The morphology of the Chigoe is well-known from the work of Karsten, 
which is far superior to that of Bonnet. We abstain from a detailed description oi 
the insect, as the essential features of its structure have been mentioned in the 
Introduction to the present paper. For comparison with the other species of 
Sarcopsyllidae we figure, however, the fifth tarsal segment (PI. IV, Fig. 28), and the 
clasping organs of the $ (Fig. F). 
For the biology of the insect consult Karsten (1 864), Guyon (i 865-1 869), 
Taschenberg (1880), and Rabary (1902), /./. c.c. For bibliography see Huber, 
Bibl. Klin. Ent. I (1899). The species occurs on man and various mammals in the 
Neotropical region from Mexico to the northern districts of Argentina, and has been 
introduced into West Africa during the second half of the last century. It has now
