318 INSECTA, 
M. Robineau Desvoidy, in his “ Essai sur la tribu des Cuculides,” 
has added three others. 
The species in which the palpi (labial, according to his theory) 
are shorter than the proboscis, and where the intermediate tibie and 
tarsi are dilated and densely ciliated are designated collectively by 
the generic appellation of Sanerues*. Those in which the pro- 
boscis is elongated and recurved at the end, and where the palpi, also 
short, have the first joint thickest, the other shortest, and the three 
others cylindrical, form the genus Mrecaruinus t. According to the 
same author, the Culex ciliatus of Fabricius should form another, 
his PsororHora {. The ocelliare very distinct, and the legs of the 
female are ciliated; but the principal character consists in the pre- 
sence of two httle appendages situated on the prothorax, one on 
each side. They appeared to us to be formed by the dilatation of 
the lateral extremities of the segment. M. Desvoidy, in relation to 
this subject, quotes a similar observation made on a species of Psy- 
choda by M. Leon Dufour, communicated to him by me. But he 1s 
mistaken in saying that it had never been published—we noticed it 
in the first edition of this work, in the article Rhipiptera, and in that 
of Psychoda. 
In the other Nemocera, the proboscis is either very short and ter- 
minated by two large lips, or in the form of a siphon or rostrum, 
but directed perpendicularly or curved on the pectus. The palpi are 
bent underneath, or turned up, but in that case, from one to two 
joints only. 
Linnzus comprised them in his genus 
Taputa.-—Tiputans, Lat., 
Which we will divide in the following manner : 
We form a first section with those species in which the antenne 
are evidently longer than the head, at least in the males, slender, 
filiform or setaceous, and composed of more than twelve joints in the 
greater number, and where the legs are long and slender. 
Of these, some always furnished with wings, never present ocelli. 
The palpi are always short. The head is not (or but very slightly) 
prolonged anteriorly. The wings are laid flat, or tectiform, and have 
generally but few nervures that are longitudinal, divergent, and free 
posteriorly. The eyes are lunate, and the tibiee without spines. 
This subdivision consists of small species, which, while larve and 
nymphs, inhabit the water, or vegetable galls. 
Sometimes the antennz are entirely covered with hairs, iongest in 
the males, and forming a triangular tuft. 
Most of their larve live in the water, and are allied to those of 
the Culices. Some have false feet. Others, besides, have appen-
