Family LARRID^. 



Most of the members of this family described from Australia 

 belong to the genus Pison, Jurine. They are medium-sized 

 wasps, generally black, and often ornamented with golden pubes- 

 cence forming bands or fascife on the segments of the abdomen. 

 Very little is known of their habits, but Smith says " that these 

 insects are nest-builders, and that they construct cells similar to 

 those of Pemphredon, and store them with spiders for their 

 young." In the Transactions of the Entomological Society of 

 London, Vol. II. (1837-40), Shuckard gives a long account of the 

 genus, and describes several new species Smith, in the Proceed- 

 ings of the same Society for 1869, catalogued those previously 

 described, and added a number of new ones from Australia, and 

 also formed the genus Parapison, under which he described three 

 species from India, Ceylon, and this country. The third genus, 

 Tachytes, Panzer, the European species of which are captured 

 in sand-banks according to Westwood, are represented in this 

 country by four described species, all about half an inch in length, 

 and of a shining black colour.
