The abdomen in the $ is broadly oval, in the 9 it is longer 

 (but still shorter than the thorax), and much more sharply pointed 

 at the apex; the ovipositor shortly projects. The femora and 

 tibiae are darker-coloured, more infuscated, in the $ than in the 

 ^. There is a broad, smooth keel on the apex of propleurse, and 

 a shorter, narrower one on the base of the mesopleurjt. The 

 second abdominal segment is slightly shorter than all the follow- 

 ing united, the third is about one-half its lengtli. Flagellum of 

 antennae densely pilose; antenu;e inserted opposite the end of the 

 eyes. 



I am not certain about the generic position of this species, 

 owing to my not being able to make out, with certainty, if the 

 eyes are pilose or bare. Tf pilose, the species might be referred 

 to Trichoylenes Thomas. 



APHKLIxN^^. 

 Aphelini. 



Marlattiella aleyrodesii, sp.n. 



Yellow, a broad stripe on vertex between and united to the 

 eyes, mesonotum and back of abdomen reddish-orange; wings 

 hyaline, nervures pale testaceous, basal nervure distinctly longer 

 than the marginal, narrower than it, and, if anything, darker- 

 coloured; the hair-fringe on the wings long. E3'^es large, black, 

 prominent, oval, if anything, a little longer than the malar space. 

 Antennal scape narrowed towards the apex, thinner than the 

 long apical joint, and a little shorter than it. 9. Length, 75-80 

 mm. 



Broken Hill, N.S.W.; 25th May; on Saltbush Aleyrodes. 



Smooth, bare and shining; legs of a paler yellow than the 

 antennae, which are as long as the body. The apical joints of the 

 antennae, viewed from the sides, are roundly narrowed towards 

 the l)ase and apex. The four anterior tarsi are not much shorter 

 than the tibiae: the hinder are clearly shorter; the tibife and tarsi 

 are .shortly, sparsely haired. 



The genus Ma7'lattieUa was described by Dr. L. O. Howard, 

 the well-known Chief of the Bureau of Entomology, U.S. Depart.
