44 ON THE HYMEISTOPTERA OE THE " SKEAT EXPEDITION." [May 7, 



Hah. Borneo (Shelford). 



Antennae black ; the 3rd joint, except at the apex, white. The 

 front and vertex are stoutly, acutely, longitudinally striated ; the 

 face is similarly, but more obliquely, striated ; the outer parts of 

 the head are obliquely, and not quite so strongly, striated. The 

 hinder ocelli are separated from each other by about the same 

 distance as they are from the eyes. The lower tooth of the 

 mandibles is rufous before the apex ; the palpi are dark fuscous. 

 The base of the pronotum is raised ; the raised part slightly 

 projects laterally ; the sides are oblique ; the base is not quite 

 transverse, the edges being rounded ; it bears rcjund, deep, clearly 

 separated punctures. The central part of the mesonotum is 

 alutaceous and impunctate at the base ; the rest of it irregularly, 

 deeply, but not very closely punctured ; this punctured part is 

 bordered by a deep furrow ; outside this it is opaque and aluta- 

 ceous, and bears two thin keels on the outer side- Scutellum in 

 the middle strongly, irregularly punctured ; the centre has a 

 longitudinal keel ; the sides are stoutly, obliquely striated ; on the 

 postscutellum are two stout keels. Propleurss alutaceous and 

 bearing some scattered, shallow punctures. The upper two-thirds 

 of the mesopleurae are smooth and shining, except for an oblique, 

 clearly defined, depressed area ; this has the bordering keels more 

 distinct in front than behind and bears, except at the base and 

 apex, some stout keels ; the lower part is closely, but not very 

 deeply punctured. Sternum smooth. Median segment closely 

 reticulated ; the central portion more closely, rugosely, and ir- 

 regularly than the rest. The basal part of the wings is fuscous, 

 with a distinct violaceous tinge ; the apical part below the radial 

 and second cubital cellules is similarly, but more lightly, clouded. 

 The metasternal fork is short and stout, and obliquely diverges at 

 the apex : behind it is a stout, smooth keel. The front tibiae and 

 tarsi are fuscous ; the four anterior trochanters are broadly white 

 at the base, as is also the base of the hinder tibiae narrowly, the 

 basal joint of the hinder tarsi, and the second joint broadly in the 

 middle. Petiole smooth at the base ; its sides bear stout, oblique 

 striae ; the apical half above is irregulai'ly, coarsely punctured. 

 The hinder tibiae and tarsi are shortly spined. The sides of the 

 median segment are broadly rounded ; the middle transverse ; the 

 abdomen is very smooth, shining, and piceous. 



This comes nearest, of the known species, to the Australian 

 E. princeps AVest.]
