Larva. — Head elongate, rounded, narrowed before ; eye very small, round ; an- 

 tennre short, not exceeding the mouth, all brown-black. Body as usual, hairs of first 

 two abdominal segments long and branched ; the others markedly shorter ; dorsal 

 fan shaped tufts present on segments 3-7, but small and with the branches filiform. 

 Air tube sessile, projecting backward over the anal segment, the comb on the side of 

 the eighth segment with 12 long, stout teeth, all practically equal in length without 

 any short ones interpolated. Anal segment with a heavy dark plate reaching half 

 way down the sides : dorsal tuft of four branched hairs, ventral brush of long plumed 

 hairs somewhat curved, the barred area surrounded by a chitinous rim, which runs 

 narrowly to base on ventral line. 



Voracity of Psorophora ciliata Fab. — Some forty young larvae 

 of P. ciliata were collected from a temporary roadside puddle at 

 Grassymead, Va., together with an equal number of Culex jamaicensis 

 on June 11. They devoured all iht Jamaicensis and had begun to 

 eat each other by the next morning. A large culture of Culex atro- 

 palpus was given them, which they despatched before night of the 

 twelfth and began to eat each other again. As their numbers were 

 being seriously reduced by their cannabalistic habits, they were then 

 separated in jars and fed a mixed culture of Culex restuans and C. 

 pipiens from a water barrel. Development was very rapid, pupae being 

 obtained by June 18. 



Larva of T^niorhynchus signipennis Coq. — This species was 

 bred at Laredo, Tex., by Dr. T. D. Berry. The larvae were found 

 in a puddle two days after a rain, pupae were formed on the fourth 

 day and imagoes on the fifth. The larvae are very closely allied to 

 Culex jamaicensis, differing only in minor details. Their mode of 

 occurrence and rapid development are likewise similar. As compared 

 with jamaicensis the upper two hair tufts of the head are single hairs, 

 not tufts of five or six ; the antennae are all pale whitish, not with the 

 terminal two thirds black ; the four spines of the air tube are very 

 basally placed, not remotely spaced to reach nearly half the length of 

 the tube. There are other smaller differences. 



Occurrence of Culex aurifer Coq. — The note with this head- 

 ing printed on page 172 of this Journal as in fault, owing to a misread- 

 ing of Mr. Brakeley's letter. He now writes me that it wa? the 

 adults, not the larvae, that occurred in the fore bay (erroneously 

 printed " five boy " ) of his dam. I have taken the adults sparingly 

 at Weekapaug, R. L, near some cold springs in pasture land, in July. 

 The larvae had, of course, all disappeared before that date.
