PARASEMUS. 
To the best of my knowledge no formal diagnosis of this genus 
has been published. The following characters are to be inferred 
from its place in two tabulations (Ann. Soc. Ent. Fr. 1894) :— 
Palpi of ordinary length, intermediate coxe widely separated, 
mesosternum appearing only as the reflexed margin of the meta- 
sternal lobe, clypeus emarginate close to the eye and rounded at 
the apex, metasternal lobe not passing the intermediate coxe, 
prosternal lobe not passing the front cox, antennal club three- 
jointed, second joint of posterior tarsi two or three times as long 
as basal joint, apical joint of maxillary palpi cylindric, a single 
subsutural stria, basal two joints of posterior tarsi not soldered 
together, posterior tibie obliquely truncate at the apex, form 
subhemispheric. 
T have in my collection a number of species which must either 
be referred to this genus or be regarded as representing a new 
genus closely allied to it. They all agree more or less perfectly 
with the diagnosis of Parasemus that I have given above, their 
variations from it being in respect of characters that need not be 
regarded as generic; thus the basal joint of the hind tarsi is in 
every instance notably shorter than, though in some instances it 
is more than Aalf as long as, the second joint; and the form of 
the body is by no means constantly subhemispheric, but this 
latter character (7.e., the form of the body) is I think manifestly 
only specific. The character that I feel most doubtful about is 
‘“basal two joints of hind tarsi not soldered together.” JI am 
not sure that I understand this expression. In the insects be- 
fore me the basal two joints are very closely connected and the 
suture (though perfectly manifest under a microscope) is very 
fine, but the two joints are certainly distinct from each other. 
A remarkable character common in a greater or less degree to 
them all consists in the compression and dilatation of the femora 
—especially the four anterior ones. These four might be called 
“ subcircular” being almost as wide as long, the hinder margin 
of the intermediate being however not evenly rounded but feebly 
angular in the middle; in repose the tibize are almost hidden 
under these flat plate-like femora only their apex protruding. As 
M. Guillebeau does not refer to the femora in Parasemus this 
character does not help me to determine whether my specimens 
are Parasemi. 
I find that two species which I have previously referred to 
Litochrus must take their place among these present insects, viz., 
L. suturellus, Blackb., and L. lateralis, Blackb. At the time I 
described them the suture between the basal two joints of the 
hind tarsi escaped my notice and [ mistook the two joints for a 
single one. I have now placed a hind tarsus of all the species in
