124 MR. F. SMITH ON THE GEOGRAPHICAL DISTRIBUTION 



South Africa, and I believe no one has recorded the capture of a 

 species south of the Isthmus of Panama. 



To our knowledge of the geographical distribution of the tribe 

 Anthophila, which contains the various families and genera of 

 bees, much has accrued through the exertions of Mr. Wallace. 

 Of the genus Frosopis only a single species was known from the 

 East ; our table will show that two have been discovered in Mysol, 

 one in Key Island, and one in Dory. 



The genus Sphecodes is very rare in India and the adjacent 

 islands ; one species was discovered in Celebes. 



Of the genus Nomia seventeen species are recorded in tlie tabu- 

 lar list, not a single example having been previously discovered in 

 Malacca, Singapore, Celebes, Aru, Grilolo, or Mysol. 



Nomada is a genus of very rare occurrence within the tropics ; 

 one species was, however, found in Ceram, and one in Timor. Pour 

 new species of Honey-Bees were discovered — two in Borneo and 

 two in Celebes. 



Of the genus Trigona, which is composed of the stingless species 

 of Honey-Bees, two only were previously described from the East ; 

 nine new ones are now added to that number from the Eastern 

 Archipelago. 



The Tenthredinid^ are apparently rare insects within the tro- 

 pics. One or two interesting discoveries of genera may be noticed, 

 namely a species of Oryssus from Aru, a XipTiydria from Aru, and 

 a second species from Amboyna ; it is also very interesting to find 

 that the genus Tremex inhabits the same regions — a fine new 

 species having been discovered in Borneo, and another in Aru.

 Hymenoptera inhabiting the Eastern Archipelago, and their geo- 

 grapliical distribution : —
