Euckalcomencs, n. gen. 



9 . Mandibles long and broad, forming a rostrum, obtuse at the 

 apex, with three short, strong, blunt teeth along the inner margin, 

 deeply furrowed above. Maxillary palpi four-jointed, the first joint 

 very long, as long as the other joints combined, the second longer 

 than the third, the fourth very short, slender and pointed. Labial 

 palpi four-jointed, short and slender. Clypeus pyriform ; the labrum 

 projecting beyond the apex, very narrowly linguiform. Head of the 

 same breadth as the thorax ; the eyes very deeply emarginate ; the 

 antennae thickened gradually to the apex, the flagellum twice as long 

 as the scape. Pronotum truncate anteriorly ; the median segment 

 short, very steeply sloped posteriorly and deeply longitudinally 

 divided. First abdominal segment slender at the extreme base, then 

 widened and bell-shaped, nearly half as wide at the apex as the 

 second segment, which is longer than the first. The spine at the 

 apex of the intermediate tibiae is very short ; the tarsal ungues are 

 bidentate. Tlie first recurrent nervure is received just before the 

 middle of the second cubital cell, the second is interstitial with the 

 second transverse cubital nervure. The radial cell is broad, shortly 

 appendiculate ; the first cubital cell is considerably longer on the 

 cubital nervure than the second and third united ; the second is very 

 narrow on the radial nervure, almost triangular ; the third rhomboidal, 

 hardly broader on the cubital than on the radial nervure. 



Type E. gilherti, n. sp. 



Pachymenes viridis, Sm., from Aru and P. elegans, Sm., 

 from Batchian also belong to the genus, which is quite 

 distinct from the American Pachymenes, in which the 

 maxillary palpi are six-jointed as in Eunienes. 



Euchalcomenes gilherti, n. sp. 

 $ . Clypeus very narrowly truncate at the apex. A short longitu- 

 dinal carina between the antennse, which are twice as far from each 

 other at the base as from the eyes. The whole insect deeply and
