HYMENOPTERA FROM SARAWAK. 31 



stigma and nervures black ; the second transverse cubital 

 nervure is obsolete ; as is also the cubitus from the first trans- 

 verse cubital nervure, which is interstitial with the recurrent. 



The radial cellule is wide at the apex, through the radius 

 having an oblique downward slope at the base ; the apical 

 abscissa is straight and oblique ; the transverse basal nervure is 

 almost interstitial. Legs black ; the calcaria fuscous ; the tibire 

 without spines. 



The metastemal forks are roundly curved. In Schlettere's 

 Monograph (Ann. K. K. H. of Mus. Wien. 1889) this species 

 would come near E. appendigaster Linn. 



Megiseleus longicollis, sp. nov. 



Black, the head yellowish-red; the four front legs tinged 

 with rufous ; the wings clear hyaline, the cubital and the 

 transverse cubital nervures obliterated ; the radius incomplete, ? . 



Long : 18 ; terebra 17-18 mm. 



Hab. Sarawak, Borneo (Shelford). 



Antennae black ; the basal three joints rufous. Head pale 

 rufous, the orbits with a yellowish tinge ; the anterior three 

 tubercles are longer and sharper than the posterior ; the front 

 is coarsely, closely striated, obliquely above, transversely below ; 

 the vertex, behind the ocelli, is indistinctly furrowed in the 

 middle, and closely obliquely striated on either side of it ; the 

 outer orbits are smooth. The prothorax has a brownish tinge ; 

 it is distinctly longer than the mesothorax, is deeply and widely 

 incised at the base, the apex of the incision being rounded ; the 

 basal half is closely transversely striated, the apex is indistinctly 

 striated ; the dilated apex is smooth. Mesonotum coarsely, 

 irregularly reticulated at the base; the apex is widely depressed 

 in the middle, the raised sides are irregularly punctured. Scutel- 

 lum smooth, its sides punctured. Mesopleurae smooth ; the base 

 pilose. Median segment closely and regularly reticulated. 

 The propleume in front of the tegulre are strongly striated. 

 The hinder coxre are closely, but not strongly, striated ; the coxal 

 teeth are irregular and not very prominent. Wings clear 

 hyaline ; the nervures and stigma black ; the basal abscissa of the 

 radius is straight and oblique and forms an angle with the apical 

 branch which is about equal in length to it ; only the basal two
