THE CHIGOE IN ASIA. 

 BY W. F. H. BLANDFOED, M.A., F.Z.S. 



The sand-flea, chigoe or nigua {SarcopsylJa penetrans, L.), is one of 

 the most troublesome pests in Tropical America and the West Indies to 

 man and various domestic and wild animals, and, as such, has been the 

 subject of numerous papers and monographs, chief among which are 

 those of Karsten, Gruyon and Bonnet. The female flea burrows into 

 the skin, usually of the feet, but also of any other accessible region. 

 After she has effected an entrance, her abdomen swells into a spheri- 

 cal mass which, unlike the abdomen of a queen Termite, shows no 

 trace of the component segments, except at the extremity, and of 

 which the tracheae suffer remarkable changes and lose their character- 

 istic spiral threads. In this situation she ejects her eggs after they 

 have reached maturity ; the larvae, according to Guyon, are free-living 

 and not parasitic on the host of their mother, on whose remains they 

 are said by Bonnet to feed in part.
