Mr. F. Smith on some new species of Exotic Hymenopte^'a. 29 



stripe equal to one-third of its width down the centre ; the 

 orbit of the eyes yellow, inteiTupted at their vertex : two minute 

 yellow spots in front of the anterior stemma, and two very mi- 

 nute ones placed obliquely beyond them j the posterior pair of 

 stemmata are placed in a line with the vertex of the eyes; a 

 yellow line traverses the hinder margin of the vertex curving 

 inwards at a central interruption ; the mandibles are quadrate, 

 yellow, and tridentate, the apical tooth largest ; the teeth and 

 the extreme base ferruginous ; the antennae 19-jointed, the fii'st 

 joint at its base and apex and the seven following joints entirely 

 ferruginous ; thorax roughly punctured ; a line in front of the 

 tegulse, the tubercles, a minute spot beneath the wings, two in 

 front of the prothorax, two on each side of the scutellum and 

 one on each side of the postscutellum yellow ; the tegulse tes- 

 taceous, the nervures of the wings dark piceous; the anterior 

 margin has a fuscous cloud extending from the base to the apex, 

 where it is broadest; the legs ferruginous, their trochanters 

 yellow, the intermediate pair have a stain beneath ; the anterior 

 tibiae in front, and the intermediate and posterior pairs at their 

 base yellow; all the femora beneath are darkest towards their 

 base, the claws . black ; abdomen subpetiolate, incurved at the 

 apex, the second segment beneath has an obtuse tooth on its 

 apical margin. Above, the margins of the first, second and 

 fourth segments, and the whole of the fifth and sixth yellow ; 

 the two latter have an undefined black line down their centre ; 

 beneath, the first, second and third segments have their apical 

 margins yellow. 



Hab. Moreton Bay, New South Wales. 



I have only seen the single specimen in the British Museum ; 

 Mr. Westwood informed me he had also one. 



Genus Micropteryx, St. Farg. 



Pompilus, Fab. 



M. bicolor, n. sp. 



Female (length 10 lines) black : head shining, very minutely 

 punctured, the mandibles slightly ferruginous on their outer 

 margin ; the prothorax and a smooth triangular space on the 

 mesothorax ferruginous, as is also the scutellum, which is smooth, 

 shining, and very finely punctured ; the metathorax ferruginous 

 and rugose ; wings black, the length of the thorax ; legs and ab- 

 domen also black, the latter clothed with short black pubescence. 



This species resembles the brevipennis of Fabricius, but is 

 distinguished by its broader head, and by having the metathorax 

 entirely rugose, whereas in brevipennis it is finely crenulated 

 towards the base ; and the abdomen is spotless. 



Hab. Port Natal.
