HYMEXOPTERA FROM BORNEO. 25 



Mesonotum with 3 spots in a curve ; the head black 

 and testaceous, the collar broadly, distinctly round- 

 ly narrowed, no transverse keel below the an- 

 tennae ... ... ... .. iiigromaculatus. 



D,— On some Vespidae. 



^ Icaria parvimaculata, sp. nov. 



Black, a short line on the base of the mandibles, a small 

 mark on the sides of the clypeus shortly above the middle, 

 2, almost united, lines on the base of the post-scutellum, aline 

 down the sides of metanotum, straight on the inner, rounded 

 on the outerside, a short line, dilated backwards in the middle, 

 a narrow line on the apex of the 2nd abdominal segment and 

 a narrow indistinct one on the apex of pronotum, pale yellow ; 

 wings hyaline, the apex broadly smoky in front, the stigma 

 and nervures black in front. 9 . 



Length to end of 2nd abdominal segment 6 mm. 



Marup. May (J. Hewitt). 



First abdominal segment as long as the second ; its base 

 narrow, the apex dilated roundly above, becoming gradually 

 higher above ; seen laterally the segment becomes gradually 

 widened from the base to the apex ; the 2nd segment cup- 

 shaped, roundly narrowed at the base, shorter than it 

 is wide at the apex, closely distinctly, almost uniformly 

 punctured, the punctures more or less interlacing ; the first 

 segment smooth, shining ; both are sparsely covered with 

 white pubesence. Clypeus very shining, very sparsely punctur- 

 ed, almost smooth on the lower, more distinctly and closely 

 on the upper half ; it is slightly broader than it is long and 

 ends in a distinct tooth. 



In its black colouration this species approaches I. lugu- 

 bris, Sm. and I. tlavolineala, Cam., but it cannot be confound- 

 ed with either ; in form it more resembles i". moldy ana and 

 /. ornaticeps.
