A. viatica is also found. The Sphegidae appear to be equally 

 numerous both in the old and new world. Some of the genera 

 are very local, as Trigonopsis, found hitherto only in Brazil. Tlie 

 genus Pelopoeus is very widely distributed, but is not found in 

 northern Europe ; it occurs in the South of France, in Italy, Spain, 

 Africa, India, the Indian Archipelago, China, Australia, and is 

 very abundant both in North and South America. The brilliant 

 insects belonging to the genus Chlorion are widely distributed in 

 the tropics ; four of the six known species are eastern ; one occurs 

 in North, the other in South America. No authentic record is 

 known of the occurrence in England of the type of the genus 

 Sphex ; it is found in Southern Europe and in North Africa ; the 

 genus is found in Australia, and indeed in all parts of the tropics, in 

 India and China, even in their northern provinces. The beautiful 

 genus Ampulex is, I believe, strictly intertropical ; twelve species 

 are known, eight belonging to the old, and four to the new world ; 

 the type, A. compressa, is found in India, China, Java, and through- 

 out the Eastern Archipelago. 



The LARRiDiE, with a few exceptions, are inhabitants of the 

 warmer regions of the globe. The type of the genus Larra has 

 been recorded as a British species ; but its title to that distinction 

 is extremely doubtful. The geographical distribution of some of 

 the species is worthy of notice. Larra aurulenta occurs in China, 

 the Philippines, India, throughout tlie Eastern Archipelago, and in 

 Africa from the Cape of Good Hope to Sierra Leone ; we are 

 acquainted with twenty Asiatic species, and the same number 

 of African ; the new world is known to possess at least thirty 

 species. The very closely allied genus Tachytes is generally dis- 

 tributed, and numerous in species, forty having been described ; 

 two are found in England ; the range of individual species is appa- 

 rently very restricted. This genus was believed to occur almost 

 everywhere except in Australia ; but four species have been found 

 in the latter locality, and one in New Zealand. 



The species of the genus Bemhex, although very generally dis- 

 tributed, have not occurred in Great Britain. The type, B. rostrata, 

 is found throughout Southern Europe, in North Africa, and in 

 Finland. B. olivacea has apparently a wider range, being found 

 in Southern Europe, in Algeria, and in Tranquebar ; about fifteen 

 species are found in Africa, six in Australia, four in India, seven 

 in South America, and about the same number in North America. 

 The very closely allied genus Monedula has only occurred in 

 North and South America.
