The Non-Combed Eyed Siphonaptera 
ventral margin, 2 more bristles being placed on the lateral surface. 
On the inside of the apical margin there are 16 bristles and hairs. 
The above description is taken from a $ received from Dr J.N. Wagner, 
of Kieff. The is not yet known. 
The insect has so far only been found on Erinaceus auritus in 
West Turkestan. 
2. Group of species. 
Epistemum of metathorax separated from sternum (see diagram, p. 25), the 
latter bearing a bristle which is as long as that situated on the episternum. Hind- 
femur angulate centrally at the widest point, fifth segment of fore- and midtarsi 
with three spine-like bristles ventrally at apex, the lateral ones being very stout 
in . Clasper with two distinct free processes ; manubrium long ; penis without a 
kind of brush near apex. To this group belong Species No. 6—13.

Head. The rostrum reaches to the apex of the forecoxa. The 
proportional lengths of the segments of the maxillary palpus are 12, 15, 
11, 20. The subapical row of bristles of the occiput contains 6 bristles 
on each side. The first antennal segment of £ bears 4 hairs at the 
hinder edge and a transverse row of about 7, there being proximally 
to this row 2 or 3 additional hairs. In the the apical projection 
of the first antennal segment has 2 or 3 hairs at the tip, and about 
4 minute ones on the outer surface of the segment as well. 
Thorax. The number of bristles in the row on the pronotum varies 
from 13 to 16, on the mesonotum from 12 to 14, and on the metanotum 
from 11 to 12, the bristles of the two sides being counted together. 
The mesosternite bears 5 bristles on the side, the episternum of the 
metathorax one, and the epimerum 10 to 17 in two rows (5 to 8,5 to 7).
