476 MR. R. E. TURNER ON [May 12, 



the inner orbits of the eyes, with a longitudinal median sulcus ; 

 the anterior ocellus lying in a broad depression Avhich almost 

 reaches the eyes; on the vertex the eyes are separated by a 

 distance less than twice as great as the length of the first jonit 

 of the flagellum. The second joint of the flagellum is more than 

 twice as long as the first and nearly half as long again as the 

 third; the fourth and fifth joints about equal to the third. 

 Prono'tum depressed very much below the mesonotum, very 

 steeply sloped anteriorly ; mesonotum with a rather broad median 

 depression from the anterior margin to the middle. Median 

 segment a little longer than the mesonotum, nearly half as long 

 again as broad, obscurely transversely striated, the strife almost 

 obsolete at the apex, vertically truncate posteriorly, the face of 

 the truncation more strongly transversely striated, the sides 

 of the segment indistinctly striated. Abdomen subopaque, the 

 apical margins of the segments broadly depressed. Pygidial area 

 pubescent, with an obscure median carina, the lateral carin?e 

 strongly raised, separated at the apex by a distance not quite 

 equafto the length of the first joint of the flagellum. Anterior 

 tibi^ smooth, intermediate and posterior tibia? with a double row 

 of three or four widely separated and feeble spines ; tarsi spinose, 

 the ungues simple and very long. 



Black ; the antennae orange ; the pile on the head and abdomen 

 silvery, the abdominal segments with broad bands of pile on the 

 apical margin ; a pale golden sheen on the pile on the front and 

 a small patch of golden pubescence at the apex of the posterior 

 tibife. Wings fusco-hyaline, the apex of the anterior wings and 

 a broad band across beyond the middle fuscous, the apex of the 

 posterior wings broadly pale fuscous. Nervures black ; testaceous 

 at the apex of the radial and third cubital cells. 



The recurrent nervures are both received before the middle of 

 the second cubital cell, the distance between them not exceeding 

 one-sixth of the length of the cell on the cubital nervure. The 

 third cubital cell is about four times as long on the cubital as on 

 the radial nervure. 



Length 19 mm., exjD. 27 mm. 



Hah. Cairns, Queensland [Turner) ; December to March. 

 ' Mackay, Queensland ; October. Cape York, Queensland ; May. 



The specimen from Cape York has the wings fuscous from the 

 base, with a large hyaline patch near the apex of the anterior 

 wings ; the four apical joints of the flagellum are black and the 

 spines on the tibite stronger. 



The specimens from Mackay are smaller, measuring only 12- 

 14 mm., the strife on the median segment are almost entirely 

 absent, except on the face of the truncation, and there is a delicate 

 longitudinal cai^ina from the base almost reaching the apex. The 

 six apical joints of the flagellimi are black.
