61 Miss G. Ricardo on the 



Neoitamus gibbonsi, £ $ , sp. n. 



Type (male) in Brit. Mus. Coll., presented by C. Gibbons, 

 20. 2. 16, from Sydne 



Type (female) from Sydney, and other males and females 

 from the same place and by the same collector. 



This species will not, belong strictly to this genus, as the 

 ovipositor of the female, though long, does not include the 

 sixth or seventh segment ; but, as remarked by the late 

 Mr. Arthur White in his last paper, species from Australia 

 placed in this genus are many of them not typical and may 

 require later to be removed to a new genus peculiar to 

 Australia. 



It is a large species nearly allied to my Neoitamus hyali- 

 pennis, but distinguished from it by the ovipositor not in- 

 cluding the seventh segment, by the moustache being wholly 

 black, and the base of the hind femora more or less reddish 

 yellow. 



Length, <? 16-17, ? 18-24 mm. 



Male. — Face with a very large tubercle, blackish with pale 

 tomentum, thickest at the sides. Moustache composed of 

 many short black bristles. Palpi black, with white hairs. 

 Beard white. Antennae black, the first two j >ints and the 

 forehead with black bristly hairs. Thorax with the usual 

 stripes very distinct, the middle one not divided and the side 

 ones continued from the anterior border to the posterior 

 border ; the prsesutural, supraalar, and postalar bristles each 

 two in number ; dorso-central bristles numerous, some stent 

 and some hair-like, with short black hairs continued to anterior 

 border rather Dysmachus-Yike. Scutellum with at least two 

 stout black bristles, intermixed with finer hair-like ones 

 which also cover the dorsum. Abdomen blackish, with some 

 grey tomentum, and the segmentations grey ; sides grey ; 

 the pubescence on dorsum is thick and black, but short, sides 

 with white hairs. Genitalia long and narrow, longer than 

 the last two segments together, shining black, with short 

 black hairs. Legs black, the hind fe nora reddish at their 

 extreme base, in some of the specimens this colour is ex- 

 tended ; the tibiae reddish yellow for two-thirds of their 

 length; fore femora with long black and white hairs above 

 and below, the others with short black pubescence and black 

 bristles ; tibiae and tarsi with black bristles. Wings clear, 

 the small transverse vein almost in the middle of the discal 

 cell, which is very narrow. 



Female identical. The ovipositor, though not including
