Brazilimi Insects, 135 



" Mariinbouda auiarella " is Pelopams fistularis of 

 Dalilbom, a house-wasp ; it makes a clay nest^ and stores 

 it with spiders. 



^' Marimbouda da Casa ^' is Tri/poxylon alhitarse; it 

 makes a clay nest in the form of a long cylinder ; it is called 

 the " house- wasp '' because it builds its nest especially in 

 roomSj but also out of doors on the vine, &c.; there are 

 from four to six divisions, and in each cell is laid one 

 egg ; the cell is filled with some kind of spider, and her- 

 metically sealed ; it is curious that precisely the required 

 number of spiders is stored up, just sufficient to perfect 

 the wasp, since none are ever found after the insect eats 

 its way out of its earthen cell. 



'' BisuiTa amarella pignena^^ is the Centris ferruginea 

 of St. Fargeau ; it makes its nest in the ground, and is 

 very spiteful and vicious. 



" Bisurra amarella grande^^ is the Gantris fascata of 

 St. Fargeau. 



" Marimbouda de cachorro^Ms the Sphex fulvipennis ; 

 it constructs its nest under ground. 



" Marimbouda accii" is a large species of the genus 

 Fcpsis ; it is the enemy of the large bush-spider; it is 

 astonishing to see this insect attack the uncouth spider, 

 ten times as large as itself, and overpower it ; but it is 

 always the victor. 



" Marimbouda tatu" is Ghartergiis apicalis ; it is said to 

 be a very furious wasp ; its nest is built on trees, and if 

 in any way disturbed, a swarm of the wasps rush furiously 

 to the attack. 



"^ Marimbouda preta da bunda" is Liogastra hicolor of 

 Perty ; this bee is described as a very furious wasp, and is 

 said to be very widely spread over the country. 



The collection contained a few insects of other Orders . 

 Among the Biptera, there is one which is called the 

 *' Warega^^ fly. This is said to be the pest of both man 

 and animals ; it is a species of Mtisca, and is said to lay 

 its eggs in the skin ; large and terrible swellings are 

 formed ; the mode of extracting the maggot is to cut an 

 opening, and to press it out, — a most painful operation ; 

 these wounds are very difficult to cure. 



Another dipterous insect is called the '^Berna^^ fly, 

 which deposits its eggs in wounds, both on man and 

 beast ; it is a species of the genus Trypeta, and is 

 remarkable from having the apical segment of the abdo-
