wbat convex forward. — The first article of the palp bears ven- 

 trally and distally a more or less spool-shaped hair, with a striated 

 meinbraue on one side. 



The epistome of the male (Fig. 28) resembles that of the nympha; 

 its sides, however, are not denticulated. The mandibles (Fig. 29) 

 are peculiar. The fixed finger is crooked toward the median line, 

 hyalin, toothless. The movable one is for the greater part fused 

 with its appendage (copulatiou organ), broad, flat, distally wider, 

 and acute. Fig. 29 shows us the mandibles in usual position, whilst 

 fig. 30 is a ventral aspect of them, when they are pressed between 

 the object-glass and the covering-glas. Fig. 31 shows us the cf 

 hypostome. The outer malae are more like those of some species 

 of Parasitus. In the median line of the ventral side of the capi- 

 tuluin 14 rows (convex forward) of minute denticulations. The 

 first joint of the palp ventrally and distally with a more or less 

 spool-shaped hair, with a membranous outer side. 



The epistome of the female is very well represented by Michael 

 (Trans. Linn. Soc. London. ser. 2, vol. 5, pi. 32, fig. 10 and 11). 

 The mandibles are exactly like those of the nympha (Fig. 26), 

 not as drawn by Berlese (Ac. Myr. Scorp. Ital. 52, 2. fig. 8). 

 The hypostome (Fig. 32) shows wide, well chitinized outer malae, 

 and the first joint of the palp ventrally the same characteristic hair 

 as the nympha and the male. — In the median line of the veutral 

 side of the capitulum you will observe the same markings as in 

 the nymph and the male. 



9. Haemogamasus michaeli Oudms, nov. sp. 



(With Plate VI, fig. 33-39). 



Nympha unknown. 



Male unknown. 



Female. Length 975 (i. Shield 970 p. Colour and shape exactly 

 like those of Haemogamasus hirsutus Berl. 



The dorsal shield (Fig. 33) has its sides more parallel than in 

 the above named species, and it is posteriorly wider and rounder.
