PHYTOPHAGOUS AND PARASITIC HYMENOPTERA. 87 



reticulated ; the basal areae smooth at the base, the sides furrowed ; 

 the inner side finely, closely striated along the central keel ; the 

 apical slope irregularly rugosely striated. Propleurse strongly 

 obliquely, the upper part of the mesopleurse longitudinally striated ; 

 the lower part, near the base, finely, closely, slightly, obliquely 

 striated ; the apex rugosely punctured. Basal two-thirds of 

 mesosternum bordered by a deep furrow. Abdominal petiole 

 closely, strongly striated. Probrachial nervure in hind wings 

 interstitial ; the third abscissa of radius longer than the basal two 

 united. Face, except for a smooth shining line in the centre, 

 closely transversely striated ; the front closely striated, except at 

 the sides; the vertex and temples smooth and shining. Legs 

 sparsely haired ; the hind coxae striated on the outer side. 



Philomacroplosa, gen. nov. 

 Apex of sixth abdominal segment broadly, deeply, roundly 

 incised in the middle. First abdominal segment sessile, excavat- 

 ed at the base, keeled on the top ; it, and the second segment, keeled 

 down the middle ; the sutures of the segments narrow ; the 

 apical segments are curled downwards ; the abdomen short, broad 

 not unlike the abdomen of Chelonus. Metanotum smooth and 

 shining, stoutly keeled down the middle. Parapsidal furrows 

 distinct, deep, crenulated. Last joint of hind tarsi not much 

 dilated, as long as the second. Ovipositor short, broad. Antennae 

 longer than the body, the second joint of flagellum about twice 

 longer than thick. Malar space large, furrowed down the middle. 

 Third abscissa of radius about three or four times longer than the 

 basal two united. Temples obliquely narrowed. A broad furrow 

 behind the ocelli. 



The abdomen is more like what it is in the Chelonince than in the 

 Braconitice. It is allied to Tropidobracon, Baryproctus, and 

 Plesiobracofi, all of which have a stout keel in the centre of the 

 metanotum ; but, among other differences, the present genus 

 should be readily separated from them by the keeled base of the 

 first abdominal segment, by the first and second being keeled 

 down the centre ; by the last segment being roundly broadly 

 incised, and by the very long third abscissa of the radius. 



25. — Philomacrcyplcea basimacula, sp. nov. 



Head, thorax and the middle of the first and second abdominal 

 segments broadly rufo-testaceous, the mesosternum and the base 

 of metapleurae above blackish ; wings hyaline, the nervures and 

 stigma fuscous ; the legs pale testaceous, almost white, 9 and 6. 



Length 3*5 mm. 



Bred from Macroplaea elisa.
