most nortliern locality known for this genus of insects. The only 

 species hitherto found in the eastern hemisphere have occurred in 

 Australia and Tasmania, none having been found north of the for- 

 mer continent previous to the captures made by Mr. Wallace. 

 Many species and genera are found in similar latitudes in Bi'azil. 



The family Scoliad^ is one of great extent, and of wide geogra- 

 phical distribution, some species being found in all the quarters 

 of the globe. Not a single species is found in England ; but five or 

 six occur in Europe. Some species have a wide distribution ; Scolia 

 erythrocephala is found in France, Italy, Spain, Algeria, and Egypt. 

 Thirty new species were discovered in the Archipelago ; one, the 

 S. dimidiata, is found in India, Celebes, Bachian, Gilolo, Ceram, 

 Bouru, and Amboyna. The distribution of other species is equally 

 extensive, as will be seen on a reference to the table. 



The PoMPiLiDiE is a very extensive family, nearly four hundred 

 species having been described ; the typical genus Pompilus con- 

 sists of upwards of two hundred and ninety species, fifty- six 

 having been discovered in the Eastern Archipelago. Some species 

 are known to have a wide distribution : P. analis of Fabricius, 

 originally known as an Indian species, has been found in Celebes, 

 Bachian, and Java ; Agenia llanda inhabits Singapore, Borneo, 

 Celebes, Key Island, and Ceram ; Macromeris violacea is perhaps 

 the most generally distributed insect belonging to the family ; it 

 is found in India, China, Borneo, Celebes, Java, Aru, Ceram, Bouru, 

 and New Guinea. 



The beautiful genus Ampulex is exclusively tropical ; it is found 

 in India, Africa, and South America. The type, A.compressa, occurs 

 in India, China, Java, Celebes, and the Mauritius ; four new spe- 

 cies are added from the Archipelago, the genus now consisting of 

 fifteen species. 



Much information respecting the distribution of the Sphe- 

 GIDJ3 will be found by reference to the table. Pelopoeus spiri- 

 fex, a species common to Europe, was found by Mr. "Wallace 

 in the island of Timor. Spliex sericea of Fabricius is found iu 

 the Philippines, throughout the Archipelago as far south as the 

 island of Timor. Extensive as this distribution certainly is, it is 

 not comparable to that of SpJiex argentata, which occurs in the 

 south of Europe, in India, Sumatra, Java, Celebes, Aru, Bachian, 

 Dory, and Ceram ; in Africa it has been found at Congo and Sierra 

 Leone ; in America, at St. John's Bluff, East Florida. 



The genus Larrada is widely distributed : there is no British 

 species ; but four or five occur in Europe, about thirty have been
