larvae. Some observations were made during the summer on the 
occurrence of different species of mosquitoes. Here, in Logans- 
port, all specimens seen were Culex fatigans, while away from the 
city, and especially about the small pools and shaded hill-side 
springs, specimens of the genus Anopheles (punctipennis and 
maculipennis) are abundant. 
MOSQUITOES IN SPIDER SNARES. 
Dr. Durham sends the following note from Selangor, in regard 
to mosquitoes being caught in spiders’ webs :— 
Generally speaking, it is not usual to find Gnats or Midges 
thus caught—indeed they may be seen to settle on them and to 
fly away again. ‘In a house at Taiping (Perak),” writes Dr. 
Durham, “there was a small spider (perhaps about 4 im.) which 
lived in tiny holes or defects on the surface of the plaster walls 
of the house (outside). Around this was a circular snare about 
the area of a crown piece, fairly closely woven of exceedingly 
delicate threads ; at a short distance these snares merely looked 
like dirty or mildewy patches on the wall. Mosquitoes, midges, 
and Tineid moths seemed to be the prey; they were caught by 
entanglement of the feet, and sometimes were quite set out as 
on a mounting-card. The design is no doubt good for catching 
such insects which fly against a wall, and snares had as many as 
a dozen or more mosquitoes in them. I have not found the same 
beast again in houses, and regret I did not take any specimens.” 
MOSQUITOES FEEDING ON A CORPSE. 
Dr. Durham has also observed mosquitoes feeding on a corpse. 
He writes: “On 11th August, 1902, when performing autopsy 
on a Chinaman—dead three hours—a 8S. fasciaia (of which there 
were several about) settled on inner side of thigh and started to 
feed ; it was allowed to fill itself nearly, in order to be sure that 
it was sucking, and then was squashed.” 
VARIATION IN WING-MARKINGS AND IN POSITION 
OF THE CROSS-VEINS. 
Captain James writes, that “the same mosquito shows 
different markings at different seasons of the year. For example, 
I have caught a good number of A. /fuliginosws here in Madras 
this month (March). The markings on the wings of all of these
