In the class arachnides, we meet with several species of 

 spiders, one kind of which the natives tell long stories 

 about, as being of a very poisonous nature ; but no one 

 can be found who has ever known any injury done by that 

 animal. 



In the suctoria tribes, we meet with an abundance of 

 fleas, (Pulex. Lin.) which are very noisome in the summer 

 months. 



In the coleoptera order, there are to be found several 

 species of carabici, among which, we observe the Carabus 

 agrorum, (Oliv.) There also occur in this order, several 

 species of pimeliae, tenebrionites, and curculionites. 



In the order orthoptera, we meet with myriads of 

 cockroaches, (Blatta. Lin.) and the mole-cricket, (Gryl- 

 lus vulgaris. Oliv.) and the field-cricket, (G. campestris. 

 Oliv.) In this order, too, we find several species of 

 locusts, the most formidable of which, is the African locust, 

 (Acrydium migratorhis. Cuv.) alluded to in a former 

 letter.* 



In the order hemiptera, we find several species of cimices, 

 in which we recognize the Cimexlectularius, (Lin.) much 

 to be dreaded by the weary traxeller when he retires to his 

 night's repose. 



In the order neuroptera, we notice several species of 

 dragon-flies, (Lihdlula. Fab.) eminently distinguished for 

 the brilliancy of their hues. 



In the order hymenoptera, we observe several species of 

 ichneumonides, among which, occur the Ichneumon mani- 

 festor, and the I. bidentatus, (Oliv.) AVe also observe 

 among the ants, the Formica rufa, (Oliv.) and like- 

 wise several species of bees, among which, may be found 

 wild, the common honey-bee, (Apis nuJliJica.) 



In the order lepidoptera, we meet with the usual num- 

 ber of butterflies, (PapiJio. Lix.) and moths peculiar to 

 warm countries, among which, we find a large sphynx, 

 and the silk-worm, (Bomhyx mori. Lin.) 



At last, we find in the order diptera, the usual quan- 

 tity of flies and mosquetos, common to tropical climates,
