372 MR. J. N. H ALBERT : NOTES ON ACARI, 
lobes (Hull, 25 ; Halbert, 23, 24), I believe there are at least four closely- 
allied species in these countries. The male and female o£ three of these are 
now known to me, and although the general structure is much alike, the 
males possess excellent characters in the form of the mandibular calcar. 
These three species are L. {E.) italicus, Berl., L. (E.) michaeli, sp. nov., 
and L. [E.) major, sp. nov. The male of L. {E.) tenuipes, Halbt., has not 
been discovered, and until this is found I must rely on the characters of the 
single specimen described (23, p. 78). The females in the case of two of the 
species, i.e. L. {E.) italicus and L. (E.) michaeli, are difficult to separate; 
indeed, the one description would suit both species almost equally well. 
Unfortunately the males, as in many Acarid genera, are decidedly rare ; as 
an instance, I may mention that out of a gathering from one locality of about 
one hundred examples of "italicus" aggregate three males were found, and 
this only by close searching of moss brought home from a suitable locality. 
The species frequent wet moss, liverworts, &c., and may be found amongst 
submerged mosses growing on stones in mountain-streams, in company with 
mites of the genera Calonyx, Panisus, and Aturus. 
The female of L. (E.) italicus, Berl., is described in 4, p. 234, and is 
excellently figured by Dr. Berlese in a later paper (" Eedia," vi. pi. 19. fig. 35), 
while the male is briefly described in 10, p. 34. In view of the great 
similarity of the females of these species, it will probably be sufficient to give 
a short description of L. (E.) italicus, and then briefly tabulate the chief 
characters of the four species. Figures of the male mandibular calcars of 
three species and of the female of L. (E.) major, sp. nov., are given in the 
present paper. 
L. (E.) italicus, Berl. Female. Shape pyriform. Dorsal shield large, 
reaching end of body; sides often slightly rounded, surface reticulate. Hair 
armature weak on centre of dorsum, much stronger and somewhat adpressed 
at the margins, where they are arranged in a double row. There is a raised 
tubercle near the posterior margin. Epistome of the tricuspid Episeius type. 
Sternum rather large and wide ; both the front and hinder margins are 
slightly concave, and the latter reaches to middle of the third coxse. Genital 
plate hatchet-shaped ; hinder margin straight, standing well beyond the 
fourth coxse. Ventro-anal plate large, much broader than long (length 210 /x, 
breadth 300 /u.) , flattened in front; side margins concave near centre, surface 
with irregular lozenge-shaped markings. Between the last two plates are 
three pairs of ver)' minute plates arranged in two rows. Peritreme broad 
and strongly sinuate. The united plates of the peritreme and metapodia 
extend beyond the last pair of coxse in an obtusely-pointed triangular form. 
Leo's very long, with attenuated tarsi, and the ambulacra have bristle-like 
lateral lobes and a lanceolate upper lobe. Length about 640 /x, breadth 
420 fi.
