122 MR. F. SMITH ON THE GEOGKAPHICAL DISTBIBUTIOK 



found in the East, nearly twenty in Africa, the rest in North 

 and South America, with the exception of two or three from Austra- 

 lia. L. aurulenta is one of the most widely distributed species of 

 the genus, it is found in China, India, throughout the Eastern 

 Archipelago, at the Cape of Good Hope, and on the Gambia. 



The genus Pison is composed of species that do not appear to 

 be abundant in any locality, though they occur in all quarters of 

 the globe. About twenty-four species are described ; four are 

 added to the list from the Archipelago : individual species do not 

 appear to be widely distributed. 



The family Crabeonid^ is one of great extent, the majority of 

 its members being European. Of the genus Trypoxylon about 

 twenty-two species were described previous to Mr. Wallace's re- 

 searches, two only being known from India ; nine were discovered 

 in the Archipelago; the genus also occurs in Europe, Africa, 

 and North and South America. 



Of the extensive genus Crabro the majority of the species are 

 found in Europe and North America ; two are now recorded 

 from Borneo, one from Celebes, and one from Aru ; two species 

 only were previously known from the East. 



Of the geuus Fsen one species was found in Celebes, and one 

 in Mysol. The genus had not previously been recorded from the 

 East ; four European species were known, and one Brazilian. 



To the genus Cerceris five new species are added from the Ar- 

 chipelago ; thirty are found in Europe, and about the same num- 

 ber in Africa ; sixteen are recorded from China, India, Sumatra, 

 and Java ; and three or four are known from Australia. 



Of the genus Fhilanthus four species are kno\sTi from India 

 and Ceylon, and Mr. "Wallace discovered one in Celebes. Species 

 belonging to this genus do not appear to be very numerous in 

 any locality : four occur in Europe, ten are known from Africa, 

 seven from North America, and about the same number from 

 South America. 



In no family of the Aculeata have Mr ..Wallace's researches added 

 so much to our knowledge of geographical distribution as in that 

 of the Vespidse. To the rare genus Gayella, belonging to the 

 EuMENiD^s, a new species from Borneo is added ; the two pre- 

 viously known are from Chili. 



Of the genus Eumenes about ninety species were recorded, 

 when through Mr. Wallace's researches eighteen new ones were 

 discovered in the Archipelago. The geographical distribution of 

 some species is very extensive : as an example E. arcuata may
