white, the antennae rufo-testaceous, the apical joints much paler than the others; wings 

 hyaline, the stigma, nervures and horny points deep black; of the latter there are 3 black 

 ones and a small testaceous one between the anterior pair ; the large basai one is broad and 

 transverse behind, where it broadly projects at the base, the apex is broadly roundly curved 

 inwardly; the lower point is a curved line, more sharply pointed at the apex than at the 

 base ; the upper apical one is wider and a little larger, it runs from the cubitus, is broad in front, 

 narrowed towards the apex; the transverse cubital nervure is one third of the length of the 

 apical abscissa of the disco-cubital and more than half the length of the récurrent. Legs 

 pallid rufo-testaceous, the hind coxae and femora black. Thorax densely covered with white 

 pubescence, hiding almost the sculpture ; the mesopleurae closely longitudinally striated, finely 

 so above, where they are more shining; the metapleurae more strongly striated; the metanotum 

 behind the keel closely reticulated. Q. 



Length 14 m. m. 



The stemmaticum is black and there is a black line down the middle of the front. 



This species is easily separated by the black large horny alar points and by the white 

 abdominal band. 



5. Enicospilus caenospiliis sp. n. 

 Bivak Island, January. 



Rufo-testaceous, the fiagellum of antennae, stemmaticum, the apex of the 4't and the 

 whole of the following abdominal segments, black, the antennal scape rufous, black above; 

 wings hyaline, the nervures and stigma black; the basai half of the first abscissa of the 

 radius roundly dilated, the horny point small, narrow, about twice longer than wide, of almost 

 equal width, the top rounded and slightly wider than the lower part. The basai latéral part 

 of the metanotum has an obliquely striated belt; the rest is more strongly transversely striated, 

 the sides more finely than the middle. Mesopleurae finely closely longitudinally striated. Q. 



Length 12 m. m. 



This species differs from the others in the rod-like horny point: in the others it is 

 more or less triangular, or at least it is broadly dilated in front.

Mesostenini. 



The species formerly included in Mesostenns with the metathorax armed behind with 

 spines on the sides hâve been separated by Ashmead into a distinct genus Mesostenoideus. 

 The séparation is a useful one, although it must be said that in some species the spines are 

 only small tubercles. It may be useful to refer the New Guinea species described under 

 Mesostenus by Smith, Brullé and Tosquinet to their respective gênera as now limited. To
