Macrocentridae. 



/ Leptozele^ gen. nov. 



Radius long, issuing from the base of the apical fourth of 

 the stigma, its basal abscissa not half the length of the 2"^^ 

 Transverse basal nervure interstitial ; the recurrent nervure 

 received shortly beyond the middle of the V^ cubital cellule, 

 the basal (and longer) abscissa of the cubitus obliquely sloped 

 downwards ; the 2'"^ cubital cellule narrowed towards the apex, 

 much longer behind than in front, through the transverse 

 cubital nervure being obliquely sloped. Anal nervure not inter- 

 stitial, but issuing from half way between the middle and 

 apex of the nervure. Abdomen flat above, slightly widened 

 towards the apex ; the l'^^ segment as long as the following 

 2 united ; the ovipositor as long as the body. Mesonotum 

 trilobate, the middle lobe raised. Eyes large, occupying the 

 whole outerpart of the head, the temples and malar space being 

 very small, ('lypeus convex, clearly separated. Palpi long, the 

 joints long, pilose ; the 3'"'^ almost as long as the S""'^ anten- 

 nal joint. Mandibles short, broad above and with 3 blunt 

 lobes below the apex, ending in a small, sharp tooth. The 

 antennœ are incomplete, so it is impossible for me to give 

 the number of joints. Spurs not much more than one fourth 

 of the length of the metatarsus. Occiput not margined. Abdo- 

 men laterally compressed towards the apex ; its hypopygium 

 large. The 2"'^ discoidal cellule is closed below, not open as 

 in Zd(\ 



This genus may be separated from Zele by the non-mar- 

 gined occiput, by the more prominently 3-lobed mesonotum, 

 by the long, slender abdomen with long ovipositor, and by 

 the recurrent nervure bein^ received nearer the middle than 

 the apex of the cellule ; from Macrocentriis by the 1^* abdo- 

 minal segment being as long as the following 2 united, while
