242 P. CAMERON. HYMENOPTERA. 



i st abdominal segment one third longer than it is wide at the apex; the latéral furrows 

 gradually converge from the apex to the base where they unité into a short one; the 2 n<i is 

 a little wider at the apex than it is long; the others are wider than long. The area on the 

 2nd segment is clearly defined, is longer than it is wide at the base; the furrows do not 

 unité at the apex; there is a shallow, curved furrow on the outer side of the segment. The 

 ovipositor is as long as the abdomen. Q. 



Length 9 mm., terebra 3 mm. 



Face with a broad keel down its centre, its upper part sparsely, the lower more closely, 

 irregularly transversely striated. Mandibles red, tinged with yellow, black at the apex. 

 Palpi yellow. 



The 2 species described above are closely allied, but may readily be separated by the 

 undernoted points: 



The hind legs largely black; the ovipositor longer than the abdomen and metathorax; the 

 base of the radial cellule and the discoidal cellules not smoky, face with 2 keels down the centre 



maculipenne. 



The hind legs without black, the ovipositor as long as the abdomen, the base of the radial 

 and the discoidal cellules not smoky, face with one keel down the centre fasciatipenne. 



Doryctinae. 



Zombrus, Marsh. 

 1. Zombrus varicornis sp. n. 



Bivak Island, January. 



Testaceous, the thorax reddish, the base of the abdomen pallid yellow, the apical half 

 of the mandibles and the antennae black, the apical joints of the antennae yellowish; wings 

 fuscous, tinged with violaceous; the costa, stigma and the nervures black, the base of the 

 costa luteous, the tegulae coloured like the thorax ; the face sparsely covered with long pale 

 hair; the pro- and mesothorax bare; the metanotum and metapleurae thickly covered with 

 longish white pubescence; the apical segments of the abdomen sparsely covered with longish 

 fuscous hair. Legs somewhat thickly covered with long, erect white hair. The basai spine on 

 the hind coxae arises from close to the middle, is long and curved, rather erect, not steeply 

 oblique ; its apex does not reach to the end of the coxae, the 2 n d tooth is very small, oblique, 

 sharp-pointed at the apex, obliquely triangular as seen from the sides; the basai slope is the 

 longer. Face and clypeus rugose, more or less striated, the clypeus clearly separated, semi- 

 circular, the apex transverse. Front and vertex smooth and shining. Metanotum reticulated 

 irregularly, more widely at the apex than at the base; there is a fine keel down the middle 

 of the basai half, which has the reticulations somewhat stronger than the apex. Base of abdomen 

 closely, strongly longitudinal striated to the 2 nd furrow, the i st segment more strongly than 

 the rest. Apex of mesopleurae strongly crenulated ; the metapleurae strongly, but not very 

 closely punctured. The 2 nd cubital cellule twice longer than it is wide along the transverse 

 cubital nervures; the 2nd of the latter shorter than the i st , bullated on either side of the 

 middle; the y& abscissa of the radius oblique, slightly broadly roundly curved. Ovipositor 

 black, stout, fringed with black hair; as long as the abdomen. 9-
