(Figs. 33, 34, 51, 55 and 85.) 



9. — Red; apex of tlie petiole iind the four anterior legs yellowish ; posterior 

 tarsi brown ; abdomen and antennae beyond the fifth segment black. Head seen 

 from above transverse, rounded in front and truncate behind ; the eyes very 

 large, reaching far up on the vertex and to the posterior margin ; ocelli large, in 

 an equilateral triangle, the posterior ones about their diameter's length apart, a 

 little less removed from the compound eyes. In profile little is visible except 

 the compound eyes; the malar space moderately long, the temples obsolete 

 above, widened below ; the antennse are inserted below the middle of the eyes. 

 From in front the head is slightly triangular, the margins of the eyes diverging 

 below; the face has no median tubercle, is moderately closely punctate; the 

 forehead more closely ; the temples and cheeks smooth and polished with only a 

 few small punctures; antennse shown in Fig. 55. 



Humeral angles rounded ; the mesonotum smooth and polished, with several 

 moderate sized punctures scattered over it, these a little thicker on the scutellum 

 and on the propodeum above the petiole; anterior, parapsidal and lateral grooves 

 distinct; mesopleurse impunctate, shining, except the anterior swelling which is 

 finely punctured ; propodeum except above the petiole shallowly reticulated, the 

 area on the side smooth and shining; the middle coxEe are placed far posteriorly, 

 in juxtaposition to the posterior, the body being considerably elongated ; the 

 furcnla has very short divergent tynes. 



The wings are hyaline. The longer tibial spur is more than one-half the 

 length of the metatarsus; the latter is about one-fourth longer than the remain- 

 ing joints united. The tarsal claws are very small and mostly broken off in the 

 type, but in the remaining one the inner ray seems to be stout and the outer ray 

 rudimentary (Fig. 51). 



The petiole is sparingly punctured above and at the base of the sides, the apex 

 of the sides being transveisely wrinkled ; it is more than twice as long as the 

 distance from its insertion to the metanotum. Abdomen round, polished. 

 Length 6 ram.

Eed ; face, cheeks and temples, scape beneath, trochanters at base and tibial 

 spurs and apex of petiole yellow; rest of posterior legs and base of the petiole 

 brown ; abdomen and propodeum around the coxse black. Head seen from above 

 truncate behind, rounded in front, the anterior edge prominent and emargi- 

 nate mesally between the eyes; these reaching to the posterior edge; ocelli 

 farther from each other than from the compound eyes. Profile broad, the tem- 

 ples linear above and widened below; malar space moderate; antennse inserted 

 below the middle of the eyes. From in front the eyes are prominent; their 

 inner margins diverging below ; face moderately, finely punctured ; temples and 

 cheeks much more sparingly; forehead more closely and coarsely punctured, the 

 vertex smooth.
