apical abdominal spines.

Phanerotoma nova-guineensis, Szep. Termes. Fiizetek, xxiii. p. 59 

 (1900). $. 



A single specimen from Mackaj, Queensland, taken in 

 August 1900, answers well to the briet' description of this 

 species. 



Phanerotoma leeuwinensis, sp. n. 



cJ . Brunneo-ochraceiis ; mesonoto lateribus, mesopleuris, segmento 

 mediano, segnienfcisque dorsalibus lateribus nigris ; segmento 

 dorsali tertio fiisco, peclibus pallide testaceis ; tibiis posticis basi 

 albidis apice pallide bruuneis ; alls hyalitiis, venis fuscis. 



Long. 2'o mm. 



(^ . Antennae 23-jointed, a little longer than the insect ; 

 the whole surface finely granulate, clothed on the head and 

 thorax with very short and delicate white pubescence ; 

 sutures between the tergites finely crenulated, the third 

 tergite distinctly longer than the second. Recurrent nervure 

 interstitial with the first transverse cubital nervure ; first 

 abscissa of tlie radius as long as the second, but distinctly 

 shorter than the second transverse cubital nervure. Meiian 

 segment without a carina. Posterior ocelli a little further 

 from the hind margin of the head than from each other. 



Hab. S.W. Australia, Tallingup {Turner), November 

 1913. 



Easily distinguished from nova-gumeensis by the very 

 different shape of the second cubital cell ; in that species, as 

 in most of the species of the genus, the second abscissa of the 

 radius is much longer than the second transverse cubital 

 nervure. The colour is probably variable as to the extent of 

 the dark markings. 



XXVII. — The G^ewera o/ Hapalidse {Marmozets). 

 By R. I. PococK, F.R.S. 



Introduction. 



Many attempts have been made in the past to classify the 

 marmozets generically, notably by Wagner, Lesson, Reichen- 

 bach, and Gray ; but the distinctive characters employed 

 have appealed so little to the judgment of modern zoologists
