Legs. — The forecoxa bears eight or nine hairs near the anterior edge aud a 

 scries of five at the hinder edge, there being no hairs on the posterior portion of the 

 outer surface. The mid- and hindcoxae bear at the apex posteriorly one bristle, and 

 anteriorly a row of about six. The femora have no bristles at the ventral edge near 

 the base ; there are two ventral bristles near the apex one on each side, that 

 on the outerside being the longer. Each femur bears one hair on the innerside 

 towards the base, and the anterior femnr several hairs on the outer surface. The 

 tibiae are stout and do not bear any hairs at the ventral edge, apart from the apical 

 bristles. The anterior tibia is not longer than the fifth tarsal segment (claw 

 excluded). The spine-like bristles of the tibiae and tarsi are very heavy. The 

 longest dorsal apical bristle of the midtibia reaches beyond the middle of the 

 second tarsal segment. The hindtibia bears three hairs on the outer surface 

 towards the ventral side. The fourth segment of all the tarsi is stout and cup-shaped. 

 The first segment of the hindtarsus is not quite half the length of the tibia. 

 The measurements of the tarsal segments are : — 



Modified Segments. — -For the clasping organs compare PI. VII. fig. 2. 



The manubrium (m) is narrow and curved upwards, the clasper very large 

 and rounded at the top, bearing a great number of short hairs at and near the edge- 

 The finger (f) is very strongly chitinised, slender, produced into a ])oint, and bears 

 a row of hairs on the inner surface. There are, besides, three very short hairs at the 

 hinder edge near the apex, and some longer ones farther down. The ninth sternite 

 is narrow and bears ventrally a series of single hairs. The eighth tergite (VIII. t.) 

 of the c? is enlarged and bears many bristles, three of which standing at the edge 

 are long. The eighth tergite of the ¥ bears a dense patch of bristles at the 

 apex on the innerside (PL VII. fig. 3), and some longer ones on the outerside 

 (PI. VII. fig. 4). 



Length : c?, 3-08 mm. ; ¥,4-1 mm.

Weyenbergh proposed the generic term Malacopsylla for the species of 

 flea described by him previously as Pulex grossiventris. The diagnosis of the 

 genus is very short. The author says : " . . . Pero cuando mi F. testtido pertenece 

 al ge'nero ITcctnpsylla, eutonces es cierto qui mi P. grossiventris non puede 

 pertenecer al mismo genero, porque la diferentia en el habito general es demasiado 

 grande, d pesar de que d la primera vista haya alguna semejanza, lo que, por lo mas, 

 puede indicar una aliacion entre los g(5neros. ... P. grossiventris probablemente
