M. splendidus. — One female was swept from reeds at South- 

 wold in a salt-marsh, August 1st, 1900. Bignell was sceptical of 

 this determination, but the insect agrees in every particular with 

 Eev. T. A. Marshall's description. 



M. xcmtJiocephalus. — Donisthorpe has given me a female 

 which he took in Co. Kerry, June, 1902. 



DESCRIPTION OF A NEW GENUS AND SPECIES OF 

 CRYPTIN^ (ICHNEUMONID^) FROM BORNEO. 



By p. Cameron. 



Palmerella, gen. nov. 

 Areolet minute, punctiform, the recurrent nervure received at its 

 apex ; the transverse median nervure received shortly behind the 

 transverse basal ; transverse median nervure in hind wings broken near 

 the bottom ; radial cellule elongate ; disco-cubital nervure unbroken. 

 Metanotum with one transverse keel, and with a square area in the 

 middle of the base, behind the keel ; the sides at the apex armed with 

 long spines ; the spiracles ovate, of moderate size. Abdominal petiole 

 rather stout, broad, curved, longer than the second segment. The 

 third antennal joint not much longer than the fourth. Hind legs very 

 long. Palpi long, the maxillary reaching to the middle coxae. Scu- 

 tellum roundly, iDroadly conical ; the apex has a long, steep slope. 

 Eyes large, parallel. Thorax fully three times longer than wide ; the 

 head is wider than it ; its front is depressed and is keeled down the 

 middle ; there is a complete metapleural keel. The parapsidal fur- 

 rows extend from the base to the apex of the mesonotum. 



The type of this genus differs from the other Mesostenini 

 (the group to which it belongs) in having the body and legs 

 black : the scutellum is much more prominent than it is with 

 Mesostenoideus or Biiodias, and, more particularly, in being 

 steeply declivous behind ; the hind legs are longer and more 

 slender, and the abdomen shorter and narrower, its j)etiole 

 stouter and of more equal width, as well as being longer com- 

 pared with the second segment. Looked at from the sides the 

 base of the metanotum is seen to be depressed, the post-scutellum 

 appearing behind the depression as a small tubercle. 



The type of the genus has hardly the appearance of a
