ferred to any of the three other genera badly established by Tomosvary 
or Cook, and a new name is necessary, but being unable to deter- 
raine my species, to state whether it must be E. Latzelii Cook or 
a form hitherto unknown, I will not propose any name either for the 
genus or the species, but, having pointed out the difficulties, confine 
myself to some additional remarks on my animals. 
Both specimens are adult; one of them is a male, the other 
a female. The male measures 1*22 mm. in length and *48 mm. 
in breadth; the female 1*18 mm. in length and it is as broad as 
the male. They agree rather well with LatzeTs description, with 
exception of the two points already mentioned. The shape, thick- 
ness and relative length of the branches, flagella etc. of the an- 
tennæ is easily studied in my fig. 4 a, showing the left antenna 
from below. The relative length (and the pubescence) of three pairs 
of tactile setæ are seen in fig. 4 b, 4 c and 4 d, all drawn with 
the same degree of enlargement; the essential points of the adorn- 
ment of the surface and the lateral margin of the trunk are exhi- 
bited in fig. 4 d, 4 e and 4 f. — The anal segment (fig. 4 g and 
4 i) is interesting. The tergum as usual with three pairs of setæ 
(fig. 4 i); those of the submedian pair are inserted near each other, 
scarcely one fifth as long as the breadth of the segment, very ro¬ 
bust, strongly clavate, with the apical portion pubescent; the inter- 
mediate setæ are rather distant from the submedian pair, similar 
in shape, but only half as long; the lateral pair is a little shorter 
than the intermediate, less thick and with the apex acute. — The 
styli (fig. 4 i) are very small. — The sternum (fig. 4 g) with three 
pairs of setæ on its distal half; the posterior pair is scarcely half 
as long as the breadth of the segment, moderately siender, tapering; 
the two other pairs are inserted almost in a transverse row, they 
are siender, cylindrical and not half as long as the posterior pair. 
At the base of the sternum or perhaps belonging to the preceding 
segment is found a pair of setæ which are a little longer than the 
lateral pair and similar in shape. — The anal plate (fig. 4 h and 
4 k) is very different from all others seen by me: the plate itself
