PIMPLINM. 



ACCENITINI. 



PAEACOLLYEIA, gen. nov. 



Fore wings without an areolet ; the transverse cubital nervure 

 short, the recurrent nervure is received beyond it. Transverse 

 median nervure received behind the transverse basal, almost 

 interstitial. Disco-cubital nervure broken by a stump of a nervure. 

 Transverse median nervure in hind wings broken distinctly above 

 the middle. Head cubital, the temples broad, the occiput transverse 

 or roundly incised. Antennae in 2 short, stout, the third joint 

 longer than the fourth ; in g longer, stout. Parapsidal furrows 

 deep. Median segment with only a semicircular area on the apex ; 

 the spiracles are placed in the middle ; they are large, linear. 

 Malar space long, not much shorter than the eyes, which are 

 parallel. Apex of clypeus transverse, or bluntly, broadly rounded ; 

 it is not separated from the face. Labrum hidden. Mandibles 

 edentate, curved, the apical half narrowed. First abdominal segment 

 stout, broad at the base, gradually widened towards the apex, 

 which is twice the width of the base ; it is as long as, or longer, 

 than the following two united ; the spiracles are placed shortly 

 behind the middle. Hypopygium cultriform, projecting. Second 

 abdominal segment wider than long. Legs stout ; the hinder greatly 

 lengthened ; much stouter than the anterior ; their basal joint is 

 slightly longer than the following two united. Four anterior claws 

 cleft ; the hinder long, curved, simple. 



The four species I have included in this genus are rather diverse 

 in colouration, but all have the characteristics enumerated above. 

 In Ashmead's table (Bull. U.S. Nat. Mus. xxiii. 48) it would enter 

 into Chorischizns, but it can hardly be referred to that genus. Its 

 nearest ally known to me is Siphimedia from the Oriental Zoological 

 Eegion. That genus may be known by the stoutly bidentate man- 

 dibles, areolated metanotum, by the apex of the clypeus not being 

 transverse, and by the transverse median nervure in hind wings 

 being broken in the middle, and by the interstitial recurrent nervure. 

 The species may be recognised by the following table : — 



a. Thorax and abdomen black. 



Wings fuscous with a hyaline cloud at the apex ; the disco- 

 cubital nervure broken by a stump of a nervure, head red, 

 antennae ringed with white ruficollis.
