its sides; when seen from beneath, they appear only as two 
small bodies at the sides of the lingua. The framework sup- 
porting the maxillz and lingua is very complete (see the annexed 
figure), and in all essential points like that of Japyz.

aa, bb, c, principal parts of 
inner framework supporting the 
maxille and lingua; d, inner 
lobe of right maxilla; e, outer 
lobe, and f, palpus, of left max- 
ila; h, lingua; i, paraglossee ; 
k, stipes, and 1, cardo, of right 
maxilla; # x, pieces of frame- 
work supporting lingua; y 6, si- 
milar pieces supporting outer 
lobe of maxilla; z, @, pieces 
connected with the last, and 
supporting paraglossz. 
The labium covers the organs of the mouth almost entirely, 
so that ordinarily only their points are visible in front of it ; 
but, as stated before, they are capable of protrusion to some 
extent, about so much that the lingua becomes visible. The 
labium is deeply bifid, and each half is divided into two pieces 
by a transverse groove (though less markedly than in Japyz) ; 
from the hindmost divisions rise the short conical, hairy, labial 
palpi, which near their apices each carry two long subuliform 
sete. The palpus is much less chitinized than in Japya, and it 
does not articulate properly with the labium. 
Behind the labium appear two oval, transversely placed pro- 
tuberances like warts, on which from six to eight rows of rather 
large depressions with small sete are observed—probably an 
organ of sense affording a substitute for the absence of palpa- 
rium on the labial and maxillary palpi. 
There is no mentum. The hypostoma varies in size, but is 
generally only a small triangular plate near the posterior margin 
of the head. 
The antennez consist of numerous rather long joints bearing 
one or two circles of large sete, besides many smaller scattered 
ones. In the Danish species I have counted from twelve to 
twenty-six joints, often different numbers in the antenne of the 
same individual. The joints are cylindrical, or slightly fusiform ; 
the last but one is always the smallest, and the last the longest, 
though the length of it varies so much that, in some individuals 
of the Danish species, it is less than that of the two preceding 
ones together, whilst im others it almost equals that of the four 
preceding ones.
