species with similar wing ornamentation and general structure in 
which the palpi are markedly distinct, viz., P. costalis, Loew, 
and P. Marshallii, Theobald, and it may prove that at some 
future date we shall find them to be the same; the palpi are so 
strongly contrasted that they, together with other slight differences, 
compelled me to separate the two as distinct species. 
FOREIGN TERMS FOR MOSQUITOES. 
Besides. those given on p. 90, Vol. I., we may add the 
following :—“ Mutchers,” Hindustani. 
THE LENGTH OF TIME STEGOMYIA EGGS CAN 
WITHSTAND DESICCATION. 
Through the kindness of Dr. Finlay, I received some ova of 
Stegomyia fasciata from Cuba, Owing to stress of work these 
were neglected, being left in the dry glass tube for two months 
after their arrival in the country. Out of curiosity, I placed 
them in water, with the chill off, in a greenhouse. About 
12 oclock a.m., the next day, most of the eggs had hatched and 
the larvae were very active. Out of about fifty, only six reached 
the pupal stage, and these produced one female and five males. 
The eggs of Culicidae can probably ali remain dormant under 
such circumstances; so that should a pool dry up before they 
hatch, the eggs may not be destroyed, water apparently being 
essential for the incubation. It is therefore not at all impossible 
that Anopheles, etc., may, under stress of circumstances, lay their 
ova on dry surfaces. 
CLASSIFICATION OF CULICIDAE BY THE PALPAL 
JOINTING. 
M. Neveu-Lemaire, whilst following in many respects my 
grouping of the Culicidae, formulates a classification mainly based 
on the number of joints in the palpi of the 9 and the venation.* 
By taking these characters, he still upholds certain genera I 
proposed and based almost entirely on scale structure. But if 
the palpal structure, good as it is, is adhered to, we must 
give up ordinary dry specimens and let their place be taken 
by balsam preparations. This is surely going the wrong way,
