shield resembles that of the male; it is, however, slightly wider; 

 the bare spaces are present and similar to those of the male. The 

 four vertical hairs are distinct. 



Fig. 24 represents the ventral side of the female. Except the hairy 

 sterual shield which is already mentioned by Berlese, the animal 

 is provided with a genital, a ventral and an anal shield. The genital, 

 shield is rounded anteriorly, straight posteriorly. lts posterior margin 

 runs parallel with the anterior margin of the ventral shield. The 

 two shields nearly touch one another. The ventral shield is rounded 

 posteriorly and a little longer and wider than the genital one. The 

 anal shield shows its cribrate portion behind the postanal hair. The 

 sternal shield is less hairy than the whole venter. The anterior 

 portion of the genital shield is hairless, whereas the posterior portion 

 of it, the ventral shield and the whole venter are very hairy. The 

 peritrema is long, extending beyond coxae 2. The coxae are like 

 those in the male. 



As the other particulars are represented badly too by Berlese, 

 I don 't hesitate to give new descriptions and figures of them too. 



Fig. 25 represents the epistome of a nympha. It is long, trian- 

 gular, with rounded top; the sides of it are scarcely denticulate; 

 the top however provided with long pointed irregular cusps. 



Fig. 26 shows us the mandibles, without any teeth, slender, 

 distally curved inward, with a rounded end, which remembers us 

 of a blunt incisor. On the inner side both fingers are provided 

 with a hyalin thin membrane. 



Fig. 27 is a representation of the hypostome. lts outer malae 

 are thin, blade-like, truneated distally. lts inner malae are partly 

 fused, and distally provided with the usual numerous slips, of 

 which the most inward is the longest. The hypostome is as usually 

 provided with 3 pair of hairs ; one pair on the base of the outer 

 malae, and two pair on the base of the hypostome. In the median 

 line of the ventral side of the capitulnm you will observe 14 

 transverse rows of very fine denticulations, of which the three 

 foremost are delineated by me between the two hindermost pair 

 of hairs of the hypostome. These rows are not straight but some-
