Black : antennae straw-coloured at the base, dusky at the apex, and the basal 

 joint with occasionally a black dot above ; abdomen of the male with a pale 

 ochreous band at the anterior margin of the 2nd and 3rd segments, of the 

 female with a broad ochreous stripe down the back of the 2nd, 3rd, and 4th

Genus XLII.— BRACHYPTERUS, Gravenhorst. 



Antennce filiform, curved, short, rather stout, about half the length of the 

 body : head shortish, a little narrowed towards the neck, the face somewhat 

 protuberant : eves ovate : thorax cylindric-gibbous : scutellum slightly con- 

 vex, and somewhat triangular, with the apex obtuse: abdomen oblong- 

 ovate, rather broader than the thorax, the basal segment thrice as wide as 

 the peduncle; ovipositor scarcely exserted: wings narrow, rather longer 

 than the thorax ; cellule wanting : legs moderate, femora slightly thickened^ 

 This singular genus may be instantly recognized by the brevity of 



its wings, combined with the form of its abdomen, and the shortness 



and stoutness of its legs.
