 the negroes suffer much from the attacks of this fly, 

 which frequently deposits its eggs in their nostrils whilst

 that, in some cases, death ensues. 



Another dipterous insect is called '' Marimbouda 

 santa," the holy wasp, having, as the people say, a 

 priest's coat ; the insect is a species of the genus Sargus, 

 and is distinguished by having a yellow cross at the base 

 of the abdomen. 



Mr. Peckolt has also sent a phial containing a speci- 

 men of a caterpillar, that lives in companies of from 

 thirty to forty ; they spin together a large cocoon, as 

 big as a man's head, in which they undergo their change. 

 This caterpillar is ornamented with a number of fringed 

 spines or branches, and is very destructive to various 

 shrubs. It probably belongs to some species of butter- 

 fly. [See Proc. Ent. Soc. 1868, p. xv.J
