in two male specimens (Text-fig. 180) from the Rennell Island. They are 

 predominantly yellow, all yellow spots and bands being unusually extended, but 

 otherwise I cannot separate them morphologically from the other specimens of 

 L. histrio. Dr B. Petersen (of Copenhagen) tells me that there are some similar 

 cases in the other groups of Hymenoptera of the Rennell Island which are regarded 

 as endemic subspecies. A further study and more evidence may prove that such 

 a segregation better serves our needs, but for the time being I do not wish to name 

 this form, not knowing the females and not being able to separate for example 

 the specimens from the other islands of the Solomons from the Malayan or Indian 

 specimens, even at the subspecific level. 



L. histrio probably ranges in the northern parts of the Indian subcontinent with 

 the mainly Mediterranean L. intermedia Illiger and both species are similar in 

 colour and stature. L. histrio, however, differs from L. intermedia in having 

 generally finer puncturation, for example much finer on the hind femora, and the 

 dorsellum is not armed. Another similar species, the North Indian L. darjilingensis 

 Mani, has a much shorter ovipositor.
