170 SMITH ON HYMENOPTEEA OF AllU ISLANDS. 



incrassate, not denticulate ; the tarsi 5-j()iuted. Abdomen petiolated, 



the petiole as long as the abdomen; the ovipositor as long as the 



petiole and abdomen united. 



This genus is founded on the examination of a single individual, which 

 in general appearance exactly resembles the smaller species of the genus 

 Megisnhus', on examination, however, it will be found that it differs 

 from that genus in the neuration of the anterior wings ; its femora are 

 not denticulate, in which character it differs from both Megischus and 

 Stephanus ; with the latter genus it agrees in having 5-jointed tarsi. 



1. Stenophasmus ruficeps. -S. niger; capite et antennarum basi 

 rufis ; ovipositore tarsisque pallid^ testaceis ; petiolo abdominis cylin- 

 drico ; alis subhyalinis. 



Female. Length 5 lines. Black, slightly shining; head globose, red 

 and sprinkled with white hairs, and delicately striated transversely.

 sprinkled with erect white hairs ; the tarsi pale rufo-testaceous with

 stain along the centre of the anterior pair ; a hyaline streak crosses
